OT Cybersecurity Mitigations & Remediations
When a CVE (Common Vulnerabilities and Exposures) is identified, we apply structured mitigation pathways to minimize risk while maintaining operational continuity.
- Upgrading Software Version
- Updating to the latest vendor-supported software release to address known CVEs and security gaps.
- Upgrading Firmware
- Applying firmware updates to PLCs, RTUs, and field devices to patch vulnerabilities at the hardware level.
- Installing Patches
- Deploying vendor-released security patches after compatibility verification in staging environments.
- Performing Modifications in SW/HW Configurations
- Adjusting system configurations to disable vulnerable features, close unnecessary ports, or restrict access.
- Legacy Automation SW/HW Modernization
- Planning and executing upgrades for end-of-life automation systems that can no longer receive security updates.
- ICS Hardening (Defense-in-Depth)
- Employing layered security methods in system design to restrict and control access to individual products and control networks.
