질문 # 36
Which analysis method is MOST frequently used as an input to a security risk assessment?
Available Choices (select all choices that are correct)
정답：D
질문 # 37
What is TRUE regarding safety systems?
정답：D
설명：
Even the most modern and sophisticated safety systems can be defeated by an attacker. This statement is validated by the discovery of malware specifically targeting safety instrumented systems (SIS), such as the
"Triton/Trisis" malware that compromised the SIS of a petrochemical plant. Safety systems, while designed as independent protection layers, are not immune to cybersecurity vulnerabilities and require specific countermeasures. Integration, such as using Modbus TCP, does not inherently reduce risk to a tolerable level without additional controls.

질문 # 38
Which organization manages the ISASecure conformance certification program?
Available Choices (select all choices that are correct)
정답：D
질문 # 39
What is the name of the protocol that implements serial Modbus over Ethernet?
Available Choices (select all choices that are correct)
정답：A
설명：
MODBUS/TCP is the name of the protocol that implements serial Modbus over Ethernet. MODBUS/TCP is a variant of the Modbus protocol that uses the Transmission Control Protocol (TCP) as the transport layer to encapsulate Modbus messages and send them over Ethernet networks. MODBUS/TCP preserves the Modbus application layer and data model, which means that serial Modbus devices can communicate with MODBUS/TCP devices through a gateway or a converter. MODBUS/TCP is widely used in industrial automation and control systems, as it offers high performance, interoperability, and compatibility with existing Modbus devices.

3.1.21; MODBUS Application Protocol Specification V1.1b3, Section 1.1
질문 # 40
Which statement is TRUE reqardinq application of patches in an IACS environment?
Available Choices (select all choices that are correct)
정답：D
설명：
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
