Threat Modeling

Threat modeling is a proactive security practice that systematically identifies potential threats to a system, assesses the likelihood and impact of each threat, and determines appropriate countermeasures. Popular frameworks include STRIDE (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege), PASTA (Process for Attack Simulation and Threat Analysis), and attack trees.

Effective threat modeling typically involves four key questions: What are we building? What can go wrong? What are we going to do about it? Did we do a good job? This process should happen during design (before code is written) and be updated as the system evolves.

Threat modeling helps organizations allocate security resources effectively by focusing on the most likely and impactful threats rather than trying to defend against everything equally.

How APVISO tests for this: While threat modeling is a design-time activity, APVISO validates threat model assumptions by testing for the threats you've identified. After modeling potential attacks, use APVISO to verify that your mitigations actually work and to discover threats your model may have missed.
