AUDIT_CLASS(5) BSD File Formats Manual AUDIT_CLASS(5)NAME
audit_class -- audit event class descriptions
DESCRIPTION
The audit_class file contains descriptions of the auditable event classes on the system. Each auditable event is a member of an event class.
Each line maps an audit event mask (bitmap) to a class and a description. Entries are of the form:
classmask:eventclass:description
Example entries in this file are:
0x00000000:no:invalid class
0x00000001:fr:file read
0x00000002:fw:file write
0x00000004:fa:file attribute access
0x00000080:pc:process
0x10000000:res:reserved for internal use
0xffffffff:all:all flags set
NOTES
The audit class res is reserved for internal use. Unentitled applications can still modify the event class preselection mask for an audit
event (for example by using the audit_event(5) configuration file or the auditon(2) system call with the A_SETCLASS command), however these
applications will not be able to change the res audit class mask for that event.

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 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 surprising if not expected.
