- 1. Introduction to FAIR Factor Analysis of Information Risk by Patrick Florer, Principal Consultant April 28, 2010 © 2010 Aliado Accesso LLC
- 2. Let’s talk about risk © 2010 Aliado Accesso LLC
- 3. Factor Analysis of Information Risk (FAIR) Definition of Risk risk (rĭsk) [French risque, from Italian risco, rischio.] 1. The possibility of suffering harm or loss; danger. 2. A factor, thing, element, or course involving uncertain danger; a hazard. 3. The danger or probability of loss to an insurer. 4. The amount that an insurance company stands to lose. 5. The variability of returns from an investment. 6. The chance of nonpayment of a debt. 7. One considered with respect to the possibility of loss: a poor risk. from The American Heritage® Dictionary of the English Language, Fourth Edition. Copyright © 2006, 2000 by Houghton Mifflin Company © 2010 Aliado Accesso LLC
- 4. Factor Analysis of Information Risk (FAIR) Definition of Risk risk: Risk is the possibility of suffering harm or loss. It is the potential for realizing unwanted negative consequences of an event. It refers to a situation where a person could do something undesirable or a natural occurrence could cause an undesirable outcome, resulting in a negative impact or consequence. from An Introduction to the OCTAVESM Method by Christopher Alberts and Audrey Dorofee, Software Engineering Institute, Carnegie Mellon University; last updated January 30, 2001 © 2010 Aliado Accesso LLC
- 5. Factor Analysis of Information Risk (FAIR) Definition of Risk risk: The probable frequency and probable magnitude of future loss. from the Factor Analysis of Information Risk (FAIR), ©2008 Risk Management Insight, LLC © 2010 Aliado Accesso LLC
- 6. Factor Analysis of Information Risk (FAIR) IT – Related Risk The net mission impact considering: 1. The probability that a particular threat-source will exercise accidentally trigger or intentionally exploit) a particular information system vulnerability 2. The resulting impact if this should occur. IT-related risks arise from legal liability or mission loss due to: 1. Unauthorized (malicious or accidental) disclosure, modification, or destruction of information 2. Unintentional errors and omissions 3. IT disruptions due to natural or man-made disasters 4. Failure to exercise due care and diligence in the implementation and operation of the IT system. from NIST Special Publication 800-30 © 2010 Aliado Accesso LLC
- 7. And now, let’s talk briefly about a few other concepts that will be important in helping you to understand FAIR © 2010 Aliado Accesso LLC
- 8. Factor Analysis of Information Risk (FAIR) Possibility vs. Probability What’s the difference? Possibility – “capable of happening, existing, or being true without contradicting proven facts, laws, or circumstances known to be true” Probability – “The likelihood that a given event will occur” And, in statistics - “A number expressing the likelihood that a specific event will occur, expressed as the ratio of the number of actual occurrences to the number of possible occurrences” (All quotes from the American Heritage Dictionary of the English Language, Fourth Edition) © 2010 Aliado Accesso LLC
- 9. Factor Analysis of Information Risk (FAIR) Possibility vs. Probability Possibility – a set of outcomes, sometimes binary – yes or no – something that could happen. Understanding the possibilities does not necessarily require data, just a knowledge of possible outcomes Probability – a mathematical calculation with a result where 0 <= P(x) <= 1 Probability is sometimes expressed as a percentage (0 – 100%) , or as an odds ratio (3 out of 4) Probability calculations require data – either actual/historical or estimates © 2010 Aliado Accesso LLC
- 10. Factor Analysis of Information Risk (FAIR) Possibility vs. Probability Using a coin as an example … The possibilities are … The probabilities are … Knowing the possibilities does not, in any way, allow you to predict whether the coin will come up heads on the next toss, or on any toss. Knowing the probabilities does not allow you to do this, either, but it does allow you to predict the number of heads that will come up if you toss the coins a large number of times. © 2010 Aliado Accesso LLC
- 11. Factor Analysis of Information Risk (FAIR) Precision vs. Accuracy What’s the difference? Precision – “the ability of a measurement to be consistently reproduced” Accuracy – “the ability of a measurement to match the actual value of the quantity being measured” (All quotes from the American Heritage Dictionary of the English Language, Fourth Edition) © 2010 Aliado Accesso LLC
- 12. Factor Analysis of Information Risk (FAIR) Precision vs. Accuracy Why does this matter? Precise Accuracy – This would be great, but it is often not achievable. Precision – For example, my watch may run 10 minutes slow with great precision. If you ask me the time, I may tell you the wrong time. Accuracy – My watch runs slow at times and fast at times. If you ask me the time, I will likely say – it’s about 10:00 o’clock – imprecise, perhaps, but good enough for the circumstances. © 2010 Aliado Accesso LLC
- 13. Factor Analysis of Information Risk (FAIR) Qualitative vs. Quantitative Methods What’s the difference? Qualitative – low, medium, high, or red, yellow, green, or 1 – 5, etc. Good for some types of quick assessments and quick prioritizations. But - Variability in assessment is a problem, both between different assessors and with the same assessor over time. Qualitative assessments cannot be manipulated arithmetically. Qualitative scales are problematic near the boundaries. Most of the time, when making a qualitative assessment, the assessor has a number in mind anyway – why not just use the number? © 2010 Aliado Accesso LLC
- 14. Factor Analysis of Information Risk (FAIR) Qualitative vs. Quantitative Methods What’s the difference? Quantitative – Uses cardinal numbers – everyone understands numbers 3 means 3 and $100k means $100k. You can add, subtract, or do whatever you wish with numbers – you don’t have to guess! But – Quantitative approaches require data, either actual/historical, or estimated. This may or may not be as big a problem as you might think! © 2010 Aliado Accesso LLC
- 15. Factor Analysis of Information Risk (FAIR) Measurement What’s the purpose of taking a measurement? To reduce uncertainty . Sometimes the “perfect” answer is unattainable. But, in many cases, it doesn’t matter. A reduction in uncertainty is what is required. How much do we need to reduce uncertainty? Only as much as required by the decision at hand. And if we cannot reduce uncertainty to that level, then what? We can either collect more measurements, or work with what we have. © 2010 Aliado Accesso LLC
- 16. Factor Analysis of Information Risk (FAIR) Variability and Uncertainty What’s the difference? “Variability is the effect of chance and is a function of the system. It is not reproducible through either study or further measurement, but may be reduced by changing the physical system” 1 “Uncertainty is the assessor’s lack of knowledge (level of ignorance) about the parameters that characterize the physical system being modeled. It is sometimes reducible through further measurement or study, or by consulting more experts” 1 1 David Vose, Risk Analysis, A Quantitative Guide, 3rd edition, 2008, pp. 47-48 © 2010 Aliado Accesso LLC
- 17. So, now that we have addressed all of that – What is FAIR? © 2010 Aliado Accesso LLC
- 18. Factor Analysis of Information Risk (FAIR) Defensible Risk Analysis Framework of interconnected models that describe how key elements of the information risk landscape work. Models that analyze the underlying dynamics of the information risk landscape. Developed in 2001 and under continual evolution, FAIR was created by a CISO who was trying to find answers to : • How much risk do we have? • How much less/more risk will we have if ...? • What are our most significant issues? © 2010 Aliado Accesso LLC
