203. Frage
What is Modbus?
Antwort: C
Begründung:
Modbus is a serial communications protocol originally published by Modicon (now Schneider Electric) in
1979 for use with its programmable logic controllers (PLCs). It has become a de facto standard protocol for communication between industrial electronic devices. Modbus allows devices, such as sensors and instruments, to communicate their data to a controller or computer. The protocol can operate over serial lines (RS-232, RS-485) and has been extended for TCP/IP networks (Modbus TCP). It is not a programming language, network security standard, or a type of industrial machinery. Its simplicity and open nature have made it widespread in industrial environments, but it has minimal built-in security, which is a significant consideration in cybersecurity for industrial control systems.
Reference: ISA/IEC 62443-3-3:2013, Section 4.2.3, and ISA-62443-1-1:2007, Section 3.2.1.
204. Frage
What are three possible entry points (pathways) that could be used for launching a cyber attack?
Available Choices (select all choices that are correct)
Antwort: B
Begründung:
A cyber attack is an attempt to compromise the confidentiality, integrity, or availability of a computer system or network by exploiting its vulnerabilities. A cyber attack can be launched from various entry points, which are the pathways that allow an attacker to access a target system or network. According to the ISA/IEC 62443-
3-2 standard, which defines a method for conducting a security risk assessment for industrial automation and control systems (IACS), some of the possible entry points for a cyber attack are:
* LAN: A local area network (LAN) is a network that connects devices within a limited geographic area, such as a building or a campus. A LAN can be an entry point for a cyber attack if an attacker gains physical or logical access to the network devices, such as switches, routers, firewalls, or servers. An attacker can use various techniques to access a LAN, such as network scanning, spoofing, sniffing, or hijacking. An attacker can also exploit vulnerabilities in the network protocols, services, or applications that run on the LAN. A cyber attack on a LAN can affect the communication and operation of the devices and systems connected to the network, such as IACS.
* Portable media: Portable media are removable storage devices that can be used to transfer data between different systems or devices, such as USB flash drives, CDs, DVDs, or external hard drives. Portable media can be an entry point for a cyber attack if an attacker uses them to introduce malicious code or data into a target system or device. An attacker can use various techniques to infect portable media, such as autorun, social engineering, or physical tampering. An attacker can also exploit vulnerabilities in the operating systems, drivers, or applications that interact with portable media. A cyber attack using portable media can affect the functionality and security of the systems or devices that use them, such as IACS.
* Wireless: Wireless is a technology that enables communication and data transmission without physical wires or cables, such as Wi-Fi, Bluetooth, or cellular networks. Wireless can be an entry point for a cyber attack if an attacker intercepts, modifies, or disrupts the wireless signals or data. An attacker can use various techniques to access wireless networks or devices, such as cracking, jamming, or eavesdropping. An attacker can also exploit vulnerabilities in the wireless protocols, standards, or encryption methods. A cyber attack on wireless can affect the availability and reliability of the wireless communication and data transmission, such as IACS.
Therefore, LAN, portable media, and wireless are three possible entry points that could be used for launching a cyber attack. References:

205. Frage
Which model describes relationships between assets within an industrial automation and control system?
Antwort: D
Begründung:
The asset model is used in ISA/IEC 62443 to represent and describe the relationships and dependencies between different assets in an IACS environment. This model helps organizations identify and document assets, their interconnections, and their significance for operational and cybersecurity purposes. The zone model builds upon the asset model for segmentation, but the asset model itself establishes the foundational relationships.
Reference: ISA/IEC 62443-1-1:2007, Section 4.3.1 ("Asset Model"); Figure 3 ("Example asset model for IACS").
206. Frage
Which ISA/IEC 62443 part covers technical security requirements used by product suppliers, integration service providers, and asset owners?
Antwort: C
Begründung:
ISA/IEC 62443-4-2 specifies technical security requirements (TSRs) for individual IACS components such as:
Embedded devices
Software applications
Network components
Host devices
These TSRs are relevant for product suppliers who design the components, integration service providers who implement them, and asset owners who operate them.
"This standard specifies the technical security requirements for components used in an IACS, and is applicable to product suppliers, system integrators, and asset owners responsible for security implementation."
- ISA/IEC 62443-4-2:2018, Clause 1 - Scope
The 62443-3-3 standard complements it by specifying system-level requirements, while 62443-2-4 focuses on service providers and 62443-2-1 on security program management.
