Check: AOSX-09-002125
Apple OS X 10.9 Workstation STIG:
AOSX-09-002125
(in version v1 r2)
Title
The operating system must generate audit records when successful/unsuccessful attempts to modify privileges occur. (Cat II impact)
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 in order to proceed. Auditing successful and unsuccessful attempts to switch to another user account mitigates this risk.
Check Content
In order to view the currently configured flags for the audit daemon, run the following command: sudo grep ^flags /etc/security/audit_control Attempts to log in as another user are logged by way of the 'lo' flag. If 'lo' is not listed in the result of the check, this is a finding.
Fix Text
To make sure the appropriate flags are enabled for auditing, run the following command: sudo sed -i.bak '/^flags/ s/$/,lo/' /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.
