A Multilevel Security (MLS) server provides MLS functionality to single-level applications running on a remote Multiple Independent Level Security (MILS) or MLS client device. More specifically, the MLS server provides a plurality of different security domains in which applications can execute. The client device executes a single-level application in a first security domain, the single-level application not natively capable of communicating with other domains. The single-level application in the first security domain sends a request to the MLS server. The MLS server receives the request, passing it to all applicable domains, including a second security domain, where it is duly executed. The MLS server then provides the results of the request execution&#x2014;if any&#x2014;back to an appropriate application on the client device. For example, the single-level application in the first security domain can display the aggregated results obtained from multiple distinct security domains, or an application running in the second security domain can display the results.
