Manufacturing has become a prime target for ransomware groups, with high-profile attacks disrupting production lines and supply chains. In response, many organizations are turning to bastion hosts—hardened jump servers that act as a single, audited entry point to critical OT and IT systems. Unlike traditional VPNs, bastion hosts provide granular access control, session recording, and real-time monitoring, making them a powerful tool for preventing lateral movement by attackers. This trend reflects a broader shift toward zero-trust architectures in industrial environments, where every access request is verified and logged. For security teams in manufacturing, deploying a bastion host is no longer optional but a strategic necessity to protect against escalating cyber threats. The approach also aligns with regulatory requirements for audit trails and access management in critical infrastructure.
Ransomware attacks have surged in the manufacturing sector, targeting critical production systems. Bastion hosts, or jump servers, are emerging as a crucial security layer to isolate and audit access to sensitive industrial networks. This signal explores why this approach is gaining traction and how it fits into a broader defense-in-depth strategy.
