The answer is unauthorized access to patient medical records, which must be prioritized as the most critical risk from brute-force attacks on a patient portal. This is because a successful brute-force login directly compromises the confidentiality of protected health information (PHI), triggering severe HIPAA violation penalties and reputational damage, whereas denial of service or system slowdowns are secondary operational concerns. On the CRISC exam, this scenario tests your ability to distinguish between risk scenarios that threaten data confidentiality versus those affecting availability or integrity—a common trap is to focus on the brute-force attack’s immediate effect (like locking accounts) rather than its ultimate consequence of a data breach. Remember that for patient portals, the core risk is always PHI exposure, not service disruption. Memory tip: “Brute force on health data? Think breach, not block.”
CRISC IT Risk Identification Practice Question
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 hospital uses a patient portal that allows patients to access their medical records. The portal has experienced multiple brute-force login attempts. The risk manager wants to identify the most critical risk scenario. Which of the following should be prioritized?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Unauthorized access to patient medical records.
The most critical risk scenario from brute-force login attempts is unauthorized access to patient medical records, as this directly compromises patient privacy and violates HIPAA regulations. While denial of service is a concern, the primary impact of successful brute-force attacks is data breach, not service availability. The risk manager must prioritize the confidentiality of protected health information (PHI) over other operational risks.
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.
✗
Denial of service due to excessive login attempts.
Why it's wrong here
DoS is a concern but typically less impactful than data exposure.
✓
Unauthorized access to patient medical records.
Why this is correct
Breach of medical records can lead to legal penalties, identity theft, and harm to patients.
Related concept
Read the scenario before looking for a memorised answer.
✗
Insufficient encryption of data in transit.
Why it's wrong here
Encryption is a control issue, not the direct risk scenario from brute-force.
✗
Phishing attacks targeting portal users.
Why it's wrong here
The incident is brute-force, not phishing.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may focus on the immediate technical symptom (denial of service) rather than the primary business impact (unauthorized data access), which is the core of risk identification in CRISC.

Detailed technical explanation
How to think about this question
Brute-force attacks on a patient portal typically target the authentication endpoint, often using automated scripts to guess passwords against a REST API or web form. Successful credential compromise can lead to lateral movement within the hospital's network if the portal is integrated with backend systems like EHR databases (e.g., Epic or Cerner). Real-world incidents, such as the 2015 UCLA Health breach, show that brute-forced credentials can expose millions of patient records, leading to fines under HIPAA and reputational damage.

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.
