Xenon-Based, Host Resident, Assured CDS (XEBHRA CDS)

Today, multi-domain information sharing relies on relatively static, single domain networks connected by highly assured guards, or cross domain solutions (CDS), that are trusted to move information securely between domains. To provide mobility, however, future net-centric operations require a different paradigm that moves away from current topology centric solutions. The Xenon-Based, Host Resident, Assured (XEBHRA) Cross Domain Solution (CDS) leverages the highly assured, secure Xenon hypervisor to isolate security domains from each other on an end-user's host and restrict interactions among those partitions to only those authorized. The XEBHRA CDS will reside in its own partition(s), will provide policy-based information sharing between the single domain partitions on the host, and will be controlled by a centralized, redundant, off-host management system. The innovation is to enable end-users who require cross-domain access to quickly move information between domains and, moreover, continue to operate across domains during periods when network connectivity has deteriorated or been lost completely. This functionality will be provided on the user’s device with a lower overall assurance cost than current CDS offerings.
