ISA/IEC 62443 Cybersecurity Fundamentals Specialist 認定 ISA-IEC-62443 試験問題 (Q87-Q92):質問 # 87
Why is segmentation from non-IACS zones important in Network & Communication Security (SP Element
3)?
  • A. To prevent attacks originating outside the IACS
  • B. To classify data according to sensitivity levels
  • C. To manage user identity persistence effectively
  • D. To ensure backup verification processes run smoothly
正解：A
解説：
SP Element 3 in ISA/IEC 62443-2-1 focuses on Network and Communication Security, with segmentation as a foundational control.
Step 1: Threat origin reality
Many cyberattacks targeting IACS originate from enterprise IT networks, remote access paths, or external connections. Without segmentation, these threats can propagate directly into control systems.
Step 2: Zones and conduits concept
ISA/IEC 62443 requires logical and physical separation between IACS zones and non-IACS zones, with controlled conduits enforcing security policies.
Step 3: Attack surface reduction
Segmentation limits exposure by ensuring that only explicitly authorized communications can cross zone boundaries.
Step 4: Why other options are incorrect
Data classification, identity persistence, and backup verification are handled by other SP Elements and foundational requirements.
Thus, segmentation is critical to prevent attacks originating outside the IACS, making Option B correct.

質問 # 88
Which is the PRIMARY reason why Modbus over Ethernet is easy to manaqe in a firewall?
Available Choices (select all choices that are correct)
  • A. Modbus is a proprietary protocol that is widely supported by vendors.
  • B. Modbus uses explicit source and destination IP addresses and a sinqle known TCP port.
  • C. Modbus has no known security vulnerabilities, so firewall rules are simple to implement.
  • D. Modbus uses a single master to communicate with multiple slaves usinq simple commands.
正解：B
解説：
According to the ISA/IEC 62443-2-4 standard, a training and security awareness program should include all personnel who have access to the industrial automation and control system (IACS) or who are involved in its operation, maintenance, or management. This includes vendors and suppliers, employees, temporary staff, contractors, and visitors. The purpose of the program is to ensure that all personnel are aware of the security risks and policies related to the IACS, and that they have the necessary skills and knowledge to perform their roles in a secure manner. The program should also cover the roles and responsibilities of different personnel, the reporting procedures for security incidents, and the best practices for security hygiene. References:

質問 # 89
Which U.S. Department is responsible for the Chemical Facility Anti-Terrorism Standards (CFATS)?
  • A. Nuclear Regulatory Commission
  • B. Department of Homeland Security
  • C. Department of Energy
  • D. Transportation Security Administration
正解：B
解説：
The Chemical Facility Anti-Terrorism Standards (CFATS) are managed and enforced by the U.S. Department of Homeland Security (DHS), specifically through the Cybersecurity and Infrastructure Security Agency (CISA).
"CFATS is a DHS regulatory program focused on security at high-risk chemical facilities to prevent terrorist exploitation of chemicals of interest."
- Department of Homeland Security, CFATS Program Overview
These standards require facilities to perform vulnerability assessments and implement site security plans, aligning with principles from frameworks like ISA/IEC 62443.

質問 # 90
Which of the following is the underlying protocol for Ethernet/IP?
Available Choices (select all choices that are correct)
  • A. Highway Addressable Remote Transducer (HART)
  • B. Object Linking and Embedding (OLE) for Process Control
  • C. Building Automation and Control Network (BACnet)
  • D. Common Industrial Protocol
正解：D
解説：
Ethernet/IP is an industrial network protocol that adapts the Common Industrial Protocol (CIP) to standard Ethernet. CIP is an object-oriented protocol that provides a unified communication architecture for various industrial automation applications, such as control, safety, security, energy, synchronization and motion, information and network management. CIP defines a set of messages and services for interacting with devices and data on the network, as well as a set of device profiles for consistent implementation of automation functions across different products. Ethernet/IP uses the transport and control protocols of standard Ethernet, such as TCP/IP and IEEE 802.3, to define the features and functions for its lower layers. Ethernet/IP also uses UDP to transport I/O messages and supports various network topologies, such as star, linear, ring and wireless. Ethernet/IP is one of the leading industrial protocols in the United States and is widely used in a range of industries, such as factory, hybrid and process. Ethernet/IP is managed by ODVA, Inc., a global trade and standards development organization. References:

質問 # 91
After receiving an approved patch from the JACS vendor, what is BEST practice for the asset owner to follow?
  • A. If a medium priority, schedule the installation within three months after receipt.
  • B. If a low priority, there is no need to apply the patch.
  • C. If no problems are experienced with the current IACS, it is not necessary to apply the patch.
  • D. If a high priority, apply the patch at the first unscheduled outage.
正解：D
解説：
According to the ISA/IEC 62443 Cybersecurity Fundamentals Specialist resources, patches are software updates that fix bugs, vulnerabilities, or improve performance of a system. Patches are classified into three categories based on their urgency and impact: low, medium, and high. Low priority patches are those that have minimal or no impact on the system functionality or security, and can be applied at the next scheduled maintenance. Medium priority patches are those that have moderate impact on the system functionality or security, and should be applied within a reasonable time frame, such as three months. High priority patches are those that have significant or critical impact on the system functionality or security, and should be applied as soon as possible, preferably at the first unscheduled outage. Applying patches in a timely manner is a best practice for maintaining the security and reliability of an industrial automation and control system (IACS). References:
