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.
Editorial analysis by NHI Mgmt Group, based on content published by AccuKnox: “AI Security: The Complete Guide to Tools, Threats & Best Practices 2026”.
By the numbers:
- AI-related incidents reached 233 in 2024, a 56.4% year-over-year increase.
- AI adoption moved from 55% of organisations in 2023 to 78% in 2024.
- Among organisations compromised in AI model or application breaches, 97% lacked proper AI access controls.
Key questions
Q: How should security teams stop prompt injection from turning into tool misuse?
A: They should enforce authorization at the tool or resource boundary, not inside the model.
Q: Why do AI applications create access control risk even when the underlying model is not compromised?
A: AI applications can still expose data when retrieval, prompts, or agent actions are allowed to operate beyond the original business need.
Q: What do security teams get wrong about AI access risk?
A: Many teams focus on the model while ignoring the identity path that reaches it.
Practitioner guidance
- Inventory AI assets and permissions Map models, endpoints, datasets, vector stores, tools and the identities they use so every runtime path has an owner and a policy boundary.
- Enforce runtime tool-call policy Require allowlisted tools, parameter validation and context isolation before an agent can act on untrusted content or external retrieval results.
- Bind AI controls to audit evidence Record policy violations, data access events and model actions in logs that GRC and SOC can use as continuous assurance evidence.
Bottom line: AI security failures now emerge when runtime context, tool permissions and data access combine inside live workflows.

Runtime enforcement is now the decisive AI governance control. AI systems fail where policy meets execution, not where policy is written. Static questionnaires and one-time assurance cannot contain prompt abuse, unsafe tool use or leakage once a model is live. The practical conclusion is that security governance has to move into the runtime path that decides whether the system may act.
A few things that frame the scale:
- AI-related credential leaks surged 81.5% year-over-year in 2025, with the surrounding AI infrastructure leaking 5x faster than core LLM providers, according to the State of Secrets Sprawl 2026.
- Only 23% of IT leaders were very confident in their organisation's ability to manage security and governance for GenAI deployments, according to a 2025 Gartner survey of 360 IT leaders.
A question worth separating out:
Q: How can organisations prove their AI controls are actually working?
A: Look for evidence that policy decisions are logged, sensitive prompts are being redacted or blocked when required, and approved AI interactions are traceable by identity and business context. Effective programmes produce audit-ready records, not just policy text. If the control cannot explain what happened in a session, it is not operational enough.
