36.Nm 37file format is based on Sun's Basic Security Module (BSM) file format, a 38token-based record stream to represent system audit data. 39This file format is both flexible and extensible, able to describe a broad 40range of data types, and easily extended to describe new data types in a 41moderately backward and forward compatible way. 42.Pp 43BSM token streams typically begin and end with a 44.Dv file 45token, which provides time stamp and file name information for the stream; 46when processing a BSM token stream from a stream as opposed to a single file 47source, file tokens may be seen at any point between ordinary records 48identifying when particular parts of the stream begin and end. 49All other tokens will appear in the context of a complete BSM audit record, 50which begins with a 51.Dv header 52token, and ends with a 53.Dv trailer 54token, which describe the audit record. 55Between these two tokens will appear a variety of data tokens, such as 56process information, file path names, IPC object information, MAC labels, 57socket information, and so on. 58.Pp 59The BSM file format defines specific token orders for each record event type; 60however, some variation may occur depending on the operating system in use, 61what system options, such as mandatory access control, are present. 62.Pp 63This manual page documents the common token types and their binary format, and 64is intended for reference purposes only. 65It is recommended that application programmers use the 66.Xr libbsm 3 67interface to read and write tokens, rather than parsing or constructing 68records by hand. 69.Ss File Token 70The 71.Dv file 72token is used at the beginning and end of an audit log file to indicate 73when the audit log begins and ends. 74It includes a pathname so that, if concatenated together, original file 75boundaries are still observable, and gaps in the audit log can be identified. 76A 77.Dv file 78token can be created using 79.Xr au_to_file 3 . 80.Bl -column

contract to Apple Computer Inc. in 2004. 613It was subsequently adopted by the TrustedBSD Project as the foundation for 614the OpenBSM distribution. 615.Sh BUGS 616The 617.Dv How to print 618field in
