In the world of IT cybersecurity, particularly among corporate enterprises and especially financial systems, automated patching is used to close that gap as quickly as possible. But most OT assets can’t use the same approach.
Any updates must observe the sensitivity around critical infrastructure, as OT systems are often a part of safety-critical systems or involve some form of safety integrity classification. That means careful testing, extensive reviews from independent third parties, and official approvals.
Because of the critical role these systems play in safety, reliability and continuity of service, many organisations restrict implementing patches to timeframes that align with other updates, dependent on specific regulatory standards in their sector. While these safeguards are essential, the increased delay makes the window of opportunity for cyberattacks wider in OT.
New AI models will make this an even bigger liability, one that must be handled urgently, mainly through vulnerability management. To keep up with the rapid pace, organisations must prioritise resilience, recovery, and engineering-led cybersecurity.
