An organization is most likely to accept the risk of noncompliance with a new regulatory requirement when the cost of complying with the regulation exceeds the potential penalties. In such cases, from a cost-benefit perspective, the organization might find it more economical to absorb potential fines or penalties rather than implementing costly controls or processes to comply with the regulation.
"Risk acceptance occurs when the cost of mitigating or transferring the risk exceeds the benefit of the mitigation. This also applies to regulatory noncompliance if the penalties are less than the costs of compliance."
- CISM Review Manual 15th Edition, Chapter 2: Risk Management, Section: Risk Treatment Options* ISACA's practice questions highlight that risk acceptance is a legitimate treatment when costs outweigh potential penalties or impact.

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.

According to the Certified Information Security Manager (CISM) Study Manual, risk owners are responsible for managing a risk, including taking corrective action to reduce the risk to an acceptable level. When implementing controls, it is essential to obtain input from risk owners to ensure that the controls are effective in managing the risk to an acceptable level.
By obtaining input from risk owners, the organization can ensure that the controls are tailored to the specific risks and are effective in reducing the risk to an acceptable level. This can help to minimize the impact of the risk on the organization and reduce the potential for financial or reputational damage.

A business impact analysis (BIA) is a process that identifies and evaluates the potential effects of disruptions to critical business operations as a result of a disaster, accident or emergency. The primary purpose of a BIA is to determine the criticality of information assets and the impact of their unavailability on the organization's mission, objectives and reputation.
