Question 1

What is TLS?

Accepted Answer

TLS (Transport Layer Security) is the protocol that encrypts communication between your browser and websites. It is the successor to SSL. TLS 1.3 is the latest version, offering faster handshakes and stronger security than older versions.

Question 2

Why does TLS version matter?

Accepted Answer

Older TLS versions (1.0 and 1.1) have known vulnerabilities and are deprecated by major browsers. TLS 1.2 is considered secure, and TLS 1.3 provides the best security with improved performance. Using an outdated TLS version puts your data at risk.

Question 3

What is HTTP/2 vs HTTP/3?

Accepted Answer

HTTP/2 improves on HTTP/1.1 with multiplexing, header compression, and server push. HTTP/3 uses QUIC protocol (based on UDP) for faster connections and better performance on unreliable networks. Both require HTTPS (TLS) to function.
