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. 最小権限
  • B. 職務の分離
  • C. ジョブローテーション
  • D. 強制休暇

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 # 68
セキュリティ エンジニアは、攻撃中に増加するさまざまなトラフィック タイプの影響を最小限に抑えるために NGFW を構成する必要があります。エンジニアが構成する可能性が高いルールのタイプは次のうちどれですか。

  • A. エージェントベース
  • B. URLベース
  • C. 署名ベース
  • D. 行動ベース

正解:D

解説:
To minimize the impact of the increasing number of various traffic types during attacks, a security engineer is most likely to configure behavioral-based rules on a Next-Generation Firewall (NGFW). Behavioral-based rules analyze the behavior of traffic patterns and can detect and block unusual or malicious activity that deviates from normal behavior.
Behavioral-based: Detects anomalies by comparing current traffic behavior to known good behavior, making it effective against various traffic types during attacks.
Signature-based: Relies on known patterns of known threats, which might not be as effective against new or varied attack types.
URL-based: Controls access to websites based on URL categories but is not specifically aimed at handling diverse traffic types during attacks.
Agent-based: Typically involves software agents on endpoints to monitor and enforce policies, not directly related to NGFW rules.


質問 # 69
ユーザーに証明書が提示されたときに、証明書を検証するために使用されるのは次のどれですか?

  • A. CSR
  • B. CA
  • C. CRC
  • D. OCSP

正解:D

解説:
OCSP stands for Online Certificate Status Protocol. It is a protocol that allows applications to check the revocation status of a certificate in real-time. It works by sending a query to an OCSP responder, which is a server that maintains a database of revoked certificates. The OCSP responder returns a response that indicates whether the certificate is valid, revoked, or unknown. OCSP is faster and more efficient than downloading and parsing Certificate Revocation Lists (CRLs), which are large files that contain the serial numbers of all revoked certificates issued by a Certificate Authority (CA).

  • A. なりすまし
  • B. 偽情報
  • C. スミッシング
  • D. 捕鯨

正解:A

解説:
Impersonating involves pretending to be someone else, in this case, the Chief Executive Officer (CEO), to deceive the employee into taking a specific action (buying gift cards). The attacker is leveraging the authority and trust associated with the CEO's position to manipulate the employee.
Whaling: This phishing attack targets high-profile individuals, such as executives.
An attacker is 'posing' and not 'targeting' a CEO.


質問 # 73
サポートが終了したソフトウェアを実行しているアプリケーション サーバーをネットワークの脅威から保護するための最も効果的な方法はどれですか?

  • A. バリケード
  • B. エアギャップ
  • C. ポートセキュリティ
  • D. スクリーンサブネット

正解:B

解説:
Air-gapping is the most effective way to protect an application server running unsupported software from network threats. By physically isolating the server from any network connection (no wired or wireless communication), it is protected from external cyber threats. While other options like port security or a screened subnet can provide some level of protection, an air gap offers the highest level of security by preventing any network-based attacks entirely.

質問 # 75
システム管理者は地元の病院に勤務しており、患者データが保護され、安全であることを確認する必要があります。患者データを保護するには、次のどのデータ分類を使用する必要がありますか?

  • A. プライベート
  • B. 敏感
  • C. パブリック
  • D. クリティカル

正解:B

解説:
Data classification is a process of categorizing data based on its level of sensitivity, value, and impact to the organization if compromised. Data classification helps to determine the appropriate security controls and policies to protect the data from unauthorized access, disclosure, or modification. Different organizations may use different data classification schemes, but a common one is the four-tier model, which consists of the following categories: public, private, sensitive, and critical.
Public data is data that is intended for public access and disclosure, and has no impact to the organization if compromised. Examples of public data include marketing materials, press releases, and public web pages.
Private data is data that is intended for internal use only, and has a low to moderate impact to the organization if compromised. Examples of private data include employee records, financial reports, and internal policies.
Sensitive data is data that is intended for authorized use only, and has a high impact to the organization if compromised. Examples of sensitive data include personal information, health records, and intellectual property.
Critical data is data that is essential for the organization's operations and survival, and has a severe impact to the organization if compromised. Examples of critical data include encryption keys, disaster recovery plans, and system backups.
Patient data is a type of sensitive data, as it contains personal and health information that is protected by law and ethical standards. Patient data should be used only by authorized personnel for legitimate purposes, and should be secured from unauthorized access, disclosure, or modification. Therefore, the systems administrator should use the sensitive data classification to secure patient data.

