@subsubheading Auditd Service
The @code{(gnu services auditd)} module provides the following service.
@defvr {Scheme Variable} auditd-service-type
This is the type of the service that runs
@url{https://people.redhat.com/sgrubb/audit/,auditd},
a daemon that tracks security-relevant information on your system.
Examples of things that can be tracked:
@enumerate
@item
File accesses
@item
System calls
@item
Invoked commands
@item
Failed login attempts
@item
Firewall filtering
@item
Network access
@end enumerate
@command{auditctl} from the @code{audit} package can be used in order
to add or remove events to be tracked (until the next reboot).
In order to permanently track events, put the command line arguments
of auditctl into @file{/etc/audit/audit.rules}.
@command{aureport} from the @code{audit} package can be used in order
to view a report of all recorded events.
The audit daemon usually logs into the directory @file{/var/log/audit}.
@end defvr
