Developed a firewall that protects Android smartphones from compromised components

A threat to smartphones can also get from their components (such as touchscreen, chargers and sensors), as they have weak security settings but it seems to be a new solution for this vulnerability was found.

Every time that a user replaces a faulty component (think of the screen), the original security settings are compromised: this is because the different units of the smartphone interact with the CPU through a simple interface that does not require authentication mechanisms.

To avoid trouble in case of replacement of a component, a group of researchers expert in cyber security has developed a new firewall program that provides the level of missing protection in these situations.

This firewall, created by researchers at Ben-Gurion University of the Negev led by Dr. Yossi Oren , was “designed” to work on Android smartphones .

The risk you run when it is inserted into a compromised smartphone component: what, in fact, endangers the security of passwords and data, and in some cases it can even survive a factory reset or software updates.

The solution unearthed by Dr. Oren’s team should be appreciated by phone manufacturers, it is a firewall that can be implemented in a small chip or as an independent module connected to the CPU.

To learn more we’ll have to wait until next month when more details will be provided and demonstrations.



This person is lazy, nothing left!
