AWS IAM Policy Analyzer

Understanding AWS IAM Policy Security

AWS Identity and Access Management (IAM) is the fundamental control plane for your entire AWS cloud infrastructure. A single misconfigured JSON policy can expose sensitive S3 buckets, grant unauthorized users the ability to launch expensive EC2 instances, or even lead to complete account takeover. This IAM Analyzer tool is designed to statically parse your policy documents and detect these critical vulnerabilities before they make it into production.

Common IAM Vulnerabilities Detected

• Wildcard Permissions (The * Action): Granting s3:* or iam:* is often a shortcut taken during development, but it violates the principle of least privilege. The analyzer flags overly permissive wildcard actions.
• Privilege Escalation Paths: Certain combinations of permissions, such as iam:PassRole combined with ec2:RunInstances, allow a standard user to elevate their privileges to administrator levels. This tool actively scans for known escalation vectors.
• Missing Condition Keys: Highly sensitive actions (like deleting KMS keys or assuming roles) should often be protected by aws:MultiFactorAuthPresent or source IP restrictions.

How This Tool Works (100% Client-Side Privacy)

Security tools should never ask you to compromise your security. When you paste your IAM policy JSON into this analyzer, the data never leaves your browser. There are no server-side APIs, no databases logging your policies, and no telemetry tracking the contents of your infrastructure configuration. The parsing and vulnerability detection logic runs entirely via client-side JavaScript using structural pattern matching against known AWS security best practices.
