NRECA’s Rural Cooperative Cybersecurity Capabilities (RC3) program is working on a new do-it-yourself toolkit to assist small and medium-sized cooperatives. The RC3 Cybersecurity Tabletop Exercise (TTX) Toolkit has been through an initial round of beta testing at three cooperatives. This advisory provides an overview, and representatives from these cooperatives will be discussing what they learned from the cybersecurity incident tabletop exercise in a breakout session at TechAdvantage 2019. The complete RC3 TTX Toolkit will be made available to all cooperatives later in 2019.
