Which component is NOT part of the STRIDE model that identifies threats?

The STRIDE model is a framework used for identifying different types of security threats in software design and systems. Each component of STRIDE represents a specific category of threat:

• Tampering refers to unauthorized modifications of data.
• Repudiation involves users denying their actions or transactions, which can lead to accountability issues.
• Information Disclosure pertains to unauthorized access to information, making it available to unintended recipients.

Encryption, while an essential security measure, is not a category of threat recognized by the STRIDE model. Instead, it serves as a protective technology aimed at mitigating some of the threats identified by STRIDE, such as information disclosure. Understanding these categories helps security professionals assess and mitigate potential vulnerabilities in their systems and applications by focusing on the correct threats rather than security controls.
