ACC676: Audit of Accounting Information Systems

A complete guide to SNHU's ACC-676 Audit of Accounting Information Systems, extending the IT-focused auditing competency from ACC-675 into a dedicated exploration of auditing accounting information systems specifically.

GraduateSNHUIT Systems AuditingAPA 7th Edition

ACC-676 builds on ACC-675's foundation in IT control and SOX compliance, focusing specifically on the methodology and standards for auditing accounting information systems as complete, integrated technical environments.

Auditing the system as a whole

Where ACC-675 introduces IT control testing and SOX 404 compliance, ACC-676 extends into auditing the accounting information system holistically — evaluating how its components work together to produce reliable financial information.

Standards-based systems audit methodology

The course covers applying professional auditing standards specifically to information systems, examining data integrity, access controls, and system reliability as an integrated audit objective.

Worked example: auditing the system, not just its controls in isolation

  • Isolated control test: Confirming a single access restriction is enforced
  • Holistic systems audit: Evaluating how that access control interacts with data integrity checks and reporting reliability across the whole system
  • Lesson: ACC-676 teaches evaluating an accounting information system as an integrated whole, not a checklist of disconnected individual controls

Frequently asked questions

How does ACC-676 extend beyond the IT control testing covered in ACC-675?

ACC-675 focuses on the SOX 404 compliance foundation — testing individual process controls and interpreting ISACA/PCAOB standards — while ACC-676 extends into evaluating the accounting information system holistically, examining how individual controls, data integrity checks, and access restrictions function together to produce reliable financial information as an integrated system, not just as isolated compliance checkpoints.

Why does auditing an accounting information system holistically matter more than testing individual controls one at a time?

Individual controls can each function correctly in isolation while still failing to produce reliable financial information overall if they don't interact soundly — a properly enforced access restriction combined with a data integrity gap elsewhere in the system can still allow unreliable information to reach financial reports. ACC-676 teaches holistic systems auditing because a genuinely reliable audit opinion on an information system requires understanding how all its components work together, not just confirming each one independently passes its own isolated test.
