Title
The operating system must provide audit record generation capability for DoD-defined auditable events for all operating system components. (Cat II impact)
Discussion
Without the capability to generate audit records, it would be difficult to establish, correlate, and investigate the events relating to an incident, or identify those responsible for one. DoD has defined the list of events for which the operating system will provide an audit record generation capability as the following: (i) Successful and unsuccessful attempts to access, modify, or delete privileges, security objects, security levels, or categories of information (e.g., classification levels); (ii) Access actions, such as successful and unsuccessful logon attempts, privileged activities or other system level access, starting and ending time for user access to the system, concurrent logons from different workstations, successful and unsuccessful accesses to objects, all program initiations, and all direct access to the information system; (iii) All account creations, modifications, disabling, and terminations; and (iv) All kernel module load, unload, and restart actions.
Check Content
The options to configure the audit daemon are located in the /etc/security/audit_control file. To view the current settings, run the following command: sudo grep ^flags /etc/security/audit_control If the 'lo', 'ad', and 'aa' options are not set, this is a finding.
Fix Text
To set the audit flags to the recommended setting, run the following command to add the flags 'lo', 'ad', and 'aa' all at once: sudo sed -i.bak '/^flags/ s/$/,lo,ad,aa/' /etc/security/audit_control; sudo audit -s A text editor may also be used to implement the required update to the /etc/security/audit_control file.
