# ONE SENTENCE SUMMARY:
The integration of IAM Access Analyzer custom policy checks into VS Code enhances security by validating IAM policies during development.
# MAIN POINTS:
1. IAM Access Analyzer custom policy checks validate policies against custom rules directly in VS Code.
2. This integration identifies overly permissive IAM policies early in the development process.
3. Proactive checks reduce misconfigurations and unintended access before deployment.
4. Developers receive fast feedback on IAM policy compliance with organizational standards.
5. Four types of checks are available: ValidatePolicy, CheckNoPublicAccess, CheckAccessNotGranted, and CheckNoNewAccess.
6. ValidatePolicy ensures alignment with AWS best practices by identifying security warnings and errors.
7. CheckNoPublicAccess verifies that resource policies do not grant public access.
8. CheckAccessNotGranted checks for disallowed IAM actions and resource ARNs in policies.
9. CheckNoNewAccess validates that policies do not grant more access than a reference policy allows.
10. Proper use of these checks enhances security while maintaining agile development practices.
# TAKEAWAYS:
1. Integrating IAM Access Analyzer in VS Code streamlines IAM policy validation.
2. Early identification of policy issues saves development time and resources.
3. The four custom checks provide comprehensive security coverage for IAM policies.
4. Adhering to AWS best practices reduces the risk of security breaches.
5. Ongoing feedback facilitates a balance between security and development agility.
