As it was pointed out in https://issues.jenkins-ci.org/browse/JENKINS-5931 there is no option for restricting who can access what command, which can be a problem from the access control POV.
I would suggest a more simpler solution: having the ability to disable the whole irc command interface, this way the irc notification can still be used without allowing unauthorized access to random people.
I think this would be really easy to implement, and it would be a good-enough solution for most people.
