Exam CISA topic 1 question 998 discussion

Encrypting device storage ensures that even if the device is lost or stolen, the data stored on it remains protected. Without the proper decryption key, unauthorized individuals cannot access the sensitive information. This is especially crucial when dealing with private health information, as it helps maintain confidentiality and complies with privacy regulations. While other options like digital certificates, remote device wipe functionality, and information security training are relevant in certain contexts, encrypted device storage directly addresses the protection of data at rest on the device, which is essential for maintaining the privacy and security of health information.
