While there are multiple security implementations in enterprise systems with distributed architecture, including authentication, authorization, and role-based access, one of the preferred and secured way of establishing the system integration is through a two-way SSL. In this concept, both the client and server shake hands by sending the expected and known Domain Name System(DNS)-named certificates (server certificate and client certificate) and confirming the system protocol before exchanging any information. Once the known system encryption is established, they start exchanging the information, which is a secured way of communication. The following diagram represents the SSL/Transport Layer Security (TLS) handshake mechanism between a client and server:
Let's review the steps involved in the SSL/TLS Handshake process here:
- ClientHello: In this stage, the client application invokes the server with the details of the highest version of SSL...
