How to block incoming attacks? OR How to close opened ports?

Limit your exposure to the outside world by blocking incomming connections.


Start - Settings - Control Panel - Network Connections

Rightclick on "Local Area Network"
And go to "Properties",

In the scrollbox, Click on "Internet Protocol (IP/TCP)" and then click on the"Properties" button.

In the new window, Click on the "Advanced.."button.

Then in the other new window go to the "Options" tab, Click on"TCP/IP Filtering" and hit "Properties".

Check off "Enable TCP/IPfiltering (All adapters)" next In the Above "TCP Ports" Click on theRadio button "Permit Only" and then add in the ports that you wantpeople to be able to access...

If you're running a web server add in80, If you're running an FTP server add in 21... And so on...

Then hit"OK" And close all the other windows, And reboot when it asks you too.

Thisway you can close the ports that you do not need to be open to theoutside world.  An alternative to this tweak could be running afirewall or enabling windows built in firewall.  Please note that inorder for other computers to connect to you, for example sending a fileover AOL Instant Messenger or using Windows Messenger to send a file,make sure that the required port is not blocked on your system. Otherwise, nothing will go through.

You can leave a response, or trackback from your own site.
