When integrating security risk management into an organization, it is most important to ensure that the risk management methodology follows an established framework, such as ISO 31000, NIST SP 800-30, or COBIT. This is because a framework provides a consistent and structured approach to identify, assess, treat, and monitor risks, and to align the risk management process with the organization’s objectives, culture, and governance. A framework also helps to ensure compliance with relevant standards and regulations, and to facilitate communication and reporting of risks to stakeholders.

Verified Answer: According to the CISM Review Manual, 15th Edition, Chapter 3, Section 3.2.1.3, "The appropriate risk treatment option is decided by the chief information security officer (CISO) or the designated risk owner."1

Comprehensive and Detailed Explanation: The CISO is the senior executive who is responsible for overseeing and managing the information security program of an organization. The CISO has the authority and expertise to assess the risks, determine the risk appetite and tolerance levels, and select the most suitable risk treatment options for each risk. The CISO also has the accountability and responsibility for implementing, monitoring, and reporting on the risk treatment activities.

Prevention of authorized access is the greatest threat posed by a distributed denial of service (DDoS) attack on a public-facing web server because it prevents legitimate users or customers from accessing the web services or resources, causing disruption, dissatisfaction, and potential loss of revenue or reputation. Execution of unauthorized commands is not a threat posed by a DDoS attack, but rather by a remote code execution (RCE) attack. Defacement of website content is not a threat posed by a DDoS attack, but rather by a web application attack. Unauthorized access to resources is not a threat posed by a DDoS attack, but rather by a brute force attack or an authentication bypass attack.

Recovery should not begin until the eradication phase is complete, meaning all malicious activity, malware, or unauthorized access has been removed. Starting recovery too early may reintroduce threats or result in re-infection.

“Recovery begins after eradication is complete, ensuring a clean environment for restoring services.”
