The Department of Homeland Security has recently expanded its Secure Tomorrow Series toolkit, an online resource intended to help participants recognize and mitigate cyber security threats in critical infrastructure. It is a free resource managed by the DHS’s Cybersecurity and Infrastructure Security Agency (CISA). The toolkit is designed so the user can self-facilitate topics, as it relates to their specific organization/region/sector in the critical infrastructure industry. CISA began this initiative in the wake of the COVID 19 pandemic, to provide those working in the critical infrastructure to prepare for future disrupting events like another pandemic, economic shocks, and transformative technologies.
