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

The Protocol Analysis dashboard in Splunk Enterprise Security is specifically designed to provide insights into the various network protocols that are in use, as well as how they are being utilized within the network. By focusing on network protocols, this dashboard enables users to monitor and analyze the underlying services that facilitate communication across the network. It highlights traffic patterns, protocol usage, and potential anomalies, making it essential for understanding network activities overall.

The focus of Protocol Analysis allows security professionals to correlate insights about network behaviors, identify unusual traffic that might indicate security issues, and ensure that necessary protocols are being employed effectively. This capability is crucial in maintaining a secure network environment.

In contrast, while the Intrusion Center might provide details on detected threats and alerts related to potential intrusions, it does not focus on the broader spectrum of network services and protocols in use. User Intelligence is more centered around user activities and behaviors rather than network services specifically. Threat Intelligence emphasizes external threat feeds and contextual data related to known threats, rather than providing an overview of network service activity. Thus, the Protocol Analysis dashboard is the most relevant resource for observing network services and their overall activity.
