In May 2018, the Federal CIO Council Services, Strategy, and Infrastructure Committee asked ACT-IAC to evaluate the technical maturity, availability for procurement, and important issues related to potential federal agency adoption of zero trust networking (ZTN) and software defined networking (SDN). Those technologies could radically transform and improve cybersecurity and data protection and sharing. And, the Enterprise Infrastructure Solutions (EIS) contract could provide the means for agencies to acquire those capabilities. The project began with market research, presentations and demonstrations, and evaluation of the underlying trust algorithms. Completion and release of the report on this work is planned in March 2019. Future phases of work could include assessment of implementation and policy issues and pilot projects.
