Your company recently installed high-speed Internet access at the office where you work. There are 50 workstations connected to the network and the Internet. Within a week, half the computers in the office were down because of a virus that was contracted by a screen saver. In addition, network personnel from a university in England contacted the company, claiming that your computer systems were being used as a part of a DDoS attack on their Web site. By the time the damage was repaired, your company had lost about 500 work hours when employees could not use their computers. The company also lost approximately $10,000 in potential revenue by not being able to respond to purchase requests, and narrowly averted a lawsuit from the university. Take steps to prevent this from happening again:Research the price of at least three antivirus and firewall packages on the Internet and determine the most cost-effective package for the company to implement on 50 workstations.Draft a memo to the CEO with your recommendations.
