Firewall is a security defense software system that works to battle against malware and phishing attacks. Some OSes like the Windows have a built-in firewall to offer instant protection from threats online. However, the built-in firewall programs provide a basic level of protection and are devoid of advanced protection features and it is not scalable to customize options
If you are really in need of a robust firewall with add-on features, there are some reliable third-party firewall to deliver better protection and control. Following are the top 3 Firewall which is efficient protect your PC.
Know the need for Firewall
It is wise to know the importance of firewall. When you connect to the Internet your data can be easily accessed on both sides. If the users’ PCs are not protected, hackers find easy ways to send in malicious code to attack the PC or can find weak security holes and exploit the same, to steal data and damage the system.
The Firewall functions as a filtering system to scan the data and filter out the malicious data from entering the network. It is considered as the first line of defense.
Thus there are two broad categories of concerns that a desktop firewall helps mitigate:
1. You don’t want your data to be transmitted out by any applications, which are not authorized to collect and transmit i.e. you want full control as which application can connect to Internet and which cannot.
2. You don’t want your computer to be hacked due to any internet facing exploitable service running in your system.
The 1st requirement allows you to control that your data is not transmitted even if you have a malware active in your computer while 2nd control allows that even if you have an unpatched vulnerable service running in your system, it can’t be exploited and end up becoming an entry point for zero-day malware.
If you are concerned about above two, you definitely need a Desktop firewall.
