IT Audit Considerations for CPA Candidates
As a Certified Public Accountant (CPA), understanding Information Technology (IT) audit is crucial. Modern businesses rely heavily on IT systems for operations, data management, and financial reporting. This module will explore key IT audit considerations that are essential for CPA exam preparation.
Why IT Audits Matter in a CPA Context
IT audits are not just for IT professionals. CPAs need to assess the reliability and security of IT systems that impact financial statements. This includes evaluating internal controls over IT processes to ensure data integrity, confidentiality, and availability. A robust IT audit framework helps mitigate risks such as data breaches, system failures, and fraudulent activities.
Key Areas of IT Audit Focus
Several key areas are consistently examined during IT audits. These areas form the backbone of IT control assessment and are frequently tested in CPA exams.
| Audit Area | Description | CPA Relevance |
|---|---|---|
| General IT Controls (GITC) | Controls that apply to all or most IT systems and applications, such as access security, change management, and operations. | Foundation for application controls; ensures a stable and secure IT environment. |
| Application Controls | Controls embedded within specific software applications to ensure data accuracy, completeness, and validity of transactions. | Directly impact the integrity of financial data processed by applications. |
| Information Security | Measures to protect information assets from unauthorized access, use, disclosure, disruption, modification, or destruction. | Crucial for data confidentiality, integrity, and availability, impacting financial reporting and compliance. |
| Business Continuity & Disaster Recovery | Plans and procedures to ensure critical business functions can continue during and after a disruptive event. | Ensures the availability of financial data and systems, preventing significant financial losses. |
| System Development Life Cycle (SDLC) | Controls over the planning, design, development, implementation, and maintenance of IT systems. | Ensures new systems are secure and reliable from inception, preventing future control weaknesses. |
General IT Controls (GITC)
GITC are foundational. They create an environment where application controls can operate effectively. Key GITC include:
- Access Security: Controls over who can access IT resources and what they can do (e.g., user authentication, authorization, segregation of duties).
- Change Management: Processes for managing changes to IT systems and applications to prevent unintended consequences.
- Operations: Controls over the daily operation of IT systems, including job scheduling, data backup, and system monitoring.
- System Development and Maintenance: Controls over the development and maintenance of IT systems to ensure they are secure and functional.
To establish a secure and stable IT environment that supports the effective operation of application controls.
Application Controls
Application controls are specific to individual software applications and are designed to ensure the accuracy, completeness, and validity of transactions. They can be categorized as:
- Input Controls: Ensure data entered into the system is accurate and complete (e.g., data validation, edit checks).
- Processing Controls: Ensure data is processed correctly (e.g., arithmetic accuracy checks, sequence checks).
- Output Controls: Ensure the output generated by the system is accurate and complete (e.g., reconciliation of output to source data, review of reports).
Imagine a bakery. Input controls are like the baker checking the ingredients list before baking to ensure they have the right amounts and types of flour, sugar, etc. Processing controls are like the oven's thermostat ensuring the correct baking temperature and time. Output controls are like tasting the cake to ensure it's baked properly and tastes good before serving it to customers. In IT, this translates to validating data entered, ensuring calculations are correct, and reviewing reports for accuracy.

Information Security and Risk Management
Protecting sensitive financial data is paramount. CPAs must assess an organization's information security policies and procedures. This includes evaluating controls related to:
- Confidentiality: Preventing unauthorized disclosure of sensitive information.
- Integrity: Ensuring data is accurate and complete, and has not been tampered with.
- Availability: Ensuring that IT systems and data are accessible when needed.
A data breach can have severe financial and reputational consequences. CPAs play a role in assessing the controls designed to prevent such breaches.
Business Continuity and Disaster Recovery (BC/DR)
CPAs need to understand how an organization plans to maintain operations and recover IT systems in the event of a disaster. This involves reviewing BC/DR plans, testing procedures, and assessing the adequacy of backup and recovery mechanisms. The goal is to ensure that critical financial data and systems can be restored promptly.
IT Audit in the CPA Exam
CPA exams often include questions related to IT audit concepts, internal controls over IT, and risk assessment. Understanding these areas will help you identify control weaknesses, assess risks, and propose appropriate audit procedures. Focus on the 'why' behind each control and its impact on financial reporting.
