I think B

Even though you notify the third party in this case. Who else will be involved and the communication plan, what next everything is documented in org's IR policy.

I vote C. Privacy breach is a huge thing that elevates incident to another level. Since the questions states that company has outsourced its entire incident management capabilities, then the most important think it should do is to communicate to their incident management provider that privacy breach has occurred.

The company has outsourced it's incidence management capabilities so it wouldn't have an incident response plan; therefore the information security manager would notify the outsourcer of the privacy breach.

B. Refer to the organization's response plan It is crucial for the organization's information security manager to refer to the organization's own incident response plan first. This plan should outline the specific procedures and processes that the organization has established to respond to security incidents, including privacy breaches. Following the organization's response plan ensures that the incident is handled in alignment with the organization's internal policies, legal requirements, and best practices

in my opinion is B because I assume that inside the response plan (if the company has outsourced the incident management services) there is the process to involve the supplier

B. Refer to the organization's response plan

when faced with a significant privacy breach, the information security manager should first refer to the organization's own response plan to ensure a structured and effective response. Notifying the outsourcer of the privacy breach (option C) is an important step, as they may have a role in supporting the incident response efforts or have contractual obligations related to incident reporting. However, it should be done in accordance with the organization's own response plan and in a coordinated manner.

the organization should have its own response plan that outlines the specific steps and actions to be taken in the event of a privacy breach. This plan would provide guidance on how to handle the incident, including notifying the appropriate stakeholders, conducting an investigation, containing the breach, and implementing remedial measures. So Option B is the correct one

lOS DISPARADORES DEL PLAN PUEDEN ESTAR FUERA PERO EL PLAN ES DE LA ORGANIZACION, ISN IMPORTAR QUIEN LO GESTIONE

Option B is the correct answer in my opinion since C and D are would be a part of the Organization's Incident Response Plan.

The Correct Answer is (B) Refer to the organization's response plan. The first thing an organization should do is look at their incident response plan. Rationale: A. The organization can not outsource its responsibility to another organization. C. The outsourcer should only be contacted once the organization has been prepared and has a plan. D. Alert the appropriate law enforcement authorities should be part of the organization's incident response plan. This should be carefully evaluated cause once the organization calls the police the org loses control of the situation and thus should only be called once activated by the incident response plan.

First let them know about the situation, they will follow their incident respond plan. (i.e. Contact authorities)

Notifying the outsourcer of the privacy breach is certainly important, but it is not the most critical action in this scenario. The most important action for the information security manager would be to alert the appropriate law enforcement authorities. The reason for this is that a significant privacy breach by an unknown attacker may be a criminal act and requires immediate attention from law enforcement. Furthermore, reporting the incident to law enforcement can also help the organization gather information about the attacker, prevent further damage, and ensure the incident is properly investigated and resolved.
