30.Sh NAME
31.Nm audit
32.Nd Security Event Audit
33.Sh SYNOPSIS
--- 68 unchanged lines hidden (view full) ---
102.An Robert Watson Aq rwatson@FreeBSD.org .
103.Sh HISTORY
104The OpenBSM implementation was created by McAfee Research, the security
105division of McAfee Inc., under contract to Apple Computer Inc. in 2004.
106It was subsequently adopted by the TrustedBSD Project as the foundation for
107the OpenBSM distribution.
108.Pp
109Support for kernel audit first appeared in
110.Fx 6.2 .
111.Sh BUGS
112The audit facility in
113.Fx
114is considered experimental, and production deployment should occur only after
115careful consideration of the risks of deploying experimental software.
116.Pp
117The
118.Fx
119kernel does not fully validate that audit records submitted by user
120applications are syntactically valid BSM; as submission of records is limited
121to privileged processes, this is not a critical bug.
122.Pp
123Instrumentation of auditable events in the kernel is not complete, as some
124system calls do not generate audit records, or generate audit records with
125incomplete argument information.
126.Pp
127Mandatory Access Control (MAC) labels, as provided by the
128.Xr mac 4
129facility, are not audited as part of records involving MAC decisions.
