audispd is an audit event multiplexor. It has to be started by the
audit daemon in order to get events. It takes audit events and
distributes them to child programs that want to analyze events in
realtime. When the audit daemon receives a SIGTERM or SIGHUP, it
passes that signal to the dispatcher, too. The dispatcher in turn
passes those signals to its child processes.
The child programs install a configuration file in a plugins
directory, /etc/audisp/plugins.d. Filenames are not allowed to have
more than one '.' in the name or it will be treated as a backup copy
and skipped. Options are given one per line with an equal sign
between the keyword and its value. The available options are as
active The options for this are yes or no.direction
The option is dictated by the plugin. In or out are the only
choices. You cannot make a plugin operate in a way it wasn't
designed just by changing this option.This option is to give a
clue to the event dispatcher about which direction events
flow. NOTE: inbound events are not supported yet.
path This is the absolute path to the plugin executable. In the
case of internal plugins, it would be the name of the plugin.
type This tells the dispatcher how the plugin wants to be run.
Choices are builtin and always.Builtin should always be
given for plugins that are internal to the audit event
dispatcher. These are af_unix and syslog. The option always
should be given for most if not all plugins. The default
setting is always.args This allows you to pass arguments to the child program.
Generally plugins do not take arguments and have their own
config file that instructs them how they should be configured.
At the moment, there is a limit of 2 args.
format The valid options for this are binary and string.Binary
passes the data exactly as the audit event dispatcher gets it
from the audit daemon. The string option tells the dispatcher
to completely change the event into a string suitable for
parsing with the audit parsing library. The default value is
