STRIDE Threat Modeling Framework

Information Technology > Transaction security and virus protection

Description

The STRIDE Threat Modeling Framework is a proactive security methodology designed for Technical and Enterprise Architects to identify and mitigate potential threats during the design and architecture phases of software systems. Developed by Microsoft, STRIDE stands for Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege—six key threat categories that help architects anticipate and address vulnerabilities before coding begins. By thinking like attackers, architects can uncover design flaws early, aligning with a "shift-left" security approach that emphasizes early detection and resolution of security issues, ultimately enhancing the overall security posture of software projects.

Expected Behaviors

✎
LEVEL 1

Fundamental Awareness

Individuals at this level have a basic understanding of threat modeling and its significance in software design. They can identify the six key threat categories in the STRIDE framework and recognize the role of threat modeling in the software development lifecycle.

🌱
LEVEL 2

Novice

Novices can explain the purpose and benefits of the STRIDE framework, describe each threat category, and identify common security threats associated with each category. They are beginning to apply this knowledge in practical scenarios.

🌍
LEVEL 3

Intermediate

At the intermediate level, individuals can apply the STRIDE framework to simple software architecture diagrams, document identified threats, and prioritize them based on potential impact and likelihood. They are capable of integrating threat modeling into projects.

⭐
LEVEL 4

Advanced

Advanced practitioners integrate STRIDE threat modeling into complex software projects, facilitate workshops with cross-functional teams, and develop mitigation strategies for identified threats. They play a key role in ensuring security is considered during the design phase.

🏆
LEVEL 5

Expert

Experts lead organization-wide initiatives to adopt STRIDE practices, evaluate and improve existing processes, and mentor others in advanced techniques. They are responsible for driving the strategic implementation of threat modeling across the organization.
