NEW QUESTION # 63
Which is the PRIMARY reason why Modbus over Ethernet is easy to manaqe in a firewall?
Available Choices (select all choices that are correct)
Answer: B
Explanation:
According to the ISA/IEC 62443-2-4 standard, a training and security awareness program should include all personnel who have access to the industrial automation and control system (IACS) or who are involved in its operation, maintenance, or management. This includes vendors and suppliers, employees, temporary staff, contractors, and visitors. The purpose of the program is to ensure that all personnel are aware of the security risks and policies related to the IACS, and that they have the necessary skills and knowledge to perform their roles in a secure manner. The program should also cover the roles and responsibilities of different personnel, the reportingprocedures for security incidents, and the best practices for security hygiene. References:

NEW QUESTION # 64
Why is it important to document the results of the initial/high-level risk assessment?
Answer: D
Explanation:
Documenting the results of the initial or high-level risk assessment is crucial to establish a baseline for cybersecurity posture and risk. This baseline serves as a reference for tracking progress, justifying future investments, measuring improvements, and supporting subsequent detailed risk assessments. It also aids in communication with stakeholders and auditors.
Reference: ISA/IEC 62443-2-1:2009, Section 5.2.3 ("Documenting results and baseline"); ISA/IEC 62443-3-
2:2020, Section 4.3.4.
NEW QUESTION # 65
Which of the following is an example of separation of duties as a part of system development and
maintenance?

Answer: D
NEW QUESTION # 66
Which is an important difference between IT systems and IACS?
Answer: A
Explanation:
A key distinguishing factor between IT (Information Technology) and IACS (Industrial Automation and Control Systems) environments is the **requirement for cybersecurity to consider safety in IACS systems.
From ISA/IEC 62443-1-1, Clause 4.3:
"In contrast to traditional IT environments, where the primary concern is confidentiality, the primary concerns in IACS environments are often availability, integrity, and most critically - safety." Any cybersecurity failure in IACS environments can result in physical consequences, such as equipment damage, environmental harm, or loss of human life - making safety a critical consideration.
Incorrect Options:
A). Integrity is important, but availability and safety are usually higher priorities.
B). IT prioritizes confidentiality, not availability.
D). Routers are indeed used in IACS networks, often hardened or industrial-grade.

NEW QUESTION # 67
A national standards body wants to represent its country's interests at an international level and adopt global standards locally. What role does this organization fulfill?
Answer: C
Explanation:
ISA/IEC 62443 is developed within the international standards system, where national participation is coordinated through National Standardization Bodies (NSBs). These organizations represent their country's interests in international standards committees and manage the adoption of international standards at the national level.
Step 1: Role of a National Standardization Body
An NSB acts as the official representative of a country within international standards organizations such as IEC and ISO. It coordinates national input, votes on standards, and nominates experts to technical committees.
Step 2: Adoption of international standards
NSBs are responsible for adopting international standards as national standards, often with minimal or no modification. This enables consistent global alignment while supporting local implementation.
Step 3: Why other options are incorrect
* Global SDOs develop standards internationally but do not represent individual countries.
* Regulatory agencies enforce laws, not standards.
* Industry consortia represent private-sector interests, not national positions.
Thus, the correct role is National Standardization Body.
