💡 Why This Matters

🌍 Real World

Understanding common cybersecurity risks helps individuals and companies protect their data and devices from attacks.

💼 Career

Basic knowledge of cybersecurity risks is important for roles in IT support, office administration, and any job that handles sensitive information.

1

Create the cybersecurity risks dictionary

Create a dictionary called cybersecurity_risks with these exact entries: 'Phishing' with value 'Tricking people to give sensitive info', 'Malware' with value 'Software that harms devices', and 'Data Breach' with value 'Unauthorized access to data'.

Cybersecurity

# Create the cybersecurity_risks dictionary with exact keys and values
# Your code here

Hint

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

2

Add importance explanation

Add a variable called importance and set it to the string 'Cybersecurity protects our information and devices from harm.'

Cybersecurity

cybersecurity_risks = {
    'Phishing': 'Tricking people to give sensitive info',
    'Malware': 'Software that harms devices',
    'Data Breach': 'Unauthorized access to data'
}
# Add the importance variable below
# Your code here

Hint

Use a simple assignment to create the importance variable with the exact text.

3

Loop over the risks dictionary

Use a for loop with variables risk and description to iterate over cybersecurity_risks.items(). Inside the loop, create a new dictionary called risk_summaries that stores each risk as key and its description as value.

Cybersecurity

cybersecurity_risks = {
    'Phishing': 'Tricking people to give sensitive info',
    'Malware': 'Software that harms devices',
    'Data Breach': 'Unauthorized access to data'
}
importance = 'Cybersecurity protects our information and devices from harm.'
# Create risk_summaries dictionary using a for loop
# Your code here

Hint

Start with an empty dictionary risk_summaries = {} and fill it inside the loop.

4

Add final summary combining importance and risks

Add a string variable called summary that starts with the importance text, then adds the phrase ' The main risks are:', and finally lists all the risk names separated by commas from risk_summaries keys.

Cybersecurity

cybersecurity_risks = {
    'Phishing': 'Tricking people to give sensitive info',
    'Malware': 'Software that harms devices',
    'Data Breach': 'Unauthorized access to data'
}
importance = 'Cybersecurity protects our information and devices from harm.'
risk_summaries = {}
for risk, description in cybersecurity_risks.items():
    risk_summaries[risk] = description
# Create summary string combining importance and risk names
# Your code here

Hint

Use ', '.join(risk_summaries.keys()) to list the risk names separated by commas.
