Ensure all Public Web Tier SSLTLS certificates are greater than 7 days from Expiration

Description

Public SSLTLS certificates that are used for AWS resources such as the ELB or CloudFront should always be renewed prior to expiration both as a security best practice and to ensure the reputation of the web application is not impacted by an expired certificate.

Remediation

Using the Amazon unified command line interface:

  • Request a certificate renewal from your CA, and upload the new certificate in IAM:
    aws iam upload-server-certificate –server-certificate-name <ssl_certificate_name> –certificate-body file://public_key_cert_file.pem –private-key file://my_private_key.pem –certificate-chain file://my_certificate_chain_file.pem
  • For Amazon Certificate Manager users the renewal is managed by ACM service
