Fix Recommendation

Configure the operating system to immediately notify the SA and ISSO (at a minimum) when the threshold for the repository maximum audit record storage capacity is reached.

Uncomment or edit the "space_left_action" keyword in "/etc/audit/auditd.conf" and set it to "email".

space_left_action = email

Check Contents

Verify the operating system immediately notifies the SA and ISSO (at a minimum) via email when the allocated audit record storage volume reaches 75 percent of the repository maximum audit record storage capacity.

Check what action the operating system takes when the threshold for the repository maximum audit record storage capacity is reached with the following command:

# grep -i space_left_action /etc/audit/auditd.conf
space_left_action = email

If the value of the "space_left_action" keyword is not set to "email", this is a finding.
