NEW QUESTION # 197
Which of the following is a trend that has caused a significant percentage of security vulnerabilities?
Available Choices (select all choices that are correct)
Answer: A
Explanation:
One of the trends that has increased the security risks for industrial automation and control systems (IACS) is the integration of these systems with business and enterprise systems, such asenterprise resource planning (ERP), manufacturing execution systems (MES), and supervisory control and data acquisition (SCADA). This integration exposes the IACS to the same threats and vulnerabilities that affect the business and enterprise systems, such as malware, denial-of-service attacks, unauthorized access, and data theft. Moreover, the integration also creates new attack vectors and pathways for adversaries to compromise the IACS, such as through remote access, wireless networks, or third-party devices. Therefore, the integration of IACS with business and enterprise systems is a trend that has caused a significant percentage of security vulnerabilities. References: ISA/IEC 62443 Standards to Secure Your Industrial Control System, page 1-2.
NEW QUESTION # 198
What is a major reason for maintaining an asset inventory baseline in Configuration Management (SP Element 2)?
Answer: D
Explanation:
SP Element 2 in ISA/IEC 62443-2-1 focuses on Configuration Management, with the asset inventory baseline as a foundational requirement.
Step 1: Purpose of an inventory baseline
The inventory baseline documents all hardware, software, firmware, and configuration items that make up the IACS. This establishes a known, trusted state of the system.
Step 2: Architecture visibility
By maintaining this baseline, the asset owner gains a clear and accurate understanding of the IACS architecture, including system components, versions, and dependencies.
Step 3: Why other options are incorrect
Physical access control and user authentication are addressed in different SP Elements. Event management detects anomalies, but it relies on the inventory baseline rather than replacing it.
Thus, the primary reason is to document IACS architecture.
NEW QUESTION # 199
A multinational corporation needs to implement a cybersecurity framework that can be adapted across different countries and industries while allowing continuous improvement. Which feature of the NIST CSF makes it suitable for this purpose?
Answer: D
Explanation:
The NIST Cybersecurity Framework (CSF) is explicitly designed to be flexible, voluntary, and sector- agnostic, making it suitable for diverse environments - including multinational corporations operating in multiple regulatory jurisdictions.
"The Framework is intended to be used by organizations of all sizes, across all sectors and countries. It is technology-neutral and allows for continuous improvement through its tiered implementation and feedback loop."
- NIST Cybersecurity Framework v1.1, Section 1.2 - Framework Overview
This flexibility allows organizations to tailor their implementation to fit their risk appetite, regulatory requirements, and industry practices.

ISA/IEC 62443-2-1 - Cross-reference in aligning with adaptable frameworks like NIST CSF
