Not long ago I talked about how important it is to have an antivirus installed on our computer ( http://illabinformatico.blogspot.com/2009/08/migliore-antivirus-free_19.html ), today I want to tell you about the firewall.
The firewall allows us to greatly increase the security while browsing, simply monitors traffic into and out of our computer while we are connected to the internet and a good firewall allows to obtain sufficient protection from attacks from the network.
One of the best firewall on the market right now is Comodo Internet Security is completely in Italian and completely free service from a 'leader in the industry (direct link: http://download.cnet.com/3001-2239_4-10460704.html?spi=d81175b6c64f6b4c23ac9c79e75bf3ff&part=dl-6270509 ), which inside contains a virus, but is still of poor quality, and then during the 'Setup will disable it so that we do not create a conflict with those already on your computer.
To simplify the installation process after downloading the file I created this video guide that should be very clear:
Once you restart your computer easy firewall will begin to operate, is completely in Italian and not too difficult to use once you open the icon you will come to this screen:
As you can see from this screen you can check that everything is working correctly, you see the green tick. Click on Firewall
in the top right and then advanced will open this screen that allows us to access the main functions of the firewall.
If you denied (blocked) access to the Internet to program and now you want to instead allow access or vice versa, you want to allow access to a program that you had previously blocked, then go to the previous screen Network Security Policy and the window that opens, select the program or process to which we are interested from the list and click Edit .
will open another window and the top drop-down menu next to the words Action you can choose to allow or block the process or program
clicking Defense + in the top right can control the processes or programs running, going up Advanced and then on I ettings Defense + you can change the security level this function, as seen from the next screen:
clicking Other you will have access to additional features including the upgrade of the program ( Search aggiornament i) and this is the screen that you will find:
Now you should be able to use the program and its basic functions that allow us to use it quite happily.
NB The program generates many warnings that appear in the bottom right, which allows us to allow or block access to the Internet or a suspicion of running programs and processes, mainly when we installed the program recently and when we start a program for the first time.
Regarding the warnings that generates the program I recommend, if you are not experts, if not always allow you know what that process or program to prevent not to block important processes, although it would not be the right thing.
If you have questions or particular problem I will try to give an adequate response to just do this.
Here you post the link of a test that was done on the main firewall on the market so you can verifivare yourself many programs that pay benefits or in some cases they provide less protection than the free ones, because the "mercato" della sicurezza informatica è in continua evoluzione e il miglior modo per essere sempre protetti adeguatamente è quello di seguire continuamente il mercato e quindi sia i test indipendenti sia quelli ufficiali dei vari prodotti.
