The US Cybersecurity and Infrastructure Security Agency (CISA), the UK’s National Cyber Security Centre (NCSC), the Federal Bureau of Investigation (FBI), and international partners have released a new set of security principles aimed at securing operational technology (OT) environments. The guidance addresses the growing risks associated with insecure connectivity in systems that support essential services, providing a framework to help organizations design and manage secure connectivity in OT networks. The document emphasizes the importance of embedding security into network design from the outset to reduce exposure to both highly capable and opportunistic adversaries, including nation-state actors. It highlights the increased interconnection between industrial systems and enterprise networks, which has improved efficiency but expanded the attack surface for cyber threat actors.
