AUDIT_USER(5)		  FreeBSD File Formats Manual		 AUDIT_USER(5)

NAME
     audit_user	-- events to be	audited	for given users

DESCRIPTION
     The audit_user file specifies which audit event classes are to be audited
     for the given users.  If specified, these flags are combined with the
     system-wide audit flags in	the audit_control(5) file to determine which
     classes of	events to audit	for that user.	These settings take effect
     when the user logs	in.

     Each line maps a user name	to a list of classes that should be audited
     and a list	of classes that	should not be audited.	Entries	are of the
     form:

	   username:alwaysaudit:neveraudit

     In	the format above, alwaysaudit is a set of event	classes	that are
     always audited, and neveraudit is a set of	event classes that should not
     be	audited.  These	sets can indicate the inclusion	or exclusion of	multi-
     ple classes, and whether to audit successful or failed events.  See
     audit_control(5) for more information about audit flags.

     Example entries in	this file are:

	   root:lo,ad:no
	   jdoe:-fc,ad:+fw

     These settings would cause	login/logout and administrative	events that
     are performed on behalf of	user ``root'' to be audited.  No failure
     events are	audited.  For the user ``jdoe'', failed	file creation events
     are audited, administrative events	are audited, and successful file write
     events are	never audited.

IMPLEMENTATION NOTES
     Per-user and global audit preselection configuration are evaluated	at
     time of login, so users must log out and back in again for	audit changes
     relating to preselection to take effect.

     Audit record preselection occurs with respect to the audit	identifier
     associated	with a process,	rather than with respect to the	UNIX user or
     group ID.	The audit identifier is	set as part of the user	credential
     context as	part of	login, and typically does not change as	a result of
     running setuid or setgid applications, such as su(1).  This has the
     advantage that events that	occur after running su(1) can be audited to
     the original authenticated	user, as required by CAPP, but may be surpris-
     ing if not	expected.

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.

AUTHORS
     This software was created by McAfee Research, the security	research divi-
     sion 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.
