subject: The Challenges For Data Security Faced by Firms [print this page] Clearly there are several challenges faced by firms, when attempting to ensure internet security. The most simple to do, is to ensure that the firm's customers who use their online services are educated in internet security. For example, almost all banks have warnings on their websites. They have messages saying, "Remember NatWest will never ask you for your PIN or Password in an e-mail. The website also offers other information to customers with regards to staying safe online. It warns about relying on the padlock icon at the bottom of the window when accessing a website, to judge whether it is safe or not. This icon alone is not proof of security, customers must also look at the address bar at the top of the window, 'http://' is not a secure site, whereas 'https://' is. An http website uses a plain text system socket, this is the easiest form of text to transfer, as it is used by almost all applications on a computer, however, it is also easily read by hackers. Therefore, the https system was developed. The data is encrypted by either the Secure Socket Layer (SSL) protocol or Transport Layer Security (TLS) protocol. This ensures that the customer has some protection from people trying to gain access to sensitive data; this encryption is known as cryptography.
