Samsung Knox: Understanding its role in privacy protection

It’s safe to say that privacy is one of the factors that is uppermost in our minds as we go about our day and interact with various digital services online. We’re very aware that everything we do online is tracked and collated in some form or other, and that we perhaps don’t fully appreciate the extent to which our digital footprint is tracked.

While we can and do take steps to minimise our digital footprint, devices like our phones have access to very personal and sensitive information, and we can’t help but use them to get by in this digital age. It’s nice, then, that companies like Samsung and Apple develop tools and services specifically designed to safeguard our privacy to some extent.

What is Samsung Knox?

In Samsung’s case, this takes the form of Knox, which is described as a comprehensive mobile security platform designed to safeguard user data and privacy. Unlike a third-party security app, Knox is a combined hardware-software platform that leverages both hardware and software capabilities to ensure security. Do bear in mind that Samsung also collects data from users, and that you’ll need to go over Samsung’s privacy policy to better understand the kind of data collected and what Samsung does with it.

How Samsung Knox ensures data privacy and security for your smartphone

Now that we have just what Samsung Knox is out of the way, let’s take a look at the different ways in which it helps keep the data stored on your smartphone safe and secure.

1. Secure storage and networking

Sensitive information like passwords, biometrics, PINs, and more, are securely stored and encrypted – locked by a nearly unbreakable key, so to speak – that virtually guarantees its safety. Known as the Knox Vault, this system protects your sensitive data from any kind of attack, even side-channel attacks that use unusual means of trying to gain access to your phone.

The encryption technology used is also based on hardware, which is much faster to use and also more secure than most other methods. This encryption can also work in several layers, where it’s not just individual files that are encrypted, but folders as well. Even if someone somehow copies the data or manages to gain access to the files, they won’t be able to read the contents without going through your Samsung phone’s authentication protocol.

This security extends to networking as well, where network traffic over Wi-Fi, say, especially public Wi-Fi networks, can be encrypted if you wish. Knox will also block tracking apps and logs protection history for you to refer back to if needed.

Knox also uses something called a secure container, which isolates and secures important data and credentials from even the rest of the system. This level of security might be a bit over-the-top for regular users, but enterprise customers might appreciate it.

2. Warranty bit

An interesting feature of Knox is something called Warranty Bit. It’s integrated into secure apps like Samsung Paya and your Android Work profile, apps and services which, if compromised, could lead to serious problems for you. The Warranty Bit essentially monitors the condition of the apps and can lock them down in case they’ve been tampered with or compromised in some fashion.

3. Secure boot

Like Warranty Bit, Samsung Knox also uses Secure Boot, a feature designed to ensure the integrity of your OS while it’s booting up. This checks if your firmware has been compromised, and can even detect hardware-level tampering to some extent.

4. More control over permissions

Knox integrates a separate Permission Manager service that controls how your phone’s services and files are accessed. This includes permissions for GPS, camera, and microphone, not to mention photos and other files. Users are automatically notified in real-time when any of these services are being used.

5. Miscellaneous features

While It’ll be difficult to go over every single privacy feature that Knox offers – it’s a deeply integrated and comprehensive security solution after all – here are some other important features available in Knox.

Lost devices can be easily tracked, erased, or locked as you see fit. An Auto Blocker function is available for preventing the installation and launch of suspicious apps and even updates over USB that could be malicious. Knox has protections built in against threats that come via SMS and MMS, it monitors app behaviour for unusual activity, protects the OS kernel in real-time, and so much more. Knox also offers advanced data protection and system management features for enterprise customers and applications.

Bearing in mind that Samsung’s own commitment to privacy has sometimes been known to be shaky. Knox in itself remains a powerful tool for both users and organisations alike for controlling how data is shared and secured. It’s a very capable tool, and while a little complex, it’s also one that’s worth getting to know better for long-term peace of mind and security.
