Electronic health records are among the most important systems used in modern hospitals. They store patients' medical information, including medical history, laboratory results, and diagnoses. As healthcare institutions increasingly rely on these systems, protecting medical data from cyberattacks has become essential. Cybersecurity helps protect medical information from theft, manipulation, and unauthorized access through techniques such as encryption, multi-factor authentication, and access control systems. In addition, regular backups and continuous monitoring help reduce the risk of data loss and ensure the continuity of healthcare services. Therefore, integrating cybersecurity technologies into electronic health record systems enhances patient privacy, maintains information confidentiality, and increases trust in digital healthcare services.
