What tool is used to encrypt and tunnel all traffic from a local machine to a remote machine to avoid detection by perimeter security controls?

• A. Bitvise
• B. Secure Pipes
• C. Traffic IQ Professional
• D. OpenSSH

Answer: (D)

The idea being tested is that encrypted tunnels can carry all of a machine’s traffic over a remote connection, wrapping it in the SSH protocol so it travels securely from local to remote. OpenSSH fits this use precisely. It’s the widely adopted, open-source implementation of SSH that provides robust tunneling capabilities, including local port forwarding, remote port forwarding, and dynamic forwarding (SOCKS). With OpenSSH, you can configure a tunnel so that traffic from the local system is sent through a remote SSH server, effectively creating an encrypted path for various services and protocols as it traverses the network. While a Windows SSH client like Bitvise can set up tunnels, OpenSSH is the standard, cross-platform tool most associated with creating these encrypted tunnels for all traffic. The remaining tools listed are not the conventional or broadly recognized solutions for establishing an SSH-based full-traffic tunnel, so they don’t fit as well for this scenario.
