Security with HTTP

Secured HTTP
Let us discuss about what is HTTP? It is protocol to transmit the user request to remote server to open a website or web pages on internet. Its abbreviation is “Hyper Text Transfer Protocol” (HTTP) commonly used in internet browsers to open a website in the browser window. Actually when you type a website name in the browser, the HTTP protocol transfer your website name to the remote server eventually to open the web pages on your computer screen. HTTP protocol request send to the remote server through port 80 and your web address is preceded by http://websitename.

How Secure is HTTP?
Speaking In technical terms now a days HTTP protocol is not secured especially when you are making financial transactions your data can be stolen while it is transmitted to a web server. So we can conclude that sites that are using HTTP protocol are vulnerable for data theft. So, we need a alternative for HTTP to transmit the data in secured way.

You are Secure with HTTPS
HTTPSecure means HTTPS basically combination of HTTP and SSL (Secure Sockets Layer) protocol allows the user to establish a secured encrypted connection between user and the website hosted remote server. HTTPS is commonly used by websites with sensitive transactions like online payments or banking transactions or personal data. Example FACEBOOK and TWITTER social networking sites are using HTTPS protocol to keep secure their user data. When you type the name of the website https://websitename appear automatically.

HTTP use port 80
HTTPS use port 443

Warning: Don’t do any online payments or money transactions with websites without HTTPS. First check the website whether it is giving encrypted security or not, then only you proceed for transactions.
