Knox - What exactly is it?

To make personal devices for business use, fit, Samsung has developed in 2013. Knox. Knox is indeed only available on Galaxy S5, S4 and S3 as well as the grade 2 and 3 so far, but should be compatible in the future with all Samsung devices.

If the program is installed on a Samsung device, you can access its own home screen icon on Knox. By the start of the program you finally get to the secured environment of Knox. This is completely separate from the actual operating system of the smartphone. It is almost as if possessed you two smartphones in one, but they are completely different in terms of operating system, interface, home screen and launcher. Although Knox protect secret data from external attacks, but can not access the private area of ​​the phone in step backwards. let alone read or use data from this system.

What can Knox?

Knox is an operating system-matryoshka, can be stored externally and stored in the internal company data without access. Also, you can crop the Knox operating system on their own Bedüfnisse through various tools and features. So you can, for example, can automatically turn off the camera when the user enters the premises of the company. Likewise Knox protects the Firnmennetzwerk against attacks from the outside, as well as viruses and malware. These Knox has several tools:

Rooten - The crux with the Knox

When asked whether one can rooten a Knox-compatible Android device, you have to say yes and no. Technically it would be possible to root the private operating system. In the secured area of ​​Knox but which would not go; a possible root should be discussed with the administrator of the company, so as to avoid the exclusion of the device.

Conclusion

Samsung's efforts to make the relevant own devices by safety systems for the business world is, of course, a good approach and reached in terms of industrial espionage an important step. However, Knox appears to be administratively onerous by its rigid and inflexible appearing sub-operating system. it is a pity also that safety is curtailed because of the open nature of Android and Root is likely to enjoy with caution, because it restricts the user. It would be desirable that Samsung strikes a balance in this regard that although guaranteed security, freedoms of users in the same step but not circumcise.
