AUDIT_USER(5)		    BSD 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

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