The Photon operating system must alert the ISSO and SA in the event of an audit processing failure.

It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without this notification, the security personnel may be unaware of an impending failure of the audit capability, and system operation may be adversely affected.

Audit processing failures include software/hardware errors, failures in the audit capturing mechanisms, and audit storage capacity being reached or exceeded.

At the command line, run the following command to verify auditd is configured to send an alert via syslog in the event of an audit processing failure:

# grep -E "^disk_full_action|^disk_error_action|^admin_space_left_action" /etc/audit/auditd.conf

Example result:

admin_space_left_action = SYSLOG disk_full_action = SYSLOG disk_error_action = SYSLOG

If "disk_full_action", "disk_error_action", and "admin_space_left_action" are not set to SYSLOG or are missing, this is a finding.

Navigate to and open:

/etc/audit/auditd.conf

Ensure the following lines are present, not duplicated, and not commented:

disk_full_action = SYSLOG disk_error_action = SYSLOG admin_space_left_action = SYSLOG

At the command line, run the following command:

# pkill -SIGHUP auditd
