| Description |
| Without generating audit records specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. Audit records can be generated from various components within the information system (e.g., module or policy filter). |

| Check Text (C-74844r1066920_chk) |
| Verify Ubuntu 24.04 LTS generates audit records showing start and stop times for user access to the system via the "/var/run/utmp" file with the following command: $ sudo auditctl -l | grep '/var/run/utmp' -w /var/run/utmp -p wa -k logins If the command does not return a line matching the example or the line is commented out, this is a finding. Note: The "-k" allows for specifying an arbitrary identifier, and the string after it does not need to match the example output above. |
