NEW QUESTION # 220
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 # 221
Why is it important for the asset owner to incorporate the IACS into its organization and security program during the Operation and Maintenance phase?
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 # 222
Which of the following PRIMARILY determines access privileges for user accounts?
Available Choices (select all choices that are correct)
Answer: D
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 # 224
If an asset owner wants to improve their organization's ability to respond during a cyberattack, which of the following activities would be MOST appropriate to implement?
Answer: D
Explanation:
Tabletop exercises simulate cybersecurity incidents in a non-disruptive setting, helping teams test and improve their incident response plans and communication protocols.
"Tabletop exercises allow personnel to rehearse roles, responsibilities, and actions in a simulated event scenario. This enhances coordination, preparedness, and decision-making during actual incidents."
- ISA/IEC 62443-2-1:2010, Clause 4.3.3.3 - Incident Response Preparedness They are essential for verifying that the incident handling process (SP Element 7) is both understood and effective.
