Disable knox service. KNOX - what is it? How to remove or disable KNOX on Samsung? How does KNOX work?
Security, safety and confidentiality of user data are important attributes of the development of the IT industry. The digital market is literally flooded software products, promising a high level of protection, blocking from third party intrusions, systematic control and monitoring of the system. One such product is mobile app KNOX from Samsung, offering the user protection of his personal information, secure boot function, kernel integrity control and many other benefits. In this article I will tell you what KNOX Samsung is, how to use this application, and how to remove KNOX Samsung from your device.
KNOX is positioned by Samsung as safe environment for applications installed on your phone. This environment is implemented as a software add-on to the Android OS, which allows you to create a kind of “closed area” on your phone (the so-called “KNOX container”), where you can place the files you need. Access to this area can only be achieved by entering the appropriate password (combination of numbers, fingerprint, etc.).
The data in the said container is usually encrypted using a 256-bit encryption mechanism. You can have two identical applications on your phone: one in the public area, the second in the private area of Knox, and deleting the open version of the application will not affect the functionality of the closed application.
In addition to having the “KNOX container” function, this application allows you to control the integrity of the system kernel and its bootloader, provides a secure boot function for the OS (“Secure boot”), and offers the ability to obtain FIPS certified VPN client , allows you to remotely delete data from a lost smartphone and so on.
For KNOX to work, you need a fairly modern gadget (Galaxy S3 and newer). I also draw the attention of readers to the fact that Samsung KNOX refuses to work with rooted and custom firmware smartphones. We have explained what this KNOX application is, now we will learn how to use the development from Samsung.
How to work with KNOX Samsung
To work with the Knox functionality, you need to install the “Samsung My Knox” application on your phone, available in the Play Market (on some Samsung gadgets it is already preinstalled by the manufacturers themselves).
After installing the application and completing registration, the program will offer you to copy the applications you need to the protected KNOX area, essentially creating their protected copies.
Then you will need to configure the unlock method (password, PIN, pattern, fingerprint, two-step verification). After determining the locking method, complete the “KNOX” setup.
Launch the Samsung application on your desktop, go to its options and click “Block”. Now, to access applications hosted in the KNOX container, you will need to enter the previously specified password.
To add other applications to the KNOX container, you need to go to settings this application, and select the “Add application” option.
If you want to transfer any random file to the KNOX container, you will need to long press on this file in “My Files”, select “Options” at the top, and then “Transfer to KNOX”. Now, when you launch this application, you will find the specified file in its storage.

If this software was built into your gadget, and you decide to remove it, then take into account the possible negative consequences for the operation of the system, and act in accordance with the methods I listed above.
In contact with
In descriptions of Samsung smartphones, there is often mention of KNOX support. But sellers prefer not to provide extended information about what this function represents, limiting themselves to one line. This article will help you understand what KNOX is.
What is KNOX
KNOX is a specialized add-on for the Android OS, designed to significantly increase the level of information security on mobile device from Samsung. This system includes a set of extensions that allows you to create a secure environment on the Google platform. Among them are a special isolated zone for program execution, a 256-bit encryption mechanism and a secure boot facility.
In other words, KNOX is a protected folder in which you can install applications, transfer any files and store them there under a separate password. An application installed in this folder becomes independent from the same application installed outside the folder. So messenger app or social network, located in the KNOX folder, you can “log in” under a different account. Thus, on one smartphone you can have two Skypes with different accounts. If you delete an application outside the KNOX folder, it will remain in the folder. Access to protected applications is possible only with a password or fingerprint.
Samsung's KNOX also includes TIMA, an API that monitors the state of the operating system kernel and its integrity. On the user side, the add-on makes it possible to control application access to network resources through a secure VPN connection.
For users using Samsung smartphones in the corporate segment, this functionality provides a reliable mechanism for protecting confidential data from leakage. It has defense mechanisms on all major fronts, preventing network hacking smartphone or tablet, installation of spyware, modification of the system kernel to create “bookmarks”, as well as basic copying of files when the gadget falls into the hands of attackers.
How does KNOX work?
The KNOX complex is available on Samsung smartphones, starting with the Galaxy S3 model and newer. Theoretically, installation on other devices is possible, but no one officially guarantees this.
