OpenBSM is an open-source implementation of Sun's BSM event auditing file format and API. Originally created for Apple Computer by McAfee Research, OpenBSM is now maintained by volunteers and through the generous contributions of several organizations.
OpenBSM includes several command line tools, including auditreduce(8) and praudit(8) for reducing and printing audit trails, as well as the libbsm(3) library to manage configuration files, generate audit records, and parse and print audit trails. It also includes the auditd(8) audit configuration daemon, and the auditdistd(8) audit-trail distribution daemon.
Coupled with a kernel audit implementation, OpenBSM can be used to maintain system audit streams, and is a foundation for a full audit-enabled system. Portions of OpenBSM, including include files and token-building routines, are reusable in a kernel audit implementation, and may be found in the FreeBSD and macOS kernels.
OpenBSM consists of several directories:
bin/ Audit-related command line tools and daemons
bsm/ Library header files for BSM
compat/ Compatibility code to build on various operating systems
etc/ Sample /etc/security configuration files
libauditd/ Common audit management functions for auditd and launchd
libbsm/ Implementation of BSM library interfaces and man pages
man/ System call and configuration file man pages
m4/ Input files for m4 macro text processor
modules/ Directory for auditfilterd module source
sys/ System header files for BSM
test/ Test token sets and geneneration program
tools/ Tool directory, including audump to dump databases
The following programs are included with OpenBSM:
audit Command line audit control tool
auditd Audit management daemon
auditdistd Audit trail distribution daemon
auditfilterd Experimental event monitoring framework
auditreduce Audit trail reduction tool
audump Debugging tool to parse and print audit databases
praudit Tool to print audit trails
Please see the file INSTALL for build and installation instructions.
