What does transmission security aim to protect?

Transmission security is focused on protecting electronic communications during their transmission to ensure that the data is not intercepted, modified, or compromised while being sent over networks. This is particularly relevant for electronic protected health information (ePHI), which includes sensitive patient data that must be protected under regulations such as HIPAA (Health Insurance Portability and Accountability Act). The goal of transmission security is to maintain confidentiality, integrity, and availability of ePHI as it is transmitted across networks.

This emphasis on ePHI is crucial because healthcare providers and organizations handle vast amounts of sensitive information that must remain private and secure. Ensuring that this information is protected during transmission mitigates risks of unauthorized access and potential data breaches, which could have severe implications for patient privacy and organizational compliance with legal standards.

While other options may involve aspects of communication or data security in broader contexts, they do not specifically align with the essential focus of transmission security in relation to protecting ePHI.
