| Check Text (C-52252r780018_chk) |
| Verify OL 8 takes action when allocated audit record storage volume reaches 75 percent of the repository maximum audit record storage capacity with the following commands: $ sudo grep -w space_left /etc/audit/auditd.conf space_left = 25% If the value of the "space_left" keyword is not set to "25%" or if the line is commented out, ask the SA to demonstrate how the system is providing real-time alerts to the SA and ISSO. If there is no evidence that real-time alerts are configured on the system, this is a finding. |
