The noexec mount option specifies that the filesystem cannot contain executable binaries.
Rationale:
Since the /var/log/audit filesystem is only intended for audit logs, set this option to ensure that users cannot run executable binaries from /var/log/audit.
Fix:
Run the following command to remount /var/log/audit:
# mount -o remount,noexec /var/log/audit
Also add or edit entry for /var/log/audit in /etc/fstab as appropriate.
Parameter:
[yes/no]
Technical Mechanism:
Run the following command to remount /var/log/audit:
# mount -o remount,noexec /var/log/audit
