⚡ Key highlights:
🔹 How Policy Tester integrates with IAM simulation to validate policies before deployment
🔹 Detect misconfigurations early by running structured permission tests
🔹 Improve security reviews by ensuring least-privilege enforcement
🛠 What you’ll learn:
✅ How Policy Tester works and how to set it up
✅ Real-world examples of policy validation and debugging
✅ How to integrate it into your security workflows
💡 Why this matters:
🔸 Prevent privilege escalation before policies go live
🔸 Catch unintended access issues automatically
