IAM Policy
Understanding IAM Policies
ℹ️ What is an IAM Policy? An IAM Policy is a JSON document that defines permissions and access controls for AWS resources. These policies:
- Define precise permissions for AWS services and resources
- Can be attached to IAM Users, Groups, and Roles
- Follow the principle of least privilege
- Enable fine-grained access control
Policy Assignment
ℹ️ How Policies Work IAM Policies provide the authorization framework by:
- Defining allowed and denied actions
- Specifying resource-level permissions
- Supporting both AWS managed and customer managed policies
- Enabling conditional access based on tags, time, or location
🔒 Security Best Practices When working with IAM Policies:
- Use AWS managed policies when possible
- Create custom policies only when necessary
- Regularly review and audit policy assignments
- Implement least privilege access
💡 Pro Tip Use the AWS Policy Simulator to test and validate your IAM policies before implementation
