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

• A. Improve network routing efficiency
• B. Provide secure communication over a network
• C. Store user credentials locally
• D. Compress data to reduce bandwidth

Answer: (B)

The main point of TLS is to enable secure communication over a network. It does this by creating an encrypted and authenticated channel between two endpoints. Through a handshake, the parties verify each other’s identities with certificates, agree on cryptographic keys, and establish protections that keep data private in transit, detect any tampering, and confirm who you’re talking to. This combination of confidentiality, integrity, and authenticity is what makes TLS essential for securing protocols like HTTPS. It isn’t about routing efficiency, storing credentials locally, or compressing data, which are separate concerns.
