Planning and Design Phase Tools

Threat modeling tools transform security analysis from whiteboard exercises to systematic, repeatable processes. Microsoft Threat Modeling Tool pioneered accessible threat modeling, providing a free solution with extensive threat libraries and mitigation guidance. IriusRisk offers enterprise-grade threat modeling with risk quantification and compliance mapping. ThreatModeler provides collaborative threat modeling with extensive integration capabilities. These tools guide teams through structured threat analysis, ensuring comprehensive coverage.

Security requirements management tools help organizations track security needs alongside functional requirements. OWASP SecurityRAT (Requirements Automation Tool) generates security requirements based on project characteristics. SD Elements automates security requirements selection based on technology stack and compliance needs. These tools ensure security requirements aren't overlooked and provide traceability throughout development.

Architecture analysis tools evaluate designs for security weaknesses before implementation begins. Tools like Lattix and Structure101 analyze architectural dependencies to identify security-critical components. Cloud security posture tools preview infrastructure security before deployment. These early-stage tools prevent architectural security flaws that would be expensive to fix later.
