質問 # 128
What is a requirement for product security development lifecycles?
正解：C
解説：
The ISA/IEC 62443-4-1 standard defines the requirements for a secure product development lifecycle for IACS products. One of the core requirements is "risk management" - the systematic process of identifying, evaluating, and mitigating security risks throughout the product lifecycle. This ensures that security is built in from the early design phases through to maintenance and decommissioning. While agile and continuous integration can be useful development methods, they are not specific requirements of the standard. Defense-in- depth is a security principle, not a lifecycle process requirement.
Reference: ISA/IEC 62443-4-1:2018, Section 4.2.3 ("Security risk management").

質問 # 130
What is a feature of an asymmetric key?
Available Choices (select all choices that are correct)
正解：C
解説：
An asymmetric key is a feature of asymmetric cryptography, also known as public-key cryptography, which is a method of encrypting and decrypting data using two different keys: a public key and a private key. The public key can be shared with anyone, while the private key must be kept secret by the owner. The public key and the private key aremathematically related, but it is computationally infeasible to derive one from the other.
Asymmetric cryptography can be used for various purposes, such as digital signatures, key exchange, and encryption. For example, if Alice wants to send a message to Bob, she can use Bob's public key to encrypt the message, and only Bob can decrypt it using his private key. Alternatively, if Bob wants to prove that he is the author of a message, he can use his private key to sign the message, and anyone can verify it using his public key. Asymmetric cryptography has some advantages over symmetric cryptography, which uses the same key for both encryption and decryption. For instance, asymmetric cryptography does not require a secure channel to distribute the keys, and it can provide non-repudiation and authentication. However, asymmetric cryptography also has some drawbacks, such as higher computational complexity, larger key sizes, and higher network overhead.

質問 # 131
Electronic security, as defined in ANSI/ISA-99.00.01:2007. includes which of the following?
Available Choices (select all choices that are correct)
正解：A、B
解説：
In ANSI/ISA-99.00.01:2007, which is part of the ISA/IEC 62443 standards, electronic security encompasses both the technical and human aspects of cybersecurity within industrial automated and control systems (IACS). Option B correctly highlights components such as computers, networks, operating systems, applications, and other programmable configurable components which are intrinsic to the system's electronic security framework. Option C is also correct as it includes the personnel, policies, andprocedures which play a crucial role in securing these systems. This emphasizes that security is not only about the technological solutions but also about managing human elements and organizational processes effectively.ISA/IEC 62443 Cybersecurity Fundamentals References:
* ISA/IEC 62443 standards focus on the holistic nature of security which is clearly supported by including both the technological (Option B) and human elements (Option C) in the definition of electronic security.
質問 # 132
In what step of the development process of the CSMS is "Establish purpose, organizational support, resources, and scope" taken care of?
正解：D
解説：
The first step in the Cyber Security Management System (CSMS) development process is to "Initiate the CSMS program," which involves establishing its purpose, obtaining organizational support, allocating resources, and defining the program's scope. These foundational activities are required to ensure that the program is properly structured and supported before detailed risk assessments or architecture planning are performed.
Reference: ISA/IEC 62443-2-1:2009, Section 5.1 ("Initiate the CSMS program").
