auditd – audit log management daemon



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 [em] 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.


/var/audit 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.


This software was created by McAfee Research, the security research division of McAfee, Inc., under contract to Apple Computer Inc. Additional authors include Wayne Salamon, Robert Watson, and SPARTA Inc.

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

On two occasions I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.
