Get To Know Which Process, Software Using What TCP, UDP Ports On Your Computer

With the advancement in computer networking field and with the increase in number of systems connected together, it has become very important to track even the smallest loopholes related to the security of the system and the data. Although, there are many ways by which hackers or some other unauthorized person can attack the system and the data, but many of these have been protected by one mean or the other. Still, one of the major network security specific escapes is unauthorized opened port, through which your system can be attacked and there is a real threat for data as well. As we all know that applications and system along with the user initiated programs, always tries to sidestep the Windows Firewall in order to open a TCP/UPD port.

This is done by the applications or programs for acknowledging the incoming connections from any of the external sources. In doing so, they make the system highly prone to security attacks and malware objects and files. Although some think and advise to use Windows CLI netstat command for this but, unfortunately it doesn’t help the user in finding all the details regarding the applications and programs which have already opened ports to listen incoming calls from external sources.

So, for this you need a tool which can solve this issue for you and can avoid you from such hazardous situation. One of such tool has been launched and named as CloseTheDoor and it has been developed for specifically this purpose only. This smart tool lists down all the active as well as passive listening TCP/UDP ports over IPv4 or the IPv6 along with the complete details of the associated programs or applications. As the name suggest, it has been specifically built to close all the backdoors of the system so that any unauthenticated sources can be stopped and avoided from stealing any of the secured data or any other confidential information.


As said earlier, this smart tool displays all the information regarding the open ports and also about the program or application associated with it. It displays all the listening ports with their protocol, the process along with the complete process ID, all the associated services, etc. This really makes it very easy for identifying those specific ports which are still open and are prone to security attacks. Most important information here can be the one given in the associated services column and it can prove to be helpful while identifying all the responsible Windows services for that particular port.

Going further, it provides you many features, which can be accessed by simply right-clicking on any of the rows and then, it will show the complete context-menu to the user.


Out of these options, some can be really helpful. For eg., Locate the executable file option simply opens the folder which contains the process executable and shows it to the user. Similarly, another option named as “Terminate this process” allows the user to terminate the process directly without any delay or further intervention. Another option named as “Process services” provides all the services which are currently linked to the process. Similarly all these options, provide one or the other feature for the user.

Overall, it can prove to be a real help if you are concern about the security of your system and it is completely compatible with almost all the versions of the Microsoft Windows operating system. You may simply download it from the below given link and can try it out on your own.
