Overview
Enforce SSL-only access for your Amazon S3 buckets to enhance security and prevent insecure (HTTP) connections. This plan helps you assess, configure, apply, and validate SSL enforcement by applying a bucket policy that denies non-SSL requests. It guides you through selecting an AWS region, choosing the target S3 bucket, confirming your setup, applying the policy, and verifying enforcement.
Execution Details
1. Assessment Phase – Region and Bucket Selection
- Select AWS Region: Prompt the user to choose the desired AWS region for the operation.
- List S3 Buckets: Retrieve and display existing S3 buckets. Allow the user to select the bucket on which to enforce SSL-only access.
2. Summary Phase – Confirm Setup
- Review & Confirm S3 Configuration: Present the selected AWS region, S3 bucket name, and SSL enforcement choice. Confirm all selections before proceeding.
3. Configuration Phase – Apply SSL Enforcement Policy
- Create SSL-Only Bucket Policy: Generate a policy that denies all non-SSL requests using the
aws:SecureTransport condition. - Apply Policy to S3 Bucket: Use the AWS CLI to apply the policy to the selected S3 bucket.
4. Validation Phase – Confirm SSL Enforcement
- Verify Bucket Policy: Retrieve the bucket policy and validate that it includes the correct condition to enforce SSL-only access.
Each phase ensures your S3 bucket is securely configured to allow only encrypted (HTTPS) access, protecting your data and preventing insecure communication.
