SAMSUNG OTA SOFTWARE UPDATE

Jelly Bean

SE for Android Policy Update (SPD) Client is  a system applictation for updating the security policy files to SE for Android (Security Enhancements for Android).

 

Samsung devices protects the OS through SE for Android, which is built on the SELinux technology. Security Enhancements for Android (SE for Android) prevents apps or processes from accessing data and resources that they are not allowed to.

 

SE for Android secures the operating system as follows:

	 - Partitions the operating system into security domains. Within each domain, apps are given the minimal permissions they need to function. 

	   This contains the damage that might be caused by malicious or flawed apps, as problems in one domain do not spread into another.

	 - Uses a policy file to define which users and apps can access which files and resources. 

	   You cannot override this policy file and, for example, grant yourself access to files or resources that would otherwise be restricted. 

	   To ensure that your device uses the latest policies defined for the latest apps, enable the policy file to be updated automatically.

 

To check the policy file update settings

	The SE for Android security policy file defines which apps or processes can access device resources and data. 

	Always keep this policy file on your device up-to-date. If you are prompted to update the policy, always accept.

	 1.On your device home screen, tap the left hardware button > Settings > More (or General on some devices) > Security.
