The SCAP Security Guide Project
https://www.open-scap.org/security-policies/scap-security-guide
This guide presents a catalog of security-relevant configuration settings for Red Hat Enterprise Linux CoreOS 4. It is a rendering of content structured in the eXtensible Configuration Checklist Description Format (XCCDF) in order to support security automation. The SCAP content is is available in the `scap-security-guide` package which is developed at https://www.open-scap.org/security-policies/scap-security-guide.
Providing system administrators with such guidance informs them how to securely configure systems under their control in a variety of network roles. Policy makers and baseline creators can use this catalog of settings, with its associated references to higher-level security control catalogs, in order to assist them in security baseline creation. This guide is a catalog, not a checklist, and satisfaction of every item is not likely to be possible or sensible in many operational scenarios. However, the XCCDF format enables granular selection and adjustment of settings, and their association with OVAL and OCIL content provides an automated checking capability. Transformations of this document, and its associated automated checking content, are capable of providing baselines that meet a diverse set of policy objectives. Some example XCCDF Profiles, which are selections of items that form checklists and can be used as baselines, are available with this guide. They can be processed, in an automated fashion, with tools that support the Security Content Automation Protocol (SCAP). The DISA STIG, which provides required settings for US Department of Defense systems, is one example of a baseline created from this guidance.
Do not attempt to implement any of the settings in this guide without first testing them in a non-operational environment. The creators of this guidance assume no responsibility whatsoever for its use by other parties, and makes no guarantees, expressed or implied, about its quality, reliability, or any other characteristic.

## Checklist

Group Guide to the Secure Configuration of Red Hat Enterprise Linux CoreOS 4 Group contains 31 groups and 118 rules
Group System Settings Group contains 14 groups and 18 rules
[ref] Contains rules that check correct system settings.
Group Installing and Maintaining Software Group contains 1 group and 1 rule
[ref] The following sections contain information on security-relevant choices during the initial operating system installation process and the setup of software updates.
Group Disk Partitioning Group contains 1 rule
[ref] To ensure separation and protection of data, there are top-level system directories which should be placed on their own physical partition or logical volume. The installer's default partitioning scheme creates separate logical volumes for `/`, `/boot`, and `swap`. If starting with any of the default layouts, check the box to \"Review and modify partitioning.\" This allows for the easy creation of additional logical volumes inside the volume group already created, though it may require making `/`'s logical volume smaller to create space. In general, using logical volumes is preferable to using partitions because they can be more easily adjusted later. If creating a custom layout, create the partitions mentioned in the previous paragraph (which the installer will require anyway), as well as separate ones described in the following sections. If a system has already been installed, and the default partitioning scheme was used, it is possible but nontrivial to modify it to create separate logical volumes for the directories listed above. The Logical Volume Manager (LVM) makes this possible.
#### Rule Ensure /var/log/audit Located On Separate Partition [ref]
Audit logs are stored in the `/var/log/audit` directory. Partitioning Red Hat CoreOS is a Day 1 operation and cannot be changed afterwards. For documentation on how to add a MachineConfig manifest that specifies a separate `/var/log/audit` partition, follow: https://docs.openshift.com/container-platform/latest/installing/installing_platform_agnostic/installing-platform-agnostic.html#installation-user-infra-machines-advanced_disk_installing-platform-agnostic Note that the Red Hat OpenShift documentation often references a block device, such as `/dev/vda`. The name of the available block devices depends on the underlying infrastructure (bare metal vs cloud), and often the specific instance type. For example in AWS, some instance types have NVMe drives (`/dev/nvme*`), others use `/dev/xvda*`. You will need to look for relevant documentation for your infrastructure around this. In many cases, the simplest thing is to boot a single machine with an Ignition configuration that just gives you SSH access, and inspect the block devices via e.g. the `lsblk` command. For physical hardware, a good best practice is to reference devices via the `/dev/disk/by-id/` or `/dev/disk/by-path` links. Make absolutely certain that it is large enough to store all audit logs that will be created by the auditing daemon.
Rationale: | Placing `/var/log/audit` in its own partition enables better separation between audit files and other files, and helps ensure that auditing cannot be halted due to the partition running out of space.

Group GRUB2 bootloader configuration Group contains 1 rule
[ref] During the boot process, the boot loader is responsible for starting the execution of the kernel and passing options to it. The boot loader allows for the selection of different kernels - possibly on different partitions or media. The default Red Hat Enterprise Linux CoreOS 4 boot loader for x86 systems is called GRUB2. Options it can pass to the kernel include single-user mode, which provides root access without any authentication, and the ability to disable SELinux. To prevent local users from modifying the boot parameters and endangering security, protect the boot loader configuration with a password and ensure its configuration file's permissions are set properly.
#### Rule Disable vsyscalls [ref]
To disable use of virtual syscalls, add the argument `vsyscall=none` to all BLS (Boot Loader Specification) entries ('options' line) for the Linux operating system in `/boot/loader/entries/*.conf`.
Rationale: | Virtual Syscalls provide an opportunity of attack for a user who has control of the return instruction pointer.

Group Configure Syslog Group contains 1 group and 3 rules
[ref] The syslog service has been the default Unix logging mechanism for many years. It has a number of downsides, including inconsistent log format, lack of authentication for received messages, and lack of authentication, encryption, or reliable transport for messages sent over a network. However, due to its long history, syslog is a de facto standard which is supported by almost all Unix applications. In Red Hat Enterprise Linux CoreOS 4, rsyslog has replaced ksyslogd as the syslog daemon of choice, and it includes some additional security features such as reliable, connection-oriented (i.e. TCP) transmission of logs, the option to log to database formats, and the encryption of log data en route to a central logging server. This section discusses how to configure rsyslog for best effect, and how to use tools provided with the system to maintain and monitor logs.
Group systemd-journald Group contains 3 rules
[ref] systemd-journald is a system service that collects and stores logging data. It creates and maintains structured, indexed journals based on logging information that is received from a variety of sources. For more information on `systemd-journald` and additional `systemd-journald` configuration options, see https://systemd.io/.
#### Rule Verify Group Who Owns the system journal [ref]
' To properly set the group owner of `/var/log/journal/.*/system.journal`, run the command:
    $ sudo chgrp systemd-journal /var/log/journal/.*/system.journal

Group File Permissions and Masks Group contains 7 groups and 10 rules
[ref] Traditional Unix security relies heavily on file and directory permissions to prevent unauthorized users from reading or modifying files to which they should not have access. Several of the commands in this section search filesystems for files or directories with certain characteristics, and are intended to be run on every local partition on a given system. When the variable PART appears in one of the commands below, it means that the command is intended to be run repeatedly, with the name of each local partition substituted for PART in turn. The following command prints a list of all xfs partitions on the local system, which is the default filesystem for Red Hat Enterprise Linux CoreOS 4 installations:
    $ mount -t xfs | awk '{print $3}'
For any systems that use a different local filesystem type, modify this command as appropriate.
Group Verify Permissions on Important Files and Directories Group contains 1 group and 3 rules
[ref] Permissions for many files on a system must be set restrictively to ensure sensitive information is properly protected. This section discusses important permission restrictions which can be verified to ensure that no harmful discrepancies have arisen.
Group Verify Permissions on Files within /var/log Directory Group contains 3 rules
[ref] The `/var/log` directory contains files with logs of error messages in the system and should only be accessed by authorized personnel.
#### Rule Verify Group Who Owns /var/log Directory [ref]
To properly set the group owner of `/var/log`, run the command:
    $ sudo chgrp root /var/log
Rationale: | The `/var/log` directory contains files with logs of error messages in the system and should only be accessed by authorized personnel.

