The Australian Cyber Security Centre (ACSC) has released a cybersecurity guide outlining the fundamentals of cross domain solution (CDS) technologies. 

The guidance provides cross domain security principles to enable organizations to share information securely across separated networks. The guidance introduces technical and non-technical audiences to cross domain security principles for securely connecting security domains. It explains the purpose of a CDS and promotes a data-centric approach to a CDS system implementation based on architectural principles and risk management.
