An Act relative to cyberattack response in Massachusetts

This bill amends Massachusetts' civil defense law to explicitly address cyber threats. It adds definitions for "Critical Infrastructure" (including election systems, transportation, utilities, and water/gas/electric systems), "Cybersecurity Attack" (disrupting or stealing data), and "Cyber System" (networked hardware/software). These definitions clarify that the state's civil defense framework now covers cyberattacks targeting government systems or critical infrastructure deemed at risk by the governor. The law directly affects state agencies and the operators of essential infrastructure sectors by establishing a legal basis for response planning.
