The TOSS 5 audit system must audit local events.

Without establishing what type of events occurred, the source of events, where events occurred, and the outcome of events, it would be difficult to establish, correlate, and investigate the events leading up to an outage or attack.

If option "local_events" isn't set to "yes", only events from network will be aggregated.

Verify the TOSS 5 audit system is configured to audit local events using the following command:

$ sudo grep local_events /etc/audit/auditd.conf 

local_events = yes

If "local_events" is not set to "yes", if the command does not return a line, or the line is commented out, this is a finding.

Configure TOSS 5 to generate audit records for local events by adding or updating the following line in "/etc/audit/auditd.conf":

local_events = yes

Restart the audit daemon for the changes to take effect.
