TLS (Transport Layer Security)

Encryption

HTTPS SSL (Secure Sockets Layer) Man‑in‑the‑Middle (MITM) Attack Certificate Authority (CA)

Cryptographic protocol for secure transport.

Definition

TLS provides authenticated key exchange, encrypted records, and integrity protection for application-layer protocols over unreliable networks.

In plain English Cryptographic protocol for secure transport.

Why this matters

Why it matters: It mitigates passive and active adversaries, including MITM, when certificate validation and configuration are correct.

Example

Example: TLS 1.3 with AEAD ciphers and forward secrecy.
