OL 8 must resolve audit information before writing to disk.

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

Audit record content that may be necessary to satisfy this requirement includes, for example, time stamps, source and destination addresses, user/process identifiers, event descriptions, success/fail indications, filenames involved, and access control or flow control rules invoked.

Enriched logging aids in making sense of who, what, and when events occur on a system. Without this, determining root cause of an event will be much more difficult.

Verify the OL 8 audit daemon is configured to resolve audit information before writing to disk, with the following command:

$ sudo grep "log_format" /etc/audit/auditd.conf 

log_format = ENRICHED

If the "log_format" option is not "ENRICHED", or the line is commented out, this is a finding.

Configure OL 8 to resolve audit information before writing to disk by adding the following line to the "/etc/audit/auditd.conf" file and add or update the "log_format" option:

log_format = ENRICHED

The audit daemon must be restarted for changes to take effect.
