The answer is to use a risk aggregation model to assess cumulative impact and consider enterprise-level controls. This is correct because risk aggregation for low individual risks addresses the fundamental principle that multiple negligible threats can compound into a significant exposure, a concept known as the "tyranny of small decisions." Treating each low-impact, low-probability item in isolation would miss the systemic vulnerability, whereas an aggregation model quantifies the combined effect, justifying enterprise-wide controls like shared security frameworks or centralized monitoring. On the CISM exam, this tests your understanding of risk treatment in the Risk Management domain, where a common trap is to accept or ignore low-level risks individually, forgetting that their accumulation can breach the organization’s risk appetite. A helpful memory tip is to think of "aggregate or aggravate"—if you don’t aggregate low risks, they will aggravate into a bigger problem.
CISM Information Security Risk Management Practice Question
This CISM practice question tests your understanding of information security risk management. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A risk manager is aggregating risks across the enterprise and finds that multiple individual risks, each with low impact and low probability, could combine to create a significant risk. What is the best approach to address this?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a risk aggregation model to assess cumulative impact and consider enterprise-level controls
Using a risk aggregation model allows the organization to assess the cumulative impact and implement enterprise-level controls. Ignoring or treating individually may miss the combined effect. Accepting as negligible ignores the potential for compounding.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Ignore the individual risks as they are low priority
Why it's wrong here
Ignoring risks prevents proper risk management.
✓
Use a risk aggregation model to assess cumulative impact and consider enterprise-level controls
Why this is correct
Aggregation provides a holistic view and appropriate mitigation.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Accept the risk because the probability of all occurring simultaneously is negligible
Why it's wrong here
The probability of combined occurrence may still be significant.
✗
Treat each individual risk separately with minimal controls
Why it's wrong here
This does not address the cumulative risk.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CISM exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
