질문 # 129
A company is developing an automation solution and wants to align its cybersecurity efforts with ISA/IEC
62443 standards. Which lifecycle phases should be integrated into their project plan to cover both security and automation solution security comprehensively?
정답：C
설명：
ISA/IEC 62443 outlines a comprehensive security lifecycle that spans all phases of an automation system's development and deployment - from concept through decommissioning. This includes:
Specification
Design
Implementation
Integration and commissioning
Operation and maintenance
Decommissioning
"The IACS cybersecurity lifecycle includes all phases - from concept through retirement - to ensure security is addressed continuously and consistently."
- ISA/IEC 62443-1-1:2007, Clause 5 - Lifecycle Model
- ISA/IEC 62443-4-1:2018 - Secure Development Lifecycle (SDL)
Security must be integrated early (during design/specification) and maintained throughout the system's life.

질문 # 130
Why is OPC Classic considered firewall unfriendly?
정답：C
설명：
OPC Classic uses Microsoft's DCOM (Distributed Component Object Model) for communication, which dynamically opens multiple ports, making it extremely difficult to manage with firewalls.
"OPC Classic is firewall-unfriendly because DCOM requires dynamic port negotiation, making it difficult to define consistent firewall rules."
- ISA/IEC 62443-3-3:2013, Annex A - Communication Protocols and Security Concerns This lack of port predictability presents a significant security and operational risk, which led to the development of OPC UA, which uses fixed ports and supports encryption.

질문 # 131
Why is it important for the asset owner to incorporate the IACS into its organization and security program during the Operation and Maintenance phase?
정답：A
설명：
During the Operation and Maintenance phase, the asset owner is responsible for ensuring that the IACS is integrated into their broader security program, including processes, training, and monitoring.
"The asset owner shall ensure that the IACS is incorporated into their operational and security governance programs, including process ownership, personnel responsibilities, and continuous security monitoring."
- ISA/IEC 62443-2-1:2010, Clause 4.3.2 - Organizational Security Measures This ensures that cybersecurity becomes a continuous organizational function, not a one-time setup or third- party responsibility.

질문 # 132
Which is a common pitfall when initiating a CSMS program?
Available Choices (select all choices that are correct)
정답：C
설명：
"A common pitfall is to attempt to initiate a CSMS program without at least a high-level rationale that relates cyber security to the specific organization and its mission." A CSMS program is a Cybersecurity Management System program that follows the IEC 62443 standards for securing industrial control systems (ICS)1. A common pitfall when initiating a CSMS program is D.
Immediate jump into detailed risk assessment. This is because a detailed risk assessment requires a clear definition of the system under consideration (SuC), the allocation of IACS assets to zones and conduits, and the identification of threats, vulnerabilities, and consequences for each zone and conduit2. These steps are part of the assess phase of the CSMS program, which is the first phase of the security program development process2. However, before starting the assess phase, it is important to have the management team's support to ensure the CSMS program will have sufficient financial and organizational resources to implement necessary actions2. Therefore, jumping into detailed risk assessment without having the management buy-in is a common mistake that can jeopardize the success of the CSMS program.
질문 # 133
If an asset owner wants to demonstrate compliance with ISA/IEC 62443-2-1 requirements during an external audit, which type of evidence would be MOST appropriate?
정답：B
설명：
To demonstrate compliance with ISA/IEC 62443-2-1, the most effective evidence is formal documentation that shows the actual use, configuration, and operation of required cybersecurity policies and controls.
"The asset owner shall document procedures, configuration settings, and evidence of operational security controls to support compliance assessments and audits."
- ISA/IEC 62443-2-1:2010, Clause 4.3.1 - Documented Security Program
Auditors require verifiable, written proof - not informal reports or promotional material.
