About this tag
The jump-host tag on WindowsForum.com covers discussions about using a secure intermediary system to access isolated networks, particularly in operational technology (OT) and industrial control system (ICS) environments. Recent threads highlight how jump hosts serve as a critical mitigation layer for vulnerabilities like CVE-2025-7405 in Mitsubishi Electric's MELSEC iQ-F series, where unauthenticated remote access via Modbus/TCP can be restricted by routing traffic through a hardened jump box. Similarly, for Cisco Secure Firewall Management Center (FMC) CVE-2025-20265, a jump host can limit exposure of RADIUS-enabled management interfaces. These examples emphasize jump hosts as a practical network segmentation tool to enforce access controls and reduce attack surface in Windows-managed infrastructure.
