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).

Check Text ( C-21023r305222_chk )
Verify if the Ubuntu operating system is configured to audit the execution of the module management program "modprobe", by running the following command: sudo auditctl -l \| grep "/sbin/modprobe" -w /sbin/modprobe -p x -k modules If the command does not return a line, 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.
