ISA/IEC 62443 Cybersecurity Fundamentals Specialist Sample Questions (Q182-Q187):NEW QUESTION # 182
In what step of the development process of the CSMS is "Establish purpose, organizational support, resources, and scope" taken care of?
  • A. Initiate the CSMS program.
  • B. Conduct an initial/high-level risk assessment.
  • C. Create reference architecture.
  • D. Establish policy, organization, and awareness.
Answer: A
Explanation:
The first step in the Cyber Security Management System (CSMS) development process is to "Initiate the CSMS program," which involves establishing its purpose, obtaining organizational support, allocating resources, and defining the program's scope. These foundational activities are required to ensure that the program is properly structured and supported before detailed risk assessments or architecture planning are performed.
Reference: ISA/IEC 62443-2-1:2009, Section 5.1 ("Initiate the CSMS program").

NEW QUESTION # 183
Why is it important for the asset owner to incorporate the IACS into its organization and security program during the Operation and Maintenance phase?
  • A. To embed the IACS within organizational processes and people
  • B. To guarantee that the maintenance service provider has full control over the system
  • C. To allow the product supplier to update the system remotely without oversight
  • D. To ensure that the system can be decommissioned immediately if needed
Answer: A
Explanation:
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.

NEW QUESTION # 184
Which of the following is an industry sector-specific standard?
Available Choices (select all choices that are correct)
  • A. ISA-62443 (EC 62443)
  • B. API 1164
  • C. D. ISO 27001
  • D. NIST SP800-82
Answer: B
Explanation:
API 1164 is an industry sector-specific standard that provides guidance on the cybersecurity of pipeline supervisory control and data acquisition (SCADA) systems. API stands for American Petroleum Institute, which is the largest U.S. trade association for the oil and natural gas industry. API 1164 was first published in
2004 and revised in 2009 and 2021. The latest version of the standard aligns with the ISA/IEC 62443 series of standards and incorporates the concepts of security levels, zones, and conduits. API 1164 covers the security lifecycle of pipeline SCADA systems, from risk assessment and policy development to implementation and maintenance. The standard also defines roles and responsibilities, security requirements, security controls, and security assessment methods for pipeline SCADA systems.

NEW QUESTION # 185
Which service does an Intrusion Detection System (IDS) provide?
  • A. It blocks malicious activity in networks and computer systems.
  • B. It is the lock on the door for networks and computer systems.
  • C. It detects attempts to break into or misuse a computer system.
  • D. It is effective against all vulnerabilities in networks and computer systems.
Answer: C
Explanation:
An Intrusion Detection System (IDS) is a passive monitoring tool that detects unauthorized or malicious activity in networked systems. It does not block traffic (like an IPS), but rather alerts administrators to potential breaches.
"An IDS monitors network or system activities for malicious actions or policy violations and produces alerts or logs for analysis."
- ISA/IEC 62443-3-3:2013, SR 3.2 - Detection of Security Events
It's a core component of security monitoring and response - often paired with an Incident Response Plan (IRP) as defined in ISA/IEC 62443-2-1.
Clarification of Options:
Option A is metaphorical and not technically accurate.
Option B is false; IDS does not protect against all vulnerabilities.
Option C is incorrect; IDS does not block, only detects.
Option D is correct - it detects unauthorized access or misuse.

NEW QUESTION # 186
What does the System under Consideration (SuC) include in the context of ISA/IEC 62443 risk assessment?
  • A. External vendor devices and business zone assets only
  • B. Only business zone assets
  • C. A defined collection of IACS and related assets
  • D. Only physical assets within an existing plant
Answer: C
Explanation:
ISA/IEC 62443-3-2 introduces the concept of the System under Consideration (SuC) as the scope boundary for risk assessment.
Step 1: Purpose of the SuC
The SuC defines exactly what is being analyzed for cybersecurity risk.
Step 2: Inclusive scope
It includes a defined collection of IACS components, systems, zones, conduits, and supporting assets that contribute to the system's function.
Step 3: Why definition matters
A clearly defined SuC ensures accurate threat modeling, impact analysis, and Security Level determination.
Step 4: Why other options are incorrect
Limiting the SuC to business assets or physical devices ignores logical, networked, and functional dependencies.
Therefore, the correct answer is a defined collection of IACS and related assets.
