ISA/IEC 62443 Cybersecurity Fundamentals Specialist Sample Questions (Q117-Q122):

NEW QUESTION # 117
What is the primary focus of Part 3-2 in the ISA/IEC 62443 series?

A. Technical security requirements for IACS components
B. Cybersecurity risk assessment and system design
C. Secure product development lifecycle requirements
D. Security technologies for IACS

Answer: B

Explanation:
ISA/IEC 62443-3-2 focuses on the cybersecurity risk assessment process, including:
Identifying zones and conduits
Determining the Target Security Levels (SL-T)
Designing the IACS architecture based on risk-based zoning
"Part 3-2 defines a process for conducting cybersecurity risk assessments and designing system architectures that incorporate zones and conduits based on those risks."
- ISA/IEC 62443-3-2:2020, Clause 5 - Risk Assessment Process
This part bridges the gap between risk evaluation and technical implementation.
References:
ISA/IEC 62443-3-2:2020 - Clauses 5.2 to 5.5
ISA/IEC 62443-1-1 - Framework overview

NEW QUESTION # 118
In an IACS system, a typical security conduit consists of which of the following assets?

A. Wiring, routers, switches, and network management devices
B. Power lines, cabinet enclosures, and protective grounds
C. Ferrous, thickwall, and threaded conduit including raceways
D. Controllers, sensors, transmitters, and final control elements

Answer: A

Explanation:
In ISA/IEC 62443, a conduit is a logical or physical communication path used to connect security zones and is typically composed of:
Routers and switches
Network cabling (wiring)
Firewalls and network management devices
"A conduit is used to implement the flow of data between zones, and includes the communication hardware and associated logical controls such as firewalls, switches, and routers."
- ISA/IEC 62443-1-1:2007, Clause 3.3.44 - Conduit
This differs from physical electrical conduits, which are not a cybersecurity concept.
References:
ISA/IEC 62443-1-1:2007 - Clause 3.3.44
ISA/IEC 62443-3-2 - Zone and Conduit Model (Clause 5.3)

NEW QUESTION # 119
Which of the following is an element of monitoring and improving a CSMS?
Available Choices (select all choices that are correct)

A. Review of system logs and other key data files
B. Significant changes in identified risk round in periodic reassessments
C. Restricted access to the industrial control system to an as-needed basis
D. Increase in staff training and security awareness

Answer: A,D

Explanation:
Monitoring and improving a Cybersecurity Management System (CSMS) as per ISA/IEC 62443 standards involves several key activities that ensure the system remains effective and responsive to emerging threats.
Two critical elements of this ongoing process are:
* A. Increase in staff training and security awareness:Regular training and increasing security awareness among staff are vital to maintaining a secure operating environment. This proactive measure helps in reducing human error and enhancing the ability to respond effectively to cybersecurity incidents.
* D. Review of system logs and other key data files:Continuous review and analysis of system logs and other relevant data files are essential for detecting, investigating, and responding to potential security incidents. This monitoring helps in identifying anomalies that may indicate a security breach or operational issues needing attention.

NEW QUESTION # 120
What are three possible entry points (pathways) that could be used for launching a cyber attack?
Available Choices (select all choices that are correct)

A. LAN, WAN, and hard drive
B. LAN, portable media, and wireless
C. LAN, power source, and wireless OD.
D. LAN, portable media, and hard drives

Answer: B

NEW QUESTION # 121
What change was introduced in the second edition (2024) of ISA-62443-2-1 compared to the first edition (2010)?

A. Removal of supply chain security considerations
B. Elimination of duplication of ISMS requirements
C. Introduction of a new PDCA cycle framework
D. Focus only on individual system components rather than overall system

Answer: B

Explanation:
The second edition (2024) of ISA/IEC 62443-2-1 introduced a significant structural improvement by eliminating duplication of Information Security Management System (ISMS) requirements. The first edition (2010) contained content that overlapped substantially with ISO/IEC 27001-style ISMS controls, leading to redundancy and unnecessary implementation burden.
In the updated edition, ISA clarified that 62443-2-1 is not intended to replace a general-purpose ISMS, but rather to extend and specialize it for Industrial Automation and Control Systems (IACS). As a result, duplicated ISMS clauses were removed or streamlined, and the focus shifted to IACS-specific risks, operational realities, and lifecycle concerns.
This change improves:
* Compatibility with existing enterprise ISMS implementations
* Clarity of roles between IT security governance and OT security management
* Practical adoption by asset owners operating both IT and OT environments Importantly, supply chain security, lifecycle management, and organizational governance were not removed.
Instead, they were better aligned and referenced to avoid redundancy. The PDCA model remains implicit but was not newly introduced in 2024.
Thus, the defining change is the elimination of duplicated ISMS requirements, making Option B correct.
