Mobile SCADA access in SCADA systems - Mini Project: Build & Apply

Mobile SCADA Access Setup

📖 Scenario: You work for a company that manages industrial machines using a SCADA system. The company wants to allow engineers to check machine status from their mobile phones securely and easily.

🎯 Goal: Build a simple configuration to enable mobile access to the SCADA system with basic security settings.

📋 What You'll Learn

Create a dictionary with SCADA device IPs and their names

Add a configuration variable for allowed mobile IP range

Filter devices accessible from the allowed mobile IP range

Print the list of accessible devices for mobile users

💡 Why This Matters

🌍 Real World

Industrial companies use SCADA systems to monitor and control machines remotely. Allowing mobile access helps engineers check system status on the go.

💼 Career

DevOps and system administrators often configure secure remote access to critical systems like SCADA for mobile users.

1

Create SCADA devices dictionary

Create a dictionary called scada_devices with these exact entries: '192.168.1.10': 'Pump Controller', '192.168.1.11': 'Valve Controller', '192.168.2.20': 'Temperature Sensor', '192.168.2.21': 'Pressure Sensor'.

SCADA systems

# Create the scada_devices dictionary with IPs and device names
# Your code here

Need a hint?

Use a Python dictionary with IP addresses as keys and device names as values.

2

Add allowed mobile IP range

Add a variable called allowed_mobile_ip_prefix and set it to the string '192.168.1.' to represent the allowed mobile IP range prefix.

SCADA systems

scada_devices = {
    '192.168.1.10': 'Pump Controller',
    '192.168.1.11': 'Valve Controller',
    '192.168.2.20': 'Temperature Sensor',
    '192.168.2.21': 'Pressure Sensor'
}
# Add allowed_mobile_ip_prefix variable below
# Your code here

Need a hint?

Use a string variable to hold the IP prefix for allowed mobile devices.

3

Filter accessible devices for mobile

Create a dictionary called mobile_access_devices that includes only devices from scada_devices whose IP starts with allowed_mobile_ip_prefix. Use a dictionary comprehension with ip and name as variables.

SCADA systems

scada_devices = {
    '192.168.1.10': 'Pump Controller',
    '192.168.1.11': 'Valve Controller',
    '192.168.2.20': 'Temperature Sensor',
    '192.168.2.21': 'Pressure Sensor'
}

allowed_mobile_ip_prefix = '192.168.1.'

# Create mobile_access_devices dictionary using dictionary comprehension
# Your code here

Need a hint?

Use ip.startswith(allowed_mobile_ip_prefix) inside the dictionary comprehension.

4

Display accessible devices for mobile users

Write a print statement to display the mobile_access_devices dictionary.

SCADA systems

scada_devices = {
    '192.168.1.10': 'Pump Controller',
    '192.168.1.11': 'Valve Controller',
    '192.168.2.20': 'Temperature Sensor',
    '192.168.2.21': 'Pressure Sensor'
}

allowed_mobile_ip_prefix = '192.168.1.'

mobile_access_devices = {ip: name for ip, name in scada_devices.items() if ip.startswith(allowed_mobile_ip_prefix)}

# Print the mobile_access_devices dictionary
# Your code here

Need a hint?

Use print(mobile_access_devices) to show the filtered devices.
