A Chief Information Officer (CIO) asks the company's security specialist if the company should spend any funds on malware protection for a specific server. Based on a risk assessment, the ARO value of a malware infection for a server is 5 and the annual cost for the malware protection is $2500. Which of the following SLE values warrants a recommendation against purchasing the malware protection? A. $500 B. $1000 C. $2000 D. $2500
A. $500 SLE Single loss expectancy is the cost of any single loss. If a threat would cause the complete destruction of an asset, such as a stolen laptop, the SLE is simply the asset value. If a threat would merely damage an asset, such as a flood doing costly damage to a facility but leaving it repairable, the SLE is the asset value multiplied by an exposure factor representing an estimated damage percentage ARO Annual rate of occurrence is how many times you expect a given type of loss to occur a year. It doesn't need to be an integer: if your company has ten laptops stolen in the average year, the ARO is 10. If your warehouse by the river floods about every 20 years, the ARO is 0.05. ALE Annual loss expectancy is the cost per year you can expect from the threat, or the SLE × ARO. In the previous examples, 10 stolen $2500 laptops a year comes out to an ALE of $25,000, while $1,000,000 in flood damage every 20 years produces an ALE of $50,000.
