Businesses rely so much on information systems that auditors need to realize just how essential IT General Controls (ITGC) are. They understand the security, reliability, and integrity of business systems.

IT General Controls (ITGC) provide the baseline, the building blocks of a business’s IT control environment. They help the business system’s data and processes from the risks of unauthorized access, failures and fraud. Strong ITGC help a business meet compliance and effective control objectives according to the frameworks of COBIT, SOX, and ISO 27001.

For those that want to be IT auditors, internal auditors, compliance and/or risk management professionals, understanding ITGC is important. This article discusses the top five IT General Controls that every IT auditor should understand.

What are IT General Controls?

IT General Controls are the procedures and policies that focus on the confidentiality, accuracy, and availability of information control systems. They can be found in any IT environment in a large business and help application controls, business process controls, and organizational process IT systems. They include access controls, system operation controls, and controls for system backups and security.

Poor ITGCs expose the business to operational disruptions, data loss, legal disputes, and false financial statements. Auditors evaluate the ITGC to determine the integrity of business IT.

Why IT General Controls Matter in Auditing

ITGCs have been called the essentials of IT governance and compliance. Where basic controls are lacking, auditors are likely to have little reliance on the automated or application-layer controls. For instance, if an unauthorized person is able to access a production system or make changes to it, the veracity of financial and operational data is in serious jeopardy.

For the ITGCs, auditors consider:

• Risk of unauthorized access is diminished.
• System changes are validated as appropriately authorized.
• Adequate provisions exist for continuity of business operations.
• Protection of confidential and sensitive data is ensured.
• Compliance with applicable laws and regulations is facilitated.
• Reasonableness of financial reporting is enhanced.

There are five critical IT General Controls all auditors should know. The first is Access Management Controls.

1. Access Management Controls

Access Management is widely accepted as the most essential of all ITGC domain areas. These controls are focused on ensuring system, application, and database access is limited to individuals who have been authorized to access them. Access Management Controls are built around the concept of Least Privilege, where users are afforded only those permissions that are required in order for them to perform their job functions.

Key Access Management Controls

• Provisioning and de-provisioning of user accounts
• Role-based access control
• Access control lists
• Password policies
• Multi-factor authentication
• Privileged access control
• Periodic user access reviews

Access Management in ITGC audits is highly focused. This is because inadequate access management controls are frequently a cause of data breaches, system fraud, and IT compliance failures.

2. Change Management Controls

Companies make changes to applications, infrastructure, and databases. This can be infrastructure / application / database changes. Change management controls document necessary steps like proper requests and approvals, testing changes, and implementation.

Change management controls lack the integrity of management if poorly requested and tested changes can be made in production in a disruptive, incomplete, and insecure (for example, a data breach) manner.

Key Change Management Controls

• Formal change requests
• Management approvals
• Testing and quality assurance
• Segregation of duties
• Emergency change procedures
• Deployment documentation

Audit Procedures

Audit may involve:

• Change tickets
• Approval records
• Testing evidence
• Migration logs
• Production deployment records

Routine Audit Findings

• Missing approvals
• Inadequate testing
• Changes without approvals to production environments
• Inadequacy of segregation of duties

Change management controls lack integrity if controls are incomplete, for example if necessary change controls are not documented.

Maintaining systems integrity and operational risks is the purpose for a comprehensive change management program. Change management is a crucial pillar of IT General Controls.

3. IT Operations Controls

IT operations controls are concerned with the management and monitoring of IT systems in the operational phase. Controls assure that systems and processes operate without interruptions.

Availability of IT operations is critical to the objectives of the organization.

Key IT Operations Controls

• Job scheduling and monitoring
• Incident management
• System monitoring
• Capacity management
• Event log reviews
• Performance monitoring

Audit Procedures

Auditors may review:

• Incident tickets
• Monitoring dashboards
• Batch job reports
• System availability reports
• Escalation procedures

Common Audit Findings

• Incomplete incident documentation
• Delayed issue resolution
• Lack of monitoring procedures
• Unreviewed system logs
• Ineffective escalation processes

Four strong IT operations backup and recovery controls offer assurance that business disruption due to unexpected operational issues will be minimized.

4. Backup and Recovery Controls

Backup and recovery controls protect one of the most critical recovery resource and asset that any organization possesses: its data. Recovery controls assist in the restoration of data in the event of hardware failures, cyberattacks, deletions, and disasters.

These controls also help ensure business recovery is possible after a disruption. Organizations with inadequate backup procedures can incur significant loss of business and financial resources.

Key Backup and Recovery Controls

• Automated backup schedules
• Backup monitoring
• Offsite storage
• Disaster recovery planning
• Recovery testing
• Backup retention policies

Audit Procedures

Auditors review:

• Backup logs
• Recovery test results
• Disaster recovery plans
• Backup Schedules
• Data Restoration evidence

Common Audit Findings

• Uninvestigated Failed Backups
• Lack Recovery Testing
• Inadequate Disaster Recovery Plans
• No Backup Monitoring
• Outdated Recovery Procedures

Evidence of recovery testing is more critical to auditors than backup procedures. Organizations need to test their recovery procedures to ensure the data and systems can be restored in a timely manner.

5. Security & Physical Controls

Security controls aim to keep IT assets safe from threats both inside the organization and externally. Both logical security measures and physical safeguards are included to stop access to facilities and infrastructures.

Controls for both physical and logical security are important to the framework of ITGC.

Key Security & Physical Controls

• Data center access restrictions
• Surveillance systems
• Visitor management
• Firewall management
• Endpoint protection
• Network security monitoring

Audit Procedures

Auditors review:

• Physical access logs
• Security policies
• Firewall configurations
• Security Monitoring Reports
• Visitor Records

Common Audit Findings

• Weak physical security controls
• Inadequate network monitoring
• Missing security documentation
• Unpatched systems
• Poor visitor management practices

The lack of strong security controls puts organizations at operational, regulatory, and reputational risks. The management of security controls keeps systems and information safe, unaltered, and accessible.

Skills Auditors Need to Master ITGC Reviews

To perform the ITGC review competently, professionals will need to master IT risks, internal controls, the basics of cybersecurity, and the documentation of audits. Practical knowledge of laws and data governance, as well as the management of identities, access, and changes, will also be necessary. The ability of auditors to assess the effectiveness of controls and suggest improvements is greatly enhanced by practical knowledge of audit testing.

The Appeal of ITGC

As IT becomes the forefront of service and products, the need for ITGC will grow. ITGC offers a competitive advantage to professionals in auditing, risk services, governance, regulatory services, compliance, and cybersecurity.
