Beware of using Credit Card on Internet

The importance of https on the internet

           

WHAT IS HTTP

·         The Hypertext Transfer Protocol (HTTP) is an application protocol for distributed, collaborative, and hypermedia information systems.

·         HTTP when you are browsing the web, it’s not secure, so someone can eavesdrop on the conversation between your computer and the web server, clients may be exchanging confidential information with a server, which needs to be secured in order to prevent unauthorized access.  

HTTPS

·         Using HTTPS, the computers agree on a "code" between them, and then they scramble the messages using that "code" so that no one in between can read them. This keeps your information safe from hackers.

·         HTTPS = HTTP + SSL 

·         HTTPS uses Secure Socket Layer (SSL) as a sublayer under its regular HTTP application layering

Beware of using Credit Card Numbers on Internet: If a website ever asks you to enter your credit card information, you should automatically look to see if the web address begins with https://. If it doesn't, there's no way you're going to enter sensitive information like a credit card number!
