In the context of securing OT remote maintenance, what is the purpose of a jump host?

• A. Provide general internet access.
• B. Provide a controlled entry point to access OT systems.
• C. Allow direct access from internet.
• D. Bypass all logging.

Answer: (B)

In securing OT remote maintenance, the jump host acts as a secure gateway to reach OT systems. It provides a controlled entry point that all remote maintenance sessions must pass through, sitting between the management network (or internet-facing edge) and the OT network. This setup enforces strong authentication, often with MFA, strict access controls, and continuous session monitoring. Because every session goes through this single, hardened host, you gain a complete audit trail, can apply least-privilege access, and limit exposure of OT devices by not allowing direct connectivity from the outside. It also helps with containment and easier monitoring of actions within the OT environment. Other options don’t fit because a jump host isn’t meant to give broad internet access or permit direct internet-facing connections to OT devices, and it should not enable bypassing logs.
