Top 3 Key Performance Indicators (KPIs) for an Information Security Program
Which THREE of the following are key performance indicators (KPIs) for an information security program?
Quick Answer
The answer is Mean time to respond (MTTR) to incidents, along with vulnerability remediation rate and security awareness training completion. These three are correct because key performance indicators for an information security program must measure the effectiveness and efficiency of security processes, not just the presence of resources. MTTR directly reflects how quickly the program can contain and mitigate threats, while remediation rate shows the speed of fixing weaknesses, and training completion indicates the human layer’s readiness. On the Certified Information Security Manager CISM exam, this question tests your ability to distinguish between performance metrics and resource counts—a common trap is selecting “number of firewalls,” which is an inventory measure, not a KPI. Remember that KPIs always answer “how well” the program is performing, not “how many” assets exist. A useful memory tip: think of the three Cs—Containment speed (MTTR), Correction speed (remediation), and Culture (training completion).
⚠ Common exam trap
ISACA CISM often tests the distinction between resource metrics (like staff count) and true performance indicators (like remediation rates or response times), and the trap here is that candidates mistake operational metrics (firewall rules) for program-level KPIs.

Correct answer & explanation
✓
Number of security awareness training completions per quarter.
The number of security awareness training completions per quarter directly measures the reach and effectiveness of the human-centric security program, which is a key driver for reducing phishing and social engineering risks. This KPI aligns with the NIST SP 800-50 framework for security awareness and training metrics, as it tracks behavioral adoption rather than just policy existence.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Number of security awareness training completions per quarter.
Why this is correct
Indicates program reach.
- ✗
Total number of security staff.
Why it's wrong here
Resource metric, not a performance indicator.
- ✓
Percentage of critical vulnerabilities remediated within SLA.
Why this is correct
Shows control effectiveness.
- ✗
Average number of firewall rules per device.
Why it's wrong here
Does not reflect performance or outcomes.
- ✓
Mean time to respond (MTTR) to incidents.
Why this is correct
Measures operational effectiveness.

Variation 1. Which THREE are key performance indicators (KPIs) for an information security program?
hard- A.Number of security incidents
- ✓ B.Percentage of employees trained
- C.Budget variance
- ✓ D.Patch compliance rate
- ✓ E.Mean time to detect (MTTD)
Why B: The percentage of employees trained is a key performance indicator (KPI) because it directly measures the effectiveness of the security awareness program, which is a critical control to reduce human error—the leading cause of breaches. A high training completion rate correlates with lower phishing susceptibility and improved incident reporting, making it a leading indicator of program maturity.
