Sensitive or confidential data must be encrypted for transmission
Communication encryption (SSL or TLS) ensures non-accessibility of data.
Any site accessible via the Internet should use the SSL protocol.
Secure Socket Layer (SSL) certificates are commonly used to secure and authenticate communications over the Internet and within corporate intranets.
When visiting a Web site that is secured by an SSL certificate, the user can see several visual cues in his Web browser confirming that SSL is enabled.
For example, the address in the browser's address bar will start with https: // for SSL-secured connections, and http: // for non-secure connections.