Group Restrict Dynamic Mounting and Unmounting of Filesystems Group contains 1 rule
[ref] Linux includes a number of facilities for the automated addition and removal of filesystems on a running system. These facilities may be necessary in many environments, but this capability also carries some risk -- whether direct risk from allowing users to introduce arbitrary filesystems, or risk that software flaws in the automated mount facility itself could allow an attacker to compromise the system. This command can be used to list the types of filesystems that are available to the currently executing kernel:
    $ find /lib/modules/`uname -r`/kernel/fs -type f -name '*.ko'
If these filesystems are not required then they can be explicitly disabled in a configuratio file in `/etc/modprobe.d`.
#### Rule Disable Modprobe Loading of USB Storage Driver [ref]
To prevent USB storage devices from being used, configure the kernel module loading system to prevent automatic loading of the USB storage driver. To configure the system to prevent the `usb-storage` kernel module from being loaded, add the following line to the file `/etc/modprobe.d/usb-storage.conf`:
    install usb-storage /bin/false
This entry will cause a non-zero return value during a `usb-storage` module installation and additionally convey the meaning of the entry to the user in form of an error message. If you would like to omit a non-zero return value and an error message, you may want to add a different line instead (both `/bin/true` and `/bin/false` are allowed by OVAL and will be accepted by the scan):
    install usb-storage /bin/true
This will prevent the `modprobe` program from loading the `usb-storage` module, but will not prevent an administrator (or another program) from using the `insmod` program to load the module manually.
Rationale: | USB storage devices such as thumb drives can be used to introduce malicious software.

Group Restrict Programs from Dangerous Execution Patterns Group contains 3 groups and 6 rules
[ref] The recommendations in this section are designed to ensure that the system's features to protect against potentially dangerous program execution are activated. These protections are applied at the system initialization or kernel level, and defend against certain types of badly-configured or compromised programs.
Group Enable ExecShield Group contains 1 rule
[ref] ExecShield describes kernel features that provide protection against exploitation of memory corruption errors such as buffer overflows. These features include random placement of the stack and other memory regions, prevention of execution in memory that should only hold data, and special handling of text buffers. These protections are enabled by default on 32-bit systems and controlled through `sysctl` variables `kernel.exec-shield` and `kernel.randomize_va_space`. On the latest 64-bit systems, `kernel.exec-shield` cannot be enabled or disabled with `sysctl`.
#### Rule Enable Randomized Layout of Virtual Address Space [ref]
To set the runtime status of the `kernel.randomize_va_space` kernel parameter, run the following command:
    $ sudo sysctl -w kernel.randomize_va_space=2
To make sure that the setting is persistent, add the following line to a file in the directory `/etc/sysctl.d`:
    kernel.randomize_va_space = 2
Rationale: | Address space layout randomization (ASLR) makes it more difficult for an attacker to predict the location of attack code they have introduced into a process's address space during an attempt at exploitation. Additionally, ASLR makes it more difficult for an attacker to know the location of existing code in order to re-purpose it using return oriented programming (ROP) techniques.

Group Enable Execute Disable (XD) or No Execute (NX) Support on x86 Systems Group contains 1 rule
[ref] Recent processors in the x86 family support the ability to prevent code execution on a per memory page basis. Generically and on AMD processors, this ability is called No Execute (NX), while on Intel processors it is called Execute Disable (XD). This ability can help prevent exploitation of buffer overflow vulnerabilities and should be activated whenever possible. Extra steps must be taken to ensure that this protection is enabled, particularly on 32-bit x86 systems. Other processors, such as Itanium and POWER, have included such support since inception and the standard kernel for those platforms supports the feature. This is enabled by default on the latest Oracle Linux, Red Hat and Fedora systems if supported by the hardware.
#### Rule Enable NX or XD Support in the BIOS [ref]
Reboot the system and enter the BIOS or Setup configuration menu. Navigate the BIOS configuration menu and make sure that the option is enabled. The setting may be located under a Security section. Look for Execute Disable (XD) on Intel-based systems and No Execute (NX) on AMD-based systems.
Rationale: | Computers with the ability to prevent this type of code execution frequently put an option in the BIOS that will allow users to turn the feature on or off at will.

Group Memory Poisoning Group contains 2 rules
[ref] Memory Poisoning consists of writing a special value to uninitialized or freed memory. Poisoning can be used as a mechanism to prevent leak of information and detection of corrupted memory.
#### Rule Enable page allocator poisoning [ref]
To enable poisoning of free pages, add the argument `page_poison=1` to all BLS (Boot Loader Specification) entries ('options' line) for the Linux operating system in `/boot/loader/entries/*.conf`.
Rationale: | Poisoning writes an arbitrary value to freed pages, so any modification or reference to that page after being freed or before being initialized will be detected and prevented. This prevents many types of use-after-free vulnerabilities at little performance cost. Also prevents leak of data and detection of corrupted memory.

Group SELinux Group contains 3 rules
[ref] SELinux is a feature of the Linux kernel which can be used to guard against misconfigured or compromised programs. SELinux enforces the idea that programs should be limited in what files they can access and what actions they can take. The default SELinux policy, as configured on Red Hat Enterprise Linux CoreOS 4, has been sufficiently developed and debugged that it should be usable on almost any system with minimal configuration and a small amount of system administrator training. This policy prevents system services - including most of the common network-visible services such as mail servers, FTP servers, and DNS servers - from accessing files which those services have no valid reason to access. This action alone prevents a huge amount of possible damage from network attacks against services, from trojaned software, and so forth. This guide recommends that SELinux be enabled using the default (targeted) policy on every Red Hat Enterprise Linux CoreOS 4 system, unless that system has unusual requirements which make a stronger policy appropriate.
#### Rule Ensure SELinux Not Disabled in the kernel arguments [ref]
SELinux can be disabled at boot time by disabling it via a kernel argument. Remove any instances of `selinux=0` from the kernel arguments in that file to prevent SELinux from being disabled at boot.
Rationale: | Disabling a major host protection feature, such as SELinux, at boot time prevents it from confining system services at boot time. Further, it increases the chances that it will remain off during system operation.

#### Rule Configure SELinux Policy [ref]
The SELinux `targeted` policy is appropriate for general-purpose desktops and servers, as well as systems in many other roles. To configure the system to use this policy, add or correct the following line in `/etc/selinux/config`:
    SELINUXTYPE=targeted
Other policies, such as `mls`, provide additional security labeling and greater confinement but are not compatible with many general-purpose use cases.
Rationale: | Setting the SELinux policy to `targeted` or a more specialized policy ensures the system will confine processes that are likely to be targeted for exploitation, such as network or system services. Note: During the development or debugging of SELinux modules, it is common to temporarily place non-production systems in `permissive` mode. In such temporary cases, SELinux policies should be developed, and once work is completed, the system should be reconfigured to `targeted`.

