NEW QUESTION # 80
Which ISA/IEC 62443 part covers technical security requirements used by product suppliers, integration service providers, and asset owners?
Answer: A
Explanation:
ISA/IEC 62443-4-2 specifies technical security requirements (TSRs) for individual IACS components such as:
Embedded devices
Software applications
Network components
Host devices
These TSRs are relevant for product suppliers who design the components, integration service providers who implement them, and asset owners who operate them.
"This standard specifies the technical security requirements for components used in an IACS, and is applicable to product suppliers, system integrators, and asset owners responsible for security implementation."
- ISA/IEC 62443-4-2:2018, Clause 1 - Scope
The 62443-3-3 standard complements it by specifying system-level requirements, while 62443-2-4 focuses on service providers and 62443-2-1 on security program management.
References:
ISA/IEC 62443-4-2:2018 - Clause 1
ISA/IEC 62443-4-2 - Table 1: Component types and SRs
ISA/IEC 62443-1-1 - Roles and document mapping
NEW QUESTION # 81
What must be established as part of the risk assessment process?
Answer: A
Explanation:
The ISA/IEC 62443-3-2 standard specifies that a key output of the risk assessment process is the establishment of Target Security Levels (SL-Ts) for each security zone or conduit. These target levels define the minimum cybersecurity requirements necessary to mitigate identified risks to an acceptable level. Total risk elimination is generally not possible; instead, setting SL-Ts allows for structured, risk-based implementation of security controls.
Reference: ISA/IEC 62443-3-2:2020, Section 5.4.4 ("Assignment of Target Security Levels").
NEW QUESTION # 82
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.

NIST CSF v1.1 - Section 1.2
ISA/IEC 62443-2-1 - Cross-reference in aligning with adaptable frameworks like NIST CSF
