質問 # 43
Which of the following ISA-99 (IEC 62443) Reference Model levels is named correctly?
Available Choices (select all choices that are correct)
正解：A
解説：
The ISA-99/IEC 62443 standards for industrial automation and control systems security categorize network and system components into different levels based on their operational context. The correct name from the provided options for one of these levels is Level 3: Operations Management. This level typically encompasses systems that manage production control systems, including batch management, production scheduling, and overall factory operations. The other levels listed, such as Supervisory Control and Process, refer to different aspects of the system but are not named correctly in the options provided. Level 1 is correctly referred to as
"Basic Control," and Level 4 should be "Business Logistics" instead of "Process."
質問 # 44
As related to IACS Maintenance Service Providers, when do maintenance activities generally start?
正解：A
解説：
In the context of ISA/IEC 62443, maintenance activities by IACS Maintenance Service Providers generally begin after the solution (such as a control system or automation project) is handed over to the asset owner.
This marks the transition from project (installation and commissioning) to operational maintenance, which includes patching, updating, and other support activities as part of the system lifecycle.
Reference: ISA/IEC 62443-2-4:2015, Section 4.3.3 ("Service provider maintenance activities after handover").
質問 # 45
Which is the PRIMARY responsibility of the network layer of the Open Systems Interconnection (OSI) model?
Available Choices (select all choices that are correct)
正解：A
解説：
The primary responsibility of the network layer of the Open Systems Interconnection (OSI) model is to forward packets, including routing through intermediate routers. The network layer is the third layer from the bottom of the OSI model, and it is responsible for maintaining the quality of the data and passing and transmitting it from its source to its destination. The network layer also assigns logical addresses to devices, such as IP addresses, and uses various routing algorithms to determine the best path for the packets to travel.
The network layer operates on packets, which are units of data that contain the source and destination addresses, as well as the payload. The network layer forwards packets from one node to another, using routers to switch packets between different networks. The network layer also handles host-to-host delivery, which means that it ensures that the packets reach the correct destination host.
The other choices are not correct because:
* B. Gives transparent transfer of data between end users. This is the responsibility of the transport layer, which is the fourth layer from the bottom of the OSI model. The transport layer provides reliable and error-free data transfer between end users, using protocols such as TCP and UDP. The transport layer operates on segments, which are units of data that contain the source and destination port numbers, as well as the payload. The transport layer also handles flow control, congestion control, and multiplexing.
* C. Provides the rules for framing, converting electrical signals to data. This is the responsibility of the data link layer, which is the second layer from the bottom of the OSI model. The data link layer provides the means for transferring data between adjacent nodes on a network, using protocols such as Ethernet and WiFi. The data link layer operates on frames, which are units of data that contain the source and destination MAC addresses, as well as the payload. The data link layer also handles error detection, error correction, and media access control.
* D. Handles the physics of getting a message from one device to another. This is the responsibility of the physical layer, which is the lowest layer of the OSI model. The physical layer provides the means for transmitting bits over a physical medium, such as copper wire, fiber optic cable, or radio waves. The physical layer operates on bits, which are the smallest units of data that can be either 0 or 1. The physical layer also handles modulation, demodulation, encoding, decoding, and synchronization.

質問 # 46
What is the definition of "defense in depth" when referring to
Available Choices (select all choices that are correct)
正解：A
解説：
Defense in depth is a concept of cybersecurity that involves applying multiple layers of protection to a system or network, so that if one layer fails, another layer can prevent or mitigate an attack. Defense in depth is based on the principle that no single security measure is perfect or sufficient, and that multiple countermeasures can provide redundancy and diversity of defense. Defense in depth can also increase the cost and complexity for an attacker, as they have to overcome more obstacles and exploit more vulnerabilities to achieve their goals.
Defense in depth is one of the key concepts of the ISA/IEC 62443 series of standards, which provide guidance and best practices for securing industrial automation and control systems (IACS). The standards recommend applying defense in depth strategies at different levels of an IACS, such as the network, the system, the component, and the policy and procedure level. The standards also define different zones and conduits within an IACS, which are logical or physical groupings of assets that share common security requirements and risk levels. By applying defense in depth strategies to each zone and conduit, the security of the entire IACS can be improved. References:

What does the abbreviation CSMS round in ISA 62443-2-1 represent?
Available Choices (select all choices that are correct)
正解：A
解説：
The abbreviation CSMS stands for Cyber Security Management System in ISA 62443-2-1. This standard defines the elements necessary to establish a CSMS for industrial automation and control systems (IACS) and provides guidance on how to develop those elements123. A CSMS is a collection of policies, procedures, practices, and personnel that are responsible for ensuring the security of IACS throughout their lifecycle24.
