In a blog, the Cybersecurity and Infrastructure Security Agency (CISA) observes the recent increases in gun-related violence stress the need for the critical infrastructure community to prepare for an active shooter incident and reminds partners of its multitude of online resources and webinars that support capacity building efforts to position organizations to more effectively prepare for, mitigate the impacts of, and respond to an incident. The blog highlights CISA’s Active Shooter Preparedness web page, where stakeholders can access products, tools, videos, and translated resources. Additionally, as some of the incidents were perpetrated by an insider known to the organization, CISA provides resources to mitigate the insider threat via the Insider Threat Mitigation web page. The online training “Active Shooter: What You Can Do,” hosted by the Federal Emergency Management Agency’s Emergency Management Institute, provides information regarding the run, hide, fight approach that can assist individuals in taking appropriate action to increase the chance of survival. Finally, CISA’s Protective Security Advisors are available to provide more direct support in identifying potential vulnerabilities and corresponding protective measures.
