A widget manufacturer has installed new network servers, changing its network from a peer-to-peer network to a client/server-based network. The network consists of 300 users who make an average of $18 an hour, working on 150 workstations. Previously, none of the workstations involved in the network had anti-virus software installed on the machines. This was because there was no connection to the Internet, and the workstations didnt have floppy disk drives or Internet connectivity, so the risk of viruses was deemed minimal. One of the new servers provides a broadband connection to the Internet, which employees can now use to send and receive email, and surf the Internet. One of the managers read in a trade magazine that other widget companies have reported a 35 percent chance of viruses not infecting their network after installing T1 lines and other methods of Internet connectivity, and that it may take upwards of 150 minutes to restore data thats been damaged or destroyed. A vendor will sell licensed copies of anti-virus software for all servers and the 150 workstations at a cost of $8,700 per year. The company has asked you to determine the annual loss that can be expected from viruses, and determine if it is beneficial in terms of cost to purchase licensed copies of anti-virus software. Caculate the ARO, SLE and ALE for this risk?