Group Services Group contains 4 groups and 8 rules
[ref] The best protection against vulnerable software is running less software. This section describes how to review the software which Red Hat Enterprise Linux CoreOS 4 installs on a system and disable software which is not needed. It then enumerates the software packages installed on a default Red Hat Enterprise Linux CoreOS 4 system and provides guidance about which ones can be safely disabled. Red Hat Enterprise Linux CoreOS 4 provides a convenient minimal install option that essentially installs the bare necessities for a functional system. When building Red Hat Enterprise Linux CoreOS 4 systems, it is highly recommended to select the minimal packages and then build up the system from there.
Group Network Time Protocol Group contains 2 rules
[ref] The Network Time Protocol is used to manage the system clock over a network. Computer clocks are not very accurate, so time will drift unpredictably on unmanaged systems. Central time protocols can be used both to ensure that time is consistent among a network of systems, and that their time is consistent with the outside world. If every system on a network reliably reports the same time, then it is much easier to correlate log messages in case of an attack. In addition, a number of cryptographic protocols (such as Kerberos) use timestamps to prevent certain types of attacks. If your network does not have synchronized time, these protocols may be unreliable or even unusable. Depending on the specifics of the network, global time accuracy may be just as important as local synchronization, or not very important at all. If your network is connected to the Internet, using a public timeserver (or one provided by your enterprise) provides globally accurate timestamps which may be essential in investigating or responding to an attack which originated outside of your network. A typical network setup involves a small number of internal systems operating as NTP servers, and the remainder obtaining time information from those internal servers. There is a choice between the daemons `ntpd` and `chronyd`, which are available from the repositories in the `ntp` and `chrony` packages respectively. The default `chronyd` daemon can work well when external time references are only intermittently accessible, can perform well even when the network is congested for longer periods of time, can usually synchronize the clock faster and with better time accuracy, and quickly adapts to sudden changes in the rate of the clock, for example, due to changes in the temperature of the crystal oscillator. `Chronyd` should be considered for all systems which are frequently suspended or otherwise intermittently disconnected and reconnected to a network. Mobile and virtual systems for example. The `ntpd` NTP daemon fully supports NTP protocol version 4 (RFC 5905), including broadcast, multicast, manycast clients and servers, and the orphan mode. It also supports extra authentication schemes based on public-key cryptography (RFC 5906). The NTP daemon (`ntpd`) should be considered for systems which are normally kept permanently on. Systems which are required to use broadcast or multicast IP, or to perform authentication of packets with the `Autokey` protocol, should consider using `ntpd`. Refer to https://en.wikipedia.org/wiki/Network_Time_Protocol for more detailed comparison of features of `chronyd` and `ntpd` daemon features respectively, and for further guidance how to choose between the two NTP daemons. The upstream manual pages at https://chrony-project.org/documentation.html for `chronyd` and http://www.ntp.org for `ntpd` provide additional information on the capabilities and configuration of each of the NTP daemons.
#### Rule Enable the NTP Daemon [ref]
As a user with administrator privileges, log into a node in the relevant pool:
    $ oc debug node/$NODE_NAME
At the
    sh-4.4#
prompt, run:
    # chroot /host
Run the following command to determine the current status of the `chronyd` service:
    $ sudo systemctl is-active chronyd
If the service is running, it should return the following:
    active
Note: The `chronyd` daemon is enabled by default. As a user with administrator privileges, log into a node in the relevant pool:
    $ oc debug node/$NODE_NAME
At the
    sh-4.4#
prompt, run:
    # chroot /host
Run the following command to determine the current status of the `ntpd` service:
    $ sudo systemctl is-active ntpd
If the service is running, it should return the following:
    active
Note: The `ntpd` daemon is not enabled by default. Though as mentioned in the previous sections in certain environments the `ntpd` daemon might be preferred to be used rather than the `chronyd` one. Refer to: for guidance which NTP daemon to choose depending on the environment used.
Rationale: | Enabling some of `chronyd` or `ntpd` services ensures that the NTP daemon will be running and that the system will synchronize its time to any servers specified. This is important whether the system is configured to be a client (and synchronize only its own clock) or it is also acting as an NTP server to other systems. Synchronizing time is essential for authentication services such as Kerberos, but it is also important for maintaining accurate logs and auditing possible security breaches. The `chronyd` and `ntpd` NTP daemons offer all of the functionality of `ntpdate`, which is now deprecated.

#### Rule Specify a Remote NTP Server [ref]
Depending on specific functional requirements of a concrete production environment, the Red Hat Enterprise Linux CoreOS 4 system can be configured to utilize the services of the `chronyd` NTP daemon (the default), or services of the `ntpd` NTP daemon. Refer to for more detailed comparison of the features of both of the choices, and for further guidance how to choose between the two NTP daemons. To specify a remote NTP server for time synchronization, perform the following: if the system is configured to use the `chronyd` as the NTP daemon (the default), edit the file `/etc/chrony.conf` as follows, if the system is configured to use the `ntpd` as the NTP daemon, edit the file `/etc/ntp.conf` as documented below. Add or correct the following lines, substituting the IP or hostname of a remote NTP server for ntpserver:
    server ntpserver
This instructs the NTP software to contact that remote server to obtain time data. Note that if the remediation shipping with this content is being used, the MachineConfig shipped does not include reference NTP servers to point to. It is up to the admin to set these which will vary depending on the cluster's requirements. The aforementioned remediation does include the directory `/etc/chrony.d` which would allow the creation of configuration files to set these servers. If we'd like to set a configuration like the following:
    pool 2.rhel.pool.ntp.org iburst

    server 0.rhel.pool.ntp.org minpoll 4 maxpoll 10
    server 1.rhel.pool.ntp.org minpoll 4 maxpoll 10
    server 2.rhel.pool.ntp.org minpoll 4 maxpoll 10
    server 3.rhel.pool.ntp.org minpoll 4 maxpoll 10
This could be done with to the following manifest:

Group SSH Server Group contains 1 group and 2 rules
[ref] The SSH protocol is recommended for remote login and remote file transfer. SSH provides confidentiality and integrity for data exchanged between two systems, as well as server authentication, through the use of public key cryptography. The implementation included with the system is called OpenSSH, and more detailed documentation is available from its website, https://www.openssh.com. Its server program is called `sshd` and provided by the RPM package `openssh-server`.
Group Configure OpenSSH Server if Necessary Group contains 1 rule
[ref] If the system needs to act as an SSH server, then certain changes should be made to the OpenSSH daemon configuration file `/etc/ssh/sshd_config`. The following recommendations can be applied to this file. See the `sshd_config(5)` man page for more detailed information.
#### Rule Disable SSH Root Login [ref]
The root user should never be allowed to login to a system directly over a network. To disable root login via SSH, add or correct the following line in `/etc/ssh/sshd_config.d/00-complianceascode-hardening.conf`:
    PermitRootLogin no
Rationale: | Even though the communications channel may be encrypted, an additional layer of security is gained by extending the policy of not logging directly on as root. In addition, logging in with a user-specific account provides individual accountability of actions performed on the system and also helps to minimize direct attack attempts on root's password.

#### Rule Disable SSH Server If Possible [ref]
Instead of using ssh to remotely log in to a cluster node, it is recommended to use `oc debug` The `sshd` service can be disabled with the following manifest:
    ---
    apiVersion: machineconfiguration.openshift.io/v1
    kind: MachineConfig
    metadata:
      labels:
        machineconfiguration.openshift.io/role: master
      name: 75-master-sshd-disable
    spec:
      config:
        ignition:
          version: 3.1.0
        systemd:
          units:
          - name: sshd.service
            enabled: false
            mask: true
          - name: sshd.socket
            enabled: false
            mask: true
This will disable the `sshd` service in all the nodes labeled with the "master" role. Note that this needs to be done for each `MachineConfigPool` For more information on how to configure nodes with the Machine Config Operator see the relevant documentation.
Rationale: | Red Hat Enterprise Linux CoreOS (RHCOS) is a single-purpose container operating system. RHCOS is only supported as a component of the OpenShift Container Platform. Remote management of the RHCOS nodes is performed at the OpenShift Container Platform API level. As a result, any direct remote access to the RHCOS nodes is unnecessary. Disabling the SSHD service helps reduce the number of open ports on each host.

