質問 # 159
Which of the following staff is NOT mentioned as a stakeholder in the CSMS Program?
正解：C
解説：
Within the context of the Cyber Security Management System (CSMS) as defined in ISA/IEC 62443-2-1, the primary stakeholders include operations staff (responsible for system operations), IT security staff (for information technology and cybersecurity controls), and physical security staff (for site access and physical barriers). Marketing staff are not typically listed as stakeholders in the design, implementation, or maintenance of the CSMS, since their role does not directly influence the security posture of industrial control systems. This is outlined in the roles and responsibilities sections of the standard.
Reference: ISA/IEC 62443-2-1:2009, Section 4.3.2 ("CSMS Program Stakeholders" and Table 1 - Typical Stakeholders).

質問 # 162
Which is the BEST practice when establishing security zones?
Available Choices (select all choices that are correct)
正解：D
解説：
Security zones are logical groupings of assets that share common security requirements based on factors such as criticality, consequence, vulnerability, and threat. Security zones are used to apply the principle of defense in depth, which means creating multiple layers of protection to prevent or mitigate cyberattacks. By creating security zones, asset owners can isolate the most critical or sensitive assets from the less critical or sensitive ones, and apply different levels of security controls to each zone according to the risk assessment. Security zones are not necessarily aligned with physical network segments, as assets within the same network may have different security requirements. For example, a network segment may contain both a safety instrumented system (SIS) and a human-machine interface (HMI), but the SIS has a higher security requirement than the HMI. Therefore, the SIS and the HMI should be in different security zones, even if they are in the same network segment. Similarly, assets within the same logical communication network may not have the same security requirements, and therefore should not be in the same security zone. For example, a logical communication network may span across multiple physical locations, such as a plant and a corporate office, but the assets in the plant may have higher security requirements than the assets in the office. Therefore, the assets in the plant and the office should be in different security zones, even if they are in the same logical communication network. Finally, all components in a large or complex system should not be in the same security zone, as this would create a single point of failure and expose the entire system to potential cyberattacks. Instead, the components should be divided into smaller and simpler security zones, based on their security requirements, and the communication between the zones should be controlled by conduits.
Conduits are logical or physical connections between security zones that allow data flow and access control.
Conduits should be designed to minimize the attack surface and the potential impact of cyberattacks, by applying security controls such as firewalls, encryption, authentication, and authorization. References:
