#1: If an organization has three information assets to evaluate for risk management purposes, as shown in the accompanying data, which vulnerability should be evaluated for additional controls first? Which vulnerability should be evaluated last?

• Switch L47 connects a network to the Internet. It has two vulnerabilities: (1) susceptibility to hardware failure, with a likelihood of 2, and (2) susceptibility to an SNMP buffer overflow attack, with a likelihood of 1. There is a 75 percent certainty of the assumptions and data
• Server WebSrv6 hosts a company Web site and performs e-commerce transactions. It has Web server software that is vulnerable to attack via invalid Unicode values. The likelihood of such an attack is estimated at 3. The server has been assigned an impact value of 5. There is an 80 percent certainty of the assumptions and data.

• Operators use the MGMT45 control console to monitor operations in the server room. It has no passwords and is susceptible to unlogged misuse by the operators.