Group USBGuard daemon Group contains 4 rules
[ref] The USBGuard daemon enforces the USB device authorization policy for all USB devices.
#### Rule Install usbguard Package [ref]
The `usbguard` package can be installed with the following manifest:
    ---
    apiVersion: machineconfiguration.openshift.io/v1
    kind: MachineConfig
    metadata:
      labels:
        machineconfiguration.openshift.io/role: master

    spec:
      config:
        ignition:
          version: 3.1.0
      extensions:
        - usbguard
This will install the `usbguard` package in all the nodes labeled with the "master" role. Note that this needs to be done for each `MachineConfigPool` For more information on how to configure nodes with the Machine Config Operator see the relevant documentation.
Rationale: | `usbguard` is a software framework that helps to protect against rogue USB devices by implementing basic whitelisting/blacklisting capabilities based on USB device attributes.

#### Rule Log USBGuard daemon audit events using Linux Audit [ref]
To configure USBGuard daemon to log via Linux Audit (as opposed directly to a file), `AuditBackend` option in `/etc/usbguard/usbguard-daemon.conf` needs to be set to `LinuxAudit`.
Rationale: | Using the Linux Audit logging allows for centralized trace of events.

#### Rule Authorize Human Interface Devices and USB hubs in USBGuard daemon [ref]
To allow authorization of USB devices combining human interface device and hub capabilities by USBGuard daemon, add the line `allow with-interface match-all { 03:*:* 09:00:* }` to `/etc/usbguard/rules.conf`. Warning: This rule should be understood primarily as a convenience administration feature. This rule ensures that if the USBGuard default rules.conf file is present, it will alter it so that USB human interface devices and hubs are allowed. However, if the rules.conf file is altered by system administrator, the rule does not check if USB human interface devices and hubs are allowed. This assumes that an administrator modified the file with some purpose in mind.
Rationale: | Without allowing Human Interface Devices, it might not be possible to interact with the system. Without allowing hubs, it might not be possible to use any USB devices on the system.

Group System Accounting with auditd Group contains 10 groups and 92 rules
[ref] The audit service provides substantial capabilities for recording system activities. By default, the service audits about SELinux AVC denials and certain types of security-relevant events such as system logins, account modifications, and authentication events performed by programs such as sudo. Under its default configuration, `auditd` has modest disk space requirements, and should not noticeably impact system performance. NOTE: The Linux Audit daemon `auditd` can be configured to use the `augenrules` program to read audit rules files (`*.rules`) located in `/etc/audit/rules.d` location and compile them to create the resulting form of the `/etc/audit/audit.rules` configuration file during the daemon startup (default configuration). Alternatively, the `auditd` daemon can use the `auditctl` utility to read audit rules from the `/etc/audit/audit.rules` configuration file during daemon startup, and load them into the kernel. The expected behavior is configured via the appropriate `ExecStartPost` directive setting in the `/usr/lib/systemd/system/auditd.service` configuration file. To instruct the `auditd` daemon to use the `augenrules` program to read audit rules (default configuration), use the following setting:
    ExecStartPost=-/sbin/augenrules --load
in the `/usr/lib/systemd/system/auditd.service` configuration file. In order to instruct the `auditd` daemon to use the `auditctl` utility to read audit rules, use the following setting:
    ExecStartPost=-/sbin/auditctl -R /etc/audit/audit.rules
in the `/usr/lib/systemd/system/auditd.service` configuration file. Refer to `[Service]` section of the `/usr/lib/systemd/system/auditd.service` configuration file for further details. Government networks often have substantial auditing requirements and `auditd` can be configured to meet these requirements. Examining some example audit records demonstrates how the Linux audit system satisfies common requirements. The following example from Red Hat Enterprise Linux 7 Documentation available at `https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html-single/selinux_users_and_administrators_guide/index#sect-Security-Enhanced_Linux-Fixing_Problems-Raw_Audit_Messages` shows the substantial amount of information captured in a two typical "raw" audit messages, followed by a breakdown of the most important fields. In this example the message is SELinux-related and reports an AVC denial (and the associated system call) that occurred when the Apache HTTP Server attempted to access the `/var/www/html/file1` file (labeled with the `samba_share_t` type):
    type=AVC msg=audit(1226874073.147:96): avc:  denied  { getattr } for pid=2465 comm="httpd"
    path="/var/www/html/file1" dev=dm-0 ino=284133 scontext=unconfined_u:system_r:httpd_t:s0
    tcontext=unconfined_u:object_r:samba_share_t:s0 tclass=file

    type=SYSCALL msg=audit(1226874073.147:96): arch=40000003 syscall=196 success=no exit=-13
    a0=b98df198 a1=bfec85dc a2=54dff4 a3=2008171 items=0 ppid=2463 pid=2465 auid=502 uid=48
    gid=48 euid=48 suid=48 fsuid=48 egid=48 sgid=48 fsgid=48 tty=(none) ses=6 comm="httpd"
    exe="/usr/sbin/httpd" subj=unconfined_u:system_r:httpd_t:s0 key=(null)
`msg=audit(1226874073.147:96)` The number in parentheses is the unformatted time stamp (Epoch time) for the event, which can be converted to standard time by using the `date` command. `{ getattr }` The item in braces indicates the permission that was denied. `getattr` indicates the source process was trying to read the target file's status information. This occurs before reading files. This action is denied due to the file being accessed having the wrong label. Commonly seen permissions include `getattr`, `read`, and `write`. `comm="httpd"` The executable that launched the process. The full path of the executable is found in the `exe=` section of the system call (`SYSCALL`) message, which in this case, is `exe="/usr/sbin/httpd"`. `path="/var/www/html/file1"` The path to the object (target) the process attempted to access. `scontext="unconfined_u:system_r:httpd_t:s0"` The SELinux context of the process that attempted the denied action. In this case, it is the SELinux context of the Apache HTTP Server, which is running in the `httpd_t` domain. `tcontext="unconfined_u:object_r:samba_share_t:s0"` The SELinux context of the object (target) the process attempted to access. In this case, it is the SELinux context of `file1`. Note: the `samba_share_t` type is not accessible to processes running in the `httpd_t` domain. From the system call (`SYSCALL`) message, two items are of interest: `success=no`: indicates whether the denial (AVC) was enforced or not. `success=no` indicates the system call was not successful (SELinux denied access). `success=yes` indicates the system call was successful - this can be seen for permissive domains or unconfined domains, such as `initrc_t` and `kernel_t`. `exe="/usr/sbin/httpd"`: the full path to the executable that launched the process, which in this case, is `exe="/usr/sbin/httpd"`.
Group Configure auditd Rules for Comprehensive Auditing Group contains 7 groups and 81 rules
[ref] The `auditd` program can perform comprehensive monitoring of system activity. This section describes recommended configuration settings for comprehensive auditing, but a full description of the auditing system's capabilities is beyond the scope of this guide. The mailing list linux-audit@redhat.com exists to facilitate community discussion of the auditing system. The audit subsystem supports extensive collection of events, including: Tracing of arbitrary system calls (identified by name or number) on entry or exit. Filtering by PID, UID, call success, system call argument (with some limitations), etc. Monitoring of specific files for modifications to the file's contents or metadata. Auditing rules at startup are controlled by the file `/etc/audit/audit.rules`. Add rules to it to meet the auditing requirements for your organization. Each line in `/etc/audit/audit.rules` represents a series of arguments that can be passed to `auditctl` and can be individually tested during runtime. See documentation in `/usr/share/doc/audit-VERSION` and in the related man pages for more details. If copying any example audit rulesets from `/usr/share/doc/audit-VERSION`, be sure to comment out the lines containing `arch=` which are not appropriate for your system's architecture. Then review and understand the following rules, ensuring rules are activated as needed for the appropriate architecture. After reviewing all the rules, reading the following sections, and editing as needed, the new rules can be activated as follows:
    $ sudo service auditd restart
Group Record Events that Modify the System's Discretionary Access Controls Group contains 15 rules
[ref] At a minimum, the audit system should collect file permission changes for all users and root. Note that the "-F arch=b32" lines should be present even on a 64 bit system. These commands identify system calls for auditing. Even if the system is 64 bit it can still execute 32 bit system calls. Additionally, these rules can be configured in a number of ways while still achieving the desired effect. An example of this is that the "-S" calls could be split up and placed on separate lines, however, this is less efficient. Add the following to `/etc/audit/audit.rules`:
    -a always,exit -F arch=b32 -S chmod,fchmod,fchmodat -F auid>=1000 -F auid!=unset -F key=perm_mod

