.SH NAME
audit.log \- audit trail file
.SH SYNOPSIS
.LP
.nf
\fB#include <bsm/audit.h>\fR
.fi
.LP
.nf
\fB#include <bsm/audit_record.h>\fR
.fi
.SH DESCRIPTION
.LP
\fBaudit.log\fR files are the depository for audit records stored locally or on
an NFS-mounted audit server. These files are kept in directories as specified
by the \fBp_dir\fR attribute of the \fBaudit_binfile\fR(5) plugin. They are
named to reflect the time they are created and are, when possible, renamed to
reflect the time they are closed as well. The name takes the form
.sp
.LP
\fIyyyymmddhhmmss\fR\fB\&.not_terminated.\fR\fIhostname\fR
.sp
.LP
when open or if \fBauditd\fR(1M) terminated ungracefully, and the form
.sp
.LP
\fIyyyymmddhhmmss\fR\fB\&.\fR\fIyyyymmddhhmmss\fR\fB\&.\fR\fIhostname\fR
.sp
.LP
when properly closed. \fByyyy\fR is the year, \fBmm\fR the month, \fBdd\fR day
in the month, \fBhh\fR hour in the day, \fBmm\fR minute in the hour, and
\fBss\fR second in the minute. All fields are of fixed width.
.sp
.LP
Audit data is generated in the binary format described below; the default for
audit is binary format. See \fBaudit_syslog\fR(5) for an alternate data
format.
.sp
.LP
The \fBaudit.log\fR file begins with a standalone \fBfile token\fR and
typically ends with one also. The beginning \fBfile token\fR records the
pathname of the previous audit file, while the ending \fBfile token\fR records
the pathname of the next audit file. If the file name is \fBNULL\fR the
appropriate path was unavailable.
.sp
.LP
The \fBaudit.log\fR files contains audit records. Each audit record is made up
of \fIaudit tokens\fR. Each record contains a header token followed by various
data tokens. Depending on the audit policy in place by \fBauditon\fR(2),
optional other tokens such as trailers or sequences may be included.
