質問 # 84
Which layer deals with data format conversion and encryption?
正解：B
解説：
The Presentation layer (Layer 6) of the OSI model is responsible for data format conversion (such as character set translation) and encryption/decryption of messages. This layer ensures that data sent from the application layer of one system can be read by the application layer of another, regardless of differences in data representation.
Reference: ISA/IEC 62443-1-1:2007, Section 3.2.5 (OSI Reference Model), Table 3; ISO/IEC 7498-1:1994.
質問 # 85
Which of the following is an activity that should trigger a review of the CSMS?
Available Choices (select all choices that are correct)
正解：A、B、D
解説：
According to the ISA/IEC 62443-2-1 standard, a review of the CSMS should be triggered by any changes that affect the cybersecurity risk of the industrial automation and control system (IACS), such as new technical controls, organizational restructuring, or security incidents1. Budgeting is not a trigger for CSMS review, unless it impacts the cybersecurity risk level or the CSMS itself2.

質問 # 86
According to the scheme for cybersecurity profiles, which of the following is true about ISA/IEC 62443 security requirements when creating a security profile?
正解：C
解説：
ISA/IEC TR 62443-1-5 defines the rules for creating cybersecurity profiles. The key principle is preservation of standard integrity.
Step 1: Purpose of profiles
Profiles allow selection and scoping of existing requirements for specific industries or applications.
Step 2: Restriction on modification
The technical report explicitly states that no new security requirements may be added, and existing requirements must not be altered. This ensures interoperability, auditability, and certification consistency.
Step 3: Correct approach
Profiles may select, exclude, or contextualize requirements, but they cannot redefine them.
Therefore, Option C is correct.
質問 # 87
In a defense-in-depth strategy, what is the purpose of role-based access control?
Available Choices (select all choices that are correct)
正解：B
解説：
Role-based access control (RBAC) is a method of restricting access to resources based on the roles of individual users within an organization. RBAC assigns permissions and responsibilities to roles, rather than to individual users, and then assigns users to those roles. This way, users can only perform the actions that are relevant and necessary for their role, and not access or modify any other resources that are beyond their scope of authority. RBAC is one of the security countermeasures that can be implemented in a defense-in-depth strategy, which is a layered approach to protect industrial automation and control systems (IACS) from cyber threats. RBAC can help prevent unauthorized access, misuse, or sabotage of IACS resources, as well as reduce the risk of human error or insider attacks.