        -a always,exit -F arch=b32 -S chown,fchown,fchownat,lchown -F auid>=1000 -F auid!=unset -F key=perm_mod
        -a always,exit -F arch=b32 -S setxattr,lsetxattr,fsetxattr,removexattr,lremovexattr,fremovexattr -F auid>=1000 -F auid!=unset -F key=perm_mod
If your system is 64 bit then these lines should be duplicated and the arch=b32 replaced with arch=b64 as follows:
    -a always,exit -F arch=b64 -S chmod,fchmod,fchmodat -F auid>=1000 -F auid!=unset -F key=perm_mod

        -a always,exit -F arch=b64 -S chown,fchown,fchownat,lchown -F auid>=1000 -F auid!=unset -F key=perm_mod
        -a always,exit -F arch=b64 -S setxattr,lsetxattr,fsetxattr,removexattr,lremovexattr,fremovexattr -F auid>=1000 -F auid!=unset -F key=perm_mod
#### Rule Record Events that Modify the System's Discretionary Access Controls - chmod [ref]
At a minimum, the audit system should collect file permission changes for all users and root. If the `auditd` daemon is configured to use the `augenrules` program to read audit rules during daemon startup (the default), add the following line to a file with suffix `.rules` in the directory `/etc/audit/rules.d`:
    -a always,exit -F arch=b32 -S chmod -F auid>=1000 -F auid!=unset -F key=perm_mod
If the system is 64 bit then also add the following line:
    -a always,exit -F arch=b64 -S chmod -F auid>=1000 -F auid!=unset -F key=perm_mod
If the `auditd` daemon is configured to use the `auditctl` utility to read audit rules during daemon startup, add the following line to `/etc/audit/audit.rules` file:
    -a always,exit -F arch=b32 -S chmod -F auid>=1000 -F auid!=unset -F key=perm_mod
If the system is 64 bit then also add the following line:
    -a always,exit -F arch=b64 -S chmod -F auid>=1000 -F auid!=unset -F key=perm_mod
Warning: Note that these rules can be configured in a number of ways while still achieving the desired effect. Here the system calls have been placed independent of other system calls. Grouping these system calls with others as identifying earlier in this guide is more efficient.

#### Rule Record Events that Modify the System's Discretionary Access Controls - fchmodat [ref]
At a minimum, the audit system should collect file permission changes for all users and root. If the `auditd` daemon is configured to use the `augenrules` program to read audit rules during daemon startup (the default), add the following line to a file with suffix `.rules` in the directory `/etc/audit/rules.d`:
    -a always,exit -F arch=b32 -S fchmodat -F auid>=1000 -F auid!=unset -F key=perm_mod
If the system is 64 bit then also add the following line:
    -a always,exit -F arch=b64 -S fchmodat -F auid>=1000 -F auid!=unset -F key=perm_mod
If the `auditd` daemon is configured to use the `auditctl` utility to read audit rules during daemon startup, add the following line to `/etc/audit/audit.rules` file:
    -a always,exit -F arch=b32 -S fchmodat -F auid>=1000 -F auid!=unset -F key=perm_mod
If the system is 64 bit then also add the following line:
    -a always,exit -F arch=b64 -S fchmodat -F auid>=1000 -F auid!=unset -F key=perm_mod
Warning: Note that these rules can be configured in a number of ways while still achieving the desired effect. Here the system calls have been placed independent of other system calls. Grouping these system calls with others as identifying earlier in this guide is more efficient.
Rationale: | The changing of file permissions could indicate that a user is attempting to gain access to information that would otherwise be disallowed. Auditing DAC modifications can facilitate the identification of patterns of abuse among both authorized and unauthorized users.

#### Rule Record Events that Modify the System's Discretionary Access Controls - fsetxattr [ref]
At a minimum, the audit system should collect file permission changes for all users and root. If the `auditd` daemon is configured to use the `augenrules` program to read audit rules during daemon startup (the default), add the following line to a file with suffix `.rules` in the directory `/etc/audit/rules.d`:
    -a always,exit -F arch=b32 -S fsetxattr -F auid>=1000 -F auid!=unset -F key=perm_mod
If the system is 64 bit then also add the following line:
    -a always,exit -F arch=b64 -S fsetxattr -F auid>=1000 -F auid!=unset -F key=perm_mod
If the `auditd` daemon is configured to use the `auditctl` utility to read audit rules during daemon startup, add the following line to `/etc/audit/audit.rules` file:
    -a always,exit -F arch=b32 -S fsetxattr -F auid>=1000 -F auid!=unset -F key=perm_mod
If the system is 64 bit then also add the following line:
    -a always,exit -F arch=b64 -S fsetxattr -F auid>=1000 -F auid!=unset -F key=perm_mod
Warning: Note that these rules can be configured in a number of ways while still achieving the desired effect. Here the system calls have been placed independent of other system calls. Grouping these system calls with others as identifying earlier in this guide is more efficient.
Rationale: | The changing of file permissions could indicate that a user is attempting to gain access to information that would otherwise be disallowed. Auditing DAC modifications can facilitate the identification of patterns of abuse among both authorized and unauthorized users.

