Top 3 Considerations when evaluating IT Application Controls

Do you know the top three key considerations when evaluating IT application controls?

This newsletter dives into the world of application controls, essential safeguards for protecting your organization's data.  As IT auditors, we understand the critical role these controls play in securing information flowing between systems and governing vital business processes.

IT Application controls can encompass various areas, from financial transactions to core IT functions. Imagine a scenario where an employee's termination date is entered into the system.

Strong application controls would ensure this information automatically updates across multiple applications, seamlessly revoking the user's access.

This is just one example, and throughout my career, I've encountered many such instances during application control audits.

Now, let's equip you with the top three key considerations when evaluating application controls, whether you're an auditor or someone working with an auditor:

1. Configurations

Have you ever wondered how applications know what to do?  The secret lies in their configurations, often referred to as "config files." These files define the settings, options, and preferences that dictate an application's behavior.  For IT auditors, configurations are like a roadmap – understanding them is crucial for evaluating the effectiveness of controls.

Why are Configurations Important in Audits?

Think of a control as a safeguard against a risk. 

For example, let's say a control is designed to automatically disable a user account upon termination.  This control aims to minimize the risk of unauthorized access.  But here's the twist: the effectiveness of this control hinges entirely on the configuration. 

If the configuration is set to transfer the termination date only once, after the actual termination event, the control fails to achieve its purpose.

The Power of Proper Configuration

Ideally, configurations should be enabled in a way that effectively addresses the risk they're designed to mitigate. 

If a configuration isn't functioning properly, it's a red flag for auditors.  A thorough evaluation of configurations ensures controls are working as intended, providing a clear "green light" for audit success.

What's Next?

This newsletter serves as a foundational understanding of configurations.  In future discussions, we'll delve into the specifics of evaluating configurations, exploring the different aspects you need to consider to ensure a comprehensive and effective IT audit.

2. Access

Secure configurations are only effective if the right people have access to them.

As an auditor, you'll undoubtedly review these configurations during walkthroughs. However, relying solely on this snapshot wouldn't paint the whole picture.

The real concern lies in unauthorized changes.

What if someone with malicious intent alters these configurations, fundamentally affecting the application's behavior? This is where access controls become crucial. 

Your primary task is to identify all the roles and users with access to application configurations. This information should be documented in your audit working papers. Remember, you're not here to judge the appropriateness of access granted by the organization. Your focus is on creating a comprehensive list. 

You need to identify all users and roles with configuration access rights.

This allows you to assess the potential impact of unauthorized modifications. 

By understanding who can access and modify application configurations, you gain valuable insight into the overall control environment. This knowledge empowers you to assess potential risks and ensure the continued effectiveness of application controls.

3. Completeness and Accuracy

In the world of IT auditing, application controls play a critical role in safeguarding the integrity of data during transfers between systems.  This newsletter dives into two key aspects I focus on when evaluating these controls: completeness and accuracy.

Data Completeness

 Imagine you're overseeing the transfer of a crucial document or a batch of records from one system to another. Completeness ensures  every single piece of data makes the journey successfully.  Think of it like verifying all 50 guests on your invitation list arrive at the party – no missing attendees! In our auditing context, we would  confirm that all 50 records intended for transfer are present in the destination system.

Data Accuracy

Data accuracy is equally important. 

This ensures the information  arrives unchanged and unaltered.  Continuing our party analogy,  imagine a guest accidentally receives the wrong invitation, showing up on the wrong date.

In the data world, this translates to a value like $2,500 in one system being transferred as $2,50.0 in the other. 

This discrepancy could have significant consequences.  Therefore, verifying that data remains  untampered with during transfer is crucial for maintaining trust in the information being exchanged.

By focusing on both completeness and accuracy, we can ensure application controls effectively safeguard the integrity of data transfers within your systems.

These are the top three things to keep in mind when evaluating an IT application control. There are many other aspects I'll discuss in future newsletters, but these are the top three that come to mind whenever someone asks me about the most valuable aspects of an application control.
