description: |
|
|
Ensure that your Amazon CloudFront Content Delivery Network (CDN) distributions are not using insecure SSL protocols (i.e. SSLv3) for HTTPS communication between CloudFront edge locations and custom origins.
|
|
impact: |
|
|
Insecure SSL protocols for CloudFront origins can expose sensitive data to interception and compromise, increasing the risk of man-in-the-middle attacks.
|
|
remediation: |
|
|
Configure your CloudFront distribution to enforce the use of secure SSL/TLS protocols (TLS 1.2 or higher) for all origins and disable support for outdated protocols like SSLv3 and TLS 1.0/1.1.
