Developed in the year 1996 by Netscape, SSL is a global standard security technology that safeguards the integrity and privacy of the complete data that is being transmitted in a specific session. SSL works by creating a private key for encoding the data that is being transferred between the web browser and the server. URLs that utilize the SSL connection begin with https: instead of http:, where `s’  represents the additional security.

The end users could check for the presence of SSL security by looking for a padlock in the address bar or both; a padlock and a green bar in case of extremely secure EVSSL, which would be explained in the types of SSL.
