Title

The operating system must generate audit records when successful/unsuccessful logon attempts occur. (Cat II impact)

Discussion

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).

Check Content

Verify the operating system generates audit records when successful/unsuccessful logon attempts occur. If it does not, this is a finding. To check if auditing is in place: $ grep auditd /etc/rc.conf A line indicating auditing is enabled should be returned. Check that user audits occur: $ cat /etc/security/audit_class This file provides a description of the various audit event short names (i.e., "lo" is "login_logout" by default). $ cat /etc/security/audit_control Ensure "flags" and "naflags" both contain "lo". $ cat /etc/security/audit_user Ensure loging/logout is not overriden for certain users.

Fix Text

Configure the operating system to generate audit records when successful/unsuccessful logon attempts occur.
