To observe what network services are in use in a network's overall activity, which of the following dashboards in Enterprise Security will contain the most relevant data?

The Protocol Analysis dashboard is specifically designed to provide insights into the different network protocols and services being utilized within an organization's network. It focuses on analyzing and visualizing protocol usage, which is essential for understanding the overall network activity and pinpointing any anomalies or patterns associated with specific protocols.

This dashboard can help administrators monitor traffic by providing metrics such as the number of connections per protocol, the volume of data transferred, and the devices communicating, thus offering a comprehensive view of the network services in use at any given time.

While the Network Traffic Overview dashboard also addresses network activity, its primary focus is on the traffic flow and volume rather than the specific services or protocols in use. Threat Detection concentrates more on identifying potential security threats rather than providing a detailed analysis of network services. Incident Review is aimed at tracking and managing security incidents and does not primarily focus on the network services being utilized. Therefore, the Protocol Analysis dashboard stands out as the most relevant resource for observing network services and their activity.
