セキュリティアナリストが次のログを確認しています:
次の攻撃のうち、最も発生する可能性が高いのはどれですか?
- A. アカウント偽造
- B. ハッシュを渡す
- C. ブルートフォース
- D. パスワードスプレー
正解：D
解説：
Password spraying is a type of brute force attack that tries common passwords across several accounts to find a match. It is a mass trial-and-error approach that can bypass account lockout protocols. It can give hackers access to personal or business accounts and information. It is not a targeted attack, but a high-volume attack tactic that uses a dictionary or a list of popular or weak passwords12.
The logs show that the attacker is using the same password ("password123") to attempt to log in to different accounts ("admin", "user1", "user2", etc.) on the same web server. This is a typical pattern of password spraying, as the attacker is hoping that at least one of the accounts has a weak password that matches the one they are trying. The attacker is also using a tool called Hydra, which is one of the most popular brute force tools, often used in cracking passwords for network authentication3.
Account forgery is not the correct answer, because it involves creating fake accounts or credentials to impersonate legitimate users or entities. There is no evidence of account forgery in the logs, as the attacker is not creating any new accounts or using forged credentials.
Pass-the-hash is not the correct answer, because it involves stealing a hashed user credential and using it to create a new authenticated session on the same network. Pass-the-hash does not require the attacker to know or crack the password, as they use the stored version of the password to initiate a new session4. The logs show that the attacker is using plain text passwords, not hashes, to try to log in to the web server.
Brute-force is not the correct answer, because it is a broader term that encompasses different types of attacks that involve trying different variations of symbols or words until the correct password is found. Password spraying is a specific type of brute force attack that uses a single common password against multiple accounts5. The logs show that the attacker is using password spraying, not brute force in general, to try to gain access to the web server.

質問 # 29
ウイルス、マルウェア、トロイの木馬がインストールされ、ネットワーク全体に広がるのを防ぐためにコンピュータを保護するために使用されるのは次のどれですか?
- A. ACL
- B. EDR
- C. IDS
- D. NAC
正解：B
解説：
Endpoint detection and response (EDR) is a technology that monitors and analyzes the activity and behavior of endpoints, such as computers, laptops, mobile devices, and servers. EDR can help to detect and prevent malicious software, such as viruses, malware, and Trojans, from infecting the endpoints and spreading across the network. EDR can also provide visibility and response capabilities to contain and remediate threats. EDR is different from IDS, which is a network-based technology that monitors and alerts on network traffic anomalies. EDR is also different from ACL, which is a list of rules that control the access to network resources. EDR is also different from NAC, which is a technology that enforces policies on the network access of devices based on their identity and compliance status.

質問 # 31
ある顧客がセキュリティ会社に、プロジェクトの概要、コスト、完了までの期間を記載した文書を提供するよう依頼しました。次の文書のうち、会社が顧客に提供すべきものはどれですか。
- A. SOW
- B. BPA
- C. MSA
- D. SLA
正解：A
解説：
An ISOW is a document that outlines the project, the cost, and the completion time frame for a security company to provide a service to a client. ISOW stands for Information Security Operations Work, and it is a type of contract that specifies the scope, deliverables, milestones, and payment terms of a security project. An ISOW is usually used for one-time or short-term projects that have a clear and defined objective and outcome. For example, an ISOW can be used for a security assessment, a penetration test, a security audit, or a security training. The other options are not correct because they are not documents that outline the project, the cost, and the completion time frame for a security company to provide a service to a client. A MSA is a master service agreement, which is a type of contract that establishes the general terms and conditions for a long-term or ongoing relationship between a security company and a client. A MSA does not specify the details of each individual project, but rather sets the framework for future projects that will be governed by separate statements of work (SOWs). A SLA is a service level agreement, which is a type of contract that defines the quality and performance standards for a security service provided by a security company to a client. A SLA usually includes the metrics, targets, responsibilities, and penalties for measuring and ensuring the service level. A BPA is a business partnership agreement, which is a type of contract that establishes the roles and expectations for a strategic alliance between two or more security companies that collaborate to provide a joint service to a client. A BPA usually covers the objectives, benefits, risks, and obligations of the partnership.
質問 # 32
管理者は、複数のユーザーが疑わしい IP アドレスからログインしていることに気付きました。ユーザーと話し合った後、管理者は従業員がそれらの IP アドレスからログインしていないことを確認し、影響を受けたユーザーのパスワードをリセットしました。管理者は、この種の攻撃が今後成功しないようにするために、次のどれを実施する必要がありますか?
- A. アクセス管理
- B. 多要素認証
- C. パスワードの複雑さ
- D. 権限の割り当て
正解：B
解説：
The correct answer is A because multifactor authentication (MFA) is a method of verifying a user's identity by requiring more than one factor, such as something the user knows (e.g., password), something the user has (e.g., token), or something the user is (e.g., biometric). MFA can prevent unauthorized access even if the user' s password is compromised, as the attacker would need to provide another factor to log in. The other options are incorrect because they do not address the root cause of the attack, which is weak authentication.
Permissions assignment (B) is the process of granting or denying access to resources based on the user's role or identity. Access management is the process of controlling who can access what and under what conditions. Password complexity (D) is the requirement of using strong passwords that are hard to guess or crack, but it does not prevent an attacker from using a stolen password. References = You can learn more about multifactor authentication and other security concepts in the following resources:

