ISA/IEC 62443 Cybersecurity Fundamentals Specialist Sample Questions (Q17-Q22):

NEW QUESTION # 17
Which of the following is an industry sector-specific standard?
Available Choices (select all choices that are correct)

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

Answer: C

Explanation:
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.

NEW QUESTION # 18
Which of the following staff is NOT mentioned as a stakeholder in the CSMS Program?

A. Physical security
B. IT security
C. Marketing
D. Operations

Answer: C

Explanation:
Within the context of the Cyber Security Management System (CSMS) as defined in ISA/IEC 62443-2-1, the primary stakeholders include operations staff (responsible for system operations), IT security staff (for information technology and cybersecurity controls), and physical security staff (for site access and physical barriers). Marketing staff are not typically listed as stakeholders in the design, implementation, or maintenance of the CSMS, since their role does not directly influence the security posture of industrial control systems. This is outlined in the roles and responsibilities sections of the standard.
Reference: ISA/IEC 62443-2-1:2009, Section 4.3.2 ("CSMS Program Stakeholders" and Table 1 - Typical Stakeholders).

NEW QUESTION # 19
Security Levels (SLs) are broken down into which three types?
Available Choices (select all choices that are correct)

A. Target.capability, and achieved
B. Target.capacity, and achieved
C. SL-1, SL-2, and SL-3
D. Target.capability, and availability

Answer: A

Explanation:
Security Levels (SLs) are a way of expressing the security performance of an industrial automation and control system (IACS) or its components. SLs are broken down into three types: target, capability, and achieved1.
* Target SL is the level of security performance that is required for a system or component to protect against a specific threat scenario. The target SL is determined by conducting a risk assessment that considers the likelihood and impact of potential security incidents1.
* Capability SL is the level of security performance that a system or component can provide based on its design and implementation. The capability SL is determined by evaluating the security functions and features of the system or component against a set of security requirements1.
* Achieved SL is the level of security performance that a system or component actually provides in its operational environment. The achieved SL is determined by verifying that the system or component is properly installed, configured, maintained, and monitored1.

NEW QUESTION # 20
Which of the following refers to internal rules that govern how an organization protects critical system
resources?
Available Choices (select all choices that are correct)

A. Legislation
B. Formal guidance
C. Security policy
D- Code of conduct

Answer: C

NEW QUESTION # 21
What is OPC?
Available Choices (select all choices that are correct)

A. An open standard protocol for the communication of real-time data between devices from different manufacturers
B. A vendor-specific proprietary protocol for the communication of real-time plant data between control devices
C. An open standard serial communications protocol widely used in industrial manufacturing environments
D. An open standard protocol for real-time field bus communication between automation technology devices

Answer: A

Explanation:
OPC stands for Open Platform Communications, and it is a series of standards and specifications for industrial telecommunication based on Object Linking and Embedding (OLE) for process control. It allows the communication of real-time data between devices from different manufacturers using various data transportation technologies, such as Microsoft's OLE, COM, DCOM, .NET, XML, and TCP123. OPC is not a protocolitself, but rather a standardized approach for data connectivity supported by the OPC Foundation3. OPC is widely used in industrial automation and control systems, as well as other industries, to achieve interoperability and integration between different applications and devices3.
A is incorrect, because OPC is not a field bus protocol, but rather a standard for data exchange between devices that may use different field bus protocols, such as Modbus, Profibus, or Ethernet/IP2. C is incorrect, because OPC is not a serial communications protocol, but rather a standard that can use various data transportation technologies, including serial, Ethernet, or wireless2. D is incorrect, because OPC is not a vendor-specific proprietary protocol, but rather an open standard that can be implemented by any vendor or device that supports the OPC specifications3.
