description: |
|
|
|
|
Ensure AWS ACM SSL/TLS certificates are renewed at least 30 days before expiration to prevent service disruptions.
|
|
|
|
impact: |
|
|
|
|
Failure to renew certificates timely may lead to expired certificates causing service access issues or downtimes.
|
|
|
|
remediation: |
|
|
|
|
Set up Amazon CloudWatch to monitor ACM certificate expiration and automate renewal notifications or processes.
