Abstract: 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—if any—back to an appropriate application on the client device.

Abstract: A messaging system enforces compliance policies for the electronic messages. The messaging system treats a set of related messages, such as an email string between two or more people, as a message container (200) having relational references to one or more submessages (210, 212, 214). A messaging server (112) stores the messages and submessages as discrete message components within a message database (416). In addition, the messaging server (112) stores one or more compliance policies. A compliance policy describes the set of rules that apply to message components during their lifecycles and is defined in terms of a population structure, a set of rules, and a set of jobcodes. When an action occurs that involves a piece of content, the messaging system identifies the relevant compliance policy in the governance policy database (424) and applies any rules that are applicable given the population structure and jobcode.

Abstract: In an electronic mail system, a user's actions with an application for managing electronic content are monitored. Based on the user's actions and/or on the actions of other users in the system, a relevance analysis module determines a relevance to the user of a piece of electronic content based on a likelihood of interest of the electronic content piece to the user and/or a measure of a level of significance the user has to another entity associated with the electronic content piece.
