A. Attribute sampling

B. Variable sampling

C. Stratified mean per unit

D. Difference estimation

Correct Answer: A


Explanation: Attribute sampling is the primary sampling method used for compliance testing. Attribute sampling is a sampling model that is used to estimate the rate of occurrence of a specific quality (attribute) in a population and is used in compliance testingto confirm whether the quality exists. The other choices are used in substantive testing, which involves testing of details or quantity.

Question 4:

Which of the following is normally a responsibility of the chief security officer (CSO)?

A. Periodically reviewing and evaluating the security policy

B. Executing user application and software testing and evaluation

C. Granting and revoking user access to IT resources

D. Approving access to data and applications

Correct Answer: A



The role of a chief security officer (CSO) is to ensure that the corporate security policy

and controls are adequate to prevent unauthorized access to the company assets,

including data, programs and equipment. User application and other software testing and evaluation

normally are the responsibility of the staff assigned to development and

maintenance. Granting and revoking access to IT resources is usually a function of

network or database administrators. Approval of access to data and applications is the

duty of the data owner.

Question 5:

A benefit of open system architecture is that it:

A. facilitates interoperability.

B. facilitates the integration of proprietary components.

C. will be a basis for volume discounts from equipment vendors.

D. allows for the achievement of more economies of scale for equipment.

Correct Answer: A


Explanation: Open systems are those for which suppliers provide components whose interfaces are defined by public standards, thus facilitating interoperability between systems made by different vendors. In contrast, closed system components are built to proprietary standards so that other suppliers\’ systems cannot or will not interface with existing systems.

Question 6:

An IS auditor is reviewing an IT security risk management program. Measures of security risk should:

A. address all of the network risks.

B. be tracked over time against the IT strategic plan.

C. take into account the entire IT environment.

D. result in the identification of vulnerability tolerances.

Correct Answer: C



When assessing IT security risk, it is important to take into account the entire IT environment. Measures of security risk should focus on those areas with the highest criticality so as to achieve maximum risk reduction at the lowest possible cost. IT strategic plans are not granular enough to provide appropriate measures. Objective metrics must be tracked over time against measurable goals, thus the management of risk is enhanced by comparing today\’s results against last week, last month, last quarter. Risk measures will profile assets on a network to objectively measure vulnerability risk. They do not identify tolerances.

Question 7:

Information for detecting unauthorized input from a terminal would be BEST provided by the:

A. console log printout.

B. transaction journal.

C. automated suspense file listing.

D. user error report.

Correct Answer: B


Explanation: The transaction journal would record all transaction activity, which then could be compared to the authorized source documents to identify any unauthorized input. A console log printout is not the best, because it would not record activity from a specific terminal. An automated suspense file listing would only list transaction activity where an edit error occurred, while the user error report would only list input that resulted in an edit error.

Question 8:

In a client-server system, which of the following control techniques is used to inspect activity from known or unknown users?

A. Diskless workstations

B. Data encryption techniques

C. Network monitoring devices

D. Authentication systems

Correct Answer: C


Network monitoring devices may be used to inspect activities from known or unknown users and can identify client addresses, which may assist in finding evidence of unauthorized access. This serves as a detective control. Diskless workstations preventaccess control software from being bypassed. Data encryption techniques can help protect sensitive or propriety data from unauthorized access, thereby serving as a preventive control. Authentication systems may provide environmentwide, logical facilities that can differentiate among users, before providing access to systems.

Question 9:

An IS auditor should expect the responsibility for authorizing access rights to production data and systems to be entrusted to the:

A. process owners.

B. system administrators.

C. security administrator.

D. data owners.

Correct Answer: D


Data owners are primarily responsible for safeguarding the data and authorizing access to production data on a need-to-know basis.

Question 10:

Which of the following is the BEST way to handle obsolete magnetic tapes before disposing of them?

A. Overwriting the tapes

B. initializing the tape labels

C. Degaussing the tapes

D. Erasing the tapes

Correct Answer: C


The best way to handle obsolete magnetic tapes is to degauss them. This action leaves a very low residue of magnetic induction, essentially erasing the data from the tapes. Overwriting or erasing the tapes may cause magnetic errors but would not remove the data completely. Initializing the tape labels would not remove the data that follows the label.
