What does TLS stand for in the context of Care Everywhere security?

• A. Transport Layer Security.
• B. Transfer Layer Safety.
• C. Trusted Login Server.
• D. Transmission Link Security.

Answer: (A)

Protecting data as it travels between systems is the key idea. TLS stands for Transport Layer Security, the standard protocol that keeps information encrypted and intact while it moves across networks. It sits between the transport layer (how data is moved over the network) and the application layer (the software using that data), providing encryption, data integrity, and optional authentication.

During the TLS handshake, the client and server verify identities using certificates and establish a shared session key. That key is used to encrypt all subsequent data, so even if someone intercepts the traffic, the information remains unread and unaltered. This is especially important in Care Everywhere, where patient data moves between clinicians, hospitals, and Epic servers; TLS ensures confidentiality and integrity of the data in transit.

The other terms listed aren’t standard names for this security mechanism, and they don’t describe the protocol used to protect data as it’s transmitted.
