The new reality of critical infrastructure security in the age of hybrid threats
The UK’s critical national infrastructure (CNI) is entering a converged threat era - one where cyber, physical and aerial risks are overlapping attack surfaces targeting the same high-value assets. Furthermore, data centers have been formally designated as CNI, elevating both their strategic importance and their exposure to attack.
Historically, organizations responsible for critical assets have approached security in distinct domains, silos maybe. Cybersecurity teams protect networks and data, physical security teams manage access control and perimeter protection and airspace, in most cases, has remained largely ungoverned - until the past decade or so.
