.Sh NAME
.Nm audit
.Nd "Basic Security Module (BSM) file format"
.Sh DESCRIPTION
The
.Nm
file format is based on Sun's Basic Security Module (BSM) file format, a
token-based record stream to represent system audit data.
This file format is both flexible and extensible, able to describe a broad
range of data types, and easily extended to describe new data types in a
moderately backward and forward compatible way.
.Pp
BSM token streams typically begin and end with a
.Dq file
token, which provides time stamp and file name information for the stream;
when processing a BSM token stream from a stream as opposed to a single file
source, file tokens may be seen at any point between ordinary records
identifying when particular parts of the stream begin and end.
All other tokens will appear in the context of a complete BSM audit record,
which begins with a
.Dq header
token, and ends with a
.Dq trailer
token, which describe the audit record.
Between these two tokens will appear a variety of data tokens, such as
process information, file path names, IPC object information, MAC labels,
socket information, and so on.
.Pp
The BSM file format defines specific token orders for each record event type;
however, some variation may occur depending on the operating system in use,
what system options, such as mandatory access control, are present.
.Pp
This manual page documents the common token types and their binary format, and
is intended for reference purposes only.
It is recommended that application programmers use the
.Xr libbsm 3
interface to read and write tokens, rather than parsing or constructing
records by hand.
.Ss File Token
The
.Dq file
token is used at the beginning and end of an audit log file to indicate
when the audit log begins and ends.
It includes a pathname so that, if concatenated together, original file
boundaries are still observable, and gaps in the audit log can be identified.
A
.Dq file
token can be created using
.Xr au_to_file 3 .
.Bl -column -offset 3n ".No Terminal Address Type/Length" ".No N bytes + 1 NUL"
.It Sy "Field	Bytes	Description"
.It "Token ID	1 byte	Token ID"

.It "Microseconds	4 bytes	File time stamp"
.It "File name lengh	2 bytes	File name of audit trail"
.It "File pathname	N bytes + 1 NUL	File name of audit trail"
.El
.Ss Header Token
The
.Dq header
token is used to mark the beginning of a complete audit record, and includes
the length of the total record in bytes, a version number for the record
layout, the event type and subtype, and the time at which the event occurred.
A 32-bit
.Dq header
token can be created using
.Xr au_to_header32 3 ;
a 64-bit
.Dq header
token can be created using
.Xr au_to_header64 3 .

tokens.
However, those tokens are used where the process being described is the
target of the operation, not the authorizing party.

.Dq subject
token can be created using
