The answer is the exposure of POS system API keys stored in plain text on the inventory SaaS server. This represents the highest risk because it is a confirmed technical control failure—plain-text API keys violate the company’s encryption-at-rest policy and create an active, exploitable vulnerability. An attacker who gains access to these keys can impersonate the POS system, intercept or manipulate credit card transactions, and compromise the entire payment pipeline, making this an immediate, high-impact threat rather than a mere procedural gap. On the CRISC exam, this scenario tests your ability to prioritize confirmed control failures over missing policies or legal agreements, a common trap where candidates focus on the lack of an NDA instead of the active exposure. Remember the memory tip: “Plain text keys are a direct breach; missing NDAs are just a paper weakness.”
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 mid-sized retail company operates 50 stores across three regions. Each store uses a point-of-sale (POS) system that transmits credit card transactions to a centralized payment processor. The company recently deployed a new SaaS-based inventory management application that connects to the POS system via API. The IT department has no formal process for tracking third-party connections. The risk manager suspects that unknown or unauthorized connections may exist. During a risk identification review, the risk manager discovers that the POS vendor's API documentation was shared with the inventory SaaS provider without a non-disclosure agreement (NDA). Additionally, the API keys for the POS system are stored in plain text configuration files on the inventory SaaS application server. The company's security policy requires encryption of all sensitive data in transit and at rest. Which of the following should the risk manager prioritize as the HIGHEST risk scenario to document in the risk register?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Exposure of POS system API keys stored in plain text on the inventory SaaS server
The plain-text storage of API keys on the inventory SaaS server represents an active, exploitable vulnerability that directly violates the company's encryption-at-rest policy. Unlike the other options, this is a confirmed technical control failure that could allow an attacker to impersonate the POS system, intercept or manipulate credit card transactions, and compromise the entire payment processing pipeline. The risk is immediate and high-impact because the keys are already exposed, not merely a procedural gap or missing legal agreement.
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.
✓
Exposure of POS system API keys stored in plain text on the inventory SaaS server
Why this is correct
Direct exposure of credentials that access payment systems, leading to high risk of data breach.
Related concept
Read the scenario before looking for a memorised answer.
✗
The POS system may not be PCI DSS compliant due to API sharing without NDA
Why it's wrong here
Compliance is a subset but the plain text keys pose operational risk.
✗
No formal process for tracking third-party connections
Why it's wrong here
Underlying issue but not the immediate risk; contributes to other risks.
✗
The lack of an NDA with the inventory SaaS provider
Why it's wrong here
Important but does not directly expose sensitive data; can be remediated later.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often prioritize procedural or compliance gaps (like missing NDAs or lack of formal processes) over a concrete, exploitable technical vulnerability, failing to recognize that a realized risk with immediate impact must be documented before addressing root causes.
Detailed technical explanation
How to think about this question
API keys stored in plain text on an application server can be extracted via local file inclusion (LFI), directory traversal, or server-side request forgery (SSRF) attacks. Once obtained, an attacker can use the keys to make authenticated API calls to the POS system, potentially initiating unauthorized transactions, exfiltrating customer payment data, or modifying inventory records. In real-world breaches, such as the 2018 Panera Bread incident, exposed API keys in configuration files led to mass data exfiltration of customer records.

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.
