システム管理者は境界ファイアウォールを設定しましたが、内部エンドポイント間の疑わしい接続が引き続き発生しています。疑わしいアクティビティによる脅威を軽減するには、次のうちどれを設定する必要がありますか?
- A. アプリケーション許可リスト
- B. ホストベースのファイアウォール
- C. Web アプリケーション ファイアウォール
- D. アクセス制御リスト
正解：B
解説：
A host-based firewall is a software application that runs on an individual endpoint and filters the incoming and outgoing network traffic based on a set of rules. A host-based firewall can help to mitigate the threat posed by suspicious connections between internal endpoints by blocking or allowing the traffic based on the source, destination, port, protocol, or application. A host-based firewall is different from a web application firewall, which is a type of firewall that protects web applications from common web-based attacks, such as SQL injection, cross-site scripting, and session hijacking. A host-based firewall is also different from an access control list, which is a list of rules that control the access to network resources, such as files, folders, printers, or routers. A host-based firewall is also different from an application allow list, which is a list of applications that are authorized to run on an endpoint, preventing unauthorized or malicious applications from executing.

- A. エグゼクティブホエール
- B. メールフィッシング
- C. 内部脅威
- D. ソーシャルエンジニアリング
正解：D
解説：
Social engineering is the practice of manipulating people into performing actions or divulging confidential information, often by impersonating someone else or creating a sense of urgency or trust. The suspicious caller in this scenario was trying to use social engineering to trick the user into giving away credit card information by pretending to be the CFO and asking for a payment. The user recognized this as a potential scam and reported it to the IT help desk. The other topics are not relevant to this situation.

質問 # 20
システム管理者は、クラウドベースの低コストのアプリケーション ホスティング ソリューションを探しています。
次のどれがこれらの要件を満たしていますか?
- A. Serverless framework
- B. SDN
- C. Type 1 hvpervisor
- D. SD-WAN
正解：A
解説：
A serverless framework is a cloud-based application-hosting solution that meets the requirements of low-cost and cloud-based. A serverless framework is a type of cloud computing service that allows developers to run applications without managing or provisioning any servers. The cloud provider handles the server-side infrastructure, such as scaling, load balancing, security, and maintenance, and charges the developer only for the resources consumed by the application. A serverless framework enables developers to focus on the application logic and functionality, and reduces the operational costs and complexity of hosting applications.
Some examples of serverless frameworks are AWS Lambda, Azure Functions, and Google Cloud Functions.
A type 1 hypervisor, SD-WAN, and SDN are not cloud-based application-hosting solutions that meet the requirements of low-cost and cloud-based. A type 1 hypervisor is a software layer that runs directly on the hardware and creates multiple virtual machines that can run different operating systems and applications. A type 1 hypervisor is not a cloud-based service, but a virtualization technology that can be used to create private or hybrid clouds. A type 1 hypervisor also requires the developer to manage and provision the servers and the virtual machines, which can increase the operational costs and complexity of hosting applications.
Some examples of type 1 hypervisors are VMware ESXi, Microsoft Hyper-V, and Citrix XenServer.
SD-WAN (Software-Defined Wide Area Network) is a network architecture that uses software to dynamically route traffic across multiple WAN connections, such as broadband, LTE, or MPLS. SD-WAN is not a cloud- based service, but a network optimization technology that can improve the performance, reliability, and security of WAN connections. SD-WAN can be used to connect remote sites or users to cloud-based applications, but it does not host the applications itself. Some examples of SD-WAN vendors are Cisco, VMware, and Fortinet.
SDN (Software-Defined Networking) is a network architecture that decouples the control plane from the data plane, and uses a centralized controller to programmatically manage and configure the network devices and traffic flows. SDN is not a cloud-based service, but a network automation technology that can enhance the scalability, flexibility, and efficiency of the network. SDN can be used to create virtual networks or network functions that can support cloud-based applications, but it does not host the applications itself. Some examples of SDN vendors are OpenFlow, OpenDaylight, and OpenStack.

