AUDIT(4)						   BSD Kernel Interfaces Manual 						  AUDIT(4)

NAME
audit -- Security Event Audit SYNOPSIS
options AUDIT DESCRIPTION
Security Event Audit is a facility to provide fine-grained, configurable logging of security-relevant events, and is intended to meet the requirements of the Common Criteria (CC) Common Access Protection Profile (CAPP) evaluation. The FreeBSD audit facility implements the de facto industry standard BSM API, file formats, and command line interface, first found in the Solaris operating system. Information on the user space implementation can be found in libbsm(3). Audit support is enabled at boot, if present in the kernel, using an rc.conf(5) flag. The audit daemon, auditd(8), is responsible for con- figuring the kernel to perform audit, pushing configuration data from the various audit configuration files into the kernel. Audit Special Device The kernel audit facility provides a special device, /dev/audit, which is used by auditd(8) to monitor for audit events, such as requests to cycle the log, low disk space conditions, and requests to terminate auditing. This device is not intended for use by applications. Audit Pipe Special Devices Audit pipe special devices, discussed in auditpipe(4), provide a configurable live tracking mechanism to allow applications to tee the audit trail, as well as to configure custom preselection parameters to track users and events in a fine-grained manner.

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. Support for kernel audit first appeared in FreeBSD 6.2. AUTHORS
This software was created by McAfee Research, the security research division of McAfee, Inc., under contract to Apple Computer Inc. Addi- tional authors include Wayne Salamon, Robert Watson, and SPARTA Inc. The Basic Security Module (BSM) interface to audit records and audit event stream format were defined by Sun Microsystems. This manual page was written by Robert Watson <rwatson@FreeBSD.org>. BUGS
The FreeBSD kernel does not fully validate that audit records submitted by user applications are syntactically valid BSM; as submission of records is limited to privileged processes, this is not a critical bug. Instrumentation of auditable events in the kernel is not complete, as some system calls do not generate audit records, or generate audit records with incomplete argument information. Mandatory Access Control (MAC) labels, as provided by the mac(4) facility, are not audited as part of records involving MAC decisions. BSD

NAME
audit -- audit management utility SYNOPSIS
audit -e | -i | -n | -s | -t DESCRIPTION
The audit utility controls the state of the audit system. One of the following flags is required as an argument to audit: -e Forces the audit system to immediately remove audit log files that meet the expiration criteria specified in the audit control file without doing a log rotation. -i Initializes and starts auditing. This option is currently for Mac OS X only and requires auditd(8) to be configured to run under launchd(8). -n Forces the audit system to close the existing audit log file and rotate to a new log file in a location specified in the audit con- trol file. Also, audit log files that meet the expiration criteria specified in the audit control file will be removed. -s Specifies that the audit system should [re]synchronize its configuration from the audit control file. A new log file will be cre- ated. The attributable flags parameter from the audit_control(5) configuration file is set at login time and is not synchronized with this flag. -t Specifies that the audit system should terminate. Log files are closed and renamed to indicate the time of the shutdown. NOTES
The auditd(8) daemon must already be running. Optionally, it can be configured to be started on-demand by launchd(8) (Mac OS X only). The audit utility requires audit administrator privileges for successful operation. FILES
