Abstract: A new approach is proposed that contemplates systems and methods to support encryption and decryption of files including data and source code associated with a software application running in a virtual environment on a per-file basis outside of a kernel of an operating system. The proposed approach utilizes metadata of the files associated with the software application to determine the files to be encrypted and decrypted and to monitor various properties of the files including the sizes of the unencrypted files for accurate reporting of information about the files. Under such an approach, the source code of the applications are encrypted and decrypted transparently at the file level without modifying or altering any of the source code of the application, the kernel and libraries of the operating system, and/or any components which are proprietary to the virtual environment.
