Browser Security:

WWW is used for many applications today including Banking, reservation, trading,  e-commence and many such applications which require security and confidentiality of data. However, HTTP was not a secure protocol. Thus, a secure HTTP protocol was developed for applications that required secure communication channel over an unsecured network. This is called HTTP Secure and most of the contemporary browsers support this HTTPS protocol. Thus, if you are browsing a secure website then you will find https:// at the beginning. In case, you are browsing from a public computer then you must delete the contents of web cache, cookies and browsing history. All browsers provide simple way of doing this task.
