Abstract

Cross-domain systems are essential for many organizations to enable information transfer for specific goals. However, ensuring data integrity and confidentiality remains a significant concern, particularly when these systems may introduce new pathways for security violations. In this thesis, we present an ontological approach to studying information flow in a cross-domain environment with domains employing a multi-level secure (MLS) environment with pre-existing trust and analyze two possible cases of cross-domain trust relationships with their impacts on the security of the domains.
