D.
Flask

Explanation:
Flask is an operating system security architecture that provides flexible support for security policies.
The architecture was prototyped in the Fluke research operating system. Several of the Flask
interfaces and components were then ported from the Fluke prototype to the OSKit. The Flask
architecture is now being implemented in the Linux operating system (Security-Enhanced Linux) to
transfer the technology to a larger developer and user community.
