Metron's default dashboard is intended to allow you to easily validate the end-to-end functioning of Metron with its default sensor suite. It highlights some of the useful widgets available in Kibana 4, and serves as a starting point for you to build your own customized dashboards.

The first panel in the dashboard highlights the variety of events being consumed by Metron. It shows the total number of events received, the variety of those events, and a histogram showing when the events were received.

The next set of dashboard panels shows how Apache Metron can be used to perform real-time enrichment of telemetry data. All of the IPv4 data received by Metron was cross-referenced against a geo-ip database. These locations were then used to build this set of dashboard widgets.

 

As part of the default sensor suite, YAF is used to generate flow records. These flow records provide significant visibility into which actors are communicating over the target network. A table widget displays the raw details of each flow record. A histogram of the duration of each flow shows that while most flows are relatively short-lived there are a few that are exceptionally longer in this example. Creating an index template that defined this field as numeric was required to generate the histogram.

Snort is a Network Intrusion Detection System (NIDS) that is being used to generate alerts identifying known bad events. Snort relies on a fixed set of rules that act as signatures for identifying abnormal events. Along with displaying the relevant details of each alert, the panel shows that there is only a single unique alert type; a test rule that creates a Snort alert on every network packet. Another table was created to show source/destination pairs that generated the most Snort alerts.

The Bro Network Security Monitor is extracting application-level information from raw network packets. In this example, Bro is extracting HTTP and HTTPS requests being made over the network. The panels highlight the breakdown by request type, the total number of web requests, and raw details from each web request.

Bro is extracting DNS requests and responses being made over the network. Understanding who is making those requests, the frequency, and types can provide a deep understanding of the actors present on the network.
