Securing USB ports in OT environments relies on three steps: mapping assets and identifying USB ports, physically isolating critical ports, and continuously monitoring deviations and anomalies. This progressive approach enables increased maturity without compromising availability.<\/strong><\/p>\n

Step 1 \u2014 Map assets and ports (visibility)<\/strong>
\nYou can only protect what you know. Seclab Xplore maps connected assets and identifies available USB ports. This visibility helps identify critical systems with exposed USB ports and prioritize protection efforts.<\/p>\n

Step 2 \u2014 Isolate critical USB ports (protection)<\/strong>
\nOnce sensitive assets are identified, Seclab Xport is deployed on the most critical systems. Physical isolation of the USB port completes the trust chain with upstream sanitization solutions such as TYREX stations: only analyzed and cryptographically signed files reach the protected system. BadUSB attacks are neutralized by design.<\/p>\n

Step 3 \u2014 Continuously detect deviations (monitoring)<\/strong>
\nSeclab Xplore provides continuous monitoring of the environment: detection of new assets, new ports, and unusual behavior. In OT, network and system changes are infrequent\u2014anomaly-based detection is more effective and generates fewer false positives than exhaustive threat hunting. Xplore can also detect whether machines have been connected to USB devices other than Seclab Xport.<\/p>\n

This step-by-step approach, enabled by the Seclab Xcore Platform (Xplore for discovery and detection, Xchange for network isolation, Xport for USB protection), allows organizations to progressively increase their cybersecurity maturity while respecting the operational constraints of industrial environments.<\/p>\n

Key takeaway<\/em><\/strong>\u00a0\u2014 Secure OT USB ports by: detecting ports (Xplore), physically isolating them (Xport + TYREX), and monitoring deviations (Xplore). This progressive approach, powered by the Seclab Xcore Platform, aligns with industrial availability constraints.<\/em><\/p><\/blockquote>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
