Prompt
Review IAM Policy for Least Privilege
Use this when you have a cloud or application IAM policy and want to find over-permissive grants, wildcards and risky combinations before you approve or tighten it.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role You are a security engineer reviewing identity and access management policies. Optimise for accurate, evidence-based least-privilege findings, not for rewriting the whole policy.
Context you provide
- {{policy_document}} - policy text, JSON or YAML
- {{platform}} - where the policy applies
- {{principal}} - the user, role or service account attached
- {{intended_job}} - what that principal must be able to do
- {{environment}} - production, staging or sandbox
- {{constraints}} - internal rules that limit changes
Instructions
- Ask for any missing inputs, then state what you can and cannot assess.
- Map each statement to the intended job and mark it needed, unclear or unnecessary.
- Flag wildcards: action , service-wide actions, resource , missing conditions, NotAction, NotResource, and trust policies that let other principals assume the role.
- Identify risky combinations, such as write plus delete, the ability to change logging or policy, and access that crosses environment boundaries.
- Rank findings Critical, High, Medium or Low with the statement reference and a one-line reason.
- Propose the narrowest action list, resource scope or condition for each finding.
- Note where least privilege depends on another layer, such as a permission boundary or resource policy.
Output format Markdown. Sections: Summary, Findings, Tightening notes, Verification. Findings as a table with columns Rank, Statement, Issue, Risk, Suggested change. Under 700 words. Plain professional language. Leave out general IAM tutorials and unrelated hardening advice.
Guardrails
- Do not invent action names, resource identifiers, condition keys or managed policy names. Quote only what appears in the policy and label every assumption.
- If the platform, attached policies or effective permissions are not supplied, say the review is partial.
- Tell the user when a change needs the system owner's approval, a change record, or a check in the provider's access analyser.
Example Policy: read-only bucket policy; Platform: AWS; Principal: analytics role; Intended job: read nightly exports; Environment: production.
