APPL-13-001044 - The macOS 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.

Information

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).

Logon events are logged by way of the 'aa' flag.

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

Solution

Configure the macOS system to audit logon events with 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.
