High PriorityAI-Relevant Control

Purpose

Limit user access to only the resources necessary to perform their job functions.

AI Relevance

Critical for AI systems to ensure users only have access to necessary models, data, and functions. Prevents privilege escalation in AI environments.

Implementation Guidance

Implement granular access controls, regular privilege reviews, just-in-time access provisioning, and automated privilege escalation detection.

Assessment

Review user privileges, test access controls, verify least privilege compliance, and audit privilege escalation events.
