HB 1239 Maryland House of Delegates · 2026 Regular Session

Public Safety - Critical Infrastructure Protection

HB 1239 establishes a Critical Infrastructure Protection Branch within Maryland’s Coordination and Analysis Center to enhance state-wide security planning. It requires the Department of Emergency Management to coordinate responses to infrastructure attacks and sets cybersecurity reporting standards for critical infrastructure owners (like utility companies and hospitals). The bill also allows these private sector operators to join Maryland’s Information Sharing and Analysis Center to share threat data and receive security best practices. These provisions aim to improve threat identification, vulnerability assessments, and cross-sector coordination for systems vital to public safety and the economy.
