Cybersecurity Agent Skills v1.2.0 — Five Framework Coverage
The world's first open-source cybersecurity skills library mapped to 5 industry frameworks.
v1.2.0 adds MITRE ATLAS v5.5, MITRE D3FEND v1.3, and NIST AI RMF 1.0 mappings to every skill — joining the existing MITRE ATT&CK Enterprise and NIST CSF 2.0 coverage. No other open-source library maps cybersecurity skills for AI agents across all five frameworks simultaneously.
What's new in v1.2.0
Three new framework mappings
| Framework | Skills mapped | What it adds |
|---|---|---|
| MITRE ATLAS v5.5 | 81 | AI/ML adversarial threat techniques — model poisoning, prompt injection defense, AI supply chain attacks, agentic AI escape-to-host |
| MITRE D3FEND v1.3 | 139 | Defensive technique taxonomy — 267 countermeasures across Model, Harden, Detect, Isolate, Deceive, Evict, Restore |
| NIST AI RMF 1.0 | 85 | AI risk management — Govern, Map, Measure, Manage functions for AI system lifecycle |
