Which of the following is not part of the STRIDE model?

The STRIDE model is a framework used in threat modeling to identify and categorize potential security threats. It focuses on six types of threats that may affect systems or applications, which are organized under the acronym STRIDE: Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege.

In this context, the correct answer pertains to "Resiliency," which is not one of the categories defined within the STRIDE model. Resiliency generally refers to the ability of a system to withstand failures and recover from adverse conditions but does not specifically classify threats in the way that STRIDE does. The other terms—Spoofing, Tampering, and Information Disclosure—are all critical components of STRIDE, addressing different forms of security threats that can compromise the integrity, availability, or confidentiality of a system.

Understanding this model is essential for identifying and addressing vulnerabilities in cloud security and other areas of information security. By recognizing what constitutes a threat under STRIDE, security professionals can better analyze risk and implement appropriate countermeasures.