#### Rule Record Events that Modify the System's Discretionary Access Controls - lsetxattr [ref]
At a minimum, the audit system should collect file permission changes for all users and root. If the `auditd` daemon is configured to use the `augenrules` program to read audit rules during daemon startup (the default), add the following line to a file with suffix `.rules` in the directory `/etc/audit/rules.d`:
    -a always,exit -F arch=b32 -S lsetxattr -F auid>=1000 -F auid!=unset -F key=perm_mod
If the system is 64 bit then also add the following line:
    -a always,exit -F arch=b64 -S lsetxattr -F auid>=1000 -F auid!=unset -F key=perm_mod
If the `auditd` daemon is configured to use the `auditctl` utility to read audit rules during daemon startup, add the following line to `/etc/audit/audit.rules` file:
    -a always,exit -F arch=b32 -S lsetxattr -F auid>=1000 -F auid!=unset -F key=perm_mod
If the system is 64 bit then also add the following line:
    -a always,exit -F arch=b64 -S lsetxattr -F auid>=1000 -F auid!=unset -F key=perm_mod
Warning: Note that these rules can be configured in a number of ways while still achieving the desired effect. Here the system calls have been placed independent of other system calls. Grouping these system calls with others as identifying earlier in this guide is more efficient.
Rationale: | The changing of file permissions could indicate that a user is attempting to gain access to information that would otherwise be disallowed. Auditing DAC modifications can facilitate the identification of patterns of abuse among both authorized and unauthorized users.

#### Rule Record Events that Modify the System's Discretionary Access Controls - umount [ref]
At a minimum, the audit system should collect file system umount changes. If the `auditd` daemon is configured to use the `augenrules` program to read audit rules during daemon startup (the default), add the following line to a file with suffix `.rules` in the directory `/etc/audit/rules.d`:
    -a always,exit -F arch=b32 -S umount -F auid>=1000 -F auid!=unset -F key=perm_mod
If the `auditd` daemon is configured to use the `auditctl` utility to read audit rules during daemon startup, add the following line to `/etc/audit/audit.rules` file:
    -a always,exit -F arch=b32 -S umount -F auid>=1000 -F auid!=unset -F key=perm_mod
Warning: Note that these rules can be configured in a number of ways while still achieving the desired effect. Here the system calls have been placed independent of other system calls. Grouping these system calls with others as identifying earlier in this guide is more efficient.
Rationale: | The changing of file permissions could indicate that a user is attempting to gain access to information that would otherwise be disallowed. Auditing DAC modifications can facilitate the identification of patterns of abuse among both authorized and unauthorized users.

Privileged programs are subject to escalation-of-privilege attacks, which attempt to subvert their normal role of providing some necessary but limited capability. As such, motivation exists to monitor these programs for unusual activity.

#### Rule Record Any Attempts to Run setfiles [ref]
At a minimum, the audit system should collect the execution of privileged commands for all users and root. If the `auditd` daemon is configured to use the `augenrules` program to read audit rules during daemon startup (the default), add a line of the following form to a file with suffix `.rules` in the directory `/etc/audit/rules.d`:
    -a always,exit -F path=/usr/sbin/setfiles -F auid>=1000 -F auid!=unset -F key=privileged
If the `auditd` daemon is configured to use the `auditctl` utility to read audit rules during daemon startup, add a line of the following form to `/etc/audit/audit.rules`:
    -a always,exit -F path=/usr/sbin/setfiles -F auid>=1000 -F auid!=unset -F key=privileged
Rationale: | Misuse of privileged functions, either intentionally or unintentionally by authorized users, or by unauthorized external entities that have compromised system accounts, is a serious and ongoing concern and can have significant adverse impacts on organizations. Auditing the use of privileged functions is one way to detect such misuse and identify the risk from insider and advanced persistent threats. Privileged programs are subject to escalation-of-privilege attacks, which attempt to subvert their normal role of providing some necessary but limited capability. As such, motivation exists to monitor these programs for unusual activity.

    -a always,exit -F arch=ARCH -S init_module,delete_module -F key=modules
Place to add the lines depends on a way `auditd` daemon is configured. If it is configured to use the `augenrules` program (the default), add the lines to a file with suffix `.rules` in the directory `/etc/audit/rules.d`. If the `auditd` daemon is configured to use the `auditctl` utility, add the lines to file `/etc/audit/audit.rules`.

Rationale: | The removal of kernel modules can be used to alter the behavior of the kernel and potentially introduce malicious code into kernel space. It is important to have an audit trail of modules that have been introduced into the kernel.

#### Rule Ensure auditd Collects Information on Kernel Module Loading and Unloading - finit_module [ref]
To capture kernel module loading and unloading events, use the following line, setting ARCH to either b32 for 32-bit system, or having two lines for both b32 and b64 in case your system is 64-bit:
    -a always,exit -F arch=ARCH -S finit_module -F key=modules
Place to add the line depends on a way `auditd` daemon is configured. If it is configured to use the `augenrules` program (the default), add the line to a file with suffix `.rules` in the directory `/etc/audit/rules.d`. If the `auditd` daemon is configured to use the `auditctl` utility, add the line to file `/etc/audit/audit.rules`.
Rationale: | The addition/removal of kernel modules can be used to alter the behavior of the kernel and potentially introduce malicious code into kernel space. It is important to have an audit trail of modules that have been introduced into the kernel.

#### Rule Record Attempts to Alter Logon and Logout Events - tallylog [ref]
The audit system already collects login information for all users and root. If the `auditd` daemon is configured to use the `augenrules` program to read audit rules during daemon startup (the default), add the following lines to a file with suffix `.rules` in the directory `/etc/audit/rules.d`:
    -w /var/log/tallylog -p wa -k logins
If the `auditd` daemon is configured to use the `auditctl` utility to read audit rules during daemon startup, add the following lines to `/etc/audit/audit.rules`:
    -w /var/log/tallylog -p wa -k logins
Rationale: | Manual editing of these files may indicate nefarious activity, such as an attacker attempting to remove evidence of an intrusion.

Group Record Information on the Use of Privileged Commands Group contains 35 rules

#### Rule Ensure auditd Collects Information on the Use of Privileged Commands - chage [ref]
At a minimum, the audit system should collect the execution of privileged commands for all users and root. If the `auditd` daemon is configured to use the `augenrules` program to read audit rules during daemon startup (the default), add a line of the following form to a file with suffix `.rules` in the directory `/etc/audit/rules.d`:
    -a always,exit -F path=/usr/bin/chage -F auid>=1000 -F auid!=unset -F key=privileged
If the `auditd` daemon is configured to use the `auditctl` utility to read audit rules during daemon startup, add a line of the following form to `/etc/audit/audit.rules`:
    -a always,exit -F path=/usr/bin/chage -F auid>=1000 -F auid!=unset -F key=privileged
Rationale: | Misuse of privileged functions, either intentionally or unintentionally by authorized users, or by unauthorized external entities that have compromised system accounts, is a serious and ongoing concern and can have significant adverse impacts on organizations. Auditing the use of privileged functions is one way to detect such misuse and identify the risk from insider and advanced persistent threats. Privileged programs are subject to escalation-of-privilege attacks, which attempt to subvert their normal role of providing some necessary but limited capability. As such, motivation exists to monitor these programs for unusual activity.

#### Rule Ensure auditd Collects Information on the Use of Privileged Commands - fusermount3 [ref]
At a minimum, the audit system should collect the execution of privileged commands for all users and root. If the `auditd` daemon is configured to use the `augenrules` program to read audit rules during daemon startup (the default), add a line of the following form to a file with suffix `.rules` in the directory `/etc/audit/rules.d`:
    -a always,exit -F path=/usr/bin/fusermount3 -F auid>=1000 -F auid!=unset -F key=privileged
If the `auditd` daemon is configured to use the `auditctl` utility to read audit rules during daemon startup, add a line of the following form to `/etc/audit/audit.rules`:
    -a always,exit -F path=/usr/bin/fusermount3 -F auid>=1000 -F auid!=unset -F key=privileged
Rationale: | Misuse of privileged functions, either intentionally or unintentionally by authorized users, or by unauthorized external entities that have compromised system accounts, is a serious and ongoing concern and can have significant adverse impacts on organizations. Auditing the use of privileged functions is one way to detect such misuse and identify the risk from insider and advanced persistent threats. Privileged programs are subject to escalation-of-privilege attacks, which attempt to subvert their normal role of providing some necessary but limited capability. As such, motivation exists to monitor these programs for unusual activity.

