Which of the following decision tree nodes have probability attached to their branches?

  1. Root node
  2. Event node
  3. End node
  4. Decision node

Answer(s): B

Explanation:

Event nodes represents the possible uncertain outcomes of a risky decision, with at least two nodes to illustrate the positive and negative range of events. Probabilities are always attached to the branches of event nodes.

Incorrect Answers:
A: Root node is the starting node in the decision tree, and it has no branches.

C: End node represents the outcomes of risk and decisions and probability is not attached to it.

D: It represents the choice available to the decision maker, usually between a risky choice and its non-risky counterpart. As it represents only the choices available to the decision makers, hence probability is not attached to it.



Which of the following IS processes provide indirect information? Each correct answer represents a complete solution. Choose three.

  1. Post-implementation reviews of program changes
  2. Security log monitoring
  3. Problem management
  4. Recovery testing

Answer(s): A,B,C

Explanation:

Security log monitoring, Post-implementation reviews of program changes, and Problem management provide indirect information. Security log monitoring provide indirect information about certain controls in the security environment, particularly when used to analyze the source of failed access attempts.

Post-implementation reviews of program changes provide indirect information about the effectiveness of internal controls over the development process.

Problem management provide indirect information about the effectiveness of several different IS processes that may ultimately be determined to be the source of incidents.

Incorrect Answers:
D: Recovery testing is the direct evidence that the redundancy or backup controls work effectively. It doesn't provide any indirect information.



You are the risk professional of your enterprise. You need to calculate potential revenue loss if a certain risks occurs. Your enterprise has an electronic (e-commerce) web site that is producing US $1 million of revenue each day, then if a denial of service (DoS) attack occurs that lasts half a day creates how much loss?

  1. US $250,000 loss
  2. US $500,000 loss
  3. US $1 million loss
  4. US $100,000 loss

Answer(s): B

Explanation:

Denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) is an attempt to make a computer resource unavailable to its intended users. Although the means to carry out, motives for, and targets of a DoS attack may vary, it generally consists of the concerted efforts of person or persons to prevent an Internet site or service from functioning efficiently or at all, temporarily or indefinitely. Perpetrators of DoS attacks typically target sites or services hosted on high-profile web servers such as banks, credit card payment gateways, and even root name-servers. The term is generally used with regards to computer networks, but is not limited to this field; for example, it is also used in reference to CPU resource management. As the total revenue of the website for the day is $1 million, and due to denial of service attack it is unavailable for half day.

Therefore,
Revenue loss = $1,000,000/2
= $500,000

Incorrect Answers:
A, C, D: These are wrong answers.



Which of the following process ensures that extracted data are ready for analysis?

  1. Data analysis
  2. Data validation
  3. Data gathering
  4. Data access

Answer(s): B

Explanation:

Data validation ensures that extracted data are ready for analysis. One objective is to perform data quality tests to ensure data are valid complete and free of errors. This may also involve making data from different sources suitable for comparative analysis.

Incorrect Answers:
A: Analysis of data involves simple set of steps or complex combination of commands and other functionality. Data analysis is designed in such a way to achieve the stated objectives from the project plan. Although this may be applicable to any monitoring activity, it would be beneficial to consider transferability and scalability.
This may include robust documentation, use of software development standards and naming conventions.

C: Data gathering is the process of collecting data on risk to be monitored, prepare a detailed plan and define the project's scope. In the case of a monitoring project, this step should involve process owners, data owners, system custodians and other process stakeholders.

D: In the data access process, management identifies which data are available and how they can be acquired in a format that can be used for analysis. There are two options for data extraction:
Extracting data directly from the source systems after system owner approval Receiving data extracts from the system custodian (IT) after system owner approval
