Harman CISO: AI-based ‘cyber analysts’ can fix false alarm problem in EDR solutions

Automated and AI-based endpoint, detection and response (EDR) solutions are adept at finding anomalies across your network, but not without a major pain point: Too often, they lack the context to understand when an anomaly is a perfectly acceptable sanctioned event, according to Maurice Stebila, CISO at Harman International Industries, a division of Samsung that manufactures visual and audio devices, connected car systems, enterprise automat​ion solutions and connected services.

Security analysts end up wasting their time investigating these sanctioned events, instead of focusing on potentially more serious anomalies that might actually constitute a threat, continued Stebila, in an interview with SC Media at the 2020 RSA cybersecurity conference.

But Stebila said he believes a solution may be forthcoming in the form of an AI-based digital cyber analyst that can efficiently analyze anomaly data and perform a forensics investigation. Stebila said such a tool would "supplement the folks on my team in terms of identifying and remediating and getting that dwell time down."

Stebila does not think that such a tool would replace human analysts. Rather, he said, "I believe it's going to be the first tool of choice. It's going to allow teams and cyber analysts today to identify and to complete their forensics much more quickly, in minutes versus... hours of investigation..."

During the interview, Stebila also touched on third-party risk and the prospects of how to assess partners' security postures using risk scoring tools and services.

Brands operated by Stamford, Conn.-based Harman reportedly include AKG, AMX, Becker, Crown, Harman Kardon, Infinity, JBL, Lexicon, dbx, DigiTech, Mark Levinson, Martin, Revel, Soundcraft, Studer, Arcam, Bang & Olufsen and BSS Audio.
