質問 # 53
Which of the following ISA-99 (IEC 62443) Reference Model levels is named correctly?
正解：D
解説：
According to ISA/IEC 62443-1-1:2007 (Terminology, Concepts, and Models), the functional levels of the Industrial Automation and Control System (IACS) are derived from the Purdue Enterprise Reference Architecture (PERA). These levels are defined as follows:
Level
Function
Description
Level 0
Process
The actual physical process, including sensors and actuators.
Level 1
Basic Control
Devices responsible for direct control, such as PLCs and RTUs.
Level 2
Area Supervisory Control
Supervisory systems such as HMIs and SCADA, responsible for monitoring/control.
Level 3
Site Manufacturing Operations Management
Operations management systems such as MES, production scheduling, and workflow.
Level 4
Business Planning and Logistics
Enterprise-level systems such as ERP, supply chain, and logistics.
Analysis of Each Option:
Option A: Level 1: Supervisory Control
Incorrect. Level 1 is defined as Basic Control, not Supervisory Control. Supervisory functions appear at Level
2.
Option B: Level 2: Quality Control
Incorrect. Level 2 is defined as Area Supervisory Control, not Quality Control.
Option C: Level 3: Operations Management
Correct. Level 3 is specifically identified as Operations Management, which includes manufacturing execution and scheduling functions.
Option D: Level 4: Process
Incorrect. Level 4 corresponds to Business Planning and Logistics. The Process is represented at Level 0.

質問 # 54
Which of the following is a trend that has caused a significant percentage of security vulnerabilities?
Available Choices (select all choices that are correct)
正解：B
解説：
One of the trends that has increased the security risks for industrial automation and control systems (IACS) is the integration of these systems with business and enterprise systems, such asenterprise resource planning (ERP), manufacturing execution systems (MES), and supervisory control and data acquisition (SCADA). This integration exposes the IACS to the same threats and vulnerabilities that affect the business and enterprise systems, such as malware, denial-of-service attacks, unauthorized access, and data theft. Moreover, the integration also creates new attack vectors and pathways for adversaries to compromise the IACS, such as through remote access, wireless networks, or third-party devices. Therefore, the integration of IACS with business and enterprise systems is a trend that has caused a significant percentage of security vulnerabilities.

質問 # 55
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 # 57
Electronic security, as defined in ANSI/ISA-99.00.01:2007. includes which of the following?
Available Choices (select all choices that are correct)
正解：A、B
解説：
In ANSI/ISA-99.00.01:2007, which is part of the ISA/IEC 62443 standards, electronic security encompasses both the technical and human aspects of cybersecurity within industrial automated and control systems (IACS). Option B correctly highlights components such as computers, networks, operating systems, applications, and other programmable configurable components which are intrinsic to the system's electronic security framework. Option C is also correct as it includes the personnel, policies, and procedures which play a crucial role in securing these systems. This emphasizes that security is not only about the technological solutions but also about managing human elements and organizational processes effectively.
ISA/IEC 62443 Cybersecurity Fundamentals References:
* ISA/IEC 62443 standards focus on the holistic nature of security which is clearly supported by including both the technological (Option B) and human elements (Option C) in the definition of electronic security.
