CISM Information Security Programme Practice Question
A security manager needs to justify an increase in the security budget. Which metric is MOST compelling to demonstrate the value of security investments to the board?
⚠ Common exam trap
CISM often tests the difference between activity metrics (phishing simulations, tools deployed) and outcome/value metrics (ROI from avoided breach costs); candidates may pick activity metrics because they are easy to measure, but the board cares about financial impact.

Correct answer & explanation
✓
Return on investment (ROI) from avoided breach costs
Return on investment (ROI) from avoided breach costs translates security spending into financial terms that the board understands, showing how investments prevent losses. This metric directly ties security to business value by quantifying the cost avoidance from prevented incidents, which is more compelling than activity-based metrics. Boards are accountable for financial performance and risk, so ROI resonates with their fiduciary responsibilities.
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 phishing simulations conducted
Why it's wrong here
Phishing simulation counts measure activity volume, not risk reduction or financial impact, so they fail to demonstrate value to a board. It is tempting because simulations are easy to quantify and show engagement, but they would suit an awareness-programme progress report rather than budget justification.
- ✗
Percentage of IT budget allocated to security
Why it's wrong here
Budget share is an input measure showing spend ratio, not the risk reduction or loss avoidance that justifies additional funding. It is tempting because boards routinely review budget allocations and benchmarking against peers, yet the figure cannot show whether security investment is delivering measurable improvement.
- ✓
Return on investment (ROI) from avoided breach costs
Why this is correct
ROI from avoided breach costs translates security spending into financial terms the board already uses for capital decisions. This satisfies the stem by expressing value as quantifiable monetary return, making the budget request directly comparable to other investment proposals.
- ✗
Number of security tools deployed
Why it's wrong here
Tool counts measure activity and spending, not risk reduction, so they fail to demonstrate value to a board focused on exposure and loss. The metric is tempting because deployed tooling is easy to count and often cited in operational reporting, but it says nothing about whether controls actually reduce risk.
