contrib/openbsm (svn merge) and src/sys/{bsm,security/audit} (manual
merge). Hook up bsm_domain.c and bsm_socket_type.c to the libbsm
build along with man pages, add audit_bsm_domain.c and
audit_bsm_socket_type.c to the kernel environment.

OpenBSM 1.1 alpha 5
- Stub libauditd(3) man page added.
- All BSM error number constants with BSM_ERRNO_.
- Interfaces to convert between local and BSM socket types and protocol
families have been added: au_bsm_to_domain(3), au_bsm_to_socket_type(3),
au_domain_to_bsm(3), and au_socket_type_to_bsm(3), along with definitions
of constants in audit_domain.h and audit_socket_type.h. This improves
interoperability by converting local constant spaces, which vary by OS, to
and from Solaris constants (where available) or OpenBSM constants for
protocol domains not present in Solaris (a fair number). These routines
should be used when generating and interpreting extended socket tokens.
- Fix build warnings with full gcc warnings enabled on most supported
platforms.
- Don't compile error strings into bsm_errno.c when building it in the kernel
environment.
- When started by launchd, use the label com.apple.auditd rather than
org.trustedbsd.auditd.

.Dt AUDIT_USER 5
|
|
.Os
|
|
.Sh NAME
|
|
.Nm audit_user
|
|
.Nd "events to be audited for given users"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
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
|
|
.Xr audit_control 5
|
|
file to determine which classes of events to audit for that user.
|
|
These settings take effect when the user logs in.
|
|
.Pp
|
|
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:
|
|
.Pp
|
|
.D1 Ar username Ns : Ns Ar alwaysaudit Ns : Ns Ar neveraudit
|
|
.Pp
|
|
In the format above,
|
|
.Ar alwaysaudit
|
|
is a set of event classes that are always audited, and
|
|
.Ar 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
|
|
.Xr audit_control 5
|
|
for more information about audit flags.
|
|
.Pp
|
|
Example entries in this file are:
|
|
.Bd -literal -offset indent
|
|
root:lo,ad:no
|
|
jdoe:-fc,ad:+fw
|
|
.Ed
|
|
.Pp
|
|
These settings would cause login/logout and administrative events that
|
|
are performed on behalf of user
|
|
.Dq Li root
|
|
to be audited.
|
|
No failure events are audited.
|
|
For the user
|
|
.Dq Li jdoe ,
|
|
failed file creation events are audited, administrative events are
|
|
audited, and successful file write events are never audited.
|
|
.Sh 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.
|
|
.Pp
|
|
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
|
|
.Xr su 1 .
|
|
This has the advantage that events that occur after running
|
|
.Xr su 1
|
|
can be audited to the original authenticated user, as required by CAPP, but
|
|
may be surprising if not expected.

|
|
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.
