Title

The audit system must be configured to audit failed attempts to access files and programs. (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 audit configuration to determine if failed attempts to access files and programs are audited. # more /etc/security/audit_control If flags -fr or fr are not configured, this is a finding.

Fix Text

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