Title

The audit system must be configured to audit login, logout, and session initiation. (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 lo /etc/security/audit_control If the lo flag is not set, and both the +lo and -lo flags are not set, this is a finding. If the lo naflag is not set, and both the +lo and -lo naflags are not set, this is a finding.

Fix Text

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