When a computer is connected to the Internet many connections take place by means of the TCP and UDP ports. To be able to control those connections the best idea is to have an application like Open Ports Scanner installed.
The connections by means of the TCP and UDP ports take place due to the applications and the system's tools, but malware can also take advantage of them to be able to send private data from a computer on the Internet.
Full control over your connections and open ports
Thanks to Open Ports Scanner you will be able to know at all times which ports are open, what kind of connections are taking place, the process that has opened a connection, and even the specific identification number of the IP that the port is connected to.
Another of the options offered by Open Ports Scanner is to close a port directly from the program, something that can be specially useful when you detect a port that is being used to access the computer remotely or when you aren't sure about a connection.
Therefore, if you want an application that will allow you to control which ports have been opened on your computer and by which processes, download and install Open Ports Scanner.
