This CRISC practice question tests your understanding of it risk identification. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 mid-sized e-commerce company that processes over 10,000 transactions per day. The company recently migrated its customer database from an on-premises SQL Server to a cloud-based PostgreSQL instance on AWS RDS. The database contains personally identifiable information (PII) including names, addresses, and credit card numbers (stored as encrypted tokens). The migration was performed by the DevOps team with minimal involvement from the security team. Two weeks after the migration, the company experienced a data breach where an attacker exfiltrated a subset of customer records. The forensic investigation revealed that the attacker exploited a misconfigured security group that allowed inbound traffic from the internet on port 5432 (PostgreSQL default port). Additionally, the database had a publicly accessible endpoint, and the master user password was weak (eight characters, no special characters). The attacker used a brute-force attack to guess the password. The security group has since been corrected, and the password has been changed to a strong one. The breach notification laws require reporting within 72 hours. The CEO wants to understand the root cause and prevent recurrence. As the risk manager, which of the following actions should you recommend as the MOST effective to prevent a similar incident?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement infrastructure-as-code (IaC) security scanning and policy enforcement in the CI/CD pipeline to prevent insecure configurations.
Option C is correct because the root cause is the misconfigured security group and weak password, both of which stem from insufficient security review and lack of automated controls. Implementing a policy-as-code tool that enforces security group rules (e.g., no public access to databases) and password policies during deployment would prevent such misconfigurations. Option A is wrong because while a dedicated DBA could help, it does not address the process gap for automated enforcement. Option B is wrong because quarterly reviews are too infrequent to catch misconfigurations quickly. Option D is wrong because IDS/IPS detects attacks but does not prevent misconfigurations.
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.
✓
Implement infrastructure-as-code (IaC) security scanning and policy enforcement in the CI/CD pipeline to prevent insecure configurations.
Why this is correct
Automated enforcement prevents misconfigurations from being deployed.
Related concept
Read the scenario before looking for a memorised answer.
✗
Deploy an intrusion detection system (IDS) to monitor database traffic for brute-force attempts.
Why it's wrong here
IDS detects but does not prevent the misconfiguration or weak password.
✗
Hire a dedicated database administrator to review all database configurations weekly.
Why it's wrong here
Weekly reviews are manual and may not catch misconfigurations in time.
✗
Conduct quarterly security audits of cloud infrastructure configurations.
Why it's wrong here
Quarterly audits are too infrequent to prevent incidents.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 CRISC 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.
