NEW QUESTION # 156
What is the primary audience for Part 2-5 of the ISA/IEC 62443 Series - Policies & Procedures group of standards?
Answer: D
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.
Reference: ISA/IEC 62443-2-5:2019, Scope and Introduction.
NEW QUESTION # 157
Which ISA/IEC 62443 part covers technical security requirements used by product suppliers, integration service providers, and asset owners?
Answer: A
Explanation:
ISA/IEC 62443-4-2 specifies technical security requirements (TSRs) for individual IACS components such as:
Embedded devices
Software applications
Network components
Host devices
These TSRs are relevant for product suppliers who design the components, integration service providers who implement them, and asset owners who operate them.
"This standard specifies the technical security requirements for components used in an IACS, and is applicable to product suppliers, system integrators, and asset owners responsible for security implementation."
- ISA/IEC 62443-4-2:2018, Clause 1 - Scope
The 62443-3-3 standard complements it by specifying system-level requirements, while 62443-2-4 focuses on service providers and 62443-2-1 on security program management.

ISA/IEC 62443-4-2:2018 - Clause 1

Available Choices (select all choices that are correct)
Answer: D
NEW QUESTION # 159
Which of the following PRIMARILY determines access privileges for user accounts?
Available Choices (select all choices that are correct)
Answer: A
Explanation:
Authorization security policy is the primary factor that determines access privileges for user accounts. Authorization security policy is the function of specifying access rights or privileges to resources, which is related to general information security and computer security, and to access control in particular1.
Authorization security policy defines who can access what resources, under what conditions, and for what purposes. Authorization security policy should be aligned with the business objectives and security requirements of the organization, and should be enforced by appropriate mechanisms and controls. Authorization security policy should also be reviewed and updated regularly to reflect changes in the environment, threats, and risks2. Authorization security policy is an essential part of the ISA/IEC 62443 standard, which provides a framework for securing industrial automation and control systems (IACS). The standard defines four security levels (SL) that represent the degree of protection against threats, and specifies the security capabilities that should be implemented for each SL. The standard also provides guidance on how to conduct a security risk assessment, how to define security zones and conduits, and how to apply security policies and procedures to the IACS environment34 .

NEW QUESTION # 160
Whose responsibility is it to determine the level of risk an organization is willing to tolerate?
Available Choices (select all choices that are correct)
Answer: A
Explanation:
According to the ISA/IEC 62443 standards, the level of risk an organization is willing to tolerate is determined by the management, as they are responsible for defining the business and risk objectives, as well as the security policies and procedures for the organization. The management also has the authority to allocate the necessary resources and assign the roles and responsibilities for implementing and maintaining the security program. The legal, operations, and safety departments may provide input and feedback to the management, but they do not have the final say in determining the risk tolerance level. References: ISA/IEC
62443-2-1:2010 - Establishing an industrial automation and control systems security program, section 4.2.1.
