NEW QUESTION # 147
Which of the following is NOT listed under Organizational Security Measures (SP Element 1)?
Answer: A
Explanation:
SP Element 1 - Organizational Security Measures focuses on policies, roles, and governance at the organizational level. It includes:
Background checks
Security awareness training
Supply chain security governance
However, malware protection is not considered part of SP Element 1, as it falls under technical or system integrity controls, typically found in SP Element 4 (System Integrity).
"SP Element 1 includes activities such as assigning roles and responsibilities, background checks, training, and supply chain oversight - not technical malware defenses."

NEW QUESTION # 148
According to ISA/IEC TR 62443-1-5, which documents can be referenced when creating a security profile?
Answer: A
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 # 150
Which part of the ISA/IEC 62443 series describes a methodology to develop quantitative metrics?
Answer: C
Explanation:
ISA/IEC 62443-1-3 specifically provides guidance on developing quantitative metrics for evaluating the effectiveness of IACS security programs. This part introduces models and methods to create meaningful security program ratings, allowing organizations to quantitatively measure their security maturity and the effectiveness of security controls over time.

NEW QUESTION # 151
Which of the following is the underlying protocol for Ethernet/IP?
Available Choices (select all choices that are correct)
Answer: C
Explanation:
Ethernet/IP is an industrial network protocol that adapts the Common Industrial Protocol (CIP) to standard Ethernet. CIP is an object-oriented protocol that provides a unified communication architecture for various industrial automation applications, such as control, safety, security, energy, synchronization and motion, information and network management. CIP defines a set of messages and services for interacting with devices and data on the network, as well as a set of device profiles for consistent implementation of automation functions across different products. Ethernet/IP uses the transport and control protocols of standard Ethernet, such as TCP/IP and IEEE 802.3, to define the features and functions for its lower layers. Ethernet/IP also uses UDP to transport I/O messages and supports various network topologies, such as star, linear, ring and wireless.
Ethernet/IP is one of the leading industrial protocols in the United States and is widely used in a range of industries, such as factory, hybrid and process. Ethernet/IP is managed by ODVA, Inc., a global trade and standards development organization. References:
