Question 410
An IS auditor is preparing recommendations after reviewing this situation: A team uses the same deployment credentials for development, test and production systems. Which recommendation would BEST address the identified weakness?
- Recommend distinct least-privileged release identities and controlled promotion rights.
- Recommend a proportionate emergency gate with tested rollback and follow-up review.
- Recommend benefit-gap analysis with assigned corrective owners and target dates.
- Recommend sponsor ownership and documented decision gates for regulatory and security issues.
Explanation
Correct Answer
A:Recommend distinct least-privileged release identities and controlled promotion rights. The relevant control principle is: Environment segregation supports authorization and limits unauthorized promotion risk. A meaningful follow-up should establish: A development credential cannot alter production while authorized releases succeed.
Incorrect Answers
B:Recommend a proportionate emergency gate with tested rollback and follow-up review. This would be relevant to a different issue such as: An emergency patch goes live without a rollback plan or verification of required interfaces. In the present case, the most directly relevant recommendation is: Recommend distinct least-privileged release identities and controlled promotion rights. The governing distinction is: Environment segregation supports authorization and limits unauthorized promotion risk.
C:Recommend benefit-gap analysis with assigned corrective owners and target dates. This would be relevant to a different issue such as: A new HR system meets its technical go-live date but fails the promised reduction in onboarding time. In the present case, the most directly relevant recommendation is: Recommend distinct least-privileged release identities and controlled promotion rights.
