Transport Layer Security is a security protocol designed to improve data security over the Internet. TLS is primarily used to encrypt communications between web and servers, such as emails, messaging and voice over IP (VOIP).
TLS can help prevent data breaches and DDoS attacks through three principal elements: encryption, authentication and integrity:
- Encryption hides third-party data during transfer
- Authentication ensures the identity of the parties exchanging information
- Integrity makes sure that data has not been forged or tampered with.
TLS1.3 updates the most important security protocol on the Internet, delivering superior privacy, security, and performance. Security needs to be guaranteed when using sensitive transactions such as online shopping, payments, exchange of medical information and so forth.
TLS 1.3 provides additional privacy for data exchange, protecting the identities of users and preventing traffic analysis.
