Why SCADA security is critical in SCADA systems - See It in Action

Why SCADA Security Is Critical

📖 Scenario: You work as a technician responsible for monitoring a SCADA system that controls water treatment plants. Your manager wants you to understand why securing this system is very important to keep the water safe and the plant running smoothly.

🎯 Goal: Build a simple program that lists common SCADA system components, sets a security risk level, identifies critical components based on that risk, and then prints out the critical components that need protection.

📋 What You'll Learn

Create a dictionary called scada_components with these exact entries: 'RTU': 'Remote Terminal Unit', 'PLC': 'Programmable Logic Controller', 'HMI': 'Human Machine Interface', 'SCADA Server': 'Central Control Server'

Create a variable called security_risk_level and set it to 7

Use a dictionary comprehension called critical_components to select components from scada_components where the key is either 'PLC' or 'SCADA Server' if security_risk_level is greater than 5

Print the critical_components dictionary

💡 Why This Matters

🌍 Real World

SCADA systems control important infrastructure like water plants, power grids, and factories. Protecting these systems prevents accidents and keeps services running safely.

💼 Career

Understanding SCADA security basics helps technicians and engineers keep industrial systems safe from cyber attacks and failures.

1

Create SCADA system components dictionary

Create a dictionary called scada_components with these exact entries: 'RTU': 'Remote Terminal Unit', 'PLC': 'Programmable Logic Controller', 'HMI': 'Human Machine Interface', 'SCADA Server': 'Central Control Server'

SCADA systems

# Create the scada_components dictionary with exact entries
# Your code here

Need a hint?

Use curly braces {} to create a dictionary with the exact keys and values given.

2

Set the security risk level

Create a variable called security_risk_level and set it to 7

SCADA systems

scada_components = {
    'RTU': 'Remote Terminal Unit',
    'PLC': 'Programmable Logic Controller',
    'HMI': 'Human Machine Interface',
    'SCADA Server': 'Central Control Server'
}
# Set security_risk_level to 7
# Your code here

Need a hint?

Assign the number 7 to the variable named security_risk_level.

3

Select critical components based on risk

Use a dictionary comprehension called critical_components to select components from scada_components where the key is either 'PLC' or 'SCADA Server' only if security_risk_level is greater than 5

SCADA systems

scada_components = {
    'RTU': 'Remote Terminal Unit',
    'PLC': 'Programmable Logic Controller',
    'HMI': 'Human Machine Interface',
    'SCADA Server': 'Central Control Server'
}
security_risk_level = 7
# Create critical_components dictionary using comprehension
# Your code here

Need a hint?

Use a dictionary comprehension with for k, v in scada_components.items() and an if condition checking security_risk_level > 5 and key in the list ['PLC', 'SCADA Server'].

4

Print the critical components

Write a print statement to display the critical_components dictionary

SCADA systems

scada_components = {
    'RTU': 'Remote Terminal Unit',
    'PLC': 'Programmable Logic Controller',
    'HMI': 'Human Machine Interface',
    'SCADA Server': 'Central Control Server'
}
security_risk_level = 7
critical_components = {k: v for k, v in scada_components.items() if security_risk_level > 5 and k in ['PLC', 'SCADA Server']}
# Print the critical_components dictionary
# Your code here

Need a hint?

Use print(critical_components) to show the filtered dictionary.