許容使用ポリシーは、次のセキュリティ制御タイプのうちどれを最もよく表していますか?
- A. 補償
- B. 抑止力
- C. 修正
- D. 予防的
正解：A
解説：
When a critical legacy server is segmented into a private network, the security control being used is compensating. Compensating controls are alternative measures put in place to satisfy a security requirement when the primary control is not feasible or practical. In this case, segmenting the legacy server into a private network serves as a compensating control to protect it from potential vulnerabilities that cannot be mitigated directly.
Compensating: Provides an alternative method to achieve the desired security outcome when the primary control is not possible.
Deterrent: Aims to discourage potential attackers but does not directly address segmentation.
Corrective: Used to correct or mitigate the impact of an incident after it has occurred.
Preventive: Aims to prevent security incidents but is not specific to the context of segmentation.

質問 # 37
セキュリティ オペレーション センターは、サーバー上で検出された悪意のあるアクティビティが正常であると判断します。
次のアクティビティのうち、検出されたアクティビティを将来無視する行為を説明しているものはどれですか?
- A. 集約
- B. アーカイブ
- C. 隔離中
- D. チューニング
正解：D
解説：
Tuning is the activity of adjusting the configuration or parameters of a security tool or system to optimize its performance and reduce false positives or false negatives. Tuning can help to filter out the normal or benign activity that is detected by the security tool or system, and focus on the malicious or anomalous activity that requires further investigation or response. Tuning can also help to improve the efficiency and effectiveness of the security operations center by reducing the workload and alert fatigue of the analysts. Tuning is different from aggregating, which is the activity of collecting and combining data from multiple sources or sensors to provide a comprehensive view of the security posture. Tuning is also different from quarantining, which is the activity of isolating a potentially infected or compromised device or system from the rest of the network to prevent further damage or spread. Tuning is also different from archiving, which is the activity of storing and preserving historical data or records for future reference or compliance. The act of ignoring detected activity in the future that is deemed normal by the security operations center is an example of tuning, as it involves modifying the settings or rules of the security tool or system to exclude the activity from the detection scope. Therefore, this is the best answer among the given options.

管理者が単一サーバーのセキュリティ ログを確認したところ、次のことが分かりました。
このログ ファイルに記録されたアクションを最もよく表すのは次のどれですか。
- A. ユーザーがパスワードを忘れた
- B. ブルートフォース攻撃
{<B> }: 権限昇格 - C. パスワード監査に失敗しました
正解：B
解説：
A brute-force attack is a type of attack that involves systematically trying all possible combinations of passwords or keys until the correct one is found. The log file shows multiple failed login attempts in a short amount of time, which is a characteristic of a brute-force attack.
The attacker is trying to guess the password of the Administrator account on the server. The log file also shows the event ID 4625, which indicates a failed logon attempt, and the status code
0xC000006A, which means the user name is correct but the password is wrong. These are indicators of compromise (IoC) that suggest a brute-force attack is taking place.

Counterfeit hardware is hardware that is built or modified without the authorization of the original equipment manufacturer (OEM). It can pose serious risks to network quality, performance, safety, and reliability12. Counterfeit hardware can also contain malicious components that can compromise the security of the network and the data that flows through it3. To address the risks associated with procuring counterfeit hardware, a company should conduct a thorough analysis of the supply chain, which is the network of entities involved in the production, distribution, and delivery of the hardware. By analyzing the supply chain, the company can verify the origin, authenticity, and integrity of the hardware, and identify any potential sources of counterfeit or tampered products. A thorough analysis of the supply chain can include the following steps:
Establishing a trusted relationship with the OEM and authorized resellers Requesting documentation and certification of the hardware from the OEM or authorized resellers Inspecting the hardware for any signs of tampering, such as mismatched labels, serial numbers, or components Testing the hardware for functionality, performance, and security Implementing a tracking system to monitor the hardware throughout its lifecycle Reporting any suspicious or counterfeit hardware to the OEM and law enforcement agencies Reference = 1: Identify Counterfeit and Pirated Products - Cisco, 2: What Is Hardware Security?

組織がデータ プライバシー プログラムを確立および維持する際に評価する上で最も重要な考慮事項は次のどれですか。
- A. コントローラーまたはプロセッサーとしての役割
- B. データプライバシー担当者の報告体制
- C. データ主体のアクセス要求プロセス
- D. 会社の所在地
正解：A
解説：
The most important consideration when establishing a data privacy program is defining the organization's role as a controller or processor. These roles, as outlined in privacy regulations such as the General Data Protection Regulation (GDPR), determine the responsibilities regarding the handling of personal data. A controller is responsible for determining the purpose and means of data processing, while a processor acts on behalf of the controller. This distinction is crucial for compliance with data privacy laws.
* Reporting structure for the data privacy officer is important, but it is a secondary consideration compared to legal roles.
* Request process for data subject access is essential for compliance but still depends on the organization's role as controller or processor.
* Physical location of the company can affect jurisdiction, but the role as controller or processor has a broader and more immediate impact.
