A firewall is built-in program within Windows that protects the integrity of the system from outside security threats. It is a wall that keeps outside intruders, either from the internet or another network attacking the system. In local area networking environment, a firewall protects the system from another system’s attack. It performs a similar function when an attack is launched from an internet source while browsing or surfing.
If defined in simple terms, a firewall can be a hardware, built at purpose of protecting the system, or a software within Windows environment to perform a similar role. It is highly recommended to keep your firewall status on. There is a possibility that your firewall setting is changed by any program, and if you check your firewall status on a regular basis, you can ensure it is alive all the time.

So it is wise to frequently check firewall settings on your PC. This guarantees protection of your system’s integrity. The process is very easy and not a time-consuming one at all. You just need to follow some simple steps.
