Do you really need a firewall?

 

A computer as a tool has been around since the 60’s so in that regard, we can think of the internet as much younger way to connect different computers to the network than hooking up a cluster of computers in a single room. Not everyone is a super friendly online and we have known that from the start, but in recent years we are letting our guard down as there isn’t a more serious threat since 2007. Dealing with basic worms and a Trojan once in a while seems as the only thing that we do on modern day computers. Some users opt out to turn off their firewall as in their opinion, it is colliding with an important software that they need for work or it might be stopping them from playing their favorite multiplayer game.

Turned on antivirus software or the already imbedded Microsoft security made you forget about checking out if your firewall is turned on. Some programs prompt you to allow them through the firewall and some of you out there are not willing to be annoyed with prompts. User control settings are quite important as if they are turned off, then you will not able to see immediately which programs cans access your computer. Let us go through the basic concepts of the firewall and its usage.

The firewall on windows systems is used to check if you are connected to the safe network and to run a background check.  You might think that you are safe enough with all of your antivirus and antimalware software. This is not the case as the malicious programs will be able to install themselves on your computer. This way you will never know what kind of program is installed on your computer or what is more important the processes that are running currently. Some of these processes might slow down your CPU significantly without you noticing so it is advisable that you turn on the firewall.

A firewall used to play the bigger role in older Windows operating systems such as Windows ME and Windows XP. Newer operating systems such as Windows 7 and Windows 10 release their updates more often so it cannot pose as a difficult problem as on older computers. If you are on the older computer then we highly advise you to keep your firewall turned on all the time. Both private and public networks are dangerous as a hacker might be using the malicious networks to steal your data. Anytime that you see a network, which shows publicly the usage of all data; then it is the time to use the firewall to limit what kind of access the main computer is going to get. Without a firewall your computer will be much more exposed to all kinds of hacker or other malicious attacker.

Applications that act as they are useful i.e. take a form of some software that you find on the shady site or just a single wallpaper might be dangerous. Some of them can even stay hidden for a long time and activate themselves only when they take enough control of your desktop and laptop. Better to be safe and use the automated software such as windows firewall to regulate which program or other computer will be able to access your sensitive data. Multiple computers are even more prone to hacker attacks and malicious programs so it is the best idea to check if the firewall is turned on each computer separately. There is a reason because you need and admin password to change the recommended options from Windows.

Not all is that scary as firewall regulates the traffic between two computers. It is known that since the introduction of the Windows Millennium it is quite easy to connect remotely to another computer. Firewall plays an important role as it regulates the secure server which is used to establish the aforementioned connection.  This way you can be sure that the person on the other computer will not be able to damage your system file or install a malicious software. The aforementioned approach is very useful when dealing with corporate computers. An IT technician will be able to collect all of the data that he or she needs and try to fix the problem.

Regulating your network traffic is for a really advanced users and it is the best for you to let the firewall determine the best option for your PC or for your company.
