The CIPRESS system provides security enhancements for general purpose operating systems by adding kernel level functionality for cryptographic and steganographic operations and keeping both users and application programs unmolested as far as possible. This paper describes the transparent network filtering and encryption mechanismus used in the Microsoft Windows NT implementation that allow integrated access and use control over confidential or otherwise restricted data at client systems.
