NEW QUESTION # 194
What does the first group of the ISA/IEC 62443 series focus on?
Answer: B
Explanation:
The ISA/IEC 62443 standards are divided into four main groups: General, Policies and Procedures, System, and Component. The first group, "General," includes foundational standards and technical reports that provide essential concepts, models, terminology, and overall guidance for the rest of the series. This includes parts such as 62443-1-1 (concepts and models), 1-2 (glossary), 1-3 (metrics), and 1-4 (security lifecycle and use cases).
Reference: ISA/IEC 62443-1-1:2007, Section 4.1.2; Official 62443 series structure as published by ISA and IEC.
NEW QUESTION # 195
A national standards body wants to represent its country's interests at an international level and adopt global standards locally. What role does this organization fulfill?
Answer: C
Explanation:
A National Standardization Body (NSB) represents a country's interests in international standards organizations like ISO or IEC, and is responsible for adopting and promoting these standards at the national level.
"A National Standardization Body (NSB) participates in the development of international standards, represents national interests, and facilitates the adoption of international standards as national standards."

In contrast:
A Global SDO (Standards Development Organization) works at the international level A Regulatory Agency enforces rules An Industry Consortium is a private collaboration, not a national entity References:

NEW QUESTION # 196
Which of the following refers to internal rules that govern how an organization protects critical system
resources?
Available Choices (select all choices that are correct)
Answer: C
NEW QUESTION # 197
Which characteristic is MOST closely associated with the deployment of a demilitarized zone (DMZ)?
Available Choices (select all choices that are correct)
Answer: D
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 # 198
Which of the following is NOT a general class of firewalls?
Answer: C
Explanation:
Packet filter, application proxy, and stateful inspection are all recognized types or classes of firewalls in both IT and industrial control environments. A network monitor, on the other hand, is not considered a firewall but rather a tool for observing and analyzing network traffic. It does not provide firewall-like controls for blocking or allowing traffic.
Reference: ISA/IEC 62443-3-3:2013, Section 4.2.3.3 ("Types of firewalls"); ISA/IEC 62443-1-1:2007, Section 3.2.6.
