NEW QUESTION # 84
Which of the following technologies is no longer considered secure?
Answer: C
Explanation:
Secure Sockets Layer (SSL) is no longer considered secure due to known vulnerabilities and cryptographic weaknesses. Modern standards require the use of newer versions of Transport Layer Security (TLS), and similarly, DES is deprecated for strong security. However, the best and most universally referenced example is SSL, as major industry and regulatory bodies recommend disabling SSL entirely in favor of TLS 1.2 or above.
Reference: ISA/IEC 62443-3-3:2013, Section 4.2.3.7 ("Cryptographic protections"); NIST SP 800-52 Rev. 2.

NEW QUESTION # 86
Within the National Institute of Standards and Technoloqv Cybersecuritv Framework v1.0 (NIST CSF), what is the status of the ISA 62443 standards?
Available Choices (select all choices that are correct)
Answer: C
Explanation:
The NIST CSF is a voluntary framework that provides a set of standards, guidelines, and best practices to help organizations manage cybersecurity risks. The NIST CSF consists of five core functions: Identify, Protect, Detect, Respond, and Recover. Each function is further divided into categories and subcategories that describe specific outcomes and activities. The NIST CSF also provides informative references that link the subcategories to existing standards, guidelines, and practices that can help organizations achieve the desired outcomes. The informative references are not mandatory or exhaustive, but rather serve as examples of possible sources of guidance. The ISA 62443 standards are used as informative references in the NIST CSF v1.0 for several subcategories, especially in the Protect and Detect functions. The ISA 62443 standards are a series of standards that provide a framework for securing industrial automation and control systems (IACS).
The ISA 62443 standards cover various aspects of IACS security, such as terminology, concepts, requirements, policies, procedures, and technical specifications. The ISA 62443 standards are aligned with the NIST CSF in terms of the core functions and the risk-based approach. Therefore, the ISA 62443 standards can provide useful guidance and best practices for organizations that use IACS and want to implement the NIST CSF. References:

NEW QUESTION # 87
What is a requirement for product security development lifecycles?
Answer: B
Explanation:
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").
