Transport Layer Security (TLS)
Transport Layer Security (TLS) is a cryptographic protocol designed to provide secure communication over a computer network. It ensures privacy, integrity, and authentication between communicating applications, preventing eavesdropping and tampering. TLS is widely used to secure web browsing (HTTPS), email, instant messaging, and VoIP. It is the successor to Secure Socket Layer (SSL) and addresses several security vulnerabilities found in earlier versions, making it essential for protecting sensitive data transmitted over the internet.
