Vuln Discussion

Frequently, an attacker that successfully gains access to a system has only gained access to an account with limited privileges, such as a guest account or a service account. The attacker must attempt to change to another user account with normal or elevated privileges to proceed. 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).

Attempts to log in as another user are logged by way of the "lo" flag.

Check Content

Verify the macOS system is configured to audit attempts to access/modify privileges with the following command:

/usr/bin/sudo /usr/bin/grep ^flags /etc/security/audit_control

If "lo" is not listed in the result of the check, this is a finding.
