description: |
|
|
Ensure that your Amazon CloudFront distributions are using a security policy with minimum TLSv1.2 or TLSv1.3 and appropriate security ciphers for HTTPS viewer connections.
|
|
impact: |
|
|
Failing to use a security policy with a minimum of TLSv1.2 or TLSv1.3 and appropriate ciphers for HTTPS viewer connections in CloudFront can expose sensitive data to interception and reduce the overall security of your application.
|
|
remediation: |
|
|
Configure your Amazon CloudFront distributions to use a security policy that enforces a minimum of TLSv1.2 or TLSv1.3 and specifies secure ciphers for HTTPS viewer connections.
