What is one key feature of Transport Layer Security (TLS)?

One key feature of Transport Layer Security (TLS) is data encryption. TLS is primarily designed to ensure that the data transmitted over a network is secure from eavesdropping, tampering, and forgery. It achieves this by encrypting the data being sent between a client and a server, making it unreadable to anyone who might intercept the communication. This encryption process ensures that sensitive information, such as personal details, payment information, and confidential communications, remains private and secure during transmission.

In addition to encryption, TLS also provides authentication to verify the identity of the parties involved in the communication, although that is not its defining feature. While other options like packet authentication and access level restriction relate to security, they do not specifically capture the primary purpose of TLS, which is to provide a secure communication channel through encryption.
