Security to our data must be our number one priority.

Android Firewall is a network security term used to prevent the unwanted connection establishment. 

It is used beacuse we dont know who out there on the other side of our network is spying on our activity. So Android Firewall protects our confedentiality and integrity of valuable information from outside attacker.


It acts as shield between inside network and vast world of network outside. It decides which type of traffic to be allowed to pass and which to deny. It protect both sides of network from being defected. 

We use internet and fill so many forms or we sign in by providing our mail these all are data that can be accessed easily by a guy who codes like a pro and can use that data in anyway which is very much dangerous. without knowing the consequences we use to allow any permission asked by any application while installation which can he harmful to us.

It can be implement as hardware,software or combination of both.

Why Does Android Set not comes with Internet Firewall?

Since our home router usually by default blocks all incoming malicious websites and data.The truth is that we will never need it if we use a reputed site to download aaps and sites to do our job. So is the android manufactures dont provides us with internet firewall.

But we somehow need to access such sites without thinking more about the consequences so do we need the firewalls.
