Repudiation One other risk associated with the client side of e-commerce is the potential for a client or customer to repudiate a transaction. Obviously, if the customer truly did not initiate the transaction, the organization should not allow it. However, how does the organization decide whether a customer is really who he says he is? The answer is through authentication. The type of authentication that is used to verify the identity of the customer depends on the risk to the organization of making a mistake. In the case of a credit card purchase, there are established procedures for performing a credit card transaction when the card is not present. These include having the customer provide a proper mailing address for the purchase.

Begin8 / Network Security: A Beginner’s Guide / Maiwald / 222957-8 / 17 Blind Folio 17:414 If the e-commerce site is providing a service that requires verification of identity to access certain information, a credit card may not be appropriate. It may be better for the organization to use user IDs and passwords or even two-factor authentication. In any of these cases, the terms of service that are sent to the customer should detail the requirements for protecting the ID and password. If the correct ID and password are used to access customer information, it will be assumed by the organization that a legitimate customer is accessing the information. If the password is lost, forgotten, or compromised, the organization should be contacted immediately. Progress Check 1. The two primary differences between e-commerce services and traditional Internet services are the need for _______________ and _______________. 2. Availability is very important because it directly leads to the issue of _______________, which will help a customer determine if they will purchase from you or a competitor. CRITICAL SKILL 17.4 Implement Server-Side Security When we talk about server-side security, we are only talking about the physical e-commerce server and the Web server software running on it. We will examine the security of the application and the database in the next sections of this module. The e-commerce server itself must be available from the Internet. Access to the system may be limited (if the e-commerce server only handles a small audience) or it may be open to the public. There are two issues related to server security: The security of information stored on the server The protection of the server itself from compromise Information Stored on the Server The e-commerce server is open to access from the Internet in some way. Therefore, the server is at most semi-trusted. A semi-trusted or untrusted system should not store sensitive information.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
