Question : 12 of 50

Marks: +1, -0

Jane has suggested we implement full disk encryption on our laptops. Our organization, on average, loses 25 laptops per year, and currently it costs us

10,000 per laptop. The laptop itself costs

1,000, as well as $9,000 in losses from non-encrypted data being exposed. We want to keep using laptops, and have our ARO (Annualized Rate of Occurrence) stay the same. How much can the countermeasures we implement cost, for us to break even?

22500
250000
2250000
225000

Validate

Solution:

If we implemented full disk encryption, the break even point would be

225,000. We would still lose the 25 laptops per year (

1,000 per), and the cost of that loss is

25,000 per year from that ,regardless of encryption. What we would save is the 25 *

9,000 ($225,000) from the non-encrypted data exposure. This is what we can use for the encryption.
