Annual loss expectancy ALE. Qualitative risk assessments are subjective! You may decide that the risks involved with an asset are too high, and the costs to protect it are too high, Calculate sle aro and ale well. That is not the case.

Admittedly, a company could choose to factor in other values, such as the sensitivity of data on the laptops, and make a judgment to purchase these controls. It can also result in the loss of future business if customers take their business elsewhere.
Once the ARO has been calculated for a risk, you can then compare it to the monetary loss associated with an asset. Acceptance makes sense if the risk and its outcomes are minimal. The ARO indicates how many times the loss will occur in a year.
The danger or probability of loss to an insurer. One considered with respect to the possibility of loss: The benefits to us are obvious, we now have a tangible or at the very least semi-tangible cost to associate with protecting the asset. Using a Poisson Distribution we can calculate the probability of a specific number of losses occurring in a given year.
Working on this scale an ARO of 0. It would be wiser to back up the data, install a firewall and anti-virus software, and run the risk that other threats will not happen. This assumes employees do not store entire databases of customer information or other sensitive data on the systems, which can easily result in much higher costs.
The text revisits this idea starting on page As a famous example, consider Coca-Cola. The organization might be considering other controls, such as a combination of hardware locks, biometric authentication, LoJack for Laptops, and more.

Dec 04, · Dr Michael Whitman uses the equation ALE = AV x EF x ARO. Often the only information available is ALE and ARO. I propose using a new equation, ALE = AVEF x.
Jan 28, · The ALE is calculated as SLE x ARO. The benefit of knowing this is to calculate the value of a control.
In general, if a control is less than the ALE, it is worth the money to invest in it. 13 rows · Answer to Using the following table, calculate the SLE, ARO, and ALE for each threat.
To calculate the ALE, use the following formula: ALE = SLE x ARO Use the ALE to identify the maximum annual budgetary amount to spend in the protection of an asset.Download
