- A
Perform a root cause analysis on the firewall misconfigurations to determine underlying process weaknesses.
Root cause analysis systematically identifies the fundamental reason for the misconfigurations, such as inadequate change management.
- B
Implement additional logging on all firewall devices to capture configuration changes.
Why wrong: Logging alone does not perform analysis; it only records events.
- C
Conduct a penetration test targeting all regional office networks to identify vulnerabilities.
Why wrong: Penetration tests identify vulnerabilities, not process failures or root causes.
- D
Update the risk register to include the incidents and assign risk owners.
Why wrong: Updating the risk register is a subsequent step after identification, not a root cause identification method.
Quick Answer
The answer is to perform a root cause analysis on the firewall misconfigurations to determine underlying process weaknesses. This approach is correct because root cause analysis for IT risk identification digs past the immediate technical symptom—in this case, misconfigured firewall rules—to uncover the systemic process failures, such as a deficient change management workflow, that allowed the errors to occur repeatedly across multiple regional offices. On the Certified in Risk and Information Systems Control CRISC exam, this question tests your understanding that risk identification is not about finding vulnerabilities (which a penetration test would do) or increasing visibility (logging), but about tracing the chain of causation back to a broken control process. A common trap is to confuse a technical fix with a root cause; remember that the CRISC framework emphasizes process and governance over technology. Memory tip: think "RCA peels the onion"—each layer of symptom reveals a deeper process weakness, not just the outer technical layer.
CRISC IT Risk Identification Practice Question
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.
A multinational e-commerce company has experienced multiple security incidents involving unauthorized access to customer payment data. The incidents originated from different regional offices and exploited misconfigured firewall rules. The risk manager needs to identify the root cause of these risks. Which approach would BEST help in identifying the root cause of the IT risk?

Correct answer & explanation
Perform a root cause analysis on the firewall misconfigurations to determine underlying process weaknesses.
Option C is correct because conducting a root cause analysis on the firewall misconfigurations will identify the underlying weaknesses in the change management process. Option A is wrong because increasing logging without analysis does not identify root cause. Option B is wrong because a penetration test may find vulnerabilities but not the process failure. Option D is wrong because updating the risk register is a result of identification, not a method to identify root cause.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. 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?
hard- ✓ A.Implement infrastructure-as-code (IaC) security scanning and policy enforcement in the CI/CD pipeline to prevent insecure configurations.
- B.Deploy an intrusion detection system (IDS) to monitor database traffic for brute-force attempts.
- C.Hire a dedicated database administrator to review all database configurations weekly.
- D.Conduct quarterly security audits of cloud infrastructure configurations.
Why A: 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.
