Safe Communities Act This bill requires the Cybersecurity and Infrastructure Security Agency (CISA) to increase outreach and engagement with owners and operators of critical infrastructure. Specifically, the bill directs CISA to maintain a clearinghouse where owners and operators of critical infrastructure and other stakeholders may access security guidance, best practices, and other voluntary content developed by CISA. CISA must also issue a strategy to foster stakeholder outreach and operational engagement and establish a pilot program whereby law enforcement agencies and government officials may be trained by protective security advisors on carrying out vulnerability and risk assessments of facilities.
