Visibility, observability, and segregation in OT/ICS

Visibility and observability are critical for securing and managing industrial OT/ICS environments. Visibility ensures that all assets, communications, and network activities are identified, while observability provides deeper insights into system behaviors, anomalies, and potential threats. Effective segregation of OT/ICS networks using VLANs, firewalls, and air-gapping minimizes the attack surface by isolating critical systems from IT and external networks. This layered approach enhances security, reduces operational risks, and ensures compliance with industry regulations.
