NEW QUESTION # 163
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: A
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.

NEW QUESTION # 165
What is the purpose of ISO/IEC 15408 (Common Criteria)?
Available Choices (select all choices that are correct)
Answer: B
Explanation:
ISO/IEC 15408, also known as the Common Criteria for Information Technology Security Evaluation, is an international standard that provides a framework for evaluating the security of IT products and systems. The purpose of the standard is to define a common set of requirements for the security functions and assurance measures of IT products and systems, and to establish a common methodology for conducting security evaluations. The standard allows users to specify their security needs and expectations in a Security Target (ST), which may be based on one or more Protection Profiles (PPs) that define security requirements for a class of products or systems. Vendors can then implement or claim compliance with the ST or PPs, and have their products or systems evaluated by independent testing laboratories against the security criteria defined in the standard. The standard also defines a scale of Evaluation Assurance Levels (EALs) that indicate the degree of confidence in the security of the evaluated product or system. The standard is intended to facilitate the development, procurement, and use of secure IT products and systems, and to promote the recognition and acceptance of evaluation results across different countries and regions.

NEW QUESTION # 166
During the operation of an IACS, who is responsible for executing the Security Protection Scheme (SPS) process measures and responding to emerging risks?
Answer: A
Explanation:
The asset owner holds ultimate responsibility for implementing and maintaining security measures, including the Security Protection Scheme (SPS) during the operational phase of the lifecycle. According to ISA/IEC
62443-2-1 and ISA/IEC 62443-1-1, the asset owner is tasked with ensuring that the necessary security policies, procedures, and controls are effectively executed and maintained.
"The asset owner shall define and maintain the operational security policies and procedures, ensuring the execution of the protection scheme and risk mitigation actions."
- ISA/IEC 62443-2-1:2010, Section 4.3
Furthermore, ISA/IEC 62443-1-1 clearly defines the roles and responsibilities of the asset owner in terms of operational security enforcement and ongoing risk response.