質問 # 21
ある企業は、ランサムウェア攻撃に対する補償を削除することで、年間サイバー保険のコストを削減することを決定しました。
企業がこの決定を下す際に最も使用した分析要素は次のどれでしょうか?
- A. ARO
- B. 次回
- C. RTO
- D. MTBF
正解：A
解説：
ARO (Annualized Rate of Occurrence) is an analysis element that measures the frequency or likelihood of an event happening in a given year. ARO is often used in risk assessment and management, as it helps to estimate the potential loss or impact of an event. A company can use ARO to calculate the annualized loss expectancy (ALE) of an event, which is the product of ARO and the single loss expectancy (SLE). ALE represents the expected cost of an event per year, and can be used to compare with the cost of implementing a security control or purchasing an insurance policy.
The company most likely used ARO in making the decision to remove the coverage for ransomware attacks from its cyber insurance policy. The company may have estimated the ARO of ransomware attacks based on historical data, industry trends, or threat intelligence, and found that the ARO was low or negligible. The company may have also calculated the ALE of ransomware attacks, and found that the ALE was lower than the cost of the insurance policy. Therefore, the company decided to reduce the cost of its annual cyber insurance policy by removing the coverage for ransomware attacks, as it deemed the risk to be acceptable or manageable.
IMTTR (Incident Management Team Training and Readiness), RTO (Recovery Time Objective), and MTBF (Mean Time Between Failures) are not analysis elements that the company most likely used in making the decision to remove the coverage for ransomware attacks from its cyber insurance policy. IMTTR is a process of preparing and training the incident management team to respond effectively to security incidents. IMTTR does not measure the frequency or impact of an event, but rather the capability and readiness of the team. RTO is a metric that defines the maximum acceptable time for restoring a system or service after a disruption. RTO does not measure the frequency or impact of an event, but rather the availability and continuity of the system or service. MTBF is a metric that measures the average time between failures of a system or component. MTBF does not measure the frequency or impact of an event, but rather the reliability and performance of the system or component.

- A. プリテキスティング
- B. フィッシング
- C. ヴィッシング
- D. スミッシング
正解：D
解説：
Smishing is a type of phishing attack that uses text messages or common messaging apps to trick victims into clicking on malicious links or providing personal information. The scenario in the question describes a smishing attack that uses pretexting, which is a form of social engineering that involves impersonating someone else to gain trust or access. The unknown number claims to be the company's CEO and asks the employee to purchase gift cards, which is a common scam tactic. Vishing is a similar type of attack that uses phone calls or voicemails, while phishing is a broader term that covers any email-based attack.
質問 # 23
ある企業は、自社が導入しているソフトウェアが、そのソフトウェアを購入したベンダーからのものであることを確認したいと考えています。企業がこの情報を確認するための最適な方法は、次のどれですか。
- A. サンドボックス内でコードを実行します。
- B. ファイルのハッシュを生成します。
- C. 実行可能ファイル内で ASCII 文字列を検索します。
- D. コード署名を検証します。
正解：D
解説：
Validating the code signature is the best way to verify software authenticity, as it ensures that the software has not been tampered with and that it comes from a verified source. Code signatures are digital signatures applied by the software vendor, and validating them confirms the software's integrity and origin.
質問 # 24
従業員を異なる役割に割り当てることで不正行為を検出するために最も効果的なのは次のうちどれですか?
- A. 強制休暇
- B. 職務の分離
- C. ジョブローテーション
- D. 最小権限
正解：C
解説：
Job rotation is a strategy used in organizations to detect and prevent fraud by periodically assigning employees to different roles within the organization. This approach helps ensure that no single employee has exclusive control over a specific process or set of tasks for an extended period, thereby reducing the opportunity for fraudulent activities to go unnoticed. By rotating roles, organizations can uncover irregularities and discrepancies that might have been concealed by an employee who had prolonged access to sensitive functions. Job rotation also promotes cross-training, which can enhance the organization's overall resilience and flexibility.

