質問 # 13
What type of malware disrupted an emergency shutdown capability in safety systems?
正解：D
解説：
The Triton (also known as Trisis) malware specifically targeted and compromised Safety Instrumented Systems (SIS), disabling the emergency shutdown capabilities at a petrochemical plant. This attack demonstrated that safety systems, once considered isolated and secure, are vulnerable to sophisticated, targeted cyberattacks. Neither Zeus, Stuxnet, nor WannaCry had this specific impact on emergency shutdown safety systems.

質問 # 14
A company discovers malware on a portable USB device used within their IACS environment. According to the document, which SP Element and controls would be MOST relevant to address this issue?
正解：C
解説：
ISA/IEC 62443-2-1 defines SP Element 4 as covering component hardening, malware protection, and the secure use of portable and mobile media. Malware introduced through USB devices is a well-known attack vector in IACS environments, and the standard addresses this risk explicitly through preventive controls rather than only reactive measures.
Step 1: Nature of the threat
Portable media such as USB drives bypass network-based defenses and can introduce malware directly into critical control systems. ISA/IEC 62443 recognizes this as a high-risk vector, especially in air-gapped or semi- isolated systems.
Step 2: SP Element 4 scope
SP Element 4 requires asset owners to implement technical controls such as:
* Restrictions on the use of portable media
* Use of dedicated, controlled media
* Malware scanning before use
* Hardening of endpoints to prevent unauthorized execution
Step 3: Why other SP Elements are secondary
* SP Element 1 focuses on anomaly detection, not prevention.
* SP Element 2 concerns inventory accuracy.
* SP Element 7 applies after an incident has occurred.
Step 4: Preventive emphasis
The standard prioritizes prevention of malware introduction through controlled media usage, making SP Element 4 the most relevant.
質問 # 15
Which of the following provides the overall conceptual basis in the design of an appropriate security program?
正解：D
解説：
The reference model provides the overall conceptual basis for designing an appropriate security program. The ISA/IEC 62443-1-1 standard introduces the reference model to explain the structure, concepts, and relationships within an industrial automation and control system (IACS). It establishes the foundation for applying zones and conduits and for understanding security levels and how assets interact. This model is the cornerstone for implementing other architectural and technical security controls.
Reference: ISA/IEC 62443-1-1:2007, Section 4.2, "Reference Model"; also see Figure 1 in 62443-1-1.
質問 # 16
Safety management staff are stakeholders of what security program development?
Available Choices (select all choices that are correct)
正解：D
解説：
Safety management staff are stakeholders of the CSMS, which stands for Cybersecurity Management System. The CSMS is a framework for managing the cybersecurity of industrial automation and control systems (IACS) based on the ISA/IEC 62443-2-1 standard1. The CSMS defines the objectives, policies, metrics, and governance for the overall ICS security program2. The CSMS also includes the processes for risk assessment, security design, implementation, monitoring, and improvement3. Safety management staff are involved in the CSMS development and implementation, as they are responsible for ensuring the safety of the IACS and the people, environment, and assets that depend on it. Safety management staff need to coordinate with the security management staff to align the safety and security requirements, identify and mitigate the safety risks arising from cyber threats, and monitor and respond to safety incidents caused by cyberattacks.

質問 # 17
Which model describes relationships between assets within an industrial automation and control system?
正解：D
解説：
The asset model is used in ISA/IEC 62443 to represent and describe the relationships and dependencies between different assets in an IACS environment. This model helps organizations identify and document assets, their interconnections, and their significance for operational and cybersecurity purposes. The zone model builds upon the asset model for segmentation, but the asset model itself establishes the foundational relationships.
