.Dt AUDIT 4
|
|
.Sh NAME
|
|
.Nm audit
|
|
.Nd Security Event Audit
|
|
.Sh SYNOPSIS
|
|
.Cd "options AUDIT"
|
|
.Sh DESCRIPTION
|
|
Security Event Audit is a facility to provide fine-grained, configurable
|
|
logging of security-relevant events, and is intended to meet the requirements
|
|
of the Common Criteria (CC) Common Access Protection Profile (CAPP)
|
|
evaluation.
|
|
The
|
|
.Fx
|
|
audit facility implements the de facto industry standard BSM API, file
|
|
formats, and command line interface, first found in the Solaris operating
|
|
system.
|
|
Information on the user space implementation can be found in
|
|
.Xr libbsm 3 .
|
|
.Pp
|
|
Audit support is enabled at boot, if present in the kernel, using an
|
|
.Xr rc.conf 5
|
|
flag.
|
|
The audit daemon,
|
|
.Xr auditd 8 ,
|
|
is responsible for configuring the kernel to perform audit, pushing
|
|
configuration data from the various audit configuration files into the
|
|
kernel.

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

|
|
.Sh HISTORY
|
|
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.
|
|
.Pp
|
|
Support for kernel audit first appeared in
|
|
.Fx 6.1 .
|
|
.Sh BUGS
|
|
The audit facility in
|
|
.Fx
|
|
is considered experimental, and production deployment should occur only after
|
|
careful consideration of the risks of deploying experimental software.
|
|
.Pp
|
|
The
|
|
.Fx
|
|
kernel does not fully validate that audit records submitted by user
|
|
applications are syntactically valid BSM; as submission of records is limited
|
|
to privileged processes, this is not a critical bug.
|
|
.Pp
|
|
Instrumentation of auditable events in the kernel is not complete, as some
|
|
system calls do not generate audit records, or generate audit records with
|
|
incomplete argument information.
|
|
.Pp
|
|
Mandatory Access Control (MAC) labels, as provided by the
|
|
.Xr mac 4
|
|
facility, are not audited as part of records involving MAC decisions.
