Port 3372 Details
known port assignments and vulnerabilities
3 records found
||MS DTC (Microsoft Distributed Transaction Coordinator) is a Microsoft transaction processing technology. The service is installed by default in Windows 2000 and can be used by MS SQL Server and Microsoft Message Queue Server (MSMQ).
The port is vulnerable to potential DDoS attacks. A remote user may be able to crash the MS DTC service by sending 1024 bytes of random data on TCP port 3372.
If you do not need MS DTC you can set your firewall to block access to port 3372. It is possible for MS DTS to use other ports so you might need to also set your firewall to block any activity by the MS DTS service.

TCP ports use the Transmission Control Protocol. TCP is the most commonly used protocol
on the Internet and any TCP/IP network. Whereas the IP protocol deals only with packets, TCP enables two hosts
to establish a connection and exchange streams of data. TCP guarantees delivery of data
and that packets will be delivered in the same order in which they were sent.
Guaranteed communication/delivery is the key difference between TCP and UDP.
UDP ports use the Datagram Protocol, a communications protocol for the Internet network,
transport, and session layers. Like TCP (Transmission Control Protocol),
UDP is used with IP (the Internet Protocol) and makes possible the transmission of datagrams
from one computer to applications on another computer, but unlike TCP, UDP is connectionless
and does not guarantee reliable communication; it's up to the application that received
the message to process any errors and verify correct delivery. UDP is often used with time-sensitive
applications, such as audio/video streaming, where dropping some packets is preferable to waiting for delayed data.
When troubleshooting unknown open ports, it is useful to find exactly what services/processes are listening to them.
This can be accomplished in both Windows command prompt and Linux variants using the "netstat -aon" command.
We also recommend runnig multiple anti-virus/anti-malware scans to rule out the possibility of active malicious software.
