Why security protects deployed IoT devices in Raspberry Pi - See It in Action

Why Security Protects Deployed IoT Devices

📖 Scenario: You have a small Raspberry Pi device connected to sensors in your home. This device collects data like temperature and humidity. You want to make sure only trusted users can access this data and that the device is safe from hackers.

🎯 Goal: Build a simple program that stores sensor data securely and only shows data if the correct password is given. This teaches why security is important for devices like Raspberry Pi in real life.

📋 What You'll Learn

Create a dictionary called sensor_data with exact keys 'temperature' and 'humidity' and their values

Create a variable called password with the exact value 'secure123'

Write a function called check_access that takes a password and returns True if it matches password, else False

Print the sensor data only if the password is correct, otherwise print 'Access denied'

💡 Why This Matters

🌍 Real World

IoT devices like Raspberry Pi collect important data that should only be accessed by trusted users to prevent misuse or hacking.

💼 Career

Understanding basic security helps in roles like IoT developer, system administrator, or cybersecurity specialist to protect devices and data.

1

Create sensor data dictionary

Create a dictionary called sensor_data with these exact entries: 'temperature': 22.5 and 'humidity': 45

Raspberry Pi

# Create the sensor_data dictionary with temperature and humidity
# Your code here

Need a hint?

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

2

Set the password variable

Create a variable called password and set it to the exact string 'secure123'

Raspberry Pi

sensor_data = {'temperature': 22.5, 'humidity': 45}
# Create the password variable with value 'secure123'
# Your code here

Need a hint?

Use an equals sign = to assign the string to the variable.

3

Write the access check function

Write a function called check_access that takes one parameter input_password and returns True if input_password equals password, otherwise returns False

Raspberry Pi

sensor_data = {'temperature': 22.5, 'humidity': 45}
password = 'secure123'
# Define the check_access function below
# Your code here

Need a hint?

Use def to define the function and compare the input to the stored password.

4

Print sensor data if password is correct

Write code to ask the user for a password using input(). Use check_access to verify it. If correct, print sensor_data. Otherwise, print 'Access denied'

Raspberry Pi

sensor_data = {'temperature': 22.5, 'humidity': 45}
password = 'secure123'

def check_access(input_password):
    return input_password == password

# Ask for password and print sensor_data if access allowed
# Your code here

Need a hint?

Use input() to get user input and an if statement to check access.
