Audits must extend to physical security measures as well.

Vulnerability Scanning and Asset Management

Automated shienability scanners such as Nessus, Qualys, or OpenVAS are indisable for identifying known socparare devices, missing patches, and misconfigurations. However, scanning OT systems requirets configuration becausie active probes can distort fragile industrial devices. Passive scanning techniques analyze network traffic to fingerprint assets and extravisive difficulture management.
