= The contact list is the most important element of the escalation procedures for an incident response plan, as it ensures that the appropriate stakeholders are notified and involved in the incident management process. A contact list should include the names, roles, responsibilities, phone numbers, email addresses, and backup contacts of the key personnel involved in the incident response, such as the incident response team, senior management, legal counsel, public relations, law enforcement, and external service providers. The contact list should be regularly updated and tested to ensure its accuracy and availability123. References =

Complying with regulations regarding notification is the most important reason for an organization to communicate to affected parties that a security incident has occurred, as it helps to avoid legal penalties, fines, or sanctions that may result from failing to notify the relevant authorities, customers, or other stakeholders in a timely and appropriate manner. Additionally, complying with regulations regarding notification may also help to preserve the trust and reputation of the organization, as well as to facilitate the investigation and resolution of the incident.

Comprehensive and Detailed Step-by-Step Explanation:

Metrics should provide meaningful insights into the organization’s risk exposure and security performance. Evaluating this option:

A. The number of blocked external attacks is not representative of the true threat profile: This is the BEST answer because counting attacks blocked does not reveal the effectiveness of security controls or the real risk environment.

B. The number of blocked external attacks will vary by month, causing inconsistent graphs: While variability is a concern, it does not make the metric invalid.

C. The number of blocked external attacks is an indicator of the organization's popularity: This is true but irrelevant to assessing the effectiveness of security measures.

D. The number of blocked external attacks over time does not explain the attackers' motivations: Understanding motivations is useful but not directly tied to evaluating the firewall metric's effectiveness.

 = The information security manager should contact the information owner after the incident has been confirmed, as this is the first step of the incident response process. The information owner is the person who has the authority and responsibility for the information asset that is affected by the incident. The information owner needs to be informed of the incident as soon as possible, as they may have to make decisions or take actions regarding the protection, recovery, or restoration of the information asset. The information owner may also have to communicate with other stakeholders, such as the business units, customers, regulators, or media, depending on the nature and impact of the incident.

The other options are not the correct time to contact the information owner, as they occur later in the incident response process. Contacting the information owner after the incident has been contained, mitigated, or logged may delay the notification and escalation of the incident, as well as the involvement and collaboration of the information owner. Moreover, contacting the information owner after the incident has been contained or mitigated may imply that the incident response team has already taken actions that may affect the information asset without the consent or approval of the information owner. Contacting the information owner after a potential incident has been logged may cause unnecessary alarm or confusion, as the potential incident may not be a real or significant incident, or it may not affect the information owner’s asset. References =
