NIST SP 800-53 identifies controls in three primary classes. What are they?

  1. Technical, Administrative, and Environmental
  2. Preventative, Detective, and Corrective
  3. Technical, Operational, and Management
  4. Administrative, Technical, and Operational

Answer(s): C

Explanation:

NIST SP 800-53 is used to review security in any organization, that is, in reviewing physical security. The Physical and Environmental Protection family includes 19 different controls. Organizations use these controls for better physical security. These controls are reviewed to determine if they are relevant to a particular organization or not. Many of the controls described include additional references that provide more details on how to implement them. The National Institute of Standards and Technology (NIST) SP 800-53 rev 3 identifies 18 families of controls. It groups these controls into three classes:
Technical Operational Management



While defining the risk management strategies, what are the major parts to be determined first? Each correct answer represents a part of the solution. Choose two.

  1. IT architecture complexity
  2. Organizational objectives
  3. Risk tolerance
  4. Risk assessment criteria

Answer(s): B,C

Explanation:

While defining the risk management strategies, risk professional should first identify and analyze the objectives of the organization and the risk tolerance. Once the objectives of enterprise are known, risk professional can detect the possible risks which can occur in accomplishing those objectives. Analyzing the risk tolerance would help in identifying the priorities of risk which is the latter steps in risk management. Hence these two do the basic framework in risk management.

Incorrect Answers:
A: IT architecture complexity is related to the risk assessment and not the risk management, as it does much help in evaluating each significant risk identified.

D: Risk assessment is one of the various phases that occur while managing risks, which uses quantitative and qualitative approach to evaluate risks. Hence risk assessment criteria is only a part of this framework.



Which of the following are true for quantitative analysis?
Each correct answer represents a complete solution. Choose three.

  1. Determines risk factors in terms of high/medium/low.
  2. Produces statistically reliable results
  3. Allows discovery of which phenomena are likely to be genuine and which are merely chance occurrences
  4. Allows data to be classified and counted

Answer(s): B,C,D

Explanation:

As quantitative analysis is data driven, it: Allows data classification and counting.
Allows statistical models to be constructed, which help in explaining what is being observed. Generalizes findings for a larger population and direct comparisons between two different sets of data or observations.
Produces statistically reliable results.
Allows discovery of phenomena which are likely to be genuine and merely occurs by chance.

Incorrect Answers:
A: Risk factors are expressed in terms of high/medium/low in qualitative analysis, and not in quantitative analysis.



Ned is the project manager of the HNN project for your company. Ned has asked you to help him complete some probability distributions for his project. What portion of the project will you most likely use for probability distributions?

  1. Bias towards risk in new resources
  2. Risk probability and impact matrixes
  3. Uncertainty in values such as duration of schedule activities
  4. Risk identification

Answer(s): C

Explanation:

Risk probability distributions are likely to be utilized in uncertain values, such as time and cost estimates for a project.

Incorrect Answers:
A: Risk probability distributions do not typically interact with the bias towards risks in new resources. B: Risk probability distributions are not likely to be used with risk probability and impact matrices.
D: Risk probability distributions are not likely the risk identification.
