Question 111

Which of the following is an element of monitoring and improving a CSMS?
Available Choices (select all choices that are correct)

A.Increase in staff training and security awareness
B.Restricted access to the industrial control system to an as-needed basis
C.Significant changes in identified risk round in periodic reassessments
D.Review of system logs and other key data files

Correct Answer: A,D

Monitoring and improving a Cybersecurity Management System (CSMS) as per ISA/IEC 62443 standards involves several key activities that ensure the system remains effective and responsive to emerging threats.
Two critical elements of this ongoing process are:
A). Increase in staff training and security awareness: Regular training and increasing security awareness among staff are vital to maintaining a secure operating environment. This proactive measure helps in reducing human error and enhancing the ability to respond effectively to cybersecurity incidents.
D). Review of system logs and other key data files: Continuous review and analysis of system logs and other relevant data files are essential for detecting, investigating, and responding to potential security incidents.
This monitoring helps in identifying anomalies that may indicate a security breach or operational issues needing attention.

Question 113

Which of the following BEST describes 'Vulnerability'?

A.An exploitable flaw in management
B.The result that occurs from a particular incident
C.The potential for violation of security
D.An event that could breach security

Correct Answer: C

According to IEC 62443-1-1, a vulnerability is defined as:
"A weakness in an asset or in the protective measures associated with that asset that can be exploited by a threat source." More broadly, it represents the potential for a violation of security, rather than a guaranteed breach or specific event.
This aligns with the understanding in cybersecurity risk management - a vulnerability does not equate to an incident or result, but rather a potential that could be exploited.
Incorrect Options:
A). An exploitable flaw in management - Too narrow; vulnerabilities exist in systems, software, devices, not just management.
B). An event that could breach security - That's a threat, not a vulnerability.
D). The result that occurs from a particular incident - That would be considered a consequence or impact, not the vulnerability itself.

Question 114

Which is a physical layer standard for serial communications between two or more devices?
Available Choices (select all choices that are correct)

A.RS232
B.RS235
C.RS432
D.RS435

Correct Answer: A

RS232 is a physical layer standard for serial communication between two or more devices. It defines the electrical characteristics, timing, and pinout of connectors for serial data transmission. RS232 is widely used in industrial communication devices, such as PLCs, measuring instruments, and network servers. RS232 allows only one master and one slave to communicate on each line, and operates in a full duplex mode. RS232 haslower transmission speed, shorter maximum cable length, and larger voltage swing than later standards such as RS422 and RS485123 References: 1: Basics of RS232, RS422, and RS485 Serial Communication 2: RS-232 - Wikipedia 3: RS232 Serial Communication Protocol: Basics, Working & Specifications

Question 115

Which is the PRIMARY reason why Modbus over Ethernet is easy to manaqe in a firewall?
Available Choices (select all choices that are correct)

A.Modbus uses a single master to communicate with multiple slaves usinq simple commands.
B.Modbus is a proprietary protocol that is widely supported by vendors.
C.Modbus uses explicit source and destination IP addresses and a sinqle known TCP port.
D.Modbus has no known security vulnerabilities, so firewall rules are simple to implement.

Correct Answer: C

According to the ISA/IEC 62443-2-4 standard, a training and security awareness program should include all personnel who have access to the industrial automation and control system (IACS) or who are involved in its operation, maintenance, or management. This includes vendors and suppliers, employees, temporary staff, contractors, and visitors. The purpose of the program is to ensure that all personnel are aware of the security risks and policies related to the IACS, and that they have the necessary skills and knowledge to perform their roles in a secure manner. The program should also cover the roles and responsibilities of different personnel, the reporting procedures for security incidents, and the best practices for security hygiene. References:
