THE NCSC has observed a rise in cyberattacks targeting operational technology (OT) systems across various sectors, necessitating heightened awareness and security measures from organizations. Key recommendations include assessing OT architecture to eliminate internet exposure, strengthening access controls, monitoring network connectivity, and maintaining secure backups. The advisory also emphasizes the importance of separating OT from business networks to contain potential impacts of cyber incidents.
Despite the focus on OT systems, the threat of disruptive cyber activity affects all sectors, highlighting the need for comprehensive cyber resilience strategies.
