Denial of Service attacks are estimated to happen once every six months (twice a year) in a mid-size company. One such company, XYZ, estimates the cost of recovering from a single DoS attack to be $12000. The company decides to apply a number of controls to counter these attacks. With these controls, the frequency of successful DoS attacks against the company reduces to once a year and the cost of recovering from an instance becomes $8000. The cost of implementing these controls is $7,000 a year. From a purely financial point of view, is it worth for the company to implement these controls? Calculate the prior and post ALE and do a cost-benefit analysis to answer the question. In your answer make sure that you indicate what ARO, SLE and ALE are with and without controls. State clearly whether the company should implement the controls and explain why.
