Answer: D
NEW QUESTION # 193
How many maturity levels (ML) are established for evaluation criteria according to ISA/IEC 62443-2-4?
Answer: C
Explanation:
ISA/IEC 62443-2-4 defines four Maturity Levels (ML1 to ML4) for evaluating the processes and practices of service providers (such as integrators and maintenance organizations). These maturity levels assess the consistency, documentation, and effectiveness of processes, ranging from "Initial" (ML1) to "Improving" (ML4).
Reference: ISA/IEC 62443-2-4:2015, Section 5.2 ("Process Maturity Levels"), Table 3.
NEW QUESTION # 194
What is a key feature of the NIS2 Directive?
Answer: B
Explanation:
The NIS2 Directive, an update to the European Union's cybersecurity directive, introduces several new requirements, including the establishment of a cyber crisis management framework at both national and EU levels. This is designed to coordinate effective responses to major cybersecurity incidents and crises. NIS2 goes beyond mandating compliance or focusing only on physical security and emphasizes collaboration between the public and private sectors.
Reference: NIS2 Directive (Directive (EU) 2022/2555), Articles 9-11, and official ENISA documentation.
NEW QUESTION # 195
Which is the BEST practice when establishing security zones?
Available Choices (select all choices that are correct)
Answer: C
Explanation:
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:

NEW QUESTION # 196
What does the abbreviation CSMS round in ISA 62443-2-1 represent?
Available Choices (select all choices that are correct)
Answer: C
Explanation:
The abbreviation CSMS stands for Cyber Security Management System in ISA 62443-2-1. This standard defines the elements necessary to establish a CSMS for industrial automation and control systems (IACS) and provides guidance on how to develop those elements123. A CSMS is a collection of policies, procedures, practices, and personnel that are responsible for ensuring the security of IACS throughout their lifecycle24.
