Information System Security Risk Management Assignment Due date 20/04/2020 1. If an organization must evaluate the following three information assets for risk management, which vulnerability should be evaluated first for additional controls? Which should be evaluated last? Switch L47 connects a network to the Internet. It has two vulnerabilities: it is susceptible to hardware failure at a likelihood of 0.2, and it is subject to an SNMP buffer overflow attack at a likelihood of 0.1. This switch has an impact rating of 90 and has no current controls in place. You are 75 percent certain or the assumptions and data. - Server Websrv hosts a company Web site and performs e-commerce transactions. It has a web server version that can be attacked by sending it invalid Unicode values. The likelihood of that attack is estimated at 0.1. The server has been assigned an impact value of 100, and a control has been implanted that reduces the impact of the vulnerability by 75 percent. You are 80 percent certain of the assumptions and data. - Operators use an MGMT45 control console to monitor operations in the server room. It has no passwords and is susceptible to unlogged misuse by the operators. Estimates show the likelihood of misuse is 0.1. There are no controls in place on this asset; it has an impact rating of 5. You are 90 percent certain of the assumptions and data. X + Where R = risk rate Ly = likelihood of vulnerability occurrence 1 = impact value Rc = percentage risk already controlled U = percentage of uncertainty (100 - percentage of certainty) 2. Using the data classification scheme in this chapter, identify and classify the information in your personal computer or personal digital assistant. Based on the potential for misuse or embarrassment, what information would be confidential, sensitive but unclassified, or for public release
