Why does this matter operationally?
Security
The set of controls, protocols, and architectures that protect connectivity infrastructure from unauthorised access, interception, and disruption. In industrial and remote environments, security must account for both IT threats and the operational consequences of a compromised control path.

Network Security
Network security is the set of controls, processes, and architectures used to protect networked systems against unauthorized access, compromise, misuse, and disruption. It includes preventive, detective, and responsive mechanisms.
Concept/Framework
Network Segment
A network segment is a portion of a larger network separated for forwarding, security, management, or operational purposes. It can be defined by switching, routing, policy, or physical separation.
Concept/Framework
Network Segmentation
Network segmentation is the practice of partitioning a network into separate zones so that access, routing, and traffic flow are governed by explicit policy. The goal is to contain risk,…

OT Security
The discipline of protecting operational technology systems — industrial control systems, SCADA platforms, and the physical process equipment they control — from cyber threats, addressing the distinct availability, safety, and…
Concept/Framework
OT Visibility
The ongoing capability to observe and understand actual behavior across an operational technology environment — device communication patterns, network traffic, and deviations from established behavioral baselines — typically achieved through…

Out Of Band Management
Out Of Band Management is administrative access to a system through a separate management path that is independent of the primary production traffic path. It preserves control when the main…
