Port and Protocol Tracker dashboard

The Port and Protocol Tracker tracks port and protocol activity, based on the rules set up in Configure > Content > Content Management in Enterprise Security. To edit, search for interesting_ports_lookup or use the Type dropdown menu to filter on Managed Lookup and scroll to Interesting Ports.

The lookup table specifies the network ports that the enterprise allows. From this dashboard, you can view new activity by port to identify devices that are not in compliance with corporate policy, as well as detect prohibited traffic.
