Transport Layer Security (TLS)
What is Transport Layer Security (TLS)?
Transport Layer Security is a cryptographic protocol designed to provide secure communication over a computer network. It is the successor to SSL and is most commonly used to secure web traffic (HTTPS), ensuring that data sent between a browser and a server remains private and untampered.
Why It Matters
-
It encrypts sensitive information like login credentials and credit card numbers, preventing eavesdropping by third parties.
-
TLS provides authentication, allowing users to verify that they are communicating with the intended website and not an impostor.
-
Modern web browsers require TLS for many features and will flag websites without it as “Not Secure,” which can deter visitors.
