LIBBSM(3)              FreeBSD Library Functions Manual              LIBBSM(3)

NAME
     libbsm -- Basic Security Module (BSM) Audit API

LIBRARY
     Basic Security Module User Library (libbsm, -lbsm)

SYNOPSIS
     #include <libbsm.h>

DESCRIPTION
     The libbsm library routines provide an interface to BSM audit record
     streams, allowing both the parsing of existing audit streams, as well as
     the creation of new audit records and streams.

INTERFACES
     libbsm provides a large number of Audit programming interfaces in several
     classes: event stream interfaces, class interfaces, control interfaces,
     event interfaces, I/O interfaces, mask interfaces, notification inter-
     faces, token interfaces, and user interfaces.  These are described
     respectively in the au_class(3), au_control(3), au_event(3), au_mask(3),
     au_notify(3), au_stream(3), au_token(3), and au_user(3) manual pages.

   Audit Event Stream Interfaces
     Audit event stream interfaces support interaction with file-backed audit
     event streams: au_close(3), au_close_buffer(3), au_free_token(3),
     au_open(3), au_write(3), audit_submit(3).

   Audit Class Interfaces
     Audit class interfaces support the look up of information from the
     audit_class(5) database: endauclass(3), getauclassent(3),
     getauclassent_r(3), getauclassnam(3), getauclassnam_r(3), setauclass(3).

   Audit Control Interfaces
     Audit control interfaces support the look up of information from the
     audit_control(5) database: endac(3), setac(3), getacdir(3),
     getacfilesz(3), getacflg(3), getacmin(3), getacna(3), getacpol(3),
     au_poltostr(3), au_strtopol(3).

   Audit Event Interfaces
     Audit event interfaces support the look up of information from the
     audit_event(5) database: endauevent(3), setauevent(3), getauevent(3),
     getauevent_r(3), getauevnam(3), getauevnam_r(3), getauevnonam(3),
     getauevnonam_r(3), getauevnum(3), getauevnum_r(3).

   Audit I/O Interfaces
     Audit I/O interfaces support the processing and printing of tokens, as
     well as the reading of audit records: au_fetch_tok(3), au_print_tok(3),
     au_read_rec(3).

   Audit Mask Interfaces
     Audit mask interfaces convert support the conversion between strings and
     au_mask_t values.  They may also be used to determine if a particular
     audit event is matched by a mask: au_preselect(3), getauditflagsbin(3),
     getauditflagschar(3).

   Audit Notification Interfaces
     Audit notification routines track audit state in a form permitting effi-
     cient update, avoiding frequent system calls to check the kernel audit
     state: au_get_state(3), au_notify_initialize(3), au_notify_terminate(3).
     These interfaces are implemented only for Darwin/Mac OS X.

   Audit Token Interface
     Audit token interfaces permit the creation of tokens for use in creating
     audit records for submission to event streams.  Each interface converts a
     C type to its token_t representation.  au_to_arg(3), au_to_arg32(3),

     au_to_subject_ex(3), au_to_subject32_ex(3), au_to_subject64_ex(3),
     au_to_text(3), au_to_trailer(3).

   Audit User Interfaces
     Audit user interfaces support the look up of information from the
     audit_user(5) database: au_user_mask(3), endauuser(3), setauuser(3),
     getauuserent(3), getauuserent_r(3), getauusernam(3), getauusernam_r(3),
     getfauditflags(3).

AUTHORS
     This software was created by Robert Watson, Wayne Salamon, and Suresh
     Krishnaswamy for McAfee Research, the security research division of
     McAfee, Inc., under contract to Apple Computer, Inc.

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

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.

BUGS
     Bugs would not be unlikely.

     The libbsm library implementations are generally thread-safe, but not
     reentrant.

     The assignment of routines to classes could use some work, as it is
     decidely ad hoc.  For example, au_read_rec() should probably be consid-
     ered a stream routine.
