The concept articulates a credible adversary and their potential capabilities against which a system or facility is designed to protect. It represents a threat profile, encompassing potential attack methods, resources, and intentions. For example, in the context of a nuclear power plant, this might include a determined group attempting to cause a radiological release using explosives and insider assistance. This profile dictates the security measures implemented.
Establishing this benchmark is crucial for risk management, security planning, and regulatory compliance. It provides a foundation for engineering safeguards and operational procedures, ensuring appropriate protection levels. Historically, the development of such standards has been driven by incidents and evolving geopolitical landscapes, prompting continuous refinement to address emerging risks and vulnerabilities. Its consistent application contributes significantly to resilience and safety.
