How Will App Permissions be Handled in Ubuntu Touch?
Solution 1:
This is being worked on as part of the Ubuntu App Developer Upload spec, in particular, the section on security.
This is still in early stages, but as an extract to the spec, and to provide some context:
Once an application is installed, AppArmor will provide a security sandbox to protect the user from malicious or simply broken code. To accomplish this, each application will need a properly constructed, and minimally permissive profile to restrict what their application can access on the local system.
Applications will be sandboxed via AppArmor, and permissions will be granted according to the app's AppArmor security profile.
