Artificial Intelligence could make the use of Intrusion Detection Systems a lot easier than it is today. They could learn the preferences of the security officers and show the kind of alerts first that the officer has previously been most interested. As always, the hardest thing with learning AIs, is to make them learn the right things. AIs could learn the same things as a rule-based system by watching a security officer work. AIs could also link together events that, by themselves, are insignificant but when combined may indicate that an attack is underway. In this article I’ll compare AI-based solutions to traditional IDS solutions, and analyze how the AIs could be taught.
