A company wants to improve its security and audit posture by limiting Amazon EC2 inbound access. What should the company use to access instances remotely instead of opening inbound SSH ports and managing SSH keys?
AWS Systems Manager Session Manager is a new interactive shell and CLI that helps to provide secure, access-controlled, and audited Windows and Linux EC2 instance management. Session Manager removes the need to open inbound ports, manage SSH keys, or use bastion hosts.
Answer is B.
AWS Systems Manager Session Manager is a fully managed service that provides secure and auditable remote shell access to EC2 instances directly through the AWS Management Console, CLI, or SDKs. With Session Manager, you can access your instances without opening inbound SSH ports or managing SSH keys.
By using Session Manager, you can centrally manage access to instances, enforce fine-grained permissions using IAM policies, and record all session activity in CloudTrail for auditing and compliance purposes. It provides a secure and convenient way to access your EC2 instances without exposing them to inbound SSH traffic.
