Transport Layer Security (TLS)

Learn about transport layer security and how it secures transmission in APIs.


We have established that APIs are significant for businesses and their smooth functioning. However, to ensure their successful operation, we need a layer of security to protect data in various communication channels. The transmission of requests and subsequent responses between a client and server must be secured. Otherwise, attackers can intercept these transmissions, which can subsequently lead to information disclosure and tampering.

Assume the following simplistic view of a client-server communication that is being performed using unsecured public Wi-Fi. Without the application of any relevant security protocols, the messages we send and the API requests and responses generated are left vulnerable to any attacker over the network.
