Your security may be at risk by the permissions you grant to the applications you install. Let’s see how?

Permissions When Installing an Application

It is no secret to anyone that mobile applications are becoming more and more useful and, in some cases, necessary. With the advancement of technology, having a smart phone is easier and many already come with multiple applications for all tastes.

From them we do the bank procedures, we buy products, we book trips, we have fun with social networks and games, among many other things. However, when installing them, we pay very little attention to the permissions that they ask us to access our cell phone.

Did you know that by installing some applications you are giving your information to someone else? Below you will see some permissions that apps request to be installed:

Location: With this permission they can have detailed information about where you are through GPS and non-detailed information from the network.

Network communication: By accepting this permission, the application that you are going to install will have unlimited access to the internet.

Storage: You can modify or delete content from the USB storage, such as the photos you have saved on your cell phone.

Hardware controls: With this option, you give permission for them to access your camera to record videos or audios and take photos.

Accounts: The application will be able to obtain a list of the accounts that you have created on your device.

Messages: Here some applications will be able to read your text messages, edit them and receive the messages that come to you.

System tools: If you want to put your phone to sleep, this permission could prevent it. They can also write the synchronization settings and modify the global system, such as activating or deactivating Wi-Fi.

Programming tools: With this permission you can check access to protected content.

Network communication: If you allow them to access this permission, the application developer will be able to see the status of the network you are connected to.

Business card: This permission gives control to the contact details. They will be able to write and read contact details. They can also read your profile data, confidential information and calendar events.

Calls: This option allows application developers to read the status of the phone (whether you are talking on the phone or not), the IMEI of the device and the identifying number of the phone.

Services that cost you money: With this permission you can call phone numbers directly.

That information in the wrong hands could give you a lot of headaches. 

When you install an application, you not only get a service, you are also giving, in part, control of your cell phone, so before installing an app , check the permissions that it requests and analyze if it is worth giving them and have a total security over your device.
