Careful Adoption of Agentic AI Services

Joint guidance co-authored by ASD's ACSC, CISA, NSA, the Canadian Centre for Cyber Security, NCSC-NZ and NCSC-UK on securing LLM-based agentic AI systems across critical infrastructure and defence. It catalogs agentic-AI-specific risk categories — privilege compromise, scope creep, confused-deputy attacks, identity spoofing, insecure static permission checks, indirect prompt injection, specification gaming and deceptive/emergent agent behaviour — with concrete scenario examples, and lays out best practices for designing, developing, deploying and operating agents securely.

TL;DR Six-nation cyber agencies' joint guidance on agentic AI risks (privilege compromise, confused deputy, prompt injection, deceptive behaviour) and secure-lifecycle best practices.
