How viable is machine learning for cybersecurity?

Technology and security industries have turned to artificial intelligence and machine learning with a fervor once reserved for the latest iPhone release. On the expo floor at a cybersecurity show, professionals are hard pressed to collect a vendor flier without AI or ML mentioned at least once. Can the hype deliver -- let alone last? Machine learning is reaching the end of its peak of inflated expectations, poised for an imminent descent to the trough of disillusionment on Gartner's hype cycle. Business professionals who have been riding the ML high may be in store for a "hangover" when that trough hits, according to TK Keanini, distinguished engineer and product line CTO for analytics at Cisco, speaking at the Gartner Security & Risk Management Summit in Maryland on Monday.
