TL;DR: Generative AI security risk emerges when models read untrusted instructions, mix them with private context, and act through connected tools before review, according to ActiveFence. The real control problem is lifecycle governance across prompts, retrieval, memory, outputs, and agent permissions, not a single filter or scanner.
NHIMG editorial — based on content published by ActiveFence: Generative AI security risks: prompt, data, tool, and policy failure modes
Questions worth separating out
Q: How should security teams govern AI agents that can access enterprise systems?
A: Security teams should govern AI agents as non-human identities with explicit ownership, scoped privileges, and continuous monitoring.
Q: Why do generative AI tools create non-human identity risk?
A: Generative AI tools create NHI risk because they often have access to corporate data, APIs, and workflows while operating outside traditional user-account models.
Q: What breaks when prompt injection is not isolated from retrieval and tool access?
A: A malicious instruction can move from content manipulation to privileged execution.
Practitioner guidance
- Define agent-level least privilege Map each AI system to the smallest tool, data, and workflow scope it actually needs.
- Separate untrusted content from trusted instructions Treat user prompts, retrieved documents, uploaded files, and system instructions as different trust classes.
- Create a lifecycle testing loop Run pre-launch red teaming, enforce runtime guardrails, and continue post-launch evaluation after every prompt, policy, retrieval, or model update.

Generative AI security is now an identity and privilege problem, not just a model-safety problem. The article makes clear that risk appears when a model can read private context and act through tools. That means the governance question is who or what the system is allowed to impersonate, query, and execute on behalf of. For IAM and PAM teams, the control boundary has moved from login to delegation, which is why agent permissions need the same scrutiny as any other privileged workload.
A question worth separating out:
Q: Who is accountable when an AI system makes a harmful decision?
A: Accountability should follow the identity chain that authorized, configured, or triggered the action, including the human owner, the platform team, and any delegated agent or tool account. If the organisation cannot name that chain, the governance model is too weak for regulated AI use.
