NEW QUESTION # 218
A company is developing an automation solution and wants to align its cybersecurity efforts with ISA/IEC
62443 standards. Which lifecycle phases should be integrated into their project plan to cover both security and automation solution security comprehensively?
Answer: B
Explanation:
ISA/IEC 62443 is explicitly lifecycle-based, requiring cybersecurity considerations to be integrated across all phases of an automation solution's lifecycle. This includes concept, design, implementation, verification, operation, maintenance, and decommissioning.
Step 1: Lifecycle philosophy of ISA/IEC 62443
The standard recognizes that cybersecurity risks emerge and evolve throughout the system lifecycle.
Addressing security in only one phase leaves gaps that attackers can exploit.
Step 2: Design and implementation are not sufficient
While secure architecture and configuration are critical, they must be supported by secure development practices, verification, operational procedures, incident response, patching, and change management.
Step 3: Operational importance
Many cybersecurity failures occur during operation due to poor maintenance, weak access control, or unmanaged changes. ISA/IEC 62443-2-1 and 3-3 explicitly address these phases.
Step 4: End-of-life considerations
Decommissioning must also be planned to ensure data, credentials, and access paths are securely removed.
Because the standard spans management (2-x), system (3-x), and component (4-x) requirements across the lifecycle, all phases must be integrated.
NEW QUESTION # 219
Which of the following is an industry sector-specific standard?
Available Choices (select all choices that are correct)
Answer: B
Explanation:
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.

NEW QUESTION # 220
Which of the following BEST describes a control system?
Answer: A
Explanation:
A control system, in the context of ISA/IEC 62443, refers to the hardware and software components of an Industrial Automation and Control System (IACS). This includes PLCs, SCADA, DCS, HMIs, sensors, actuators, and supporting networks and applications used to monitor and control physical processes.
Reference: ISA/IEC 62443-1-1:2007, Section 3.2.1 (Definition of control system and IACS).
