An Accountant’s Guide to IT General Controls (ITGCs)

ITGCs Overview

• Just like accounting processes are controlled under frameworks like COSO, the systems that support those processes are governed by IT General Controls (ITGCs).
• ITGC responsibilities are shared:
  
  • Your internal IT team is responsible for ITGCs over your internal systems
  • Your vendors provide SOC 1 reports to demonstrate ITGCs over their systems
• Bridging the gap matters: Strong collaboration between Accounting and IT simplifies audits and compliance.
• Data is a financial asset: Cyber risk can create financial reporting risk. 
• ITGCs are layered: Security frameworks (like SOC 2 or NIST) are only one part of a broader control environment.
• Understanding the basics helps: Accountants don’t need technical depth, but they do need conceptual clarity. 

What Are IT General Controls (ITGCs)?

In a modern SOX environment, internal controls fall into two broad categories:

• Accounting controls, which accountants know well
• IT General Controls (ITGCs), which often feel like a black box
  

ITGCs are the foundational controls that ensure IT systems operate reliably, securely, and consistently. Because modern financial reporting depends heavily on technology, weaknesses in ITGCs can directly impact the accuracy and completeness of financial statements.

At a high level, ITGCs exist to reduce the risk that:

• Unauthorized users access financial systems
• Data is changed without approval
• System failures go undetected
• Reports used for financial reporting are incomplete or inaccurate
  

Why Do ITGCs Matter to Accountants?

Accountants are accountable for the integrity of financial reporting, even when it depends on systems managed by IT.

If an IT control fails, it can lead to:

• Incorrect financial reports
• Manual testing by auditors
• Expanded audit scope
• Increased compliance costs

Understanding ITGCs helps accounting teams explain risks clearly, evaluate audit findings, and work more effectively with IT and GRC teams.

The Core Categories of IT General Controls

While implementations vary by company size and industry, ITGCs typically fall into a few common categories. 

1. Logical Access Controls

Purpose: Ensure only authorized users can access sensitive systems and data.

What this looks like in practice:

• User account creation and removal
• Role-based access
• Segregation of duties
• Least privilege access
• Multi-factor authentication

Why accountants care: Prevents unauthorized changes to financial data.

2. Change Management Controls

Purpose: Ensure system changes are approved, tested, and documented.

What this looks like in practice:

• Approval workflows for system changes
• Testing, including user acceptance testing where applicable
• Documentation of updates and fixes

Why accountants care: Prevents errors caused by untested system changes.

3. System Operations Controls

Purpose: Ensure systems operate reliably day to day.

What this looks like in practice:

• Monitoring system performance
• Incident and issue management
• Job scheduling and error handling

Why accountants care: Supports operational continuity and reliable reporting.

4. Backup and Recovery Controls

Purpose: Protect critical data and ensure recovery after system failures.

What this looks like in practice:

• Regular data backups
• Disaster recovery testing
• Business continuity plans

Why accountants care: Ensures financial data is not lost and remains available when needed.

The Frameworks Accountants Keep Hearing About (TLDR Edition)

ITGCs don’t exist in isolation. They are supported by broader frameworks that help organizations design, test, and prove controls.

SOC 2

What it is:

An independent assurance report focused on security, availability, and data protection.

When it matters:

Typically optional and driven by company size, customer expectations, or vendor risk programs.

What accountants need to know:

SOC 2 provides comfort that systems are secure and available, but it does not focus on financial reporting accuracy.

SOC 1

What it is:

An assurance report over controls that impact financial reporting.

When it matters:

Required when software or services impact financial reporting.

What accountants need to know:

SOC 1 reduces the need for manual testing by providing report completeness and accuracy.

COSO

What it is:

The foundational framework for internal control over financial reporting.

Key focus:

Five components: Control Environment, Risk Assessment, Control Activities, Information and Communication, and Monitoring.

What accountants need to know:

COSO is the “what.” ITGCs must map back to COSO to be considered effective financial controls.

MAR (Model Audit Rule)

What it is:

A SOX-like framework often used in regulated industries such as insurance.

What accountants need to know:

MAR relies heavily on COSO and incorporates IT controls relevant to financial reporting.

NIST and NIST CSF

What they are:

Technical frameworks for managing cybersecurity risk.

When they matter:

Often required for government or highly regulated environments.

What accountants need to know:

Accountants don’t need to know the technical details, only whether NIST applies and how it maps to financial reporting risk.

How These Frameworks Fit Together

In a mature organization:

• COSO provides the umbrella for internal controls
• ITGCs support COSO objectives
• NIST CSF may guide cybersecurity practices
• SOC reports provide independent assurance

Together, they create a layered approach to risk management, compliance, and operational reliability.

How Automation Helps Simplify ITGC Compliance

Managing ITGCs manually is time-consuming and error-prone. Modern platforms help by:

• Mapping controls to frameworks automatically
• Centralizing evidence collection
• Supporting continuous monitoring
• Improving audit readiness
  

FloQast allows teams to activate frameworks such as COSO, SOC 2, and NIST, removing guesswork and improving collaboration between Accounting and IT.

Making ITGCs Less of a Black Box to Accounting

IT General Controls don’t need to be intimidating. Accountants don’t need to become cybersecurity experts to understand the purpose of ITGCs or explain them to auditors.

By understanding the goals of these controls and how they map to financial reporting risk, accounting teams can reduce audit friction, strengthen compliance, and work more effectively with IT and GRC partners. 

The tools your company uses can make a big difference in how well accountants can support their IT and GRC counterparts. Adopt a solid accounting platform that fully leverages technology to smooth the path between these teams with smart features like AI audit testing and automated evidence collection.
