Which of the following is NOT a part of the STRIDE methodology?

The STRIDE methodology is a well-known framework used in threat modeling to identify and categorize potential security threats in software systems. The acronym STRIDE stands for Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege. Each of these categories represents a different type of security threat that can be addressed during the software design and development process.

In this context, selecting "C" as the correct answer highlights that "Trike" is indeed not a part of the STRIDE methodology. Trike is a different threat modeling framework that focuses on risk management and the identification of threats through a unique approach, but it does not fall under the STRIDE categories. STRIDE is exclusively focused on specific threat types outlined by its acronym, making "Trike" an unrelated option in this scenario.

Understanding these methodologies and their distinctions is crucial for comprehending how threats can be assessed and mitigated, ensuring a secure software design.
