Adversary model

An adversary model is a structured cybersecurity framework used to profile potential threat actors by analyzing their intentions, motivations, capabilities, resources, and typical tactics, techniques, and procedures (TTPs). It goes beyond generic threat assessments by providing a granular understanding of who an organization's likely attackers are, what their objectives might be, and how they are expected to operate. This profiling is continuously refined through ongoing threat intelligence analysis and tailored to an organization's specific assets and operational context.

By leveraging an adversary model, cybersecurity professionals can anticipate attack vectors, predict adversarial behaviors, and proactively align their defensive strategies. It directly informs critical security functions such as security architecture design, investment prioritization, penetration testing methodologies, and incident response planning. Ultimately, an adversary model transforms reactive security postures into proactive, intelligence-driven defenses, enabling organizations to systematically mitigate risks and protect critical infrastructure against an ever-evolving threat landscape.
