This episode of Hash It Out explores ACP 240, a new standard for data centric security that enables better interoperability among coalition partners. Host Matt Howard speaks with Jimmy Lemkemeyer from Virtru and David 'Flash' Flanagan from Everfox about the evolution from network-centric to data-centric security approaches. They discuss how ACP 240, developed by the Five Eyes CCEB organization, creates a standardized framework for protecting data at the most granular level using Zero Trust Data Format (ZTDF). The conversation covers the challenges of sharing sensitive information across domain boundaries in today's dynamic mission environments, where partnerships can be temporal and ephemeral. The experts emphasize that data centric security builds upon rather than replaces network security, enabling fine-grained access control through data tagging and attribute-based policies that travel with the data. They provide practical advice for architects and program managers beginning their zero trust journey, highlighting the importance of proper data governance, tagging frameworks, and understanding that this represents a mindset shift rather than a single technology solution.
