Available Choices (select all choices that are correct) Modern IDS recognize IACS devices by default. They are very inexpensive to design and deploy. They are effective against known vulnerabilities. They require a small amount of care and feeding Answer: C Explanation Intrusion detection systems (IDS) are tools that monitor network traffic and detect suspicious or malicious activity based on predefined rules or signatures. They are effective against known vulnerabilities, as they can alert the system administrators or security personnel when they encounter a match with a known attack pattern or behavior. However, IDS have some limitations and challenges, especially when applied to industrial automation and control systems (IACS). Some of these are: Modern IDS do not recognize IACS devices by default, as they are designed for general-purpose IT networks and protocols. Therefore, they may generate false positives or negatives when dealing with IACS-specific devices, protocols, or traffic patterns. To overcome this, IDS need to be customized or adapted to the IACS environment and context, which may require additional expertise and resources. They are not very inexpensive to design and deploy, as they require careful planning, configuration, testing, and maintenance. They also need to be integrated with other security tools and processes, such as firewalls, antivirus, patch management, incident response, etc. Moreover, they may introduce additional costs and risks, such as network performance degradation, data privacy issues, or legal liabilities. They are not effective against unknown or zero-day vulnerabilities, as they rely on predefined rules or signatures that may not cover all possible attack scenarios or techniques. Therefore, they may fail to detect ISA - ISA-IEC-62443 Pass Exam 2 of 9 Verified Solution - 100% Result A. B. C. D. novel or sophisticated attacks that exploit new or undiscovered vulnerabilities. To mitigate this, IDS need to be complemented with other security measures, such as anomaly detection, threat intelligence, or machine learning. They require a significant amount of care and feeding, as they need to be constantly updated, tuned, and monitored. They also generate a large amount of data and alerts, which may overwhelm the system administrators or security personnel. Therefore, they need to be supported by adequate tools and processes, such as data analysis, alert filtering, prioritization, correlation, or visualization.

Which type of firewall would BEST suit this need? General-purpose software firewall Unidirectional gateway (data diode) IACS-specific firewall with deep packet inspection Basic packet filter firewall without protocol awareness Answer: C Explanation ISA/IEC 62443 recommends protocol-aware security controls for IACS networks to protect real-time communications. Step 1: ICS protocol awareness IACS-specific firewalls understand industrial protocols such as Modbus, DNP3, and IEC 61850, allowing precise control without breaking deterministic behavior. Step 2: Deep packet inspection (DPI) DPI enables inspection of commands and function codes, blocking unauthorized actions while allowing legitimate traffic. Step 3: Why other options are unsuitable General-purpose firewalls lack protocol awareness. Data diodes restrict bidirectional control. Basic packet filters cannot inspect commands. Therefore, the correct choice is IACS-specific firewall with deep packet inspection. ISA - ISA-IEC-62443 Pass Exam 3 of 9 Verified Solution - 100% Result A. B. C. D. A. B. C. D. Question #:3 - [IEC 62443 Overview and Terminology] What do the tiers in the NIST CSF represent? Stages of incident response Categories of cybersecurity threats An organization's cybersecurity profile Different types of cybersecurity software Answer: C Explanation In the NIST Cybersecurity Framework (CSF), “tiers” represent the degree to which an organization’s cybersecurity risk management practices exhibit the characteristics defined in the framework (such as risk awareness, repeatability, and adaptability). Tiers range from Partial (Tier 1) to Adaptive (Tier 4) and describe the organization's overall cybersecurity maturity or profile. Reference: NIST CSF v1.1, Section 2.2 (“Framework Implementation Tiers”); ISA/IEC 62443-1-1:2007, Section 4.2.7. Question #:4 - [Secure Product Development and Integration] In which layer is the physical address assigned? Available Choices (select all choices that are correct) Layer 1 Layer 2 Layer 3 Layer 7 Answer: B Explanation According to the OSI model, the physical address is assigned in the layer 2, also known as the data link layer. The physical address is a unique identifier for each device on a network, such as a MAC address or a serial number. The data link layer is responsible for transferring data between adjacent nodes on a network, using the physical address to identify the source and destination of each frame. The data link layer also provides ISA - ISA-IEC-62443 Pass Exam 4 of 9 Verified Solution - 100% Result A. B. C. D. error detection and correction, flow control, and media access control.

Question #:5 - [IEC 62443 Overview and Terminology] Which protocol is commonly used for managing the security of message transmission on the Internet via web browsers? TLS L2TP PPTP IPsec Answer: A Explanation Transport Layer Security (TLS) is the primary cryptographic protocol used to secure web-based communications such as HTTPS in web browsers. From ISA/IEC 62443-3-3 (System Security Requirements and Security Levels), Annex B: “TLS provides confidentiality, integrity, and authentication for communications over untrusted networks. It is commonly used to secure HTTPS, SMTP, and other application protocols.” TLS superseded SSL and is the backbone of secure data transmission over the Internet. Incorrect Options: B. L2TP – Used for VPNs; not typically browser-related. C. PPTP – An older VPN protocol, not used for browser encryption. D. IPsec – Used to secure IP traffic at the network layer; not directly used in browser-based communication.

Question #:6 - [Foundational Requirements and Technical Security Controls] Under User Access Control (SP Element 6), which of the following is included in USER 1 — Identification and Authentication? Backup restoration Password protection Mutual authentication Incident handling and response Answer: B Explanation SP Element 6 in ISA/IEC 62443-2-1 addresses User Access Control, ensuring that only authorized users can access IACS resources. Step 1: Definition of USER 1 USER 1 corresponds to Identification and Authentication Control (IAC), the first foundational requirement. It focuses on verifying the identity of users before granting access. Step 2: Password protection Password mechanisms are a fundamental form of user authentication and are explicitly included under identification and authentication requirements. Step 3: Why other options are incorrect Mutual authentication applies to system-to-system authentication. Backup restoration and incident handling belong to different SP Elements. Step 4: Security intent By enforcing password protection, the asset owner ensures accountability, traceability, and prevention of unauthorized access. Therefore, the correct answer is Password protection. Question #:7 - [Risk Management and Security Lifecycle] What are the two elements of the risk analysis category of an IACS? Risk evaluation and risk identification Business rationale and risk reduction and avoidance ISA - ISA-IEC-62443 Pass Exam 6 of 9 Verified Solution - 100% Result C. D. A. B. C. D. Business rationale and risk identification and classification Business recovery and risk elimination or mitigation Answer: C Explanation According to ISA/IEC 62443-3-2, the risk analysis phase in the IACS security lifecycle includes both the business rationale and the risk identification and classification. This ensures that risk decisions are based not only on technical vulnerability but also on business impact and operational context. “The risk analysis process includes identification and classification of risks based on a defined business rationale. This ensures that the protection requirements are aligned with the organization’s risk tolerance and operational priorities.” — ISA/IEC 62443-3-2:2020, Section 6.4 – Risk Assessment and SL Targeting The term business rationale refers to understanding the value and criticality of the asset or system in order to make informed security decisions.

Asset model Zone model Security level model Reference architecture Answer: A Explanation 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.
