What is the purpose of Transport Layer Security (TLS) in telecommunication?

Transport Layer Security (TLS) is primarily designed to ensure the security of information transmitted over the internet. It achieves this through encryption, authentication, and data integrity, which help protect sensitive data from interception and tampering during transmission. In essence, TLS establishes a secure channel between the communicating parties, which is vital in telecommunication, particularly when handling confidential information such as personal health data in telemental health practices.

The need for robust security measures like TLS is critical in today's digital communications landscape, given the increasing threats to data privacy and integrity. Therefore, the correct answer highlights the key role that TLS plays in safeguarding communication channels on the internet, ensuring that messages remain confidential and intact throughout their journey.
