問題 #89
Safety management staff are stakeholders of what security program development?
Available Choices (select all choices that are correct)
答案：C
問題 #90
Which is the PRIMARY objective when defining a security zone?
Available Choices (select all choices that are correct)
答案：C
解題說明：
According to the ISA/IEC 62443-3-2 standard, a security zone is a grouping of systems and components based on their functional, logical, and physical relationship that share common security requirements. The primary objective of defining a security zone is to apply a consistent level of protection to the assets within the zone, based on their criticality and risk assessment. A security zone may contain assets from different vendors, different levels in the Purdue model, or different physical locations, as long as they have the same security requirements. A security zone may also be subdivided into subzones, if there are different security requirements within the zone. A conduit is a logical or physical grouping of communication channels connecting two or more zones that share common security requirements.

問題 #91
A company needs to create a standardized interface for exchanging real-time plant data between heterogeneous control devices while maintaining a structured organization of data elements such as folders, classes, and methods. Which feature of OPC supports this requirement?
答案：C
解題說明：
OPC Unified Architecture (OPC UA) introduces a browsable namespace that supports hierarchical organization of data including folders, classes, methods, and object types. This is critical for structured access to real-time and historical data across heterogeneous control systems.
"OPC UA provides a flexible, secure, and platform-independent mechanism for exchanging information. Its browsable namespace allows structured navigation of nodes, types, and attributes in a hierarchical format."
- OPC UA Specification, Part 3 - Address Space Model
This is a key improvement over OPC Classic, which was tightly coupled to DCOM and lacked standardized structures across systems.

問題 #92
How many element qroups are in the "Addressinq Risk" CSMS cateqorv?
Available Choices (select all choices that are correct)
答案：C
解題說明：
The "Addressing Risk" CSMS category consists of three element groups: Security Policy, Organization and Awareness; Selected Security Countermeasures; and Implementation of Security Program1. These element groups cover the aspects of defining the security objectives, roles and responsibilities, policies and procedures, awareness and training, security countermeasures selection and implementation, and security program execution and maintenance1. The "Addressing Risk" CSMS category aims to reduce the security risk to an acceptable level by applying appropriate security measures to the system under consideration (SuC)

問題 #93
Which of the following PRIMARILY determines access privileges for user accounts?
Available Choices (select all choices that are correct)
答案：B
解題說明：
Authorization security policy is the primary factor that determines access privileges for user accounts. Authorization security policy is the function of specifying access rights or privileges to resources, which is related to general information security and computer security, and to accesscontrol in particular1.
Authorization security policy defines who can access what resources, under what conditions, and for what purposes. Authorization security policy should be aligned with the business objectives and security requirements of the organization, and should be enforced by appropriate mechanisms and controls. Authorization security policy should also be reviewed and updated regularly to reflect changes in the environment, threats, and risks2. Authorization security policy is an essential part of the ISA/IEC 62443 standard, which provides a framework for securing industrial automation and control systems (IACS). The standard defines four security levels (SL) that represent the degree of protection against threats, and specifies the security capabilities that should be implemented for each SL. The standard also provides guidance on how to conduct a security risk assessment, how to define security zones and conduits, and how to apply security policies and procedures to the IACS environment34 .
