First published on Dive Brief: Industrial control systems (ICS) have become more of a target for malicious threat actors, but the strategies used to defend that environment do not easily translate from the information technology space to the operational technology environment, according to a panel of cybersecurity experts at the Hack the Capitol event last week. After operating in an almost isolated state for years, ICS have become more interconnected within the OT environment and connected to the IT environment, making them highly vulnerable to cyberattacks, according to David Weinstein, associate partner at McKinsey & Co. Government needs to do a better job of understanding the risk/reward ratio of any action they take to deter malicious activity, panelists said. This requires the government to speak the language of business so ICS owners and operators better understand how they will lower their risk profile through more proactive engagement.
