OT (Operational Technology) Vulnerability Management refers to the process of identifying, evaluating, and addressing vulnerabilities in OT systems and networks. OT systems are those that control and monitor physical processes, such as manufacturing plants, power grids, and transportation systems.
OT vulnerability management involves several steps, including:
Asset Inventory: The first step is to identify and inventory all assets within the OT environment, including hardware, software, and network devices.
Vulnerability Scanning: Once assets are identified, the next step is to scan them for known vulnerabilities. Vulnerability scanners are automated tools that can identify security weaknesses in systems and applications.
Risk Assessment: The vulnerabilities identified during scanning are then assessed to determine their impact on the OT environment. This includes evaluating the likelihood of exploitation and the potential consequences of a successful attack.
Remediation: Once vulnerabilities have been identified and assessed, a plan is developed to remediate them. This may involve applying software patches, reconfiguring systems, or implementing additional security controls.
Monitoring: Finally, the OT environment is continuously monitored for new vulnerabilities and potential threats, and the vulnerability management process is repeated on a regular basis to ensure ongoing security.
Effective OT vulnerability management is critical to ensure the safety, reliability, and resilience of critical infrastructure systems.
