Abstract
A file system monitoring layer is positioned between a virtual file system (VFS) encryption layer and a lower level file system layer. The file system monitoring layer stores a list of applications that are allowed to access encrypted files stored in the lower level file system. The monitoring layer receives from the VFS encryption layer a request by an application to access an encrypted file. If the application is not listed on the list, the VFS encryption layer is instructed to provide the application a denial of service. If the application is listed, the VFS encryption layer is instructed to decrypt the encrypted file for the application.
