AUDITD(8) System Manager's Manual AUDITD(8)

auditdaudit log management daemon

The audit(4) subsystem has been deprecated since macOS 11.0, disabled since macOS 14.0, and WILL BE REMOVED in a future version of macOS. Applications that require a security event stream should use the EndpointSecurity(7) API instead.

On this version of macOS, you can re-enable audit(4) by renaming or copying /etc/security/audit_control.example to /etc/security/audit_control, re-enabling the system/ service by running launchctl enable system/ as root, and rebooting.

auditd [-d | -l]

The auditd daemon responds to requests from the audit(8) utility and notifications from the kernel. It manages the resulting audit log files and specified log file locations.

The options are as follows:

Starts the daemon in debug mode — it will not daemonize.
This option is for when auditd is configured to start on-demand using launchd(8).

Optionally, the audit review group "audit" may be created. Non-privileged users that are members of this group may read the audit trail log files.

To assure uninterrupted audit support, the auditd daemon should not be started and stopped manually. Instead, the audit(8) command should be used to inform the daemon to change state/configuration after altering the audit_control file.

If auditd is started on-demand by launchd(8) then auditing should only be started and stopped with audit(8).

On Mac OS X, auditd uses the asl(3) API for writing system log messages. Therefore, only the audit administrator and members of the audit review group will be able to read the system log entries.

Default directory for storing audit log files.

The directory containing the auditing configuration files audit_class(5), audit_control(5), audit_event(5), and audit_warn(5).

The historical -h and -s flags are now configured using audit_control(5) policy flags ahlt and cnt, and are no longer available as arguments to auditd.

The OpenBSM implementation was created by McAfee Research, the security division of McAfee Inc., under contract to Apple Computer Inc. in 2004. It was subsequently adopted by the TrustedBSD Project as the foundation for the OpenBSM distribution.

The Basic Security Module (BSM) interface to audit records and audit event stream format were defined by Sun Microsystems.
