| Description | ||||
| The "noexec" mount option causes the system to not execute binary files. This option must be used for mounting any file system not containing approved binary files, as they may be incompatible. Executing files from untrusted file systems increases the opportunity for nonprivileged users to attain unauthorized administrative access. | ||||

Check Text (C-281092r1165631_chk)
Verify RHEL 10 is configured so that "/var/log/audit" is mounted with the "noexec" option:
$ mount | grep /var/log/audit
/dev/mapper/luks-4e45e1ad-5337-42c4-a19f-ee12ccc1d502 on /var/log/audit type xfs (rw,nodev,nosuid,noexec,seclabel)
If the "/var/log/audit" file system is mounted without the "noexec" option, this is a finding.
Fix Text (F-85558r1165630_fix)
Configure RHEL 10 to mount "/var/log/audit" with the "noexec" option.
Modify "/etc/fstab" to use the "noexec" option on the "/var/log/audit" directory.
