Web Security Issues at Riordan

Riordan has invested a large amount of money in their computer systems and their network. The data stored on these systems is an asset to the company. When connected to the Internet, you are exposed to many risks that can result in a loss of data, a corruption of the system or its programs, or breaches of access, all of which could be very costly to Riordan. It is imperative that Riordan address the potential threats arising from the Internet and its use.
