Show HN: A free agentic AI security reference (CC BY-NC-ND 4.0) (www.nextkicklabs.com)

The "Agentic AI Security Stack" has been released as a free, comprehensive 200-page reference guide aimed at securing agentic AI systems. This significant resource provides a unified threat model, detailing twelve security layers, including threat modeling, credential architecture, isolation controls, and regulatory compliance. Each chapter of the reference maps to established frameworks such as OWASP, MITRE ATLAS, and CSA MAESTRO, allowing practitioners to identify and address security vulnerabilities effectively. The book is licensed under Creative Commons, enabling broad sharing and collaboration without legal constraints. The guide addresses a critical gap in the AI/ML community, where many organizations lack a cohesive security framework for agentic AI deployments, leading to vulnerabilities that attackers can exploit. By emphasizing a threat-focused approach that starts from the attacker's objectives, the resource helps teams mitigate risks systematically. Security leaders are encouraged to utilize this reference to map their current deployments against the detailed kill chain and enhance their security posture by understanding the specific layers and controls relevant to their systems. The collaboration involved in the guide's development, including public discussions and peer review, ensures that it reflects the latest insights and best practices in securing agentic AI technologies.
