Question

Your author discusses four different access models, but there is a fifth that is gaining interest, particularly in a cloud environment.

Read through the TBAC: "Enforcing Security Properties in Task-based Systems" (or find additional resources), then complete the following for each of the five models:

• Provide a brief description of the model.

• Provide a scenario where the model would be the optimal choice for access control, and why.

• Provide a scenario where the model is the least optimal choice for access control, and why.

Answer 1

In order to complete the task, you have to assume that your author illustrates four different access models; however there is a fifth which is gaining the interest, specifically in a cloud atmosphere. Read via the TBAC: ‘Enforcing Security Properties in Task-based Systems’ (or explore extra resources), then complete the given for each of the 5 models: 1) Give a concise explanation of the model. 2) Write a scenario in which the model would be the optimal choice for access control and explain why. 3) Give a scenario in which the model is the least optimal choice for access control and illustrate why.
