Available Choices (select all choices that are correct)

A. Conduits
B. Tunnels
C. Firewalls
D. Pathways

正解：A

質問 # 158
Which of the following is an industry sector-specific standard?
Available Choices (select all choices that are correct)

A. ISA-62443 (EC 62443)
B. NIST SP800-82
C. ISO 27001
D. API 1164

正解：D

解説：
API 1164 is an industry sector-specific standard that provides guidance on the cybersecurity of pipeline supervisory control and data acquisition (SCADA) systems. API stands for American Petroleum Institute, which is the largest U.S. trade association for the oil and natural gas industry. API 1164 was first published in
2004 and revised in 2009 and 2021. The latest version of the standard aligns with the ISA/IEC 62443 series of standards and incorporates the concepts of security levels, zones, and conduits. API 1164 covers the security lifecycle of pipeline SCADA systems, from risk assessment and policy development to implementation and maintenance. The standard also defines roles and responsibilities, security requirements, security controls, and security assessment methods for pipeline SCADA systems.

質問 # 159
Which statement BEST describes the Target Security Protection Ratings?

A. They define the levels of security requirements fulfilled through implementation measures.
B. They represent the actual security levels achieved at a time during operation.
C. They outline the desired levels of system security requirements to be fulfilled during operation.
D. They measure the cost-effectiveness of security investments or implementation measures.

正解：C

解説：
Target Security Levels (SL-T) or Target Security Protection Ratings are defined as the desired security levels that must be achieved for a specific zone or conduit, based on risk assessment and business requirements.
"The Target Security Level (SL-T) represents the desired level of protection against threats for a zone or conduit, to be fulfilled through appropriate security measures."
- ISA/IEC 62443-3-2:2020, Clause 6.5.2 - Target SL Vector Determination They are not the actual achieved level (SL-A), nor are they a measure of cost-effectiveness. SL-Ts guide system designers and implementers in selecting appropriate security controls.

ISA/IEC 62443-3-2:2020 - Clause 6.5.2
ISA/IEC 62443-1-1 - Security Level Types: SL-T, SL-A, SL-C

質問 # 160
What is a major reason for maintaining an asset inventory baseline in Configuration Management (SP Element 2)?

A. To ensure physical access control
B. To enforce user authentication policies
C. To detect security anomalies in event management
D. To document IACS architecture

正解：D

解説：
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.

質問 # 161
Within the National Institute of Standards and Technoloqv Cybersecuritv Framework v1.0 (NIST CSF), what
is the status of the ISA 62443 standards?
Available Choices (select all choices that are correct)

A. They are used as informative references.
B. They are used as normative references.
C. They are not used.
D. They are under consideration for future use.

正解：A
