Explanation
An incident response plan is a set of procedures and guidelines that define the roles and responsibilities of the incident response team, the steps to follow in the event of an incident, and the communication and escalation protocols to ensure timely and effective resolution of incidents. One of the essential components of an incident response plan is the criteria for escalation, which specify the conditions and thresholds that trigger the escalation of an incident to a higher level of authority or a different function within the organization. The criteria for escalation may depend on factors such as the severity, impact, duration, scope, and complexity of the incident, as well as the availability and capability of the incident response team. The criteria for escalation help to ensure that incidents are handled by the appropriate personnel, that management is kept informed and involved, and that the necessary resources and support are provided to resolve the incident.

Explanation
Obtaining senior management buy-in is the best way to enable the assignment of risk and control ownership because it helps to establish the authority and accountability of the risk and control owners, as well as to provide them with the necessary resources and support to perform their roles. Risk and control ownership refers to the assignment of specific responsibilities and accountabilities for managing risks and controls to individuals or groups within the organization. Obtaining senior management buy-in helps to ensure that risk and control ownership is aligned with the organizational objectives, structure, and culture, as well as to communicate the expectations and benefits of risk and control ownership to all stakeholders. Therefore, obtaining senior management buy-in is the correct answer.

Explanation:
It is easier to manage and control a centralized structure. Promoting security awareness is an advantage of decentralization. Decentralization allows you to use field security personnel as security missionaries or ambassadors to spread the security awareness message. Decentralized operations allow security administrators to be more responsive. Being close to the business allows decentralized security administrators to achieve a faster turnaround than that achieved in a centralized operation.
