IAM Policy Troubleshooter<\/h1>\r\n

IAM Policy Troubleshooter answers one specific question: can this principal use this permission on this resource, and why. Rather than making you manually trace through every allow and deny policy attached to a resource and everything it inherits from its project, folder, and organization above it, the tool walks that entire chain for you and shows exactly which policy, at which level, produced the final answer.<\/p>\r\n

This covers running a check, then what to actually do with a result that does not match what you expected.<\/p>\r\n

Step 3: Review the Result<\/h3>\r\n

The tool shows whether that principal can use that permission on that resource, and which specific policy is responsible for the result.<\/p>\r\n\r\n\r\n\r\n

Why the Result Might Surprise You: Deny Policies and Inheritance<\/h2>\r\n

Two things explain most results that do not match what you expected from looking at a role assignment alone.<\/p>\r\n