質問 # 25
ある企業は、天候によるサーバールームの損傷やダウンタイムを懸念しています。
企業が考慮すべき事項は次のうちどれでしょうか?
- A. ロードバランサー
- B. 地理的分散
- C. クラスタリングサーバー
- D. オフサイトバックアップ
正解：B
解説：
Geographic dispersion is a strategy that involves distributing the servers or data centers across different geographic locations. Geographic dispersion can help the company to mitigate the risk of weather events causing damage to the server room and downtime, as well as improve the availability, performance, and resilience of the network. Geographic dispersion can also enhance the disaster recovery and business continuity capabilities of the company, as it can provide backup and failover options in case of a regional outage or disruption12.
The other options are not the best ways to address the company's concern:
Clustering servers: This is a technique that involves grouping multiple servers together to act as a single system. Clustering servers can help to improve the performance, scalability, and fault tolerance of the network, but it does not protect the servers from physical damage or downtime caused by weather events, especially if the servers are located in the same room or building3.
Load balancers: These are devices or software that distribute the network traffic or workload among multiple servers or resources. Load balancers can help to optimize the utilization, efficiency, and reliability of the network, but they do not prevent the servers from being damaged or disrupted by weather events, especially if the servers are located in the same room or building4.
Off-site backups: These are copies of data or files that are stored in a different location than the original source. Off-site backups can help to protect the data from being lost or corrupted by weather events, but they do not prevent the servers from being damaged or disrupted by weather events, nor do they ensure the availability or continuity of the network services.

質問 # 26
データ センターのセキュリティ管理は、データが適切に保護され、人命への配慮が考慮されていることを確認するために見直されています。管理の設定方法を最もよく表しているのは次のうちどれですか。
- A. ログ制御はオープンフェイルする必要があります。
- B. 論理セキュリティ制御はフェイルクローズする必要があります。
- C. リモート アクセス ポイントはフェイルクローズされる必要があります。
- D. 安全制御はフェイルオープンになるはずです。
正解：D
解説：
Safety controls are security controls that are designed to protect human life and physical assets from harm or damage. Examples of safety controls include fire alarms, sprinklers, emergency exits, backup generators, and surge protectors. Safety controls should fail open, which means that they should remain operational or allow access when a failure or error occurs. Failing open can prevent or minimize the impact of a disaster, such as a fire, flood, earthquake, or power outage, on human life and physical assets. For example, if a fire alarm fails, it should still trigger the sprinklers and unlock the emergency exits, rather than remain silent and locked. Failing open can also ensure that essential services, such as healthcare, transportation, or communication, are available during a crisis. Remote access points, logging controls, and logical security controls are other types of security controls, but they should not fail open in a data center. Remote access points are security controls that allow users or systems to access a network or a system from a remote location, such as a VPN, a web portal, or a wireless access point. Remote access points should fail closed, which means that they should deny access when a failure or error occurs.
Failing closed can prevent unauthorized or malicious access to the data center's network or systems, such as by hackers, malware, or rogue devices. Logging controls are security controls that record and monitor the activities and events that occur on a network or a system, such as user actions, system errors, security incidents, or performance metrics. Logging controls should also fail closed, which means that they should stop or suspend the activities or events when a failure or error occurs. Failing closed can prevent data loss, corruption, or tampering, as well as ensure compliance with regulations and standards. Logical security controls are security controls that use software or code to protect data and systems from unauthorized or malicious access, modification, or destruction, such as encryption, authentication, authorization, or firewall. Logical security controls should also fail closed, which means that they should block or restrict access when a failure or error occurs. Failing closed can prevent data breaches, cyberattacks, or logical flaws, as well as ensure confidentiality, integrity, and availability of data and systems.

