The following information, as a resource for the Samsung knox™ end user, describes various pop-up messages that may appear on the device when a security notification is issued.

To ensure that your device always has the latest security information to protect you and your data, Samsung will send security updates to your device periodically as needed. Follow the on-screen instructions to update your device.

Samsung recommends starting Automatic Updates. You need to do the following to turn on this feature.

Note: If Automatic Updates are not started, this device will display security policy update notifications after activation.

1. Select menu > Settings > Security > Security Policy Updates from the main screen.

2. When you choose to Select an update , the security policy update activates if your device is connected to a Wi- fi network.

Or if the device is connected to a 3G, 4G data network instead of Wi-Fi, the following caption is displayed to connect to the mobile network . Select OK to start the manual update via the mobile network.

3. If your security policy has been successfully updated to the latest version, you can see the following security policy update notification.

Or, if you have applied the latest security policy, you can see the following security policy update notification.

If the update fails, the following may be the case.
• Network connection error. If this is the case, try the update again after the data connection is normal.
• Limited device memory. If this is the case, delete unwanted videos, photos, or files.
• Policy file error. If this is the case, try again later.

Android Security enhancements send security reports to help Samsung identify security threats by allowing your phone to collect and send data in encrypted form. If your device is connected to a Wi-Fi network and the security report is greater than 16KB, you can see the following Send security report notification.

When you select OK, a pop-up screen titled "Privacy Policy for sending security reports" is displayed.

If you agree to all terms and conditions and choose to accept it, "Android security Enhancements" will send a security report to Samsung via Wi-Fi. In addition , the Security > Security Update Services > Send Security Report menu is automatically selected.

Your device will then automatically send security reports for threat analysis.

TIMA prevents unauthorized module mount notifications

If an unauthorized module attempts to mount, you can see the following notification:

"Your phone security has blocked operations that are not allowed. There is no need to take any further action. "

• This notification is displayed if you have installed a malicious application or virus that attempts to install a Linux core module or a modified file system.
• Another reason for this notification is that you may have modified the device's file system. Linux core modules have been blocked and will not pose a threat to the integrity of the device core. You may also need to check for malicious software or viruses on your device.

TIMA detection Disables "Android security Enhancements"

• If you install a malicious application or virus, the following notification occurs when they modify the Linux core data structure.
• Another reason is that you may have modified the core of the device.

Reboot the device to restore the "Android security enhancements" setting to normal. But that does not solve the problem of why Android security enhancements have been shut down. We recommend that you check for malicious programs, viruses, and malicious software.

TIMA detects unauthorized core modifications

If the device's security system has detected that the Linux core code has been modified since the device was opened, you will see the following notification.

This notification occurs for the following reasons:
• You have installed a malicious application or virus that modifies the core code or file system.
• You have modified the file system of the device and deleted or modified the system files.
Reboot the device to restore the core code to normal. However, it should be noted that modifications to the file system, such as the factory settings file, cannot be recovered. You may also see this error after restarting. Restarting a device does not provide a substantial remedy for changes to the core or file system. We recommend that you check for malicious programs, viruses, and malicious software.
