Coalition Information Sharing in the Age of Great Power Competition

Securing Lines of Communication (LOCs) is paramount, as every military branch has incorporated LOCs into their own domain operational art for mission success. This concept is also relevant in the cyber domain. Zero trust—as a cybersecurity paradigm—enables cyber operators to securely move critical information around the battlefield, including to and from our coalition partners and everywhere it is needed for mission success. This white paper explores the unique requirements of sharing information across the coalition and joint force cyber domain. We examine lessons learned from the Afghanistan Mission Network and how to apply those lessons to fully realize the vision of a Mission Partner Environment for the SABRE program.

• Zero Trust as an enabler will be reviewed and presented as an alternative to cross-domain solutions, using a zero trust architecture to create cyber lines of communication.
• A Mission Partner Environment requires security, accessibility, and agility, and this paper describes the benefit of decoupling those components in order to remove complexity and successfully deliver the SABRE program to the coalition warfighter.
• Finally, we'll present a model for future SABRE architectural components and deployed mission partners accessing coalition information inside the Zero Trust Exchange.
