Artificial intelligence (AI) is currently hailed as a silver bullet against almost everything. So it's no wonder that OT security is also expected to benefit from a self-learning system. Together with Rhebo and other technology partners, the Fraunhofer IOSB has investigated the possibilities in the AICAS project. The automation of AI-triggered mitigation mechanisms is not (yet) recommended in OT.
