Title

The operating system must generate audit records for privileged activities or other system-level access. (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). Satisfies: SRG-OS-000471-GPOS-00215

Check Content

Verify the operating system generates audit records for privileged activities or other system-level access. 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 which audits occur: $ cat /etc/security/audit_class $ cat /etc/security/audit_event These two files document the types of audit events available. $ cat /etc/security/audit_control $ cat /etc/security/audit_user These two document what is actually audited by default (audit_control) and per-user (audit_user). If "ad" or "aa" are not audited, this is a finding. The FreeBSD "audit_*" (5) manpages document each file's format. For example, see "man 5 audit_user" and "man 5 audit_control" for details on the user and control auditing files.
