    CISA, NCSC-UK, and FBI release OT secure connectivity principles

    Industry Or Public Sector Update

    CISA, the United Kingdom’s National Cyber Security Centre (NCSC-UK), the FBI, and international partners released Secure Connectivity Principles for Operational Technology for OT network environments, giving owners and operators a framework to design, secure, and manage connectivity. The guidance warns that exposed and insecure connectivity in connected industrial systems can increase risk from highly capable, opportunistic, and nation state-sponsored cyber threat actors, and urges secure-by-design principles to reduce attack surface and help protect critical infrastructure from physical harm, environmental damage, and disruption of essential services.
