Off the Shelf Software Audit of Controls
When a client uses off-the-shelf software for their accounting and financial processes, auditors need to consider specific aspects of these systems as part of their internal control evaluation and testing. Internal controls in such environments are crucial for ensuring the integrity, confidentiality, and availability of financial data. The procedures to test these controls often focus on assessing both the operational effectiveness of the controls and the client's use of the software. Here is a description of the internal controls and testing procedures:
Internal Controls for Off-the-Shelf Software
Access Controls
User Access Management: Controls to ensure that access to the software is restricted based on roles and responsibilities.
Authentication Mechanisms: Use of strong passwords, multi-factor authentication, and other methods to verify the identity of users.
Data Integrity Controls
Input Controls: Ensure accuracy and completeness of data entry.
Processing Controls: Checks and validations within the software to ensure that transactions are processed correctly.
Output Controls: Ensure that reports and exports from the system are accurate and complete.
Change Management Controls
Procedures for managing updates and modifications to the software, including testing and approval of changes.
Backup and Recovery Controls:
Regular backups of financial data and systems, along with tested procedures for data recovery in case of a loss.
System and Data Security Controls:
Measures to protect the software and data from unauthorised access, including antivirus software, firewalls, and encryption.
Audit Trail and Transaction Logging:
Features within the software that log user activities and transactions, enabling traceability and review.
Procedures to Test Internal Controls
Access Controls Testing:
Review user access lists and permissions to ensure they are appropriate for each user's role and responsibilities.
Test authentication mechanisms for robustness.
Data Integrity Testing
Perform data entry and processing tests to verify that the system accurately captures and processes transactions.
Verify that output reports and exports match expected results and source data.
Change Management Testing
Review documentation and logs related to software changes, updates, and patches to ensure they have been properly authorized, tested, and implemented.
Backup and Recovery Testing
Examine backup schedules and policies to ensure they are adequate.
Test the recovery process to verify that data can be successfully restored from backup files.
Security Controls Testing
Assess the effectiveness of security measures such as antivirus, firewalls, and encryption in protecting against unauthorized access and data breaches.
Perform vulnerability scans or penetration tests to identify potential weaknesses.
Audit Trail and Transaction Log Testing:
Review audit trails and logs to ensure that they accurately record user activities and transactions.
Test the completeness and integrity of the logs by tracing selected transactions through the system.
In performing these tests, auditors use a combination of techniques including inquiry, observation, inspection of relevant documentation, and re-performance of controls. They may also use computer-assisted audit techniques (CAATs) to test controls in an automated manner, especially when dealing with large volumes of transactions. The objective is to assess whether the internal controls are designed effectively and operating as intended, reducing the risk of material misstatement in the financial statements.