Rationale: | Without generating audit records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. Audit records can be generated from various components within the information system (e.g., module or policy filter).

#### Rule Record Any Attempts to Run ssh-agent [ref]
At a minimum, the audit system should collect the execution of privileged commands for all users and root. If the `auditd` daemon is configured to use the `augenrules` program to read audit rules during daemon startup (the default), add a line of the following form to a file with suffix `.rules` in the directory `/etc/audit/rules.d`:
    -a always,exit -F path=/usr/bin/ssh-agent -F auid>=1000 -F auid!=unset -F key=privileged
If the `auditd` daemon is configured to use the `auditctl` utility to read audit rules during daemon startup, add a line of the following form to `/etc/audit/audit.rules`:
    -a always,exit -F path=/usr/bin/ssh-agent -F auid>=1000 -F auid!=unset -F key=privileged
Rationale: | Without generating audit records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. Audit records can be generated from various components within the information system (e.g., module or policy filter).

#### Rule Ensure auditd Collects Information on the Use of Privileged Commands - sudo [ref]
At a minimum, the audit system should collect the execution of privileged commands for all users and root. If the `auditd` daemon is configured to use the `augenrules` program to read audit rules during daemon startup (the default), add a line of the following form to a file with suffix `.rules` in the directory `/etc/audit/rules.d`:
    -a always,exit -F path=/usr/bin/sudo -F auid>=1000 -F auid!=unset -F key=privileged
If the `auditd` daemon is configured to use the `auditctl` utility to read audit rules during daemon startup, add a line of the following form to `/etc/audit/audit.rules`:
    -a always,exit -F path=/usr/bin/sudo -F auid>=1000 -F auid!=unset -F key=privileged
Rationale: | Misuse of privileged functions, either intentionally or unintentionally by authorized users, or by unauthorized external entities that have compromised system accounts, is a serious and ongoing concern and can have significant adverse impacts on organizations. Auditing the use of privileged functions is one way to detect such misuse and identify the risk from insider and advanced persistent threats. Privileged programs are subject to escalation-of-privilege attacks, which attempt to subvert their normal role of providing some necessary but limited capability. As such, motivation exists to monitor these programs for unusual activity.

At a minimum, the audit system should collect the execution of privileged commands for all users and root. If the `auditd` daemon is configured to use the `augenrules` program to read audit rules during daemon startup (the default), add a line of the following form to a file with suffix `.rules` in the directory `/etc/audit/rules.d`:
    -a always,exit -F path=/usr/sbin/userhelper -F auid>=1000 -F auid!=unset -F key=privileged
If the `auditd` daemon is configured to use the `auditctl` utility to read audit rules during daemon startup, add a line of the following form to `/etc/audit/audit.rules`:
    -a always,exit -F path=/usr/sbin/userhelper -F auid>=1000 -F auid!=unset -F key=privileged
Rationale: | Misuse of privileged functions, either intentionally or unintentionally by authorized users, or by unauthorized external entities that have compromised system accounts, is a serious and ongoing concern and can have significant adverse impacts on organizations. Auditing the use of privileged functions is one way to detect such misuse and identify the risk from insider and advanced persistent threats. Privileged programs are subject to escalation-of-privilege attacks, which attempt to subvert their normal role of providing some necessary but limited capability. As such, motivation exists to monitor these programs for unusual activity.

#### Rule Make the auditd Configuration Immutable [ref]
If the `auditd` daemon is configured to use the `augenrules` program to read audit rules during daemon startup (the default), add the following line to a file with suffix `.rules` in the directory `/etc/audit/rules.d` in order to make the auditd configuration immutable:

If the `auditd` daemon is configured to use the `auditctl` utility to read audit rules during daemon startup, add the following line to `/etc/audit/audit.rules` file in order to make the auditd configuration immutable:
    -e 2
With this setting, a reboot will be required to change any audit rules.
Rationale: | Making the audit configuration immutable prevents accidental as well as malicious modification of the audit rules, although it may be problematic if legitimate changes are needed during system operation.

#### Rule Ensure auditd Collects System Administrator Actions - /etc/sudoers [ref]
At a minimum, the audit system should collect administrator actions for all users and root. If the `auditd` daemon is configured to use the `augenrules` program to read audit rules during daemon startup (the default), add the following lines to a file with suffix `.rules` in the directory `/etc/audit/rules.d`:
    -w /etc/sudoers -p wa -k actions
If the `auditd` daemon is configured to use the `auditctl` utility to read audit rules during daemon startup, add the following lines to `/etc/audit/audit.rules`:
    -w /etc/sudoers -p wa -k actions
Rationale: | The actions taken by system administrators should be audited to keep a record of what was executed on the system, as well as, for accountability purposes. Editing the sudoers file may be sign of an attacker trying to establish persistent methods to a system, auditing the editing of the sudoers files mitigates this risk.

#### Rule Record Events When Privileged Executables Are Run [ref]
Verify the system generates an audit record when privileged functions are executed. If audit is using the "auditctl" tool to load the rules, run the following command:
    $ sudo grep execve /etc/audit/audit.rules
If audit is using the "augenrules" tool to load the rules, run the following command:
    $ sudo grep -r execve /etc/audit/rules.d
    -a always,exit -F arch=b32 -S execve -C uid!=euid -F euid=0 -k setuid
    -a always,exit -F arch=b64 -S execve -C uid!=euid -F euid=0 -k setuid
    -a always,exit -F arch=b32 -S execve -C gid!=egid -F egid=0 -k setgid
    -a always,exit -F arch=b64 -S execve -C gid!=egid -F egid=0 -k setgid
If both the "b32" and "b64" audit rules for "SUID" files are not defined, this is a finding. If both the "b32" and "b64" audit rules for "SGID" files are not defined, this is a finding. Warning: Note that these rules can be configured in a number of ways while still achieving the desired effect.
Rationale: | Misuse of privileged functions, either intentionally or unintentionally by authorized users, or by unauthorized external entities that have compromised information system accounts, is a serious and ongoing concern and can have significant adverse impacts on organizations. Auditing the use of privileged functions is one way to detect such misuse and identify the risk from insider threats and the advanced persistent threat.

#### Rule Record Events that Modify User/Group Information - /etc/shadow [ref]
If the `auditd` daemon is configured to use the `augenrules` program to read audit rules during daemon startup (the default), add the following lines to a file with suffix `.rules` in the directory `/etc/audit/rules.d`:
    -w /etc/shadow -p wa -k audit_rules_usergroup_modification
If the `auditd` daemon is configured to use the `auditctl` utility to read audit rules during daemon startup, add the following lines to `/etc/audit/audit.rules`:
    -w /etc/shadow -p wa -k audit_rules_usergroup_modification
Rationale: | In addition to auditing new user and group accounts, these watches will alert the system administrator(s) to any modifications. Any unexpected users, groups, or modifications should be investigated for legitimacy.

