Bugs in network application programs can be exploited to compromise the system on which the application is running. When running these applications in an unsafe environment such as the Internet, the security concerns raised are a significant barrier to electronic commerce. In addition, these application programs (such as Web servers, mailservers, etc.) are usually too big and complex to be bug-free; trying to build security directly into these applications has proven to be very difficult. This paper demonstrates that a compartmented-mode workstation is a suitable platform to provide a secure environment that can contain most existing network applications. We describe how to wrap these applications in order to reduce the potential for a security breach without the need to rewrite the application completely. By minimizing the effort of transferring unsafe application services so that they are reasonably secure, we are able to accelerate the process of electronic commerce
