Exam CISM topic 1 question 131 discussion

Stop the attack from spreading -> C

My first answer was C but… from CISM Review Manual 16th Edition: Containment—After an incident has been identified and confirmed, the IMT is activated and information from the incident handler is shared. The team will conduct a detailed assessment and contact the system owner or business manager of the affected information systems/assets to coordinate further action. The action taken in this phase is to limit the exposure. Activities in this phase include:  Activating the IMT/IRT to contain the incident  Notifying appropriate stakeholders affected by the incident  Obtaining agreement on actions taken that may affect availability of a service or risk of the containment process

The Best answer remaining is C: because . notifying the relevant senior management personnel according to the organization's pre-defined escalation policy, providing details about the incident's nature, impact, and current response actions being taken. After the incident that has been verified, the security manager should "contain" the incident by isolating compromised systems, networks, or accounts to prevent further damage and preserve evidence, then move on to eradication and recovery phases to eliminate the threat and restore normal operations.

You need to contact the right people in order to see how you can contain. What if it's a production system that cannot be isolated or similar? First ask then act

If they had said what does an Information security manager do it would be to escalate to stakeholders but it says what would you do after the incident has been verified..i think it clearly is testing your awareness of the incident response process in this instance specifically. my opinion tho.

Although you do have to wear you "manager hat" for this exam, I'm gonna go with C here, as it seems to me that the question is basically asking about the steps/phases of incident response. The question explicitly says that you have identified and confirmed the incident taking place giving you the initial phase of IR and asking "what now?". Well, the next step is to contain it and stop it from doing further damage and only then you inform the appropriate people. Note that question is quite vague when defining the incident - we don't know what type of incident it is (is it a ransomware, is someone breaking AUP by taking photos inside the secure environment, etc). So that's why it is very tempting to select B. Again, going with C, but not 100% sure.

I think a common issue is people are thinking in technical terms. We have to think as a manager. The manager isn't stopping anything, they're directing people under them to do their job. So I would say B is correct

prevent further damage to the organization - then inform based on the incident response plan, escalation process and communication plan

Escalate and contain sometimes u need to escalate in order to contain

I thought B as well, but what if there was an incident confirmed in a credit card database, first step is to notify the data owner. And incident doesn't mean attack, there may be nothing to contain.

C. Prevent the incident from creating further damage to the organization. While all the options listed are important, preventing further damage is the top priority. Once the incident has been confirmed, it's crucial to take immediate steps to contain and mitigate the threat to minimize any additional harm to the organization's systems, data, and reputation. After containment and mitigation efforts are underway, you can then proceed with the other steps, such as notifying law enforcement, informing key stakeholders, and conducting a forensic investigation to determine the root cause.

Response B attending that the escalation process and communicated information allow the key stakeholders to assess the consequences of a containment on their operations. Otherwise response C is better.

Containment is the first step

The first phase after an incident has been detected is containment. Informing the required stakeholders according to the escalation procedures comes next.

On similar questions, when having a different phrasing for the general "incident" and stating explicitly "ransomware" the obvious answer was to contain the incident and prevent the incident from spreading

Containment

B. Follow the escalation process to inform key stakeholders.
