A cross-domain solution (CDS) is a set of technologies and practices designed to securely transfer and share information between different security domains or networks with different levels of classification or sensitivity. It allows organizations to exchange data while maintaining strict control over access, preventing unauthorized disclosure or leakage of sensitive information.
The primary objective of a CDS is to enable secure data transfer across various domains, such as government agencies, military branches, or different departments within an organization. It establishes mechanisms to enforce access controls, monitor and audit data transfers, and prevent data contamination or unauthorized modifications.
CDS typically employ a combination of hardware, software, and security policies to ensure the confidentiality, integrity, and availability of data during the transfer process. These solutions often utilize technologies like data diodes, secure network gateways, or specialized security appliances to enforce strict separation between the source and destination networks.
