Which diagram typically outlines both logical and physical aspects of a network?

The network diagram serves as a comprehensive illustration that typically encompasses both the logical and physical elements of a network. In this context, the logical aspects could include the arrangement of network devices, the relationships and pathways for data communication, and the protocols in use, while the physical components would denote the actual hardware such as routers, switches, servers, and the wiring connecting them.

Utilizing a network diagram is crucial for understanding how various components interact within an industrial automation and control systems (IACS) environment, especially when assessing cybersecurity risks. It allows stakeholders to visualize the integration of both the operational technology (OT) and information technology (IT) sides, aiding in identifying vulnerabilities and ensuring secure configurations.

Other choices like the network topology diagram focus mainly on the arrangement of devices and connections, often omitting details related to specific hardware or physical infrastructure. The physical infrastructure diagram centers predominantly on the hardware layout without providing insights into the data flow and interaction dynamics within the system. Meanwhile, a risk assessment matrix is primarily a tool for evaluating potential risks against various criteria and does not visually represent the network's structure or its components. Thus, the network diagram is uniquely suited for outlining the full spectrum of a network's architecture.
