| 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-75711r1091693_chk) |
| Verify that OL 9 is configured to mount /var/log/audit with the noexec option. Verify "/var/log/audit" is mounted with the "noexec" option: $ mount | grep /var/log/audit /dev/mapper/ol-var-log-audit 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-75618r1091694_fix) |
| Configure OL 9 to mount /var/log/audit with the noexec option. Modify "/etc/fstab" to use the "noexec" option on the "/var/log/audit" directory. |
