What does SCADA stand for in the context of industrial machinery control systems?

• Supervisory Control and Data Acquisition

• System Control and Data Analysis

• Supervisory Command and Device Automation

• System Configuration and Diagnostic Assistance

Which of the following best describes the function of SCADA systems?

• SCADA systems control machinery without the need for any communication links

• SCADA systems are used exclusively for wireless communication in industrial environments

• SCADA systems are designed to project, monitor, and automate industrial operations through Ethernet-based two-way communication

• SCADA systems only provide data analysis for industrial machinery

Which of the following statements about SCADA systems is true?

• Real-time data is only collected from end-user computers

• Historical data is irrelevant to optimizing plant operations

• Data is processed solely by Human-Machine Interfaces (HMIs)

• SCADA software logs data for historical analysis and record-keeping

Why do SCADA systems remain vulnerable to cyberattacks despite the addition of firewall protections?

• They only operate in isolated environments

• They use outdated hardware

• They do not collect real-time data

• They are integrated with modern communication networks, creating more entry points for attacks

What potential solution is being considered to enhance the security of SCADA systems against cyber-attacks?

• Increased manual monitoring

• Using only firewalls

• Deep learning technologie

• Isolating SCADA systems from all networks

How can the specifications and model numbers of connected devices to a SCADA network be determined?

• By analyzing the firewall logs

• By tracking the Modbus slave identification of the targeted SCADA system

• By monitoring network traffic patterns

• By reviewing user access logs

What is the correct sequence of steps attackers follow during an address scanning attack on a SCADA system?

• Scanning → Device Identification → Search for vulnerabilities → Performing attacks

• Scanning → Performing attacks → Search for vulnerabilities → Device Identification

• Scanning → Search for vulnerabilities → Device Identification → Performing attacks

• Device Identification → Scanning → Performing attacks → Search for vulnerabilities

What occurs concurrently with the generation of targeted nodes at different temporal frequencies?

• The network bandwidth is increased

• All network devices are rebooted

• The firewall is completely turned off

• The TCP connection is partially disabled

What dual purpose does port scanning serve in network security?

• It only helps to identify network traffic issues

• It can strengthen defenses while also being used maliciously

• It is used solely for monitoring bandwidth usage

• It is ineffective in detecting open ports

What is the primary focus of the study conducted by Jmila & Houda (2022)?

• The performance of deep learning classifiers in network intrusion detection

• The resistance of shallow classifiers to adversarial attacks

• The effectiveness of firewalls in protecting networks

• The application of deep learning in data augmentation
