What is a jumphost?

Answer 1

A jumphost, also known as a jump server or bastion host, is a secure intermediate server that provides controlled access to a private network from an external network. It acts as a gateway for administrators to connect to other servers within a secured environment, typically using SSH or RDP protocols. By isolating access points and enforcing strict security policies, jumphosts help mitigate risks associated with unauthorized access and enhance overall network security.
