NEW QUESTION # 28
What does IACS stand for?
Answer: C
Explanation:
IACS stands for "Industrial Automation and Control Systems." The ISA/IEC 62443 series defines IACS as systems used for industrial automation, process control, and related functions. These include systems such as Distributed Control Systems (DCS), SCADA systems, and PLCs. The term encompasses all electronic systems, networks, and equipment used to automate industrial processes.
Reference: ISA/IEC 62443-1-1:2007, Section 3.2.1 (Definitions and Abbreviations); Glossary entry for
"IACS."
NEW QUESTION # 29
How many security levels are in the ISASecure certification program?
Available Choices (select all choices that are correct)
Answer: D
Explanation:
The ISASecure certification program, aligned with the ISA/IEC 62443 standards, defines three distinct security levels that categorize the robustness of industrial control systems against known cybersecurity threats.
These levels are designed to provide a scalable approach to securing industrial automation and control systems, with each level offering a higher degree of security. The levels are typically identified as SL1 (Security Level 1), SL2 (Security Level 2), and SL3 (Security Level 3), each addressing increasingly stringent security capabilities and resilience against cyber attacks.
NEW QUESTION # 30
Which of the following is an industry sector-specific standard?
Available Choices (select all choices that are correct)
Answer: C
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 # 31
Which is the PRIMARY responsibility of the network layer of the Open Systems Interconnection (OSI)
model?
Available Choices (select all choices that are correct)
Answer: D
NEW QUESTION # 32
Which is a PRIMARY reason why network security is important in IACS environments?
Available Choices (select all choices that are correct)
Answer: C
Explanation:
Network security is important in IACS environments because PLCs, or programmable logic controllers, are devices that control physical processes and equipment in industrial settings. PLCs under cyber attack can have costly and dangerous impacts, such as disrupting production, damaging equipment, compromising safety, and harming the environment. Therefore, network security is essential to protect PLCs and other IACS components from unauthorized access, modification, or disruption. The other choices are not primary reasons why network security is important in IACS environments. PLCs are not inherently unreliable, but they can be affected by environmental factors, such as temperature, humidity, and electromagnetic interference. PLCs are programmed using ladder logic, which is a graphical programming language that resembles electrical schematics. PLCs use serial or Ethernet communications methods, depending on the type and age of the device, to communicate with other IACS components, such as human-machine interfaces (HMIs), supervisory control and data acquisition (SCADA) systems, and distributed control systems (DCSs).
