What is a firewall? Do you really need one?
A firewall can be defined as a shield or a barrier that is installed to your computer or phone device from all malware threats lurking around the internet. McAfee.Com/Activate gives excellent firewall protection for securing your data in cyber-space. When the data is exchanged between your device and servers and routers; this firewall monitors all the incoming and outgoing traffic whether the transfer is safe or not. A firewall monitors the data packets and checks whether they are meeting the rules requirement or not. If not, they will be rejected from carrying the data.
Most of the Operating System has its built-in firewall which protects your device with various online dangers. But with it can’t protect your device from newly threats; so using personal firewall application is necessary for keeping your device secure from all threats.
Here are some merits of installing a Firewall in your device:
A firewall protects your device from all unauthorized remote access
One of the most dreadful things which can happen to your device is when some unauthorized person access your device remotely. You will get to know that your device is using someone else when your cursor is moving. The firewall provides you a remote desktop access disabled feature which prevents any person from accessing your device remotely.
Firewall can block email or messages which are linked with unwanted content
If your device is working on outdated OS then you might be a potential target for various malicious codes lurking around the cyberspace. But if you have a firewall in your device; it prevents all these codes from entering your network.
Blocks Trojans
A firewall is very helpful in blocking Trojans. Trojans enter in your device, steal your data files and sends them out of the device. Trojans can be very dangerous because they steal the data silently and you can’t recognize them easily. Your personal firewall blocks these Trojans from entering in your device and gives the best security to your data files.
Prevent Keyloggers
A keylogger can be defined as a spyware software used by hackers for monitoring your activities. Firewall reduces the risk of keyloggers. You can easily and freely surf the internet without compromising your data security.
Safe Gaming
Online gaming is one of the best inventions; they can be the best for spending your free time. But online gaming can also be a potential target. Many hackers connect with your network with these online games and can attack your device. Now, most of the game industries are providing a better and safe gaming interface. Firewall puts an extra layer of security in your device while playing online games. The firewall blocks the connection when finding anything suspicious. Many gamers disable their firewall while playing games because of network blocking but this is not a good practice. If your firewall is blocking your network connection simultaneously with the same game; you should uninstall that game.
It's not necessary that a firewall can be only software applications. There is a various built-in firewall in routers. Firewall can provide you a proxy server which can prevent direct contact with another network in an account for providing a safe interface to work.