組織のクラウド導入戦略を検討しながら、最高情報セキュリティ責任者は、ファームウェア、オペレーティング システム、およびアプリケーションのパッチ適用を、選択したクラウド ベンダーにアウトソーシングするという目標を設定します。
次のどれがこの目標を最もよく満たしていますか?
- A. PaaS
- B. コンテナ化
- C. プライベートクラウド
- D. SaaS
- E. コミュニティクラウド
- F. aaS
正解：D
解説：
Software as a Service (SaaS) is the cloud model that best meets the goal of outsourcing the management, including patching, of firmware, operating systems, and applications to the cloud vendor. In a SaaS environment, the cloud provider is responsible for maintaining and updating the entire software stack, allowing the organization to focus on using the software rather than managing its infrastructure.

質問 # 28
次のトピックのうち、組織の SDLC に含まれる可能性が高いのはどれですか?
- A. 侵入テストの方法論
- B. ブランチ保護要件
- C. 情報セキュリティポリシー
- D. サービスレベル契約
正解：C
解説：
Within an organization's Software Development Life Cycle (SDLC), an Information Security Policy is a vital component. It outlines the rules and procedures for ensuring that the organization's IT assets and data are protected throughout the development process. Ensuring secure coding practices, access controls, and regular security testing is fundamental in preventing vulnerabilities in applications.
Other options like service-level agreements and branch protection requirements are less likely to be integral to SDLC processes. Penetration testing methodology, while useful, is generally considered outside the scope of the SDLC.
質問 # 29
従業員が侵害された業界ブログにアクセスした後、マルウェアが会社のネットワーク全体に広がりました。このタイプの攻撃を最もよく表すのは次のどれですか?
- A. なりすまし
- B. 水飲み場
- C. スミッシング
- D. 偽情報
正解：B
解説：
A watering-hole attack is a type of cyberattack that targets groups of users by infecting websites that they commonly visit. The attackers exploit vulnerabilities to deliver a malicious payload to the organization's network. The attack aims to infect users' computers and gain access to a connected corporate network. The attackers target websites known to be popular among members of a particular organization or demographic. The attack differs from phishing and spear-phishing attacks, which typically attempt to steal data or install malware onto users' devices1 In this scenario, the compromised industry blog is the watering hole that the attackers used to spread malware across the company's network. The attackers likely chose this blog because they knew that the employees of the company were interested in its content and visited it frequently. The attackers may have injected malicious code into the blog or redirected the visitors to a spoofed website that hosted the malware. The malware then infected the employees' computers and propagated to the network.

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
- C. パスワード監査に失敗しました
- D. 権限昇格
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.
質問 # 31

- D. デバイスが企業内の別の場所に移動されます。
- E. デバイスは承認された更新を受信できません。
- F. デバイスは実稼働環境からテスト環境に移動されました。
正解：A、B
解説：
B: The device is configured to use cleartext passwords. This is a major security vulnerability and poses a significant risk of unauthorized access. Devices using cleartext passwords should be decommissioned and replaced with devices using secure authentication methods.
E: The device's encryption level cannot meet organizational standards. If the device cannot encrypt data to the required level, it compromises the confidentiality of sensitive information and should be decommissioned. Organizational security policies should dictate the minimum acceptable encryption level for network devices.

セキュリティ アナリストがドメイン アクティビティ ログを確認し、次の点に気付きました。
セキュリティアナリストが発見した内容について、最も適切な説明は次のどれですか?
- A. 攻撃者が ismith のアカウントをブルートフォース攻撃しようとしています。
- B. [smithのワークステーションにキーロガーがインストールされています
- C. ドメインにランサムウェアが展開されました。
- D. ユーザー jsmith のアカウントがロックアウトされました。
正解：A
解説：
Brute force is a type of attack that tries to guess the password or other credentials of a user account by using a large number of possible combinations. An attacker can use automated tools or scripts to perform a brute force attack and gain unauthorized access to the account. The domain activity logs show that the user ismith has failed to log in 10 times in a row within a short period of time, which is a strong indicator of a brute force attack. The logs also show that the source IP address of the failed logins is different from the usual IP address of ismith, which suggests that the attacker is using a different device or location to launch the attack. The security analyst should take immediate action to block the attacker's IP address, reset ismith's password, and notify ismith of the incident.
