ISACA Information System Auditing Process — Questions and Answers

Question 1: What is the primary objective of an information system audit?

To develop software
Evaluate effectiveness of controls (Correct answer)
Design hardware systems
Manage IT projects

Correct answer: Evaluate effectiveness of controls

The primary objective of an information system audit is to evaluate the effectiveness of an organization's IT controls. This assessment determines whether controls are adequately protecting information assets, ensuring data integrity, confidentiality, and availability, and helping to identify weaknesses and ensure compliance.

Question 2: Which phase of the audit process involves identifying key risks and controls?

Reporting
Planning (Correct answer)
Fieldwork
Follow-up

Correct answer: Planning

The planning phase is crucial in an IS audit as it involves defining the audit scope, objectives, and methodology. During this phase, auditors identify key risks and controls relevant to the systems being audited, which guides the subsequent fieldwork and ensures an efficient and focused audit approach.

Question 3: What is the purpose of fieldwork in IS audit?

Prepare audit report
Gather and analyze evidence (Correct answer)
Define audit scope
Conduct training

Correct answer: Gather and analyze evidence

Fieldwork is the phase where auditors execute the planned audit procedures to collect and analyze evidence. This involves examining documentation, interviewing personnel, and testing controls to determine their effectiveness and identify any control deficiencies or non-compliance within the information systems.

Question 4: Why is communication important during the audit process?

To delay audit
Keep stakeholders informed (Correct answer)
Avoid findings
Ignore feedback

Correct answer: Keep stakeholders informed

Effective communication throughout the audit process is vital to keep all relevant stakeholders, including management and auditees, informed about the audit's progress, findings, and potential implications. This fosters transparency, facilitates cooperation, and ensures that recommendations are well-received and acted upon.

Question 5: What is an audit program?

Financial statement
Plan of audit procedures (Correct answer)
Project management plan
Security policy

Correct answer: Plan of audit procedures

An audit program is a detailed, step-by-step plan that outlines the specific procedures and tests to be performed during an audit engagement. It ensures a systematic and comprehensive approach to gathering evidence, helping auditors achieve their objectives efficiently and consistently while maintaining quality.

Question 6: During an audit, what is the importance of sampling?

Test all transactions
Test a representative subset (Correct answer)
Ignore data
Make assumptions

Correct answer: Test a representative subset

Sampling is important in an IS audit because it allows auditors to draw conclusions about an entire population of data or transactions by examining only a representative subset. This approach is efficient and cost-effective, especially when dealing with large volumes of data, while still providing sufficient assurance about control effectiveness.

Question 7: What should an audit report include?

Only positive feedback
Findings, conclusions, recommendations (Correct answer)
Financial statements
Employee evaluations

Correct answer: Findings, conclusions, recommendations

A comprehensive audit report should clearly present the audit findings, which are factual observations of control weaknesses or strengths. It must also include conclusions drawn from these findings and actionable recommendations for improvement, enabling management to address identified issues effectively and enhance the control environment.

Question 8: What is the follow-up phase in the audit process?

Initial planning
Checking implementation of actions (Correct answer)
Gathering evidence
Drafting reports

Correct answer: Checking implementation of actions

The follow-up phase is critical to ensure that management has effectively implemented the corrective actions recommended in the audit report. This phase verifies that identified control weaknesses have been addressed, thereby improving the organization's control environment and reducing risks to information systems.

Question 9: Which standard guides IS audit practices?

ISO 9001
ISACA GAAS (Correct answer)
HIPAA
SOX

Correct answer: ISACA GAAS

ISACA's Generally Accepted Auditing Standards (GAAS) provide a framework of principles and practices that guide information systems auditors in conducting their work. Adhering to these standards ensures consistency, quality, and credibility in IS audit engagements, promoting professional excellence.
