TL;DR: AI security failures now surface at runtime through prompt injection, tool misuse, data leakage, and model extraction, according to AccuKnox, which argues that NIST AI RMF, OWASP LLM Top 10, and EU AI Act requirements only matter when they are enforced continuously. The operational shift is from point tools and questionnaires to a lifecycle control plane that ties inventory, policy, monitoring, and audit evidence together.

By the numbers:
- Stanford’s 2025 AI Index documented 233 AI-related incidents in 2024, a 56.4% year-over-year increase.
- AI adoption moved from 55% of organisations in 2023 to 78% in 2024, widening the gap between deployment and control maturity.
- IBM reported that 97% of organisations with breached AI models or applications lacked proper AI access controls.
Questions worth separating out
Q: How should security teams govern AI models that can call tools and access data?
A: Security teams should govern AI models as non-human identities with named owners, limited scope, short-lived credentials, and continuous authorization.
Q: Why do AI agents create accountability problems for IAM and NHI teams?
A: AI agents create accountability problems because traditional IAM proves who authenticated, while agent governance must prove what the actor did with that access.
Q: What breaks when prompt injection is not governed like an access problem?
A: The organisation may treat malicious text as a harmless message, even though it can steer an agent into exposing data or taking privileged actions.
Practitioner guidance
- Map the full AI control surface Inventory models, endpoints, datasets, vector stores, agents, and connected tools so ownership and policy boundaries are visible across the lifecycle.
- Enforce runtime policy on tool calls Require allowlists, parameter checks, and decision logging before an agent can invoke high-risk APIs, export data, or cross approval boundaries.
- Isolate untrusted context from trusted action Treat retrieved content, prompts, and external text as hostile by default, and block them from directly steering privileged actions without policy mediation.

AI security has become an identity governance problem as much as a model risk problem. Once an AI system can call tools, reach data, or trigger workflows, it is operating through entitlements that look very much like machine access. That means IAM, PAM, and NHI governance cannot stop at human users and API keys. Practitioners need to treat AI runtime permissions as a governed identity surface, with ownership, review, and revocation paths that match the actual blast radius.
A question worth separating out:
Q: Who is accountable when an AI model exposes data after a prompt attack?
A: Accountability usually sits with the team that approved the model's access model, the data owners who exposed the content, and the security function that failed to monitor the workflow. Frameworks such as NIST AI RMF and identity governance practices help define ownership, but the organisation must make tool access, logging, and review responsibilities explicit.
