What are ITGCs | ManageEngine ADManager Plus
IT general controls (ITGCs) refer to the foundational controls that apply across an organization's IT environment to ensure the integrity, security, and reliability of information systems. They support the proper development and functioning of application controls and help ensure the overall control environment is sound.
These controls are broad in their scope and affect all systems and users across the organization. They typically include policies, procedures, and activities related to system access, operations, change management, and data backup.
Why are ITGCs important?
ITGCs form the baseline of internal control in IT systems. Without them, even the best application-level controls may be rendered ineffective. Their importance is evident in the areas mentioned below.
- Regulatory requirements: ITGCs are required to satisfy compliance standards and frameworks like the GDPR, SOX, HIPAA, ISO 27001, and NIST.
- Audit readiness: Auditors assess ITGCs to determine whether they can rely on an organization's IT systems during financial or compliance audits.
- Security and risk management: Effective ITGCs reduce the risk of unauthorized access, fraud, data breaches, and operational errors.
- Business continuity: ITGCs support resilience through data backup, disaster recovery, and system integrity measures.
Core categories of ITGCs
There are several core categories of ITGCs, each targeting a critical aspect of system management and security.
- Access controls
These controls ensure that only authorized individuals have access to IT systems and data, based on the roles and responsibilities assigned to them.
- Change management controls
Change management controls govern how modifications to systems, applications, and infrastructure are introduced.
- Segregation of Duties (SoD)
SoD ensures that critical tasks are divided among different people to prevent conflicts of interest, fraud, or errors.
- System operations controls
These controls are associated with the day-to-day functioning and maintenance of IT systems.
- Backup and recovery controls
These controls ensure that data is regularly backed up and can be recovered in case of disasters or failures.
- Audit logging and monitoring
These controls ensure that all system activities are logged and monitored for suspicious or unauthorized behavior.
How are ITGCs different from application controls?
Although ITGCs and application controls may sound similar, they are different when it comes to their scope.
- ITGCs apply across systems and processes and ensure the overall IT environment is controlled and secure.
- Application controls are specific to individual applications and focus on processing accuracy, completeness, and validity (for example, in the case of input validation).
Both are necessary to maintain the security posture of an organization, but ITGCs provide the structure in which application controls can operate effectively.
ITGC and compliance regulations
| Compliance regulation | How it relates to ITGCs | Key ITGC areas impacted | What do auditors look for |
|---|---|---|---|
| Sarbanes-Oxley Act (SOX) | Ensures financial data accuracy through reliable IT systems | Access controls, change management, audit logging, and SoD | Evidence of restricted access to financial systems, proper change approvals, and audit trails of modifications |
| Health Insurance Portability and Accountability Act (HIPAA) | Protects the integrity and confidentiality of electronic protected health information (ePHI) | Access controls, audit logging, system operations, backup and recovery | Role-based access to patient data, records of access attempts, and disaster recovery readiness |
| General Data Protection Regulation (GDPR) | Requires organizations to safeguard personal data and demonstrate accountability | Access controls, audit logging, backup and recovery | Controlled access to personal data, breach detection capabilities, and rights to access/modification logs |
| Payment Card Industry Data Security Standard (PCI DSS) | Ensures secure handling of credit card data and related information systems | Access controls, audit logging, and change management | Restricted access to cardholder data, real-time activity monitoring, and formal change control processes |
| Control Objectives for Information and Related Technologies (COBIT) | Framework for IT governance and management that emphasizes aligning IT with business goals | All ITGCs, especially SoD and change control | Governance structures, control activities, and performance metrics tied to IT risks |
Challenges in implementing ITGCs
Although ITGCs are important for maintaining the security posture of an organization, it can come with challenges such as:
- Lack of centralized visibility into access and changes.
- Manual and error-prone audit preparation.
- Difficulty maintaining consistency across hybrid or cloud environments.
- Limited staff expertise in governance controls.
