What is a System Audit?

It is an independent and objective evaluation activity to assess whether information systems contribute to management objectives and are properly controlled. It is conducted based on the "System Audit Standards" established by the Ministry of Economy, Trade and Industry (METI). The most important point is that the auditor must be in a position independent from the organization being audited.

Flow of a System Audit (4 Steps)

  1. Audit Planning: Determine the audit scope, objectives, and schedule
  2. Preliminary Survey: Gain an overview of the target system
  3. Main Investigation: Collect audit evidence (interviews, document reviews, testing)
  4. Reporting and Follow-up: Create the audit report, propose improvements, and verify the status of improvements

What are Internal Controls?

This refers to the internal mechanisms within a company for properly managing business operations. Representative frameworks include the COSO standard in the U.S. and the standard set by Japan's Financial Services Agency.

The 4 Objectives of Internal Controls

Internal controls consist of the following four objectives. Effectiveness and efficiency of operations means achieving management goals. Reliability of financial reporting ensures the accuracy of financial statements. Compliance refers to adhering to laws and regulations, and safeguarding assets aims to prevent unauthorized acquisition or loss.

The 6 Basic Components of Internal Controls

  1. Control Environment (organizational culture)
  2. Risk Assessment and Response
  3. Control Activities (segregation of duties, authorization procedures)
  4. Information and Communication
  5. Monitoring (ongoing oversight)
  6. Response to IT

What is the J-SOX Law?

Its official name is the Internal Control Reporting System based on the Financial Instruments and Exchange Act. It has applied to listed companies since fiscal year 2008, with the purpose of ensuring the reliability of financial reporting. Management must submit an "Internal Control Report" and undergo an audit by a certified public accountant. This system is the Japanese version of the U.S. Sarbanes-Oxley Act (SOX Act).

Key Points for the IT Passport Exam

The independence and objectivity of the system auditor are frequently tested. Identifying the terminology of the 4 objectives and 6 components of internal controls is also commonly asked. Understanding the relationship between the J-SOX law and financial reporting will help you score points.

Typical Patterns in Past Exam Questions

Study Tips

The one-line keyword for system audits is "evaluation from an independent position." Memorize the 4 objectives of internal controls with the mnemonic "Operations, Finance, Compliance, Assets." Clearly understand that J-SOX is based on the Financial Instruments and Exchange Act and is the Japanese version of the U.S. SOX Act; this will prevent confusion on the exam.

Summary
