In a given organization there were three information assets (X, Y, and Z) with the following characteristics: Information asset X likelihood of an attack: 40% Information asset X attack success probability: 50% Information asset X value: $ 200K Information asset X probable loss: 20% Uncertainty related to information asset X: 10 % Information asset Y likelihood of an attack: 20% Information asset Y attack success probability: 75% Information asset Y value: $ 300K Information asset Y probable loss: 15% Uncertainty related to information asset Y: 10 % Information asset Z likelihood of an attack: 50% Information asset Z attack success probability: 60% Information asset Z value: $ 400K Information asset Z probable loss: 5% Uncertainty related to information asset Z: 10 % Given those parameters what can be said about risk assessment of those three information assets? What information asset has the greater risk altogether? Answer 1Choose...All information assets have equal valuesInformation assets X and Y have equal values, superior to ZInformation assets X and Z have equal values, superior to YInformation asset YInformation asset XInformation asset ZInformation assets Y and Z have equal values, superior to X What information asset has the greater loss frequency? Answer 2Choose...All information assets have equal valuesInformation assets X and Y have equal values, superior to ZInformation assets X and Z have equal values, superior to YInformation asset YInformation asset XInformation asset ZInformation assets Y and Z have equal values, superior to X What information asset has the greater loss magnitude? Answer 3Choose...All information assets have equal valuesInformation assets X and Y have equal values, superior to ZInformation assets X and Z have equal values, superior to YInformation asset YInformation asset XInformation asset ZInformation assets Y and Z have equal values, superior to X
What information asset has the greater risk altogether? → Information asset X, What information asset has the greater loss frequency? → Information asset Z, What information asset has the greater loss magnitude? → Information asset Y
Software piracy is a violation of intellectual property when you perform how many of three of the following actions: (i) duplication, (ii) installation, and (iii) distribution of copyrighted computer software? Select one: When you perform any one of those three actions. Only when you perform all of those three actions. None of these three actions relates to violation of intellectual property. When you perform at least two of those three actions. None of those three actions implies in violation, the violation only occurs when you acquire economic gains from these actions.
When you perform any one of those three actions.
In a given organization there were three information assets (X, Y, and Z) with the following characteristics: Information asset X likelihood of an attack: 25% Information asset X attack success probability: 40% Information asset X value: $ 60K Information asset X probable loss: 10% Uncertainty related to information asset X: 10 % Information asset Y likelihood of an attack: 60% Information asset Y attack success probability: 30% Information asset Y value: $ 100K Information asset Y probable loss: 5% Uncertainty related to information asset Y: 10 % Information asset Z likelihood of an attack: 15% Information asset Z attack success probability: 70% Information asset Z value: $ 80K Information asset Z probable loss: 8% Uncertainty related to information asset Z: 10 % Given those parameters what can be said about risk assessment of those three information assets? What information asset has the greater loss magnitude? Answer 1Choose...All information assets have equal valuesInformation asset ZInformation asset YInformation asset XInformation assets Y and Z have equal values, superior to XInformation assets X and Z have equal values, superior to YInformation assets X and Y have equal values, superior to Z What information asset has the greater loss frequency? Answer 2Choose...All information assets have equal valuesInformation asset ZInformation asset YInformation asset XInformation assets Y and Z have equal values, superior to XInformation assets X and Z have equal values, superior to YInformation assets X and Y have equal values, superior to Z What information asset has the greater risk altogether?
Your answer is incorrect. Applying the risk formula at page 258 of our textbook (5th edition) we obtain the following values: Loss Frequency of information asset X: 10% Loss Frequency of Information asset Y: 12% Loss Frequency of Information asset Z: 10.5% Loss Magnitude of Information asset X: $ 6K Loss Magnitude of Information asset Y: $ 5K Loss Magnitude of Information asset Z: $ 6.4K Risk for Information asset X: $ 0.7 K Risk for Information asset Y: $ 0.7 K Risk for Information asset Z: $ 0.77 K The correct answer is: What information asset has the greater loss magnitude? → Information asset X, What information asset has the greater loss frequency? → Information asset Y, What information asset has the greater risk altogether? → Information asset Z
