The video lesson "Stride Model Assessing Security Threats Across Six Dimensions" explains the STRIDE model, which is a widely used framework for evaluating security threats in software development.

The model divides security threats into six categories: Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege. The video discusses each of these categories in detail and provides examples of how they can be exploited in real-world scenarios.

The lesson is designed to help viewers understand the importance of evaluating security threats across multiple dimensions and to provide them with the knowledge and tools they need to apply the STRIDE model to their own software development projects.
