Looking for information on Protocol UDP 1993? This page will attempt to provide you with as much port information as possible on UDP Port 1993.
UDP Port 1993 may use a defined protocol to communicate depending on the application. A protocol is a set of formalized rules that explains how data is communicated over a network. Think of it as the language spoken between computers to help them communicate more efficiently.
Protocol HTTP for example defines the format for communication between internet browsers and web sites. Another example is the IMAP protocol that defines the communication between IMAP email servers and clients or finally, the SSL protocol which states the format to use for encrypted communications.

Side note: UDP port 1993 uses the Datagram Protocol, a communications protocol for the Internet network layer, transport layer, and session layer. This protocol when used over PORT 1993 makes possible the transmission of a datagram message from one computer to an application running in another computer. Like TCP (Transmission Control Protocol), UDP is used with IP (the Internet Protocol) but unlike TCP on Port 1993, UDP Port 1993 is connectionless and does not guarantee reliable communication; it’s up to the application that received the message on Port 1993 to process any errors and verify correct delivery.
Because protocol UDP port 1993 was flagged as a virus (colored red) does not mean that a virus is using port 1993, but that a Trojan or Virus has used this port in the past to communicate.

Hi Jerry,
Check out my network analyzer information and install that application. You’ll be able to look at what the packets contain that are using these ports and perhaps get a better idea of what is generating them. I wish I could tell you what port 1993 was being used for, but I’m confident if you look at the packets you’ll find out.
Do me a favor will you, when you find out, leave a comment and let everyone know what it was.
Thanks!
I have recently noticed quite some activity on our SonicWall firewall router over port 1993. This activity is coming from various IP addresses which are stationed at our remote location (through our tunnel) and are connecting to our server, which is an exchange and domain server. I’m still trying to figure out what this activity is, but this may help someone identify what it is. Unfortunately, when I do a google search for ‘Port 1993’ it returns all kinds of information about automobiles from the year 1993.
Here are the connection records on the sonicwall for this specific activity:

192.168.2.XXX is from our other location through the tunnel, and 192.168.3.102 is the domain/exchange server.
