질문 # 87
As related to IACS Maintenance Service Providers, when do maintenance activities generally start?
정답：C
설명：
Maintenance service activities typically begin after the system is deployed and handed over to the asset owner. This is aligned with the Operation and Maintenance phase of the IACS lifecycle.
"Maintenance service providers typically become responsible for cybersecurity-related activities after the asset owner takes ownership of the system, following handover."
- ISA/IEC 62443-2-4:2015, Clause 4.2.3 - Transition and Handover
Prior to handover, integrators and product suppliers manage the system. Maintenance providers take over only post-commissioning.

What change was introduced in the second edition (2024) of ISA-62443-2-1 compared to the first edition (2010)?
정답：B
설명：
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.
질문 # 89
What impact do increasing cybercrime attacks have?
정답：D
설명：
Increasing cybercrime attacks have a significant impact on suppliers of essential services, including those in energy, water, transportation, and manufacturing. ISA/IEC 62443 and related critical infrastructure guidance highlight that attackers are increasingly targeting organizations whose disruption can have widespread societal consequences. While cybercrime can drive organizations to improve cybersecurity, the main documented impact is the risk to essential services and infrastructure.
Reference: ISA/IEC 62443-1-1:2007, Section 4.4; NIST CSF, Section 1.0.
질문 # 90
A company discovers malware on a portable USB device used within their IACS environment. According to the document, which SP Element and controls would be MOST relevant to address this issue?
정답：A
설명：
ISA/IEC 62443-2-1 defines SP Element 4 as covering component hardening, malware protection, and the secure use of portable and mobile media. Malware introduced through USB devices is a well-known attack vector in IACS environments, and the standard addresses this risk explicitly through preventive controls rather than only reactive measures.
Step 1: Nature of the threat
Portable media such as USB drives bypass network-based defenses and can introduce malware directly into critical control systems. ISA/IEC 62443 recognizes this as a high-risk vector, especially in air-gapped or semi- isolated systems.
Step 2: SP Element 4 scope
SP Element 4 requires asset owners to implement technical controls such as:
* Restrictions on the use of portable media
* Use of dedicated, controlled media
* Malware scanning before use
* Hardening of endpoints to prevent unauthorized execution
Step 3: Why other SP Elements are secondary
* SP Element 1 focuses on anomaly detection, not prevention.
* SP Element 2 concerns inventory accuracy.
* SP Element 7 applies after an incident has occurred.
Step 4: Preventive emphasis
The standard prioritizes prevention of malware introduction through controlled media usage, making SP Element 4 the most relevant.
질문 # 91
After receiving an approved patch from the JACS vendor, what is BEST practice for the asset owner to follow?
정답：D
설명：
According to the ISA/IEC 62443 Cybersecurity Fundamentals Specialist resources, patches are software updates that fix bugs, vulnerabilities, or improve performance of a system. Patches are classified into three categories based on their urgency and impact: low, medium, and high. Low priority patches are those that have minimal or no impact on the system functionality or security, and can be applied at the next scheduled maintenance. Medium priority patches are those that have moderate impact on the system functionality or security, and should be applied within a reasonable time frame, such as three months. High priority patches are those that have significant or critical impact on the system functionality or security, and should be applied as soon as possible, preferably at the first unscheduled outage. Applying patches in a timely manner is a best practice for maintaining the security and reliability of an industrial automation and control system (IACS). References:
