Website Security

What are SSL and Digital Certificates?

Secure Socket Layer (SSL) is a protocol developed by Netscape in 1996 which quickly became the method of choice for securing data transmissions across the Internet. SSL is an integral part of most web browsers and web servers and makes use of the public-and-private key encryption system developed by RSA.

In order to make an SSL connection, the SSL protocol requires that a server should have a digital certificate installed. A digital certificate is an electronic file that uniquely identifies individuals and servers. Digital certificates serve as a kind of digital passport or credential which authenticate the server prior to the SSL session being established.

Typically, digital certificates are signed by an independent and trusted third party to ensure their validity. The “signer” of a certificate is known as a Certification Authority (CA), such as thawte.

An SSL Cert protects our customers' sensitive information such as their name, address, password, or credit card number by encrypting the data during transmit from their computer to your Web server.

When is SSL used?

There are two main online security problems that digital certificates solve:

  • Authentication – proving a companys (or servers) identity online and in so doing create a sense of trust and confidence in using a website.
  • Encryption - offering protection for the data submitted to a website (or between servers) so that in the event of interception, it will be unintelligible without the unique key used for decryption.
  • Solving these security problems allows online business to protect against the following scenarios:
  • Spoofing - The low cost of website design and ease with which existing pages can be copied makes it all too easy to create illegitimate sites that appear to be published by established organizations. In fact, con artists have illegally obtained credit card numbers by setting up professional-looking storefronts that mimic legitimate businesses.
  • Unauthorized Disclosure – when information is transmitted "in the clear", making it possible for hackers to intercept the transmissions and obtain sensitive information from customers.
  • Data alteration - the content of a transaction can be intercepted and altered en route, either maliciously or accidentally. User names, credit card and social security numbers as well as currency amounts, indeed any information sent "in the clear" is all vulnerable to alteration.

3-D Secure™


The 3-D Secure™ protocol was developed by Visa to improve the security of Internet payments. The protocol is offered with the service name Verified by Visa. MasterCard has also adapted a similar protocol called MasterCard SecureCode. Both are designed to allow authentication of cardholders by their Issuers at participating merchants. The objective is to benefit all participants by providing Issuers the ability to fully authenticate cardholders through the use of a password during Internet purchases, reducing the likelihood of fraudulent usage of Visa and MasterCard credit cards and improving overall transaction performance
