ISA/IEC 62443 Cybersecurity Fundamentals Specialist Sample Questions (Q32-Q37):

NEW QUESTION # 32
Which activity is part of establishing policy, organization, and awareness?
Available Choices (select all choices that are correct)

  • A. Establish the risk tolerance.
  • B. Implement countermeasures.
  • C. Communicate policies.
  • D. Identify detailed vulnerabilities.

Answer: C

Explanation:
According to the ISA/IEC 62443 Cybersecurity Fundamentals Specialist course, establishing policy, organization, and awareness is one of the four steps of the IACS cybersecurity lifecycle. This step involves defining the cybersecurity policies, roles, and responsibilities, as well as communicating them to the relevant stakeholders. It also involves establishing the risk tolerance level, which is the acceptable level of risk for the organization. Communicating policies and establishing the risk tolerance are both activities that are part of this step. Identifying detailed vulnerabilities and implementing countermeasures are activities that belong to the next steps of the lifecycle, which are assessing the current situation and implementing the cybersecurity program, respectively.

NEW QUESTION # 33
Which characteristic is MOST closely associated with the deployment of a demilitarized zone (DMZ)?
Available Choices (select all choices that are correct)

  • A. Level 4 systems must use the DMZ to communicate with Level 3 and below.
  • B. Internet access through the firewall is allowed.
  • C. Email is prevented, thereby mitigating the risk of phishing attempts.
  • D. Level 0 can only interact with Level 1 through the firewall.

Answer: B

Explanation:
In cybersecurity, a demilitarized zone (DMZ) refers to a physical or logical subnetwork that contains and exposes an organization's external-facing services to an untrusted network, typically the internet. The main characteristic of a DMZ is that it acts as a buffer zone between the public internet and the private network.
This allows for internet access through the firewall while keeping the internal network secure. Internet-facing servers are placed in the DMZ so that they are separated from the rest of the internal network. By doing so, if a server in the DMZ is compromised, the attacker would not have direct access to the internal network. This architecture is commonly used to host services such as web servers, mail servers, and FTP servers. Choice C is the most closely associated with the deployment of a DMZ as it allows for regulated and monitored internet access through a firewall.


NEW QUESTION # 34
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)

  • A. They are used as informative references.
  • B. They are under consideration for future use.
  • C. They are used as normative references.
  • D. They are not used.

Answer: A


NEW QUESTION # 35
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)

  • A. They are used as informative references.
  • B. They are under consideration for future use.
  • C. They are used as normative references.
  • D. They are not used.

Answer: A

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:
