The answer is enforcing segregation of duties between development and production and requiring change management approval for all production changes. Segregation of duties prevents unauthorized changes by ensuring no single individual has the ability to both modify code and move it into production, creating a critical separation of responsibilities that blocks insider threats and accidental errors. Change management approval adds a formal gatekeeping layer, requiring every production change to be reviewed, authorized, and documented before implementation, which directly stops unauthorized modifications from reaching live data. On the CISA exam, this question tests your understanding of preventive controls within the change management and segregation of duties domains, often appearing as a trap where candidates mistakenly select detective controls like logging or monitoring. A common memory tip is to think of the “two gates” principle: who can touch the code versus who can let it through—if either gate is missing, unauthorized changes can slip past.
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.
Which TWO of the following are the MOST effective controls to prevent unauthorized changes to production data?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Requiring change management approval for all production changes
Requiring change management approval for all production changes is a preventive control that ensures every modification to production data is formally authorized, reviewed, and documented before implementation. This directly prevents unauthorized changes by enforcing a gatekeeping process where only approved changes proceed, reducing the risk of data integrity breaches. Without this control, even with other safeguards, an attacker or insider could bypass technical controls by simply requesting a change through official channels.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Implementing audit logging of all data changes
Why it's wrong here
Audit logs detect but do not prevent changes.
✗
Encrypting production data at rest
Why it's wrong here
Encryption protects confidentiality, not integrity.
✗
Using automated testing for all code changes
Why it's wrong here
Testing ensures quality but does not prevent unauthorized changes.
Common exam traps
Common exam trap: answer the scenario, not the keyword
ISACA often tests the distinction between preventive and detective controls, and the trap here is that candidates mistakenly choose audit logging (a detective control) as a preventive measure because it provides evidence of changes, but it does not stop unauthorized changes from occurring.
Detailed technical explanation
How to think about this question
Change management approval typically integrates with ITIL-based workflows and tools like ServiceNow or Jira Service Management, where a change advisory board (CAB) reviews risk, impact, and rollback plans before granting authorization. Under the hood, this control relies on role-based access control (RBAC) tied to the change management system, where production database write permissions are dynamically granted only after approval ticket closure. In a real-world scenario, a disgruntled DBA with direct database access could bypass change management if no approval gate exists, leading to data corruption or fraud.

→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CISA exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
