Abstract: The present invention is a secure Web platform (SWP) implementing a mandatory access control policy to enable a plurality of remote users operating Web browsers Internet access to CGI applications in response to HyperText Transfer Protocol (HTTP) requests. The SWP employs a computer having a compartmentalized process and file structure separated in accordance with a mandatory access control policy into an outside compartment comprising a Web server having a root directory chrooted to a directory tree containing only the minimal set of files required to interface the SWP with the Internet, and an inside compartment comprising a plurality of CGI applications having root directories chrooted to a directory separate from the Web server such that the Web server cannot communicate directly with the CGI applications, and a trusted gateway agent for communicating between the Web server and the CGI applications.
