Secure EC2 Access with SSM Session Manager and KMS

Securely connect to your EC2 instances with AWS Systems Manager Session Manager. Session Manager lets you manage your Amazon EC2 instances through an interactive one-click browser-based shell or through the AWS CLI. After the session is started, you can run bash commands as you would through any other connection type, effectively replacing the need to SSH into instances. For added security, we can enable KMS session encryption with a customer managed key. Note: SSM takes 15 minutes to find the instance, so make sure you have spare time before starting the lab!
