What happened
Confirmed via LinkedIn post from the official 'OWASP Top 10 for Large Language Model Applications' account (json-ld datePublished=2026-08-26): the Agent Control Standard (ACS) — an open, framework-agnostic standard for runtime agent control providing declarative hooks, policy enforcement, and observability across AI agent frameworks — was donated to the OWASP GenAI Security Project, becoming part of its Agentic Security Initiative portfolio. The project's GitHub org (genai-security-project/agent-control-standard) shows active recent commit history (Apache-2.0 licensed).
Why it matters
This brings a previously independent runtime-control specification for AI agents under OWASP's community-governed, vendor-neutral umbrella, alongside the LLM Top 10 and Agentic Top 10. It gives builders and security teams a standardized way to enforce policy and maintain visibility into agent behavior at runtime rather than relying on ad hoc, framework-specific controls — directly relevant to the agentic-identity/authorization theme dominating this week's guidance landscape.
Action needed
Evaluate ACS as a candidate runtime-control layer for agent deployments; monitor the OWASP GenAI Security Project repo as the standard matures under community governance; consider contributing via issues/PRs.
