Secure remote access for OT refers to controlled and encrypted access to operational technology environments, allowing technicians, engineers, and operators to monitor and manage industrial systems remotely. As more OT environments adopt remote management, cybersecurity risks increase, making secure remote access essential.
Unlike traditional remote access solutions, secure OT access must be designed to prevent unauthorized entry while maintaining system availability. Secure methods include VPNs, zero-trust architectures, multi-factor authentication (MFA), and encrypted communication channels to prevent cyberattacks and data breaches.
Organizations implement secure remote access through strict access control policies, network segmentation, and endpoint protection. Additionally, secure remote access solutions often include real-time monitoring and audit logging to track all remote sessions. This ensures compliance with industry regulations like NIST, ISA/IEC 62443, and ensures operational continuity.
