An Electronic Health Record (EHR) is the digital system hospitals and clinics use to store and manage patient clinical data, such as diagnoses, medications, lab results, imaging, allergies, and care notes. In modern healthcare, the EHR is the core record that clinicians, billing teams, and support tools rely on for daily work.
From a cyber-security perspective, EHR platforms are high-value targets because they hold protected health information and can affect patient care if data is stolen, altered, or unavailable. Attackers often try credential theft, phishing, ransomware, or abuse of third-party integrations to reach EHR data. Defenders protect EHRs with strong identity controls, least-privilege access, audit logging, encryption, network segmentation, and tested backups. In AI-assisted workflows, EHR access must be tightly governed so models can draft or summarize information without exposing sensitive records or making unreviewed clinical changes.
