Cybersecurity in healthcare is the protection of patient information, clinical systems, connected devices, identities, applications, and supporting infrastructure from unauthorized access, disruption, theft, or misuse. It combines technical safeguards with governance, risk management, workforce readiness, incident response, and compliance practices. Effective healthcare cybersecurity must protect sensitive data while supporting availability and the operational demands of care delivery.
