IT General Controls (ITGCs) (+4)

IT General Controls (ITGCs)

Controls over the IT environment that support the reliable functioning of application controls and automated processes.

Access Controls:

• User access provisioning (new access requests require approval)
• User access de-provisioning (terminated users removed timely)
• Privileged access management (admin/superuser access restricted and monitored)
• Periodic access reviews (user access recertified on a defined schedule)
• Password policies (complexity, rotation, lockout)
• Segregation of duties enforcement (conflicting access prevented)

Change Management:

• Change requests documented and approved before implementation
• Changes tested in a non-production environment before promotion
• Separation of development and production environments
• Emergency change procedures (documented, approved post-implementation)
• Change review and post-implementation validation

IT Operations:

• Batch job monitoring and exception handling
• Backup and recovery procedures (regular backups, tested restores)
• System availability and performance monitoring
• Incident management and escalation procedures
• Disaster recovery planning and testing

Manual Controls

Controls performed by people using judgment, typically involving review and approval.

Examples:

• Management review of financial statements and key metrics
• Supervisory approval of journal entries above a threshold
• Three-way match verification (PO, receipt, invoice)
• Account reconciliation preparation and review
• Physical inventory observation and count
• Vendor master data change approval
• Customer credit approval

Key attributes to test:

• Was the control performed by the right person (proper authority)?
• Was it performed timely (within the required timeframe)?
• Is there evidence of the review (signature, initials, email, system log)?
• Did the reviewer have sufficient information to perform an effective review?
• Were exceptions identified and appropriately addressed?

Automated Controls

Controls enforced by IT systems without human intervention.

Examples:

• System-enforced approval workflows (cannot proceed without required approvals)
• Three-way match automation (system blocks payment if PO/receipt/invoice don't match)
• Duplicate payment detection (system flags or blocks duplicate invoices)
• Credit limit enforcement (system prevents orders exceeding credit limit)
• Automated calculations (depreciation, amortization, interest, tax)
• System-enforced segregation of duties (conflicting roles prevented)
• Input validation controls (required fields, format checks, range checks)
• Automated reconciliation matching

Testing approach:

• Test design: Confirm the system configuration enforces the control as intended
• Test operating effectiveness: For automated controls, if the system configuration has not changed, one test of the control is typically sufficient for the period (supplemented by ITGC testing of change management)
• Verify change management ITGCs are effective (if system changed, re-test the control)

IT-Dependent Manual Controls

Manual controls that rely on the completeness and accuracy of system-generated information.

Examples:

• Management review of a system-generated exception report
• Supervisor review of a system-generated aging report to assess reserves
• Reconciliation using system-generated trial balance data
• Approval of transactions identified by a system-generated workflow

Testing approach:

• Test the manual control (review, approval, follow-up on exceptions)
• AND test the completeness and accuracy of the underlying report/data (IPE — Information Produced by the Entity)
• IPE testing confirms the data the reviewer relied on was complete and accurate

Entity-Level Controls

Broad controls that operate at the organizational level and affect multiple processes.

Examples:

• Tone at the top / code of conduct
• Risk assessment process
• Audit committee oversight of financial reporting
• Internal audit function and activities
• Fraud risk assessment and anti-fraud programs
• Whistleblower/ethics hotline
• Management monitoring of control effectiveness
• Financial reporting competence (staffing, training, qualifications)
• Period-end financial reporting process (close procedures, GAAP compliance reviews)

Significance:

• Entity-level controls can mitigate but typically cannot replace process-level controls
• Ineffective entity-level controls (especially audit committee oversight and tone at the top) are strong indicators of a material weakness
• Effective entity-level controls may reduce the extent of testing needed for process-level controls
