Identify any running AWS EC2 instances older than 180 days.
An EC2 instance is not supposed to run indefinitely and having instance older than 180 days can increase the risk of problems and issues.
Stopping and restarting instances will change the launch time and may cause temporary service disruption. Plan for maintenance windows when refreshing long-running instances.
aws ec2 describe-instances --region us-east-1 --output json --filters "Name=instance-state-code,Values=16" --query "Reservations[*].Instances[*].{Instance:InstanceId}"

{
"Instance": "i-1234567abcdefghi0"

INSTANCES, click Instances.EC2 instance. The Instance State must be 'running'.Description tab.Launch time.instance active age.AWS regions and repeat the audit process.No running EC2 instance should have a LaunchTime older than 180 days.
No specific CLI remediation command is provided. Use the console method below.
INSTANCES, click Instances.EC2 instance identified above in the audit. The Instance State must be 'running'.Actions, click Instance State, click Stop.Confirm that the instance active age is now set to today's date and time.
AWS does not enforce any default age limit on running EC2 instances.
