This CRISC practice question tests your understanding of it risk identification. 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.
A multinational organization uses a third-party vendor for cloud-based identity management. The vendor recently suffered a data breach that exposed user credentials. The risk manager is now re-evaluating the associated risk. Which of the following steps should the risk manager perform FIRST to identify potential new risks?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Update the risk register to include the new threat scenario of credential compromise via the vendor.
Option D is correct because updating the risk register with the new incident information is the first step to ensure all risks are captured. Option A (contract review) is important but secondary. Option B (penetration test) may be reactive but not immediate first step. Option C (access reviews) is a control, not risk identification.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Review the contract to determine if the vendor is liable for the breach.
Why it's wrong here
Contract review is important but should follow identification and assessment of new risks.
✓
Update the risk register to include the new threat scenario of credential compromise via the vendor.
Why this is correct
Updating the risk register is the first step in risk identification after a new event.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
Immediately revoke all vendor access to internal systems.
Why it's wrong here
Revoking access may be a reactive control, not a risk identification step.
✗
Conduct a penetration test of the organization's own systems.
Why it's wrong here
This focuses internally, but the risk is from the vendor, so testing vendor systems is not under the organization's control.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related CRISC NAT questions on configuration and troubleshooting.

What is the correct answer to this question?
The correct answer is: Update the risk register to include the new threat scenario of credential compromise via the vendor. — Option D is correct because updating the risk register with the new incident information is the first step to ensure all risks are captured. Option A (contract review) is important but secondary. Option B (penetration test) may be reactive but not immediate first step. Option C (access reviews) is a control, not risk identification.
What should I do if I get this CRISC question wrong?

Are there clue words in this question I should notice?
Yes — watch for: "first". Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
What is the key concept behind this question?
Static NAT maps one inside address to one outside address.
