AI in Cybersecurity: Where We Stand & Where We Need to Go

How security practitioners can incorporate expert knowledge into machine learning algorithms that reveal security insights, safeguard data, and keep attackers out.

Bayesian Belief Networks for Cybersecurity
Really nice article highlighting the exact things we at Haystax Technology talk about with the use of AI in cybersecurity. It seems every vendor has launched a new version of their product in the past year with the tagline of "New and improved with AI". 

There are great places where ML is perfect for cybersecurity, but only as a part of the solution. The heart of our Constellation Analytics Platform is a Bayesian Inference Network built over years of research to reason like a team of cyber experts across weak inputs from disparate sensor systems. Some of those sensors need ML techniques to find the real signal, some don't - but they all come together in a BayesNet that prioritizes the threat and ultimately the risk. 

We believe this is the only viable approach today given what you highlighted of lack of training data, and even if you had some training data, sensor outputs change frequently as the environment changes. Only with additional context can you uncover those malicious events that represent the highest risks.
