.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 "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 ;

|
.Dq expanded header
|
|
token is an expanded version of the
|
|
.Dq header
|
|
token, with the addition of a machine IPv4 or IPv6 address.
|
|
A 32-bit extended
|
|
.Dq header
|
|
token can be created using
|
|
.Xr au_to_header32_ex 3 ;
|
|
a 64-bit extended

|
|
tokens.
|
|
However, those tokens are used where the process being described is the

.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.
