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. The term moddac is code for MODify Dicscretionary Access Control (i.e., chown, chmod, etc.). # grep -i audevent_args1 /etc/rc.config.d/auditing | grep moddac If no results are returned, this is a finding.

Fix Text

Edit /etc/rc.config.d/auditing and add -e moddac to the end of the AUDEVENT_ARGS1 parameter.
