Eavesdropping $2,500 1 per quarter 4 $10,000 10. Tornado $250,000 1 per 20 years 0.05 $12,500Using the following formula to perform a cost - benefit analysis ( CBA ) , ?the company is calculating whether investing in this risk control technology ( NGFW ) , ?which costs $ 6 , 000 ?annually, is cost - effective to mitigate the attack. A positive CBA number indicates a cost - effective investment, and a negative number indicates a poor investment. CBA = ?ALE ( pre - control ) – ?ALE ( post - control ) – ?ACS Where, • ?ALE ( pre - control ) = ?the annualized loss expectancy of the risk before the implementation of the risk control • ?ALE ( post - control ) = ?the ALE examined after the risk control has been in place for a period of time • ?Annual Cost ( ACS ) = ?the annual cost of the risk control Based on the formula, what is the CBA in this scenario? Is it cost - effective for the company to invest in this security technology? Explain your reasoning.
