Android Device Security – An Essential Guide For Beginner


You may love all that you can access and store with your Android phone or tablet. However, you also need the peace of mind that comes with knowing that it is all secure. Here are some very important things to think about.

Why is Android Phone/Tablet Security so Important?


Your privacy and your security should always be a key element with using any Android device. The level of awareness you have and the measures you take can prevent your personal information and data from being compromised. Sadly, too many people ignore such warnings. They assume it won’t happen to them. When it does, then they wish they had taken the given precautions.

We live in a world where we are all connected with our mobile phones and other devices. Your Android can tell people what you bought for an upcoming birthday gift surprise. It can also help you to be tracked and to identify where you have been all day. It can be unsettling to know such information about our actions are like leaving bread crumbs where we go.

In the wrong hands, that information can give a theft the window of opportunity they are looking for. They are going to focus their attention on those that don’t take security seriously. They won’t waste their time on a prospect that is difficult and time consuming. They want easy entrance, easy exit, and on to the next target.

If you have rooted your Android device, it is more vulnerable in terms of overall security. The process of rooting can weaken the level of security you have in place. Don’t worry though as there are measures you can take to improve security.



Built in Android Security Features

Security features were an important part of the discussion when the Android was still in development. From the very start, the company has recognized how important it is. They know that consumers trust their Android product to be secure. There is a system partition that protects the OS libraries, runtime for applications, and the overall framework for the applications. Safe mode setting is offered for you to use as a means of protecting your privacy on an Android device.

The Filesystem permissions ensures that someone can’t read or make changes to the files of another user. All of the Android applications are protected in this manner. The exception is if the owner of the device changes such permissions.

Android devices offer SELinux (Security-Enhanced Linux). This applies the control policies and it also helps with establishing the environment for the mandated access controls. The applications use cryptographic APIs. They offer a higher level of security than what you will gain with HTTPS and SSL.

Enhancing your Security Features

There are steps you can take to enhance your security measures on your Android device. Go to the Security page that is found in the Settings on your phone or tablet. Go through the options and set what you would like to that isn’t already automatically enabled.
In that same Security setting area, you can encrypt your Android. This will encrypt many elements of what is on that device. This includes apps you have downloaded, various settings, accounts, files, and data. With this additional level of security in place, you will need to enter a PIN when you turn your Android device on before you can access anything.

Privacy browsing is also an issue, and you want to prevent others from being able to see this too. You don’t want to leave cookies of where you have been and what you have looked at. You can use a free software tool called TOR (The Onion Router) to add this layer of privacy. It is free and it is one of the best defenses you can have against your usage being collected and analyzed.

It is recommended that you have Android Device Manager on your Android device. You can easily download it and install it. Should your device ever get lost or stolen, you may be worried about the content on it. With Android Device Manager in place, you can go online and you can erase everything from that phone or tablet.
