AUDITD(8) Maintenance Commands and Procedures AUDITD(8)

NAME

auditd - audit daemon

SYNOPSIS

/usr/sbin/auditd

DESCRIPTION

The audit daemon, auditd, controls the generation and location of audit
trail files and the generation of syslog messages based on its
configuration, stored in smf(7) and managed using the auditconfig(8)
command.


audit(8) is used to control auditd. It can cause auditd to:

o close the current audit file and open a new one;

o close the current audit file, reread its configuration and
open a new audit file;

o close the audit trail and terminate auditing.

Auditing Conditions

The audit daemon invokes the program audit_warn(8) under the following
conditions with the indicated options:

audit_warn soft pathname

The file system upon which pathname resides has exceeded the minimum
free space limit defined by the p_minfree attribute of the
audit_binfile plugin. A new audit trail has been opened on another
file system.


audit_warn allsoft

All available file systems have been filled beyond the minimum free
space limit. A new audit trail has been opened anyway.


audit_warn hard pathname

The file system upon which pathname resides has filled or for some
reason become unavailable. A new audit trail has been opened on
another file system.


audit_warn allhard count

All available file systems have been filled or for some reason become
unavailable. The audit daemon will repeat this call to audit_warn at
intervals of at least twenty seconds until space becomes available.
count is the number of times that audit_warn has been called since
the problem arose.


audit_warn tmpfile

There was a problem creating a symlink from /var/run/.audit.log to
the current audit log file.


audit_warn nostart

There was an internal error starting auditing.


audit_warn auditoff

The internal system audit condition has been changed to not be
AUC_AUDITING by someone other than the audit daemon. This causes the
audit daemon to exit.

NOTES

If the audit policy perzone is set, auditd runs in each zone, starting
automatically when the local zone boots. If a zone is running when the
perzone policy is set, auditing must be started manually in local zones.
It is not necessary to reboot the system or the local zone to start
auditing in a local zone. auditd can be started with "/usr/sbin/audit -s"
and will start automatically with future boots of the zone.


When auditd runs in a local zone, the configuration is taken from the
local zone's /etc/security directory's files: audit_class, and
audit_event.


Configuration changes do not affect audit sessions that are currently
running, as the changes do not modify a process's preselection mask. To
change the preselection mask on a running process, use the -setpmask
option of the auditconfig command (see auditconfig(8)). If the user logs
out and logs back in, the new configuration changes will be reflected in
the next audit session.


The auditd service is managed by the service management facility, smf(7),
under the service identifier:

svc:/system/auditd


The service's status can be queried using the svcs(1) command. While
administrative actions on this service, such as enabling, disabling, or
requesting restart, can be performed using svcadm(8), the audit(8)
command is the preferred administrative interface.
