질문 # 16
Which is the BEST practice when establishing security zones?
Available Choices (select all choices that are correct)
정답：A
설명：
Security zones are logical groupings of assets that share common security requirements based on factors such as criticality, consequence, vulnerability, and threat. Security zones are used to apply the principle of defense in depth, which means creating multiple layers of protection to prevent or mitigate cyberattacks. By creating security zones, asset owners can isolate the most critical or sensitive assets from the less critical or sensitive ones, and apply different levels of security controls to each zone according to the risk assessment. Security zones are not necessarily aligned with physical network segments, as assets within the same network may have different security requirements. For example, a network segment may contain both a safety instrumented system (SIS) and a human-machine interface (HMI), but the SIS has a higher security requirement than the HMI. Therefore, the SIS and the HMI should be in different security zones, even if they are in the same network segment. Similarly, assets within the same logical communication network may not have the same security requirements, and therefore should not be in the same security zone. For example, a logical communication network may span across multiple physical locations, such as a plant and a corporate office, but the assets in the plant may have higher security requirements than the assets in the office. Therefore, the assets in the plant and the office should be in different security zones, even if they are in the same logical communication network. Finally, all components in a large or complex system should not be in the same security zone, as this would create a single point of failure and expose the entire system to potential cyberattacks. Instead, the components should be divided into smaller and simpler security zones, based on their security requirements, and the communication between the zones should be controlled by conduits.
Conduits are logical or physical connections between security zones that allow data flow and access control.
Conduits should be designed to minimize the attack surface and the potential impact of cyberattacks, by applying security controls such as firewalls, encryption, authentication, and authorization. References:

Available Choices (select all choices that are correct)
정답：A
질문 # 18
Which of the following is an industry sector-specific standard?
Available Choices (select all choices that are correct)
정답：B
설명：
API 1164 is an industry sector-specific standard that provides guidance on the cybersecurity of pipeline supervisory control and data acquisition (SCADA) systems. API stands for American Petroleum Institute, which is the largest U.S. trade association for the oil and natural gas industry. API 1164 was first published in
2004 and revised in 2009 and 2021. The latest version of the standard aligns with the ISA/IEC 62443 series of standards and incorporates the concepts of security levels, zones, and conduits. API 1164 covers the security lifecycle of pipeline SCADA systems, from risk assessment and policy development to implementation and maintenance. The standard also defines roles and responsibilities, security requirements, security controls, and security assessment methods for pipeline SCADA systems.

질문 # 19
What is a commonly used protocol for managing secure data transmission over a Virtual Private Network (VPN)?
Available Choices (select all choices that are correct)
정답：D
설명：
IPSec is a commonly used protocol for managing secure data transmission over a VPN. IPSec stands for Internet Protocol Security and it is a set of standards that define how to encrypt and authenticate data packets that travel between two or more devices over an IP network. IPSec can operate in two modes: transport mode and tunnel mode. In transport mode, IPSec only encrypts the payload of the IP packet, leaving the header intact. In tunnel mode, IPSec encrypts the entire IP packet and encapsulates it in a new IP header. Tunnel mode is more secure and more suitable for VPNs, as it can protect the original source and destination addresses of the IP packet from eavesdropping or spoofing. IPSec uses two main protocols to provide security services: Authentication Header (AH) and Encapsulating Security Payload (ESP). AH provides data integrity and source authentication, but not confidentiality. ESP provides data integrity, source authentication, and confidentiality. IPSec also uses two protocols to establish and manage security associations (SAs), which are the parameters and keys used for encryption and authentication: Internet Key Exchange (IKE) and Internet Security Association and Key Management Protocol (ISAKMP). IKE is a protocol that negotiates and exchanges cryptographic keys between two devices. ISAKMP is a protocol that defines the format and structure of the messages used for key exchange and SA management.

질문 # 20
The ISA/IEC 62443 Profiles Group will include parts starting with which number?
정답：A
설명：
The ISA/IEC 62443 series is structured into logical groups to address different aspects of industrial cybersecurity. Historically, the series was organized into Parts 1 through 4, covering general concepts, management system requirements, system requirements, and component requirements. As the standard evolved, the need arose to address sector-specific and application-specific cybersecurity needs without modifying the core requirements.
To address this, ISA introduced the concept of cybersecurity profiles. These profiles allow industries (such as oil and gas, power, water, or manufacturing) to select and tailor existing ISA/IEC 62443 requirements for their specific operational context while preserving consistency with the base standard.
The Profiles Group is formally designated as ISA/IEC 62443-5-x. This numbering clearly distinguishes profiles from foundational requirements and ensures that:
* No new security requirements are created
* Existing requirements are selected, scoped, and referenced appropriately
* Alignment with Parts 2, 3, and 4 is preserved
By allocating profiles to the 5-x series, ISA ensures modularity and prevents fragmentation of the standard.
Profiles serve as an application layer over existing requirements, enabling consistent adoption across sectors without redefining core security controls.
Parts 3-x and 4-x remain dedicated to system and component requirements, while 6-x does not exist in the published structure for profiles. Therefore, 5-x is the correct and formally defined answer.
