Description
Without generating audit records that are 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).

Verify the Ubuntu operating system audits privileged activities. Check the currently configured audit rules with the following command: # sudo auditctl -l \| grep sudo.log -w /var/log/sudo.log -p wa -k priv_actions If the command does not return lines that match the example or the lines are commented out, this is a finding. Notes: The '-k' allows for specifying an arbitrary identifier and the string after it does not need to match the example output above.
