- A
Conduct a forensic investigation to determine if any data was exfiltrated, then update the incident response plan.
Why wrong: Investigation is important but does not stop ongoing access.
- B
Immediately revoke the contractor's access and initiate a review of all contractor accounts to revoke any unnecessary permissions.
This directly mitigates the immediate risk of unauthorized access.
- C
Manually review access rights for all contractors and revoke those not needed, starting with the most sensitive systems.
Why wrong: Manual review is time-consuming and may not be immediate.
- D
Update the automated access review process to include all existing contractor accounts and schedule it to run weekly.
Why wrong: Policy change is a long-term fix, not an immediate response.
Quick Answer
The answer is to immediately revoke the contractor’s access and initiate a review of all contractor accounts to revoke any unnecessary permissions. This is correct because the immediate risk is an active, unauthorized access path to an S3 bucket containing PII, which directly violates GDPR’s Article 5(1)(f) on integrity and confidentiality. Revoking access stops the ongoing exposure, while the broader review addresses the systemic failure to apply the automated revocation process retroactively—a key principle of incident response for unauthorized access. On the CRISC exam, this scenario tests your ability to prioritize risk mitigation over investigation or policy creation; a common trap is choosing a forensic analysis step first, but the exam emphasizes that containment must precede any deeper review. Think of it as “stop the bleed before counting the wounds”—your first duty is to sever the active threat, then fix the process gap. Memory tip: “Revoke first, review second—containment before correction.”
CRISC IT Risk Assessment Practice Question
This CRISC practice question tests your understanding of it risk assessment. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
You are the IT risk manager for a multinational corporation with a hybrid cloud environment. The company uses AWS for its primary infrastructure and maintains an on-premises data center for legacy applications. Recently, the security team detected that a contractor's credentials were used to access an S3 bucket containing personally identifiable information (PII) of European customers. The contractor had been granted access to this bucket six months ago for a data migration project that has since been completed. The access was not revoked. The security team has implemented an automated process to review and revoke access for contractors after project completion, but this process has not been applied retroactively. The company is subject to GDPR. Which of the following is the BEST course of action to address the immediate risk?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"best"Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Clue:
"primary"Why it matters: Asks for the main purpose or function, not a secondary benefit. Eliminate answers that describe side-effects or partial functions.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Immediately revoke the contractor's access and initiate a review of all contractor accounts to revoke any unnecessary permissions.
The immediate risk is that the contractor still has active access to an S3 bucket containing PII, which violates GDPR's principle of data minimization and access control (Article 5(1)(f)). Revoking the contractor's access now stops any ongoing unauthorized access, and initiating a review of all contractor accounts addresses the systemic failure to apply the automated process retroactively. This directly mitigates the risk of further data exposure without delay.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may choose a forensic or process-improvement option (A or D) because they seem thorough, but the question asks for the BEST course of action to address the immediate risk, which is to stop the active unauthorized access first before investigating or improving long-term processes.
Detailed technical explanation
How to think about this question
In AWS, S3 bucket policies and IAM permissions are evaluated in real time; until the contractor's IAM user or role is revoked or the bucket policy is updated, the contractor retains programmatic access via the AWS CLI, SDK, or console. GDPR Article 32 requires appropriate technical measures to ensure ongoing confidentiality, and leaving orphaned access rights is a common finding in cloud audits. The automated process should use AWS IAM Access Analyzer or custom Lambda functions to regularly review and revoke unused or expired permissions, but retroactive application is critical to close existing gaps.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- 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 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.
