CLOSING OPEN PORTS ON OURY COMPUTER

How to close open ports on your computer

THE PROBLEM:

What is a port?

Why would I even need to close open ports?

How can I close opened ports on my computer?

THE PRINCIPLE:

A port can be simply defined as any physical or logical connection through which a computer can connect to an external device such as a modem, printer ,tape drive or remote computer. Physical ports include

(PARALLEL; SCSI; SERIAL; USB...etc). Logical ports can be simply considered as numbers identifying the type of connection requested by a remote computer on the Internet.

Sometimes you will have to close open ports on your computer, especially port 80 (localhost) which is usually opened by some computer software like Skype or by local http/web servers like Apache. This is sometimes dangerous especially when your machine is connected to a network like internet because through open ports on your computer, hackers can use your network and even have access to your private files and folders using special software called port scanners. In fact there are many ports that are said to be very "vunerable" to penetration (port 80 is one of them as well as 3080...etc).

Read on to learn how to close any open port on your computer.

THE SOLUTION:

Closing an open port is actually quite simple. We will use the "netsh" DOS command.

SOLUTION 1) 

To close an open port manually follow the following steps:

1) Go to START -> RUN -> CMD

2) On the DOS prompt type in "netsh firewall delete portopening TCP portnumber" (replace "portnumber" with the number of the port you want to close) without the quotes. For example, if you want to close port 80 you should type this "netsh firewall delete portopening TCP 80"

3) Press Enter and youre done, you should get a message like "Command completed successfully".

NOTE: On Windows Seven you will have to run cmd.exe as administrator for it to work.

SOLUTION 2) Easiest Solution

I have written a program that does all this automatically.

3) You are asked for the number of the port you want to close, type it in then press ENTER.

5) You can close another port by pressing the "y" key or you can exit by pressing the "n" key.
