Your company has been experiencing 6 incidents of theft of data per year via online intrusion. Every time this occurs, your company loses an asset value (AV) of $60,000. The Exposure Factor (EF) for this is 70%. Your company is considering purchasing an immutable backup system, or IBS (locks your backups from being tampered with, for up to 14 days after the backup) for $60,000. After installation, it is expected that your company will experience 5 incidents per year, with the same AV, and a new EF of 65%. Should your company purchase the immutable backup system? Note that all calculations can be done "by hand" (literally with pencil and paper or using a simple calculator). To receive full credit, you must show your calculation where indicated (or you will not receive any credit for your answer) and give: - Before purchase ARO = - Before purchase SLE (show your work) = - Before purchase ALE (show your work) = - ARO after purchase of the IBS = - SLE after purchase IBS (show your work) = - ALE after purchase of the IBS (show your work) = - Calculate (show your work) any savings or loss after purchase of the IBS = - Give your decision to purchase the IBS, or not to purchase it
