The Photon operating system must ensure audit events are flushed to disk at proper intervals.

Without the capability to generate audit records, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. To that end, the auditd service must be configured to start automatically and be running at all times.

At the command line, run the following command to verify auditd is configured to flush audit events to disk regularly:

# grep -E "freq|flush" /etc/audit/auditd.conf

Example result:

flush = INCREMENTAL_ASYNC freq = 50

If "flush" is not set to "INCREMENTAL_ASYNC", this is a finding. If "freq" is not set to "50", this is a finding.

Navigate to and open:

/etc/audit/auditd.conf

Add or update the following lines:

flush = INCREMENTAL_ASYNC freq = 50

At the command line, run the following command:

# pkill -SIGHUP auditd
