SSCP Practice Question: A security team uses a risk matrix with…
A security team uses a risk matrix with likelihood (Low, Medium, High) and impact (Low, Medium, High). A vulnerability scan finds a buffer overflow in a customer-facing web application. The application is not critical but has high availability requirements. The likelihood of exploitation is considered Medium due to internal network segmentation. What is the risk level?
⚠ Common exam trap
ISC2 often tests the misconception that internal network segmentation automatically lowers the risk to Medium or Low, but the high availability requirement elevates the impact, resulting in a High risk level despite the reduced likelihood.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
High
The risk level is High because the likelihood is Medium (due to internal network segmentation reducing but not eliminating the chance of exploitation) and the impact is High (the application has high availability requirements, so a buffer overflow could cause a denial of service or code execution, severely affecting availability). In a standard 3x3 risk matrix, Medium likelihood combined with High impact yields a High risk rating.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Medium
Why it's wrong here
Combination of Medium likelihood and High impact typically yields High, not Medium.
- ✗
Extreme
Why it's wrong here
The matrix only has Low, Medium, High levels.
- ✓
High
Why this is correct
Standard 3x3 risk matrix: Medium likelihood + High impact = High risk.
- ✗
Low
Why it's wrong here
Impact is High due to availability requirement, so risk cannot be Low.
