1.0 alpha 1, an implementation of the documented Sun Basic Security Module (BSM) Audit API and file format, as well as local extensions to support the Mac OS X and FreeBSD operating systems. Also included are command line tools for audit trail reduction and conversion to text, as well as documentation of the commands, file format, and APIs. This distribution is the foundation for the TrustedBSD Audit implementation, and is a pre-release. This is the first in a series of commits to introduce support for Common Criteria CAPP security event audit support. This software has been made possible through the generous contributions of Apple Computer, Inc., SPARTA, Inc., as well as members of the TrustedBSD Project, including Wayne Salamon <wsalamon> and Tom Rhodes <trhodes>. The original OpenBSM implementation was created by McAfee Research under contract to Apple Computer, Inc., as part of their CC CAPP security evaluation. Many thanks to: wsalamon, trhodes Obtained from: TrustedBSD Project

.Sh SYNOPSIS
|
|
.In libbsm.h
|
|
.Ft int
|
|
.Fn au_fetch_tok "tokenstr_t *tok" "u_char *buf" "int len"
|
|
.Ft void
|
|
.Fn au_print_tok "FILE outfp" "tokenstr_t *tok" "char *del" "char raw" "char sfrm"

.Fn au_read_rec "FILE *fp" "u_char **buf"
|
|
.Sh DESCRIPTION
|
|
These interfaces support input and output (I/O) involving audit records,
|
|
internalizing an audit record from a byte stream, converting a token to
|
|
either a raw or default string, and reading a single record from a file.
|
|
.Pp
|
|
.Fn au_fetch_tok
|
|
reads a token from the passed buffer
|
|
.Va buf
|
|
of length
|
|
.Va len
|
|
bytes, and returns a pointer to the token via
|
|
.Va tok .
|
|
.Pp
|
|
.Fn au_print_tok
|
|
prints a string form of the token
|
|
.Va tok
|
|
to the file output stream
|
|
.Va outfp,
|
|
either in default mode, or raw mode if
|
|
.Va raw
|
|
is set non-zero.
|
|
The delimiter
|
|
.Va del
|
|
is used when printing.
|
|
.Pp
|
|
.Fn au_read_rec
|
|
reads an audit record from the file stream
|
|
.Va fp ,
|
|
and returns an allocated memory buffer containing the record via
|
|
.Va *buf ,
|
|
which must be freed by the caller using
|
|
.Xr free 3 .
|
|
.Pp
|
|
A typical use of these routines might open a file with
|
|
.Xr fopen 3 ,
|
|
then read records from the file sequentially by calling
|
|
.Fn au_read_rec .
|
|
Each record would be broken down into components tokens through sequential
|
|
calls to
|
|
.Fn au_fetch_tok
|
|
on the buffer, and then invoking
|
|
.Fn au_print_tok
|
|
to print each token to an output stream such as
|
|
.Dv stdout .
|
|
On completion of the processing of each record, a call to
|
|
.Xr free 3
|
|
would be used to free the record buffer.
|
|
Finally, the source stream would be closed by a call to
|
|
.Xr fclose 3 .
|
|
.Sh RETURN VALUES
|
|
.Fn au_fetch_tok
|
|
and
|
|
.Fn au_read_rec
|
|
return 0 on success, or -1 on failure along with additional error information
|
|
returned via
|
|
.Va errno .

|
|
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.
|
|
.Pp
|
|
The Basic Security Module (BSM) interface to audit records and audit event
|
|
stream format were defined by Sun Microsystems.
|
|
.Sh 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.
|
|
.Sh BUGS
|
|
.Va errno
|
|
may not always be properly set in the event of an error.
