Bastion Host
A Bastion Host is like a security checkpoint or gateway computer that protects an organization's internal network from outside threats. Think of it as a secure entrance lobby in a building - everyone must pass through this checkpoint before accessing anything inside. It's usually the only computer that can be accessed from the internet, and it has extra security measures in place. Companies use Bastion Hosts to safely manage their cloud resources and internal systems while keeping hackers out. This concept might also be called a "Jump Server" or "Jump Box" in job descriptions.
