The answer is inadequate segregation of duties between development and production environments. This is the most significant control weakness because the developer bypassed the standard change approval process by making an emergency change directly to production, then retroactively documenting it as a normal change, which eliminates independent oversight and violates the core principle of segregation of duties. On the CISA exam, this scenario tests your ability to distinguish between a process failure and a fundamental control weakness—many candidates mistakenly focus on the lack of approval rather than the deeper issue of a single individual having both development and production access. A common trap is to select “inadequate change documentation” or “lack of emergency change policy,” but the real risk is that the same person who coded the change also controlled its deployment and audit trail. Memory tip: if one person can touch both the code and the live environment without a separate gatekeeper, think “SoD breach” first.
CISA Information System Auditing Process Practice Question
This CISA practice question tests your understanding of information system auditing process. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An IS auditor is reviewing a change management process. A developer made an emergency change directly to production without following the standard change approval process. The change was later documented as a normal change. Which control weakness is MOST indicated by this scenario?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Inadequate segregation of duties between development and production environments
The developer bypassed the standard change approval process by making an emergency change directly to production, then retroactively documenting it as a normal change. This directly violates the principle of segregation of duties (SoD), as the same individual who implemented the change also controlled the documentation and approval trail, eliminating independent oversight. In a properly segregated environment, developers should not have direct write access to production systems without a separate change authorization and deployment step.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Inadequate segregation of duties between development and production environments
Why this is correct
Direct production access by developers violates segregation of duties.
Related concept
Read the scenario before looking for a memorised answer.
✗
Absence of a rollback plan for emergency changes
Why it's wrong here
Rollback plans are relevant but not the primary weakness highlighted.
✗
Insufficient testing of emergency changes before deployment
Why it's wrong here
Testing is important, but the main issue is unauthorized access.
✗
Lack of a formal change documentation policy
Why it's wrong here
Documentation was done, though improperly categorized.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates focus on the lack of testing or documentation, but the most critical control weakness is the violation of segregation of duties, as the developer both made the change and controlled its documentation, eliminating independent oversight.
Detailed technical explanation
How to think about this question
Segregation of duties in change management typically requires that developers work in non-production environments (e.g., development or staging) and that a separate change advisory board (CAB) authorizes production deployments. In practice, emergency changes should follow a distinct, auditable path—often using a 'break-glass' procedure with post-implementation review—rather than being retroactively reclassified as normal changes. This scenario undermines the audit trail and can mask unauthorized code or configuration drift, which is a common finding in ITGC audits.

Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.

Variation 1. An IS auditor is evaluating the effectiveness of an organization's change management process. Which of the following is the most important control to verify during the audit?
easy
A.All changes are approved by the IT manager.
B.Emergency changes are documented after implementation.
✓ C.A segregation of duties exists between development and production.
D.Change requests are prioritized by business impact.
Why C: Segregation of duties between development and production environments ensures that code cannot be directly moved from development to production without independent review and testing. This control prevents unauthorized or untested code from affecting live systems, which is a fundamental principle of change management. Without this separation, a developer could introduce malicious or defective code directly into production, bypassing all quality and security checks.
