What is TLS?

 

TLS stands for "Transport Layer Security." It is a protocol that provides privacy and data integrity between two communicating applications and is the most widely deployed security protocol used today. TLS is used for web browsers and other applications that require data to be securely exchanged over a network and ensures that a connection to a remote endpoint is the intended endpoint through encryption and endpoint identity verification. Client-server applications use the TLS protocol to communicate across a network in a way designed to prevent eavesdropping and tampering. There are known vulnerabilities associated with SSL 3.0/TLS 1.0 which allow adversaries to monitor/intercept traffic and decrypt secure transmissions. Updating to TLS 1.2 provides an enhanced level of encryption to protect our network.
