The Homeland Security Department wants to surge its ability to train critical infrastructure owners and operators on cybersecurity, according to a contracting document released Wednesday. The department is seeking a video conferencing service that it can use to provide cybersecurity webinars to 5,000 or more critical infrastructure operators simultaneously, according to the contracting document. The department officially designated election infrastructure, such as voting machines and voter rolls, critical infrastructure in January 2017, after Russian efforts to breach those systems during the 2016 elections. Homeland Security already provides training webinars on a variety of cyber topics to critical infrastructure owners as well as to state and local governments using the Adobe Connect tool, but the current system can’t serve more than 500 simultaneous attendees, the contracting document states. The division managing the prospective contract, Homeland Security’s partnership and engagement branch, is also tasked with part of the department’s outreach to election operators.
