CVE Response

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.

1

Upgrading Software Version

Updating to the latest vendor-supported software release to address known CVEs and security gaps.

2

Upgrading Firmware

Applying firmware updates to PLCs, RTUs, and field devices to patch vulnerabilities at the hardware level.

3

Installing Patches

Deploying vendor-released security patches after compatibility verification in staging environments.

4

Performing Modifications in SW/HW Configurations

Adjusting system configurations to disable vulnerable features, close unnecessary ports, or restrict access.

5

Legacy Automation SW/HW Modernization

Planning and executing upgrades for end-of-life automation systems that can no longer receive security updates.

6

ICS Hardening (Defense-in-Depth)

Employing layered security methods in system design to restrict and control access to individual products and control networks.
