Cyber Assessment Framework (CAF) 4.0 Compliance
Summary: The UK's National Cyber Security Centre has released CAF 4.0, a Cyber Assessment Framework that the source says moves beyond compliance to demand proactive, intelligence-driven defense, requiring organizations to understand adversaries, anticipate attacks, and maintain continuous vigilance. It applies to operators of critical infrastructure and essential functions across energy, transport, water supply, digital infrastructure, manufacturing of critical products, food, space, and public administration.
What you should know: CAF 4.0 requires continuous, near real-time monitoring without disrupting operations, and the source notes that traditional IT security tools can cause latency issues in OT environments - so the monitoring mandate lands squarely on infrastructure where the usual tooling carries operational risk.
