SSL Security

Ms. Asha Bora has done some studies on this topic. Lets see what she has to say..

In this 21st century where Internet has become the largest mode of retrieving and storing information, the security of the user information has become a necessity. To provide this security, Netscape has developed a protocol known as SSL.

What is SSL Security???

SSL is an abbreviation used for Secure Socket Layer. It is a protocol developed by Netscape for transmitting private document via Internet with full security.SSL uses a cryptographic technique that uses two keys to encrypt data:

• A public key : which is known to everyone and
• A private key or we can say it as a secret key : which is known only to the recipient of the message.

Many Websites now a days use this protocol to keep the data confidential. All the popular browsers like Internet Explorer, Netscape Browsers support SSL. It is easy to tell when a server is using SSL security. This is because URL that require an SSL connection start with “https:” instead of “http:”. “s” stands for secure connection.

We also have another protocol for transmitting data securely over the Internet; it is Secure –HTTP(S-HTTP). The only difference between the two is that SSL creates a secure connection between a client and a server, over which any amount of data can be transmitted where as we can pass only individual messages securely via S- HTTP.

Thus we can say that both the SSL and SHTTP are complementary to each other.

Now the Question arises that, when do we need SSL?

• We need SSL when we have an Online Store which accepts credit cards etc.,
• When some data is to be kept private like the account information of a customer of a bank.
• When we process some sensitive data such as address, telephone no. etc.

This was just a basic introduction to "SSL Security". In my upcoming articles I will be discussing about “How SSL Works? “And “FAQ’s on SSL “.
