The Department of Defense, through DARPA, is seeking proposals for the Reasoned Cyber Visualization (RC-Vis) project, aimed at developing a semantic technology that enhances the visualization of cyber defense interactions and vulnerabilities. The primary objective is to create a modular, intermediate semantic representation of cyber defenses and known threats, enabling effective communication of cyber risks to diverse stakeholders with varying levels of technical expertise. This initiative addresses the critical need for improved data ergonomics in Security Operation Centers (SOC), facilitating better understanding and assessment of cyber security postures. The funding for Phase I is set at $250,000 for a six-month period, with proposals due by April 16, 2024. Interested parties can find more information and submit proposals through the official solicitation link at https://www.dodsbirsttr.mil/topics-app/.
