29. Least privilege for AI agents: Identity, access, and tool binding
AI agents operating without managed identities and least-privilege role-based access controls can access or modify sensitive data, and organizations are deploying agentic capabilities faster than their identity and authorization models are evolving to safely constrain them. Best practices for designing agentic identity and authorization include establishing a unique agent principal, least-privilege roles, controlled tool access, and end-to-end auditability. Implementing these controls can help reduce the potential impact of agent actions and support accountability in the event of unexpected outcomes.
