The operating system must generate audit records for DoD defined events such as: successful/unsuccessful logon attempts, successful/unsuccessful direct access attempts, starting and ending time for user access, and concurrent logons to the same account from different sources.

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). Satisfies: SRG-OS-000470-GPOS-00214, SRG-OS-000472-GPOS-00217, SRG-OS-000473-GPOS-00218, SRG-OS-000475-GPOS-00220

Check Text ( C-68119r2_chk )
In order to view the currently configured flags for the audit daemon, run the following command: /usr/bin/sudo /usr/bin/grep ^flags /etc/security/audit_control Logon events are logged by way of the "aa" flag. If "aa" is not listed in the result of the check, this is a finding.

Fix Text (F-73667r2_fix)
To make sure the appropriate flags are enabled for auditing, run the following command: /usr/bin/sudo /usr/bin/sed -i.bak '/^flags/ s/$/,aa/' /etc/security/audit_control; /usr/bin/sudo /usr/sbin/audit -s A text editor may also be used to implement the required updates to the "/etc/security/audit_control" file.
