Securing Your Website with Secure Sockets Layer (SSL)
Nowadays, people use PCs, mobile devices to perform many activities on the internet, such as webmail, online shopping, e-banking, etc. Private information is frequently being transmitted across the internet. If these sensitive data are not transferred securely, they can easily be captured or stolen by hackers without your knowledge.
SSL is the abbreviation for Secure Sockets Layer. SSL is one of the standard security technologies that protect online sensitive information such as username and password, credit card information and personal particulars when they are being sent across the network. With SSL, data is encrypted so that only the target recipient can understand it but not the others. Moreover, SSL certificates provide unique authentication which means you can be sure that you are sending information to the right server, not a fake one. All University central IT systems are SSL-enabled and enforced, e.g. AIMS, e-Portal, e-Mail, Intranet, etc., and likewise are many departmental websites with forms where users may be asked to enter their EIDs/passwords and personal particulars.
How do you know the website that you are browsing is a SSL-secured website? A SSL-secured website shows a padlock icon on the address bar of the browser. In addition, some websites use “Extended Validation Certificate” which shows a green address bar with the company name. SSL-secured websites often begin with “https://” instead of “http://”.
Usually a typical SSL certificate contains the domain name, company name, company address and the expiry date of the certificate as shown below.
