Title

The audit system must be configured to audit all discretionary access control permission modifications. (Cat II impact)

Discussion

If the system is not configured to audit certain activities and write them to an audit log, it is more difficult to detect and track system compromises and damages incurred during a system compromise.

Check Content

Check the system's audit configuration. # grep flags /etc/security/audit_control Confirm flags fm or +fm and -fm are configured.

Fix Text

Edit /etc/security/audit_control and add fm to the flags list. Load the new audit configuration. # auditconfig -conf
