Fix SSL Vulnerability Part 1 of 3: SSL and TLS introduction

Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are required for secure data communication over the internet. TLS and SSL encrypt the network communication using various parameters that are decided during the initial client-server handshake. These protocols help to prevent eavesdropping and to securely identify the web server with which the connection is being made thereby making your data transactions over the internet (such as bank account access, online purchase at amazon.com, e-bay.com or other such sites, donations to an organization using credit card/bank account, household utility account access, etc) more secure.
