SSCP Access Controls Practice Question
A company is implementing a biometric authentication system for physical access to a data center. The system must minimize false acceptances. Which metric is most directly related to false acceptance rate (FAR)?
Answer choices
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
✓
Threshold setting
FAR is the rate at which an unauthorized person is incorrectly accepted. The threshold setting directly impacts FAR; a higher (more stringent) threshold reduces FAR but may increase FRR.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Crossover error rate (CER)
Why it's wrong here
CER is where FAR equals FRR, not a direct measure of FAR.
- ✗
Equal error rate (EER)
Why it's wrong here
EER is another name for CER.
- ✗
False rejection rate (FRR)
Why it's wrong here
FRR is the opposite error; lowering FAR usually increases FRR.
- ✓
Threshold setting
Why this is correct
The threshold determines how closely a biometric sample must match the stored template; a stricter threshold lowers FAR.
