質問 # 195
An analyst determines a security incident has occurred Which of the following is the most appropnate NEXT step in an incident response plan?
- A. Consult the data classification process
- B. Consult the communications plan
- C. Consult the malware analysis process
- D. Consult the disaster recovery plan
正解：B
解説：
A communications plan is a document that outlines who should be notified and how during an incident response. It can also specify the roles and responsibilities of the incident response team members, the escalation procedures, and the communication channels. Consulting the communications plan is the most appropriate next step in an incident response plan after determining a security incident has occurred. Consulting the malware analysis process, the disaster recovery plan, or the data classification process may be relevant at later stages of the incident response, but not as the next step.

質問 # 200
A company's legal department is concerned that its incident response plan does not cover the countless ways security incidents can occur. The department has asked a security analyst to help tailor the response plan to provide broad coverage for many situations. Which of the following is the best way to achieve this goal?
- A. Focus on incidents that have a high chance of reputation harm.
- B. Focus on common attack vectors first.
- C. Focus on incidents that may require law enforcement support.
- D. Focus on incidents that affect critical systems.
正解：D
解説：
An incident response plan should cover the most important and likely scenarios that could compromise the security and operations of an organization. According to various sources of best practices123, an incident response plan should start by conducting a risk assessment to identify potential threats and vulnerabilities, and prioritize the critical systems that need to be protected and restored in case of an incident. Focusing on incidents that affect critical systems ensures that the incident response plan covers the most severe and impactful situations that could harm the organization's mission, reputation, or legal obligations.

質問 # 202
Which of the following describes the mam difference between supervised and unsupervised machine-learning algorithms that are used in cybersecurity applications?
- A. Supervised algorithms require security analyst feedback, while unsupervised algorithms do not.
- B. Unsupervised algorithms are not suitable for IDS systems, white supervised algorithms are
- C. Unsupervised algorithms produce more false positives. Than supervised algorithms.
- D. Supervised algorithms can be used to block attacks, while unsupervised algorithms cannot.
正解：A
解説：
Supervised and unsupervised machine-learning algorithms are two types of machine-learning methods that are used in cybersecurity applications. Machine learning is a branch of artificial intelligence that enables systems to learn from data and improve their performance without explicit programming.
Supervised machine-learning algorithms are trained on labeled data, which means that each data point has a known outcome or class. Supervised algorithms learn to map input data to output data by finding patterns or rules from the training data. Supervised algorithms require security analyst feedback to provide labels for the data and evaluate the accuracy of the algorithm's predictions. Examples of supervised machine-learning algorithms are classification and regression.
Unsupervised machine-learning algorithms are trained on unlabeled data, which means that each data point has no known outcome or class. Unsupervised algorithms learn to discover hidden structures or patterns from the data without any guidance or feedback. Unsupervised algorithms do not require security analyst feedback, as they do not rely on predefined labels or outcomes. Examples of unsupervised machine-learning algorithms are clustering and anomaly detection.
