解説：
A dashboard is a graphical user interface that provides a visual representation of key performance indicators, metrics, and trends related to security events and incidents. A dashboard can help the board of directors to understand the number and impact of incidents that affected the organization in a given period, as well as the status and effectiveness of the security controls and processes. A dashboard can also allow the board of directors to drill down into specific details or filter the data by various criteria12.
A packet capture is a method of capturing and analyzing the network traffic that passes through a device or a network segment. A packet capture can provide detailed information about the source, destination, protocol, and content of each packet, but it is not a suitable way to present a summary of incidents to the board of directors13.
A vulnerability scan is a process of identifying and assessing the weaknesses and exposures in a system or a network that could be exploited by attackers. A vulnerability scan can help the organization to prioritize and remediate the risks and improve the security posture, but it is not a relevant way to report the number of incidents that occurred in a quarter14.
Metadata is data that describes other data, such as its format, origin, structure, or context. Metadata can provide useful information about the characteristics and properties of data, but it is not a meaningful way to communicate the impact and frequency of incidents to the board of directors. Reference = 1: CompTIA Security+ SY0-701 Certification Study Guide, page 3722: SIEM Dashboards - SY0-601 CompTIA Security+ : 4.3, video by Professor Messer3: CompTIA Security+ SY0-701 Certification Study Guide, page 3464: CompTIA Security+ SY0-701 Certification Study Guide, page 362. : CompTIA Security+ SY0-701 Certification Study Guide, page 97.
質問 # 128
セキュリティ アナリストは、業務時間外に短時間に大量の異常な DNS クエリをインターネット上のシステムに送信している内部システムに関するアラートを受け取ります。
次のどれが最も起こりそうですか?
- A. データが流出しています。
- B. ランサムウェアがファイルを暗号化しています。
- C. ワームがネットワーク全体に拡散しています。
- D. 論理爆弾がデータを削除しています。
正解：A
解説：
Data exfiltration is a technique that attackers use to steal sensitive data from a target system or network by transmitting it through DNS queries and responses. This method is often used in advanced persistent threat (APT) attacks, in which attackers seek to persistently evade detection in the target environment. A large amount of unusual DNS queries to systems on the internet over short periods of time during non-business hours is a strong indicator of data exfiltration. A worm, a logic bomb, and ransomware would not use DNS queries to communicate with their command and control servers or perform their malicious actions.
質問 # 129
次のセキュリティ概念のうち、RADIUS サーバーのインストールによって実現されるものはどれですか?
- A. ACL
- B. PEM
- C. CIA
- D. AAA
正解：D
解説：
The installation of a RADIUS server (Remote Authentication Dial-In User Service) is primarily associated with the security concept of AAA, which stands for Authentication, Authorization, and Accounting. RADIUS servers are used to manage user credentials and permissions centrally, ensuring that only authenticated and authorized users can access network resources, and tracking user activity for accounting purposes.
Authentication: Verifies the identity of a user or device. When a user tries to access a network, the RADIUS server checks their credentials (username and password) against a database.
Authorization: Determines what an authenticated user is allowed to do. After authentication, the RADIUS server grants permissions based on predefined policies.
Accounting: Tracks the consumption of network resources by users. This involves logging session details such as the duration of connections and the amount of data transferred.

質問 # 131
次のアラート タイプのうち、時間の経過とともに無視される可能性が最も高いのはどれですか?
- A. 真陰性
- B. 偽陰性
- C. 誤検知
- D. 真陽性
正解：C
解説：
A false positive is an alert that incorrectly identifies benign activity as malicious. Over time, if an alerting system generates too many false positives, security teams are likely to ignore these alerts, resulting in "alert fatigue." This increases the risk of missing genuine threats.
* True positives and true negatives are accurate and should be acted upon.
* False negatives are more dangerous because they fail to identify real threats, but they are not "ignored" since they do not trigger alerts.

解説：
= A change control request is a document that describes the proposed change to a system, the reason for the change, the expected impact, the approval process, the testing plan, the implementation plan, the rollback plan, and the communication plan. A change control request is a best practice for applying any patch to a production system, especially a high-priority one, as it ensures that the change is authorized, documented, tested, and communicated. A change control request also minimizes the risk of unintended consequences, such as system downtime, data loss, or security breaches. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 6, page 235. CompTIA Security+ SY0-701 Exam Objectives, Domain 4.1, page 13.

クライアント ファイルには、情報を知る必要があり、会社内で特定の役割を持つ従業員のみがアクセスできます。このセキュリティの概念を最もよく表しているのは次のどれですか。
- A. 否認防止
- B. 可用性
- C. 誠実さ
- D. 機密保持
正解：D
解説：
The scenario described, where client files are only accessible to employees who "need to know" the information, reflects the concept of confidentiality. Confidentiality ensures that sensitive information is only accessible to those who are authorized to view it, preventing unauthorized access.
* Availability ensures that data is accessible when needed but doesn't focus on restricting access.
* Integrity ensures that data remains accurate and unaltered but doesn't pertain to access control.
* Non-repudiation ensures that actions cannot be denied after they are performed, but this concept is unrelated to access control.
質問 # 139
銀行は顧客の Pll を格納する新しいサーバーを設置しました。機密データが変更されないようにするために、銀行は次のどれを使用する必要がありますか?
- A. ユーザー行動分析
- B. ネットワークアクセス制御
- C. フルディスク暗号化
- D. ファイルの整合性監視
正解：D
解説：
To ensure that sensitive data, such as Personally Identifiable Information (PII), is not modified, the bank should implement file integrity monitoring (FIM). FIM tracks changes to files and provides alerts if unauthorized modifications are detected, ensuring data integrity.
* Full disk encryption protects data at rest but does not prevent or monitor modifications.
* Network access control (NAC) manages access to the network but doesn't monitor file changes.
* User behavior analytics (UBA) detects suspicious user activities but is not focused on file integrity.
質問 # 140
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. ブルートフォース
- B. パスワードスプレー
- C. ハッシュを渡す
- D. アカウント偽造
正解：B
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 # 141
運用サーバーに影響を与えずに潜在的な攻撃者の活動を特定するために使用できるのは次のうちどれですか?
- A. ハニーポット
- B. ゼロトラスト
- C. ビデオ監視
- D. ジオフェンシング
正解：A
解説：
A honey pot is a system or a network that is designed to mimic a real production server and attract potential attackers. A honey pot can be used to identify the attacker's methods, techniques, and objectives without affecting the actual production servers. A honey pot can also divert the attacker's attention from the real targets and waste their time and resources12.
The other options are not effective ways to identify potential attacker activities without affecting production servers:
Video surveillance: This is a physical security technique that uses cameras and monitors to record and observe the activities in a certain area. Video surveillance can help to deter, detect, and investigate physical intrusions, but it does not directly identify the attacker's activities on the network or the servers3.
Zero Trust: This is a security strategy that assumes that no user, device, or network is trustworthy by default and requires strict verification and validation for every request and transaction. Zero Trust can help to improve the security posture and reduce the attack surface of an organization, but it does not directly identify the attacker's activities on the network or the servers4.
Geofencing: This is a security technique that uses geographic location as a criterion to restrict or allow access to data or resources. Geofencing can help to protect the data sovereignty and compliance of an organization, but it does not directly identify the attacker's activities on the network or the servers5.
