- A
Immediately implement a PCI DSS compliance program to ensure all payment data handling meets industry standards.
Why wrong: Compliance alone does not ensure effective detection and response.
- B
Develop and implement an incident response plan, establish a security operations center (SOC) with 24/7 monitoring, and define clear roles and responsibilities.
This addresses governance, detection, and response holistically.
- C
Purchase and deploy a next-generation firewall and endpoint detection and response (EDR) tools across the network.
Why wrong: Tools without processes and governance are insufficient.
- D
Outsource all security operations to a managed security service provider (MSSP) with a focus on threat intelligence.
Why wrong: Outsourcing without internal governance may lead to loss of control.
Quick Answer
The answer is to develop and implement an incident response plan, establish a security operations center (SOC) with 24/7 monitoring, and define clear roles and responsibilities. This is correct because the core governance failure here is the absence of a formal incident response framework and the 90-day detection gap, which a SOC with continuous monitoring directly closes. On the Certified Information Security Manager CISM exam, this scenario tests your understanding that incident response governance after a breach requires process and oversight, not just technology—a common trap is choosing a purely technical fix like patching the API, which ignores the systemic lack of accountability. The board’s concern about detection and response is a governance red flag, and defining roles ensures that ownership and escalation paths exist, aligning with CISM’s emphasis on aligning security with business objectives. Remember the mnemonic “Plan, Watch, Assign” to recall that governance after a breach demands a documented plan, continuous monitoring, and assigned responsibilities.
CISM Information Security Governance Practice Question
This CISM practice question tests your understanding of information security governance. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
You are the information security manager for a mid-sized e-commerce company with 500 employees. The company recently experienced a data breach where an attacker exploited a vulnerability in a third-party payment processing API, resulting in the exposure of 10,000 customer credit card numbers. The breach was detected by an external forensics team 90 days after the initial compromise. The board is concerned about the company's ability to detect and respond to incidents. Currently, the company has a part-time security team of three people who focus on firewall management and antivirus updates. There is no formal incident response plan, and security monitoring is limited to basic log review once a week. The CISO has asked you to recommend a course of action to improve the security posture, with a focus on governance and oversight. Which of the following is the BEST course of action?

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
Develop and implement an incident response plan, establish a security operations center (SOC) with 24/7 monitoring, and define clear roles and responsibilities.
Option B is correct because the core governance issue is the lack of a formal incident response plan and adequate monitoring. Establishing a SOC with 24/7 monitoring directly addresses the 90-day detection gap, while defining roles and responsibilities ensures accountability and oversight, which are key governance principles. This approach aligns with the CISM focus on establishing processes and oversight rather than just deploying technology.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose a technology-focused answer (like C or D) because it seems more concrete, but the CISM exam emphasizes that governance and oversight—such as having a formal plan and defined roles—must come before technology investments to ensure effective security management.
Detailed technical explanation
How to think about this question
A SOC with 24/7 monitoring typically uses a SIEM (Security Information and Event Management) system to aggregate logs from firewalls, servers, and applications, correlating events in near real-time to detect indicators of compromise (IoCs). The 90-day detection gap in this scenario highlights the need for continuous log analysis and alerting, which a basic weekly log review cannot provide. An incident response plan should include defined phases (preparation, detection, containment, eradication, recovery, and lessons learned) and assign specific roles such as incident commander, forensic analyst, and communications lead to ensure swift, coordinated action.
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.
TExam Day Tips
- 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.
