This is one of the things you need to know if you are planning to work towards CISSP cybersecurity certification.

The video talks about the theory on creating a data flow diagram, and how the analysis is then applied. In a future video I plan to create another video with a practical example of how to apply STRIDE analysis to an open source software projects.

The 6 steps to STRIDE are:

• Spoofing - imitating someone or something else to gain access to a system or higher privilage
• Tampering - unauthorized changes to data or configuration
• Repudiation - identifying who has done what on the system
• Information Disclosure - unathorized access to information that is confidential or secret
• Denial of Service DoS - preventing access to a service
• Elevation of privilege - increasing the level of privilege after logging in as less priveleged user
