Re: Report


Computer and Mobile phone loss in NASA could cause great danger to the organization and expose the organization to all sorts of system vulnerabilities. As reported in (Melanie Pinola, 2012), 48 mobile devices were stolen between April 2009 and April 2011. A more worrying trend is the level of encryption within the organization. Only one percent of the organization is encrypted, leaving sensitive data exposed to vulnerabilities and potential losses. There is a need to review the business continuity and disaster management plan. This should be done with a deep understanding of the current problem. Currently, there are 700 laptops presently in service. These


Single Loss Expectancy (SLE)

This is a risk assessment tool, which is the monetary value experienced when there is a risk on an asset. It is a single loss that the institution will suffer.

SLE== Asset Value X Exposure Factor

$49000 X 0.99 X 700


Annualized Rate of Occurrence (ARO)

This is the projected frequency of a threat happening in a year.

48 computers lost between Apr 2009 and April 2011

Hence 24 computers lost in one year. Hence the threat on a single laptop or mobile is


Annualized Loss Expectancy (ALE)

It is based on the probability of an event occurring. Therefore, you multiply the annualized rate of occurrence (ARO) by Loss of Expectancy (SLE)


ALE=$33,957,000 X 0.034


Safeguard Value

Risk mitigation controls monetary expense. This helps determine the financial feasibility and effectiveness. The assumption is that all the proposed risk control measures are implemented correctly.

Safeguard value is based on the hardware and software cost that you invest in protecting your information in case of software theft.
