NEW QUESTION # 172
Which of the following is the underlying protocol for Ethernet/IP?
Available Choices (select all choices that are correct)
Answer: A
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:

NEW QUESTION # 173
What programs are MOST effective if they are tailored to the audience, consistent with company policy, and communicated regularly?
Answer: D
Explanation:
Cybersecurity awareness programs are critical for ensuring that all personnel understand and follow security practices. To be effective, these programs must be:
Tailored to roles and responsibilities
Aligned with company policies
Communicated regularly and reinforced
"An effective cybersecurity awareness program is audience-specific, policy-aligned, and continuously reinforced to ensure long-term behavioral change."
- ISA/IEC 62443-2-1:2010, Clause 4.3.3 - Security Training and Awareness These programs are part of the organization's security governance and are essential for building a security- focused culture.

NEW QUESTION # 175
Which statement is TRUE reqardinq application of patches in an IACS environment?
Available Choices (select all choices that are correct)
Answer: D
Explanation:
Patches are software updates that fix bugs, vulnerabilities, or improve performance or functionality. Patches are important for maintaining the security and reliability of an IACS environment, but they also pose some challenges and risks. Applying patches in an IACS environment is not as simple as in an IT environment, because patches may affect the availability, integrity, or safety of the IACS. Therefore, patches should not be applied blindly or automatically, but based on the organization's risk assessment. The risk assessment should consider the following factors: 1
* The severity and likelihood of the vulnerability that the patch addresses
* The impact of the patch on the IACS functionality and performance
* The compatibility of the patch with the IACS components and configuration
* The availability of a backup or recovery plan in case the patch fails or causes problems
* The testing and validation of the patch before applying it to the production system
* The communication and coordination with the stakeholders involved in the patching process
* The documentation and auditing of the patching activities and results References: ISA TR62443-2-3 - Security for industrial automation and control systems, Part 2-3: Patch management in the IACS environment
NEW QUESTION # 176
During the operation of an IACS, who is responsible for executing the Security Protection Scheme (SPS) process measures and responding to emerging risks?
Answer: C
Explanation:
ISA/IEC 62443 clearly assigns operational cybersecurity responsibility to the asset owner. During the Operate and Maintain phase of the IACS lifecycle, the asset owner is accountable for ensuring that cybersecurity controls are executed, monitored, and adapted as risks evolve.
Step 1: Definition of the SPS
IEC 62443-2-2 defines the Security Protection Scheme (SPS) as a documented set of technical, procedural, and physical measures selected to manage cybersecurity risk. While other parties may contribute to its design or implementation, execution during operation is the asset owner's responsibility.
Step 2: Operational accountability
ISA/IEC 62443-2-1 establishes that the asset owner must operate and maintain the IACS security program, including incident handling, vulnerability management, patching, monitoring, and response to emerging threats.
Step 3: Why other roles are incorrect
* Product vendors are responsible for product security, not operational risk response.
* System integrators support design and implementation, not ongoing ownership.
* External auditors assess compliance but do not execute controls.
Step 4: Risk ownership principle
Because the asset owner bears the consequences of downtime, safety incidents, and regulatory impact, the standard assigns them responsibility for executing SPS measures and responding to new risks.
Therefore, Option A is correct.
