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
     multiple 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 cre-dential credential
     dential 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 surprising 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.
