NEW QUESTION # 149
What.are the two elements of the risk analysis category of an IACS?
Available Choices (select all choices that are correct)
Answer: C
Explanation:
The risk analysis category of an IACS consists of two elements: business rationale and risk identification and classification1. Business rationale is the process of defining the scope, objectives, and criteria for the risk analysis, as well as the roles and responsibilities of the stakeholders involved. Risk identification and classification is the process of identifying the assets, threats, vulnerabilities, and consequences of a cyberattack on the IACS, and assigning a risk level to each scenario based on the likelihood and impact of the attack1. These elements are essential for establishing a baseline of the current risk posture of the IACS and determining the appropriate risk treatment measures to reduce the risk to an acceptable level.

NEW QUESTION # 150
What is the primary audience for Part 2-5 of the ISA/IEC 62443 Series - Policies & Procedures group of standards?
Answer: B
Explanation:
ISA/IEC 62443-2-5 provides requirements and guidance specifically for service providers (such as those delivering IACS-related managed services, maintenance, or cybersecurity services). While system integrators and asset owners use this guidance, its main audience is service providers, ensuring that their procedures align with cybersecurity best practices for IACS.

NEW QUESTION # 151
What is the purpose of ISO/IEC 15408 (Common Criteria)?
Available Choices (select all choices that are correct)
Answer: C
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 # 152
Which ISA/IEC 62443 part covers technical security requirements used by product suppliers, integration service providers, and asset owners?
Answer: A
Explanation:
ISA/IEC 62443-3-3 defines system-level security requirements applicable across roles.
Step 1: System focus
Part 3-3 specifies technical security requirements for IACS systems, independent of who implements them.
Step 2: Multi-role applicability
These requirements are used by:
* Product suppliers (design alignment)
* System integrators (implementation)
* Asset owners (operation and verification)
Step 3: Distinction from other parts
* 2-1 focuses on management systems
* 2-4 focuses on service providers
* 4-2 focuses on component-level requirements
Thus, Option C is correct.
NEW QUESTION # 153
Which steps are part of implementing countermeasures?
Available Choices (select all choices that are correct)
Answer: A
Explanation:
According to the ISA/IEC 62443-3-2 standard, implementing countermeasures is one of the steps in the security risk assessment for system design. The standard defines a comprehensive set of engineering measures to guide organizations through the process of assessing the risk of a particular industrial automation and control system (IACS) and identifying and applying security countermeasures to reduce that risk to tolerable levels. The standard recommends the following steps for implementing countermeasures:
* Establish the risk tolerance: This step involves determining the acceptable level of risk for the organization and the system under consideration, based on the business objectives, legal and regulatory requirements, and stakeholder expectations. The risk tolerance can be expressed as a target security level (SL-T) for each zone or conduit in the system.
* Select common countermeasures: This step involves selecting the appropriate security countermeasures for each zone or conduit, based on the SL-T and the existing security level (SL-A) of the system. The standard provides a list of common countermeasures for each security level, covering the domains of physical security, network security, system security, and application security. The selected countermeasures should be documented and justified in the security risk assessment report. References:
