Firewalls for Android: types of applications and their capabilities

Protection from shadowing or the preservation of confidentiality is absolutely essential for all computer and mobile devices. To do this, a personal firewall is used to protect the user from unauthorized access to his data from outside. And the operating system "Android" is no exception.

Why do I need a firewall for Android?

Of course, the amount of incoming and outgoing traffic on mobile devices is much less than in Windows-systems, but even in this situation, the user is not immune from the penetration of his device a huge amount of advertising when accessing the Internet, not to mention the viruses or spyware, Stealing personal data.

Protect yourself in the simplest way by installing a firewall for the "Android" -system or any other OS. Consider the options for using the firewall for devices running Android.

Possible installation options

As in many other cases, the capabilities of the system itself are too weak (in some versions of the OS they simply do not exist). Therefore, you will need to install specialized software. You can download the application on the Play Market or find it on the same Internet.

On the other hand, installing a firewall for Android is not always as easy as it might seem at first glance. There are two options:

• Installation on devices with root-rights;
• Use of programs that do not require advanced access rights.

Let's consider both situations.

Android Firewall for Routed Devices

It is believed that installing a protective firewall on devices with root-rights looks simpler and more reliable. At least for the Android Firewall application it does. It is initially designed for installation in such systems, that is, without root-rights it will not work.

Installation is quite simple. But the program's capabilities deserve special attention. The application can not only restrict traffic or terminate some programs that try to connect to the Web spontaneously or download something from there. It can save battery power, search for applications, create up to six different user profiles, work with "white" and "black" lists, limit or allow data transfer in roaming mode, set passwords for entering programs, create usage rules or even scripts , Performed in certain moments, and much more.

Firewall for use without root-rights

However, not all devices can easily get root-rights. There are situations when it is very difficult to do this. What to use in this case? The firewall for "Android" comes without a root installation. The program is called NoRoot Firewall.

This application of its functionality, of course, looks a little weaker than the previous utility, but also knows how to make quite interesting settings, including even the creation of a list of addresses on which the denial of access can work. In addition, the program has a notification system when a process or application tries to access the Internet.

If we talk about general settings, there are no special parameters to change by default here. After the first start, we press the start button, and also tick the automatic activation at boot, we agree with the request for access to the VPN connection settings and that's all. After activating the connection in the list, you will see all the processes and applications trying to log into the network. Now only the user decides what to forbid or allow.

Thus in the list of programs it is possible to see two types of marks (squares). One is responsible for setting the parameters via Wi-Fi connections, and the second one is used to change the rules when connecting through a mobile operator network.

On the Global Rules tab, the user can block access to the Network even by a specific IP address. Finally, you can view all the events through a special magazine. By the way, the lock is useful to the owners of Chinese gadgets that spontaneously connect to the servers of this state and pass on them user information.

In general, only the two most popular programs were considered here, but on the Internet or in the same Play Market service, you can find, download and install any other firewall for Android, only before installing and using, you should read the description and pay attention to the need for root -right.
