Our previous article, “Futureproof Your OT with Moxa’s Secure Edge-to-Core Networking“ introduced the foundations of secure and future-ready OT networks. In this follow-up, we turn the spotlight on a crucial pillar of that foundation: layered OT security. With cyberattacks on industrial environments growing more sophisticated, a multi-layered defense strategy is essential. This article examines how Moxa’s layered security approach safeguards critical assets and ensures operational continuity.

Due to the unique sensitivity of OT networks, security becomes a vital consideration in IT/OT convergence—any lack of security or insufficient protection introduces vulnerabilities into the integrated systems. The first step in building the layered defense necessary for securing industrial networks is to establish a solid foundation with secure networking devices. After these devices are deployed, OT cybersecurity solutions can be applied to protect critical assets, reinforce network perimeters, and enable thorough monitoring of security events.
