Open Security Architecture Rebooted After 15 Years of Dormancy

Open Security Architecture, a security project from the 2000s, has been relaunched with a modern website and structured data. It now includes 39 security patterns, covering topics such as Zero Trust, AI agent security, DevSecOps pipelines, passkeys, and cyber resilience (DORA/PRA). Each pattern is associated with specific NIST 800-53 Rev 5 controls and offers a free self-assessment tool to evaluate the environment against the pattern's control areas. The project is licensed under CC BY-SA 4.0 and the data is available on GitHub.
