Automated monitoring of logs can also help identify the source, type, and impact of the DDoS attack, and provide evidence for further investigation or mitigation.
The other options are not as effective as automated monitoring of logs for detecting DDoS attacks. Customer service complaints are an indirect and delayed indicator of a DDoS attack, as they rely onusers reporting problems with accessing a website or service. Customer service complaints may also be caused by other factors unrelated to DDoS attacks, such as server errors or network issues. Server crashes are an extreme and undesirable indicator of a DDoS attack, as they indicate that the server has already been overwhelmed by the attack and has stopped functioning. Server crashes may also result in data loss or corruption, service disruption, or reputational damage. Penetration testing is a proactive and preventive measure for assessing the security posture of a system or network, but it does not detect ongoing DDoS attacks. Penetration testing may involve simulating DDoS attacks to test the resilience or vulnerability of a system or network, but it does not monitor real-time traffic or identify actual attackers.

CISA-KR 문제 542
Business owners are the individuals or entities who have the authority and responsibility to define the business needs and expectations for the project. They are also the primary beneficiaries of the project outcomes and benefits. Business owners play a crucial role in the project initiation phase, as they provide valuable input and feedback on the requirements and specifications of the project. Requirements are the statements that describe what the project should accomplish or deliver to meet the business needs and expectations. Requirements are essential for guiding the project planning, execution, monitoring, and closure phases.
If business owners are removed from the project initiation phase, it can result in incomplete or inaccurate requirements, which can have negative impacts on the project's quality, scope, time, cost, and risk. Some of the possible consequences of incomplete requirements are:
* Misalignment: The project may not align with the business strategy, vision, or goals, which can reduce its value or relevance.
* Confusion: The project team may not have a clear understanding of what the project should achieve or deliver, which can affect their performance or productivity.
* Rework: The project may need to undergo frequent changes or revisions to accommodate new or modified requirements, which can increase the time and cost of the project.
* Dissatisfaction: The project may not meet the expectations or satisfaction of the business owners or other stakeholders, which can affect their acceptance or support of the project.
* Failure: The project may not deliver the expected outcomes or benefits, which can affect its success or viability.
Therefore, an IS auditor should be concerned about the involvement and participation of business owners in the project initiation phase, as it affects the completeness and quality of requirements. An IS auditor should review the policies and procedures for stakeholder identification and engagement, verify that the business owners have adequate knowledge and skills to define their requirements, and test that the requirements are well-defined, documented, approved, and communicated.