#### Rule System Audit Logs Must Have Mode 0640 or Less Permissive [ref]
Verify the audit log files have a mode of "0640" or less permissive by first determining where the audit logs are stored with the following command:
    $ sudo grep -iw log_file /etc/audit/auditd.conf
    log_file = /var/log/audit/audit.log
By default, the audit log file is `/var/log/audit/audit.log`. Configure the audit log to be protected from unauthorized read access by setting the correct permissive mode. If `log_group` in `/etc/audit/auditd.conf` is set to a group other than the `root` group account, change the mode of the audit log files with the following command:
    $ sudo chmod 0640 audit_log_file
Otherwise, change the mode of the audit log files with the following command:
    $ sudo chmod 0600 audit_log_file
Replace `audit_log_file` with the correct audit log file path.
Rationale: | If users can write to audit logs, audit trails can be modified or destroyed.

Group Configure auditd Data Retention Group contains 3 rules
[ref] The audit system writes data to `/var/log/audit/audit.log`. By default, `auditd` rotates 5 logs by size (6MB), retaining a maximum of 30MB of data in total, and refuses to write entries when the disk is too full. This minimizes the risk of audit data filling its partition and impacting other services. This also minimizes the risk of the audit daemon temporarily disabling the system if it cannot write audit log (which it can be configured to do). For a busy system or a system which is thoroughly auditing system activity, the default settings for data retention may be insufficient. The log file size needed will depend heavily on what types of events are being audited. First configure auditing to log all the events of interest. Then monitor the log size manually for awhile to determine what file size will allow you to keep the required data for the correct time period. Using a dedicated partition for `/var/log/audit` prevents the `auditd` logs from disrupting system functionality if they fill, and, more importantly, prevents other activity in `/var` from filling the partition and stopping the audit trail. (The audit logs are size-limited and therefore unlikely to grow without bound unless configured to do so.) Some machines may have requirements that no actions occur which cannot be audited. If this is the case, then `auditd` can be configured to halt the machine if it runs out of space. Note: Since older logs are rotated, configuring `auditd` this way does not prevent older logs from being rotated away before they can be viewed. If your system is configured to halt when logging cannot be performed, make sure this can never happen under normal circumstances! Ensure that `/var/log/audit` is on its own partition, and that this partition is larger than the maximum amount of data `auditd` will retain normally.
#### Rule Configure auditd Disk Error Action on Disk Error [ref]
The `auditd` service can be configured to take an action when there is a disk error. Edit the file `/etc/audit/auditd.conf`. Add or modify the following line, substituting ACTION appropriately:
    disk_error_action = ACTION
Set this value to `single` to cause the system to switch to single-user mode for corrective action. Acceptable values also include `syslog`, `exec`, `single`, and `halt` For certain systems, the need for availability outweighs the need to log all actions, and a different setting should be determined. Details regarding all possible values for ACTION are described in the `auditd.conf` man page.
Rationale: | Taking appropriate action in case of disk errors will minimize the possibility of losing audit records.

#### Rule Configure auditd max_log_file_action Upon Reaching Maximum Log Size [ref]
The default action to take when the logs reach their maximum size is to rotate the log files, discarding the oldest one. To configure the action taken by `auditd`, add or correct the line in `/etc/audit/auditd.conf`:
    max_log_file_action = ACTION
Possible values for ACTION are described in the `auditd.conf` man page. These include: `ignore` `syslog` `suspend` `rotate` `keep_logs` Set the `ACTION` to `rotate` to ensure log rotation occurs. This is the default. The setting is case-insensitive.
Rationale: | Automatically rotating logs (by setting this to `rotate`) minimizes the chances of the system unexpectedly running out of disk space by being overwhelmed with log data. However, for systems that must never discard log data, or which use external processes to transfer it and reclaim space, `keep_logs` can be employed.

#### Rule Resolve information before writing to audit logs [ref]
To configure Audit daemon to resolve all uid, gid, syscall, architecture, and socket address information before writing the events to disk, set `log_format` to `ENRICHED` in `/etc/audit/auditd.conf`.
Rationale: | If option `log_format` isn't set to `ENRICHED`, the audit records will be stored in a format exactly as the kernel sends them.

    ## Unsuccessful file delete
    -a always,exit -F arch=b32 -S unlink,unlinkat,rename,renameat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccessful-delete

    -a always,exit -F arch=b64 -S unlink,unlinkat,rename,renameat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccessful-delete
Load new Audit rules into kernel by running:
    augenrules --load
Note: This rule uses a special set of Audit rules to comply with OSPP 4.2.1. You may reuse this rule in different profiles. If you decide to do so, it is recommended that you inspect contents of the file closely and make sure that they are aligned with your needs.
Rationale: | Unsuccessful attempts to delete a file might be signs of malicious activities. Auditing of such events help in monitoring and investigating of such activities.

#### Rule Configure immutable Audit login UIDs [ref]
Configure kernel to prevent modification of login UIDs once they are set. Changing login UIDs while this configuration is enforced requires special capabilities which are not available to unprivileged users. The following rules configure audit as described above:
    ## Make the loginuid immutable. This prevents tampering with the auid.
    --loginuid-immutable
Load new Audit rules into kernel by running:
    augenrules --load
Rationale: | If modification of login UIDs is not prevented, they can be changed by unprivileged users and make auditing complicated or impossible.

#### Rule Enable auditd Service [ref]
The `auditd` service is an essential userspace component of the Linux Auditing System, as it is responsible for writing audit records to disk. The `auditd` service can be enabled with the following manifest:
    ---
    apiVersion: machineconfiguration.openshift.io/v1
    kind: MachineConfig
    metadata:
      labels:
        machineconfiguration.openshift.io/role: master
      name: 75-master-auditd-enable
    spec:
      config:
        ignition:
          version: 3.1.0
        systemd:
          units:
          - name: auditd.service
            enabled: true
This will enable the `auditd` service in all the nodes labeled with the "master" role. Note that this needs to be done for each `MachineConfigPool` For more information on how to configure nodes with the Machine Config Operator see the relevant documentation.
Rationale: | Without establishing what type of events occurred, it would be difficult to establish, correlate, and investigate the events leading up to an outage or attack. Ensuring the `auditd` service is active ensures audit records generated by the kernel are appropriately recorded. Additionally, a properly configured audit subsystem ensures that actions of individual system users can be uniquely traced to those users so they can be held accountable for their actions.

#### Rule Extend Audit Backlog Limit for the Audit Daemon [ref]
To improve the kernel capacity to queue all log events, even those which occurred prior to the audit daemon, add the argument `audit_backlog_limit=8192` to all BLS (Boot Loader Specification) entries ('options' line) for the Linux operating system in `/boot/loader/entries/*.conf`.
Rationale: | audit_backlog_limit sets the queue length for audit events awaiting transfer to the audit daemon. Until the audit daemon is up and running, all log messages are stored in this queue. If the queue is overrun during boot process, the action defined by audit failure flag is taken.

#### Rule Enable Auditing for Processes Which Start Prior to the Audit Daemon [ref]
To ensure all processes can be audited, even those which start prior to the audit daemon, add the argument `audit=1` to all BLS (Boot Loader Specification) entries ('options' line) for the Linux operating system in `/boot/loader/entries/*.conf`.
Rationale: | Each process on the system carries an "auditable" flag which indicates whether its activities can be audited. Although `auditd` takes care of enabling this for all processes which launch after it does, adding the kernel argument ensures it is set for every process during boot.
