12 audispd is an audit event multiplexor. It has to be started by the
13 audit daemon in order to get events. It takes audit events and distrib‐
14 utes them to child programs that want to analyze events in realtime.
15 When the audit daemon receives a SIGTERM or SIGHUP, it passes that sig‐
16 nal to the dispatcher, too. The dispatcher in turn passes those signals
17 to its child processes.
18 The child programs install a configuration file in a plugins directory,
20 /etc/audisp/plugins.d. Filenames are not allowed to have more than one
21 '.' in the name or it will be treated as a backup copy and skipped.
22 Options are given one per line with an equal sign between the keyword
23 and its value. The available options are as follows:
24 active The options for this are yes or no.
27 direction
29 The option is dictated by the plugin. In or out are the only
30 choices. You cannot make a plugin operate in a way it wasn't
31 designed just by changing this option.This option is to give a
32 clue to the event dispatcher about which direction events flow.
33 NOTE: inbound events are not supported yet.
34 path This is the absolute path to the plugin executable. In the case
36 of internal plugins, it would be the name of the plugin.
37 type This tells the dispatcher how the plugin wants to be run.
39 Choices are builtin and always. Builtin should always be given
40 for plugins that are internal to the audit event dispatcher.
41 These are af_unix and syslog. The option always should be given
42 for most if not all plugins. The default setting is always.
43 args This allows you to pass arguments to the child program. Gener‐
45 ally plugins do not take arguments and have their own config
46 file that instructs them how they should be configured. At the
47 moment, there is a limit of 2 args.
48 format The valid options for this are binary and string. Binary passes
50 the data exactly as the audit event dispatcher gets it from the
51 audit daemon. The string option tells the dispatcher to com‐
52 pletely change the event into a string suitable for parsing with
53 the audit parsing library. The default value is string.
