問題 #21
What are the two sublayers of Layer 2?
Available Choices (select all choices that are correct)
答案：C
解題說明：
Layer 2 of the OSI model is the data link layer, which is responsible for transferring data frames between nodes on a network segment. The data link layer is divided into two sublayers: logical link control (LLC) and media access control (MAC). The LLC sublayer deals with issues common to both dedicated and broadcast links, such as framing, flow control, and error control. The MAC sublayer deals with issues specific to broadcast links, such as how to access the shared medium and avoid collisions. The LLC and MAC sublayers are not related to the ISA/IEC 62443 cybersecurity standards, which focus on the security of industrial automation and control systems (IACS).

答案：B
問題 #23
Why is patch management more difficult for IACS than for business systems?
Available Choices (select all choices that are correct)
答案：A
解題說明：
Patch management is the process of applying software updates to fix security vulnerabilities, improve functionality, or enhance performance. Patch management is an essential part of cybersecurity, as unpatched systems can be exploited by malicious actors. However, patch management for industrial automation and control systems (IACS) is more challenging than for business systems, because patching a live automation system can create safety risks. According to the ISA/IEC 62443 standards, patching an IACS may have the following potential impacts1:
* Patching may introduce new vulnerabilities or errors that compromise the availability, integrity, or confidentiality of the IACS.
* Patching may affect the functionality or performance of the IACS, causing unexpected or undesired behavior, such as process shutdowns, slowdowns, or failures.
* Patching may require downtime or reduced operation of the IACS, which may affect production, quality, or profitability.
* Patching may require additional resources, such as personnel, equipment, or testing facilities, which may not be readily available or affordable.
Therefore, patch management for IACS requires careful planning, testing, and validation before applying patches to the operational environment. The ISA/IEC 62443 standards provide guidance and best practices for patch management in the IACS environment, such as1:
* Establishing a patch management program that defines roles, responsibilities, policies, and procedures for patching IACS components and systems.
* Identifying and prioritizing the IACS assets that need patching, based on their criticality, vulnerability, and risk level.
* Evaluating and verifying the patches for compatibility, functionality, and security before applying them to the IACS.
* Implementing and documenting the patching process, including backup, recovery, and rollback procedures, in case of patch failure or adverse effects.
* Monitoring and auditing the patching activities and outcomes, and reporting any issues or incidents.

問題 #24
Safety management staff are stakeholders of what security program development?
Available Choices (select all choices that are correct)
答案：B
問題 #25
Which of the following is an element of security policy, organization, and awareness?
Available Choices (select all choices that are correct)
答案：A
解題說明：
According to the ISA/IEC 62443-2-1 standard, security policy, organization, and awareness is one of the four foundational requirements for an IACS security management system. It defines the "policies, procedures, and organizational structure necessary to support the security program" 1. One of the elements of this requirement is staff training and security awareness, which involves "providing appropriate security education and training to all personnel who have access to or are responsible for IACS components" 1. This element aims to ensure that the staff are aware of the security risks, policies, and procedures, and are able to perform their roles and responsibilities in a secure manner. Staff training and security awareness can include topics such as security principles, threats and vulnerabilities, incident response, password management, physical security, and social engineering 2.
