Which of the following best defines the 'security' of health information?

The definition of 'security' of health information is best captured by the concept of protection from unauthorized access. In the context of health information management, this means implementing measures and safeguards to ensure that sensitive patient data is kept safe from those who are not authorized to view or manipulate it. This includes various methods such as encryption, access controls, and security protocols to prevent breaches and ensure that only individuals with the appropriate permissions can access sensitive health information.

While the other aspects mentioned in the choices—such as confidentiality, integrity, and accuracy—are certainly important components of health information management, they do not specifically encapsulate the concept of security. Confidentiality refers more to the privacy of patient records, integrity relates to the accuracy and reliability of the data, and accuracy pertains to ensuring that the information reflects the true state of a patient’s health. All these elements are vital in the overall governance of health information, but the primary focus of security is to safeguard data from unauthorized access.