The main element of KNOX is a kind of virtual system Android, located “inside” the main OS. It creates a completely isolated software environment with its own encrypted file system, which cannot be accessed without KNOX. At the same time, Samsung allows the ability to read data located outside this shell without leaving it.
When the system starts, the architecture integrity protection mechanism checks the OS kernel to ensure there are no unauthorized interventions. Theoretically, this eliminates the possibility of Android being modified by third parties to create “bookmarks.” But this mechanism also has a disadvantage, which is that root access does not work correctly (if the owner requires it).
After checking the integrity of the kernel, a secure boot of KNOX occurs, the mechanism of which controls autorun. The main purpose of this function is to prevent the execution of tasks for which the user has not given permission to run in the background.
Each application inside the KNOX container can be managed by controlling the level of access. This avoids cases where a program requests permission to use functions that are not implemented in it.
Virtual private support VPN networks provides the opportunity to not worry about valuable corporate data being leaked when connecting to unprotected public and home networks.
Users of Samsung smartphones and tablets can often see the unusual abbreviation KNOX. It is especially common on forums in the firmware section for smartphones. What does this abbreviation mean?
What is KNOX?
Samsung's KNOX is a unique solution that enhances security at both the hardware and application levels. KNOX allows you to implement a kind of container, which in turn creates a separate environment for work, data storage, and approved applications. The bottom line is that the data that is inside this storage is reliably protected from hacking attempts, from phishing, from malware, etc. Moreover, you can count on security even if the device is lost.
KNOX was first announced in 2013 and began to be installed on devices starting with the S3 model. Because KNOX is present on Google Play Store, this, in theory, suggests that it can be installed on earlier devices of the Korean company.
How does KNOX work?
KNOX, as we have already found out, allows you to create a container inside an existing operating room Android systems. In fact, a second own operating system, which has its own home screen, widgets and even its own application installation system. All data that is installed inside the container is in no way associated with other applications or files that are stored outside the container. Moreover, in some cases, the user can provide access to protected applications to read data outside the container, for example, if an address book is needed.
All files inside the container are encrypted using Advanced Encryption Standard (AES) with a 256-bit key, and in addition, the system can be configured to use VPN for each application.
Additionally, three functions have been built into KNOX:
- TIMA (TrustZone-based Integrity Measurement Architecture) integrity verification system
- Improving overall Android security
These systems generally ensure that data remains secure. If certain changes threaten, the system may even turn off the device for security purposes.
In short, if you need increased security for storing data, KNOX can be a great solution for you.
Every second smartphone user puts a password on the unlock screen so that a stranger cannot view his personal data if the device falls into his hands. It's quite reliable. Only we do not take into account that most of the user’s data is mainly stored on a memory card, which can be physically removed and unlimited access to the data can be obtained.
Another disadvantage of a password on the unlock screen is its visual accessibility. Anyone nearby can simply see you enter a password or pattern and remember it, and subsequently use your smartphone. There is also no guarantee that personal data is protected from malware.
I can say about myself that every time I enter a password or graphic key annoying, and over time I still removed the secure screen lock.
However, now I know how to protect personal files on Android.
I started using Samsung program KNOX, which came installed as standard on my Galaxy S4. Those Samsung owners Those who do not have this program installed can install it from the Galaxy Apps store.
Now let's move on to the advantages of Samsung KNOX.
The main function of the program is the ability to create another user account, which contains a separate list of applications and a separate part is highlighted internal memory. The fact is that this allocated memory area cannot be detected. It becomes visible only if you log into your KNOX account on your phone. Data can be moved from personal mode to private mode. IN private mode there are no options for transferring a file either via wireless networks and through a computer. Even knowing the password from Samsung account The KNOX program will not allow you to transfer data to another device.
Remember that in addition to storing personal Samsung files KNOX has its own gallery, calendar, contacts, etc. In fact, you have another working smartphone in your hands.
Thus, any documents located on the phone are complete safety. I’ll also add that the KNOX account is located only in the internal memory, and at the same time, it is carefully hidden, so it is almost impossible to remove files.
In the video you will clearly see how to protect personal files on a smartphone with using Samsung KNOX.
