Shruthi J · Accepted Answer

Bastion host improves security by acting as the only public entry point to reach private EC2 instances. Instead of giving internet access to all private instances, access is routed through the bastion. Best practices: Allow SSH from trusted IPs only Use key based login Use multi-factor authentication (MFA) and IAM roles Automatically terminate idle sessions or shut down the bastion when not in use
