The most common shorthand of "Normal Loss Expectancy" is NLE. The Single Loss Expectancy, Asset Value (AV), and exposure factor (EF) are related by the formula: SLE = AV * EF Introducing this conceptual breakdown of Single Loss Expectancy into Asset Value and Exposure Factor allows us to adjust the two terms independently: Asset Value may vary with inflation, market changes, etc. Knowing your Body Mass Index (BMI) puts it all in perspective. It can also convert between different units of height.

The canons are applied in order and âTo protect society, the commonwealth, and the infrastructureâ is the first canon, and is thus the most important of the four canons of The (ISC)2® Code of Ethics. We can revise our last formula to account for this: where uncertainty ranges from one for completely certain, to numbers greater than one for more uncertainty (e.g., an uncertainty of 1.5 means that the ALE might be 50 percent more than the estimate of SLE Ã ARO; an uncertainty of 2.25 means that the ALE might be more than double our estimate).Table 9.2 shows quantitative risk assessment calculations. This system takes into account global factors about a threat, such as how a vulnerability compromises an operating system and how that vulnerability affects the classic CIA principles; these are provided by a manufacturer or a CERT.

AROs can be broken down into subvalues known as Standard Annual Frequency Estimates (SAFE) and Local Annual Frequency Estimates (LAFE). Hereâs what the equation they recommend looks like: ALE = (Number of Incidents per Year) X (Potential Loss per Incident) Annual loss expectancy (ALE) is: a. I have heard many complaints about this, particularly relating to analysis of hacks and virus exposures.

In addition, explore hundreds of other calculators addressing fitness, health, math, finance, and more. If the risk has an annualized loss expectancy of £2,000, then it might not be worth spending £10,000 on new measures to prevent it. Now we can combine the monetary loss of a single incident (SLE) with the likelihood of an incident (ARO) to get the annualized loss expectancy (ALE). Counter, reduce, or manage the risk This means fixing the problem. 1] Normal Loss. This takes global facts, such as how a vulnerability compromises an operating system, accounts for classic CIA principles, and then allows each site to consider the placement and importance of that computer to the organization. You contact your accounts department for the amount of revenue you would lose (at your busiest period) if you were unable to operate for this period of time. where SLE is the Single Loss Expectancy and ARO is the Annualized Rate of Occurrence.

You need to consult both the accounts team and the individual departments to get a balanced scorecard value to represent loss. Steps for developing expectancy 1. If a threat or risk has an ALE of $5,000, then it may not be worth spending $10,000 per year on a security measure which will eliminate it. This is because it requires general statistics on external threats and their likelihood but then requires you to modify them for your own local conditions.
