Abstract
A system and method enforce file system path-based access controls in a message-based operating system. The system and method enforce a list of rules that provide a grant and an access restriction to file system paths to server applications. A path manager receives client messages marked by a kernel to indicate that the client is subject to the path-based access controls. The path manager control access to the file systems served by the server applications in response to the rules that provide grants and access restrictions. The path manager exercises that control by transmitting messages to the client that establishes privileges to systems paths through an authentication protocol.
