What is SSL (Part-1 For Beginners)

Hi Friends. Today I am trying to write an overview of SSL (Secure Sockets Layer) .
SSL is the standard security technology for set up an encrypted link between an web server and a browser. It works on Application Layer (Seventh of Open System Interconnection Layer Model) in the Internet Protocol Suit. Secure Socket link ensures that all data passed between the web server and browsers, remain private and integral.

Now how you will know that a site is Secured by SSL at a glance ? Here is the answer:

There will appears a "S" while you browse a website using Browser

     

• You will see an Lock symbol in the browser address bar

         

Benefits:

• Authentication :- You can be sure that you are sending information to the right server and not to a offender's server.
• Data Protection :- SSL ensure that the communication between Sever and Client(your machine browser) should be through encrypted way.

Drawback:

• Cost :- Getting a SSL certificate for Business purpose can be expensive, although there have some free SSL certificate compatible of local Browser.
• Implementation hassle :- After install SSL communication requires both Servers and Client communication to do extra work in exchanging handshakes.
