If we do not secure our mobile devices, then that can pose a serious security threat. In this article, we will discuss what the security threats of mobile devices are and how we can secure mobile devices.

1. Security vulnerabilities of mobile baseband operating systems

Most mobile devices run operating systems like Android or iOS. But, there is another operating system that runs beneath that operating system. That operating system is called the baseband operating system and is mostly proprietary to the device manufacturer.

The baseband operating system runs on its own processor and controls the device’s hardware like radio, GPS, USB ports, etc.

Attackers often exploit security vulnerabilities present in the baseband operating system of a mobile phone and perpetrate cyberattacks. For example, attackers can exploit the security vulnerabilities present in a baseband operating system to spy on a victim through the victim’s calls, text messages, etc.

So, one should regularly update the baseband operating system of one’s mobile phone. These updates are provided by the device manufacturer.

One should also use encryption to encrypt sensitive data on the phone and use application segmentation for better security.

2. Jailbreaking and rooting

Jailbreaking in iOS is the process of gaining unauthorized access or elevated privileges on a system. It basically modifies the iOS kernel and allows file system read and write access to an application.

Most of the jailbreaking tools apply some kernel patches to the iOS kernel and make some unauthorized changes to the kernel to remove the limitation and security features built by the manufacturer. And this allows the users to install additional …
