--------------------------------------- DEC(Dynamic Enhance Control) is a dynamic file access enhancement mechanism. It resolves DAC interception and sharefs security risks, precisely controlling file access via a kernel permission database, ioctl interfaces and LSM framework. DEC will bind the token ID of the application and the paths it can access. The user-level sandboxmanager module and appspawn module will configure the relevant policies. When the application accesses the control paths under the sharefs file system, DEC checks the: create, read, write, remove, rename, move, access of files by the application.
