SecOps-Architect Operationalizing Security Metrics Practice Question
An architect is tasked with reporting the True Positive Rate (TPR) of automated alert rules in Cortex XSIAM to justify tuning efforts. How should TPR be calculated using SOC operational data?
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
✓
Verified True Positive Alerts divided by Total Triggered Alerts
True Positive Rate is calculated by dividing the number of verified true positive alerts by the total number of triggered alerts (or true positives plus false negatives, depending on the specific formula variant, but strictly using verified alerts vs total alerts generated).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Total False Positives divided by Total Closed Incidents
Why it's wrong here
This calculates the false positive ratio, not the true positive rate.
- ✗
Total Incidents Remediated divided by Total Hours Worked
Why it's wrong here
This measures analyst throughput or productivity, not alert detection accuracy.
- ✗
Mean Time to Resolve divided by Mean Time to Detect
Why it's wrong here
This ratio represents response efficiency, not detection accuracy.
- ✓
Verified True Positive Alerts divided by Total Triggered Alerts
Why this is correct
TPR measures the proportion of alerts that correctly identified a genuine security incident out of all generated alerts.
