Explanation:
Software and hardware guards allow the exchange of data between trusted(high assurance) and less trusted (low assurance) systems and environments. Forinstance, if you were working on a MAC system (working in dedicated security mode ofsecret) and you needed it to communicate to a MAC database (working in multilevelsecurity mode, which goes up to top secret), the two systems would provide differentlevels of protection. If a system with lower assurance can directly communicate witha system of high assurance, then security vulnerabilities and compromises could beintroduced. A software guard is really just a front-end product that allowsinterconnectivity between systems working at different security levels.
