The Joint Cyber Defense Collaborative (JCDC) is proud to announce its 2023 Planning Agenda—a major milestone in the collaborative’s continued evolution and maturation. Economic prosperity, national defense, and public health and safety depend on interconnected digital technologies. Widespread security flaws and configuration missteps in these technologies create opportunities for malicious actors to steal information, destroy valuable data, and cut off access to critical goods and services. JCDC’s planning agenda addresses these important and complex security challenges.
