As part of your CISA duties, you have been asked to look over some risk score calculations. Your organization has installed a new email server valued at $2,500. The organization plans to use it to connect its 65 client computers to the Internet for email access. Currently, this server does not have software installed for spam, content filtering, or antivirus. Your research indicates that, over a year, there is a 95% chance that the new email server will become infected. If such an infection were to occur, three-fourths of the data could be lost. Withoutantivirus, there's a good chance that a virus could bring down the network for up to four hours and divert the four-member support team from normal duties. An approved vendor has offered to sell a site license for the needed software for $175.
