When systems communicate on a network they often use one or more of the available 65,536 TCP/IP ports. https://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers
Such service names and port numbers are used to distinguish between different communication purposes and successfully remembering the association can be the key to troubleshooting a network or security issue.
Many IT professionals experience moments where they observe a port number but can’t remember the service name or what application it supports. The common next step is to leave the application you are working in and search for information about that port.
As an alternative, we created a Polarity channel that recognizes ports and notifies an analyst as to the service names associated with TCP and UDP ports.
Here is a short video of Polarity informing the user of service/port associations when they are observed in Nmap, a common port scanning and enumeration tool for which the channel was tailored.
