Security design principles, STRIDE threat modeling, OWASP Top 10 architectural mitigations, and secure patterns. Load when designing systems or reviewing architecture for security.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Security by Design ## OWASP Security Design Principles Apply these during design -- retrofitting security is 10-100x more expensive. | # | Principle | Architect Action | |---|-----------|-----------------| | 1 | Security by Design | Include security requirements in architecture documents | | 2 | Security by Default | Ship restrictive defaults; require explicit opt-in for relaxed settings | | 3 | Defense in Depth | Layer controls: WAF + input validation + output encoding + parameterized queries | | 4 | Fail Secure | Deny access on error; closed-by-default network policies | | 5 | Least Privilege | Scoped service accounts; time-limited tokens; minimum permissions | | 6 | Compartmentalize | Network segmentation; separate databases per trust level | | 7 | Separation of Duties | Separate deployment approval from code authorship | | 8 | Economy of Mechanism | Minimize attack surface; simple, auditable security code | | 9 | Complete Mediation | Check authorization on every request; no cached auth decisions | | 10 | Open Design | Use published, peer-reviewed algorithms; no security-through-obscurity | | 11 | Least Common Mechanism | Separate admin and user interfaces | …

How to install
mdr add nwave-ai/nwave/nw-security-by-design@sha256:62bb8bf1da2e1240The line at the top of this page pins the label git:20260320.d98f3cb, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
