NEW QUESTION # 139
Which of the following is a trend that has caused a significant percentage of security vulnerabilities?
Available Choices (select all choices that are correct)

Answer: A

Explanation:
One of the trends that has increased the security risks for industrial automation and control systems (IACS) is the integration of these systems with business and enterprise systems, such asenterprise resource planning (ERP), manufacturing execution systems (MES), and supervisory control and data acquisition (SCADA). This integration exposes the IACS to the same threats and vulnerabilities that affect the business and enterprise systems, such as malware, denial-of-service attacks, unauthorized access, and data theft. Moreover, the integration also creates new attack vectors and pathways for adversaries to compromise the IACS, such as through remote access, wireless networks, or third-party devices. Therefore, the integration of IACS with business and enterprise systems is a trend that has caused a significant percentage of security vulnerabilities. References: ISA/IEC 62443 Standards to Secure Your Industrial Control System, page 1-2.


NEW QUESTION # 140
Which of the following tools has the potential for serious disruption of a control network and should not be used on a live system?
Available Choices (select all choices that are correct)

Answer: C

Explanation:
A vulnerability scanner is a tool that scans a network or a system for known vulnerabilities, such as misconfigurations, outdated software, or weak passwords. A vulnerability scanner can provide valuable information for improving the security posture of a system, but it can also cause serious disruption of a control network if used on a live system. This is because a vulnerability scanner may generate a large amount of network traffic, consume system resources, trigger alarms, or even crash devices by exploiting vulnerabilities. Therefore, a vulnerability scanner should not be used on a live system without proper authorization and precautions. A vulnerability scanner should only be used on a test or isolated network, or during a scheduled maintenance window with minimal impact on the system operation. References: ISA/IEC
62443 Standards to Secure Your Industrial Control System, Module 5: Assessing the Current Security Level, Slide 25.
