NEW QUESTION # 89
According to ISA/IEC TR 62443-1-5, which documents can be referenced when creating a security profile?
Answer: D
Explanation:
ISA/IEC TR 62443-1-5 provides formal guidance on the creation and structure of cybersecurity profiles within the ISA/IEC 62443 framework. A security profile is intended to tailor existing requirements to a specific industry sector, application, or use case without altering the integrity of the base standard.
Step 1: Purpose of a security profile
The technical report clarifies that profiles are selections and combinations of existing requirements, not a mechanism to invent new controls. Profiles ensure consistent application of ISA/IEC 62443 while addressing sector-specific risk, regulatory, or operational needs.
Step 2: Authorized source documents
TR 62443-1-5 explicitly states that security profiles may reference requirements from:
* ISA/IEC 62443-2-1 (asset owner security program requirements)
* ISA/IEC 62443-2-4 (service provider requirements)
* ISA/IEC 62443-3-3 (system security requirements)
* ISA/IEC 62443-4-1 (secure product development lifecycle)
* ISA/IEC 62443-4-2 (technical component requirements)
These documents collectively cover organizational, system, and component security.
Step 3: Why other options are incorrect
* Limiting profiles to only Parts 3-3 and 4-1 excludes governance and lifecycle requirements.
* Parts 1-1 and 1-2 are foundational and definitional, not requirement sources.
* Referencing standards outside the 62443 family violates the intent of maintaining internal consistency.
Step 4: Standard integrity
By restricting profiles to these documents, ISA ensures profiles remain interoperable, auditable, and certifiable.
Thus, Option C is the only correct answer.
NEW QUESTION # 90
Which of the following is NOT listed under Organizational Security Measures (SP Element 1)?
Answer: A
Explanation:
ISA/IEC 62443-2-1 defines SP Element 1 - Organizational Security Measures as the set of governance, policy, and people-focused controls that establish the foundation of an IACS Security Program. These measures are organizational in nature and are intended to create accountability, awareness, and structured risk management.
Step 1: Scope of SP Element 1
SP Element 1 includes activities such as:
* Security policy definition
* Roles and responsibilities
* Personnel security (e.g., background checks)
* Security awareness and training
* Supply chain security governance
These controls ensure that people, processes, and third-party relationships support cybersecurity objectives.
Step 2: Why malware protection does not belong here
Malware protection is a technical control, not an organizational measure. In ISA/IEC 62443, malware protection is addressed under SP Element 4 - Component Hardening, which focuses on endpoint protection, anti-malware mechanisms, and secure configurations.
Step 3: Why the other options are valid
* Background checks are explicitly part of personnel security.
* Supply chain security is a key organizational concern.
* Security awareness training ensures staff understand their responsibilities.
Therefore, Malware protection is not listed under SP Element 1.

NEW QUESTION # 92
What is a key feature of the NIS2 Directive?
Answer: B
Explanation:
The NIS2 Directive, an update to the European Union's cybersecurity directive, introduces several new requirements, including the establishment of a cyber crisis management framework at both national and EU levels. This is designed to coordinate effective responses to major cybersecurity incidents and crises. NIS2 goes beyond mandating compliance or focusing only on physical security and emphasizes collaboration between the public and private sectors.
Reference: NIS2 Directive (Directive (EU) 2022/2555), Articles 9-11, and official ENISA documentation.