質問 # 76
セキュリティ管理者が最近ローカル パスワードをリセットしたところ、次の値がシステムに記録されました。

セキュリティ管理者が最も保護する可能性のあるものは何ですか?

  • A. パスザハッシュ攻撃
  • B. パスワード侵害
  • C. アカウント共有
  • D. パスワードの複雑さが弱い

正解:A

解説:
The scenario shows MD5 hashed password values. The most likely reason the security administrator is focusing on these values is to protect against pass-the-hash attacks. In this type of attack, an attacker can use a captured hash to authenticate without needing to know the actual plaintext password. By managing and monitoring these hashes, the administrator can implement strategies to mitigate this type of threat.

質問 # 77
セキュリティ アナリストは、コマンド アンド コントロール サーバーへの送信通信が疑われるワークステーションを調査しています。調査中に、エンドポイントのログが削除されていることがアナリストによって発見されました。
アナリストが次に確認する可能性が高いログは次のどれですか?

  • A. IPS
  • B. ファイアウォール
  • C. ACL
  • D. Windows セキュリティ

正解:B

解説:
Since the logs on the endpoint were deleted, the next best option for the analyst is to examine firewall logs. Firewall logs can reveal external communication, including outbound traffic to a command-and-control (C2) server. These logs would contain information about the IP addresses, ports, and protocols used, which can help in identifying suspicious connections.
IPS logs may provide information about network intrusions, but firewall logs are better for tracking communication patterns.
ACL logs (Access Control List) are useful for tracking access permissions but not for identifying C2 communication.
Windows security logs would have been ideal if they had not been deleted.


質問 # 78
トークン化を使用するデータ保護戦略の例は次のどれですか?

  • A. 機密データを含むデータベースの暗号化
  • B. 運用システムから機密データを削除する
  • C. 重要なシステム内の機密データのハッシュ化
  • D. 機密データを代替値に置き換える

正解:D

解説:
Detailed Explanation:
Tokenization replaces sensitive data with non-sensitive surrogate values that retain the necessary format but are meaningless without access to the original data. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 3: Security Architecture, Section: "Data Masking and Tokenization".


質問 # 79
インシデント対応の一環として根本原因分析を実施する必要がある理由を説明しているのはどれですか?

  • A. 同様の事件が今後起こらないようにするため
  • B. 影響を受けたシステムを見つける
  • C. 調査のための証拠を集める
  • D. ネットワーク上のマルウェアの痕跡を根絶する

正解:A

解説:
Root cause analysis is a process of identifying and resolving the underlying factors that led to an incident. By conducting root cause analysis as part of incident response, security professionals can learn from the incident and implement corrective actions to prevent future incidents of the same nature. For example, if the root cause of a data breach was a weak password policy, the security team can enforce a stronger password policy and educate users on the importance of password security. Root cause analysis can also help to improve security processes, policies, and procedures, and to enhance security awareness and culture within the organization. Root cause analysis is not meant to gather loCs (indicators of compromise) for the investigation, as this is a task performed during the identification and analysis phases of incident response. Root cause analysis is also not meant to discover which systems have been affected or to eradicate any trace of malware on the network, as these are tasks performed during the containment and eradication phases of incident response. Reference = CompTIA Security+ SY0-701 Certification Study Guide, page 424-425; Professor Messer's CompTIA SY0-701 Security+ Training Course, video 5.1 - Incident Response, 9:55 - 11:18.

質問 # 81
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. SD-WAN
  • B. Type 1 hvpervisor
  • C. Serverless framework
  • D. SDN

正解:C

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.
