Why proactive scanning finds weaknesses in Cybersecurity - See It in Action

Why Proactive Scanning Finds Weaknesses

📖 Scenario: You work in a cybersecurity team that wants to find weak points in a company's computer system before hackers do.To do this, you use a method called proactive scanning, which checks the system regularly to spot problems early.

🎯 Goal: Build a simple Python program that lists system parts, sets a scanning threshold, checks each part for weaknesses, and marks the weak parts found by proactive scanning.

📋 What You'll Learn

Create a dictionary called system_parts with these exact entries: 'Firewall': 85, 'Antivirus': 90, 'Web Server': 70, 'Database': 65, 'Email Server': 75

Create a variable called scan_threshold and set it to 75

Use dictionary comprehension with variables part and security_score to iterate over system_parts.items() and create a dictionary called weaknesses_found that includes only parts with scores less than scan_threshold

Add a final line that sets a variable called scan_complete to True to show the scan finished

💡 Why This Matters

🌍 Real World

Proactive scanning is used by cybersecurity teams to find and fix weaknesses before attackers exploit them.

💼 Career

Understanding how to identify weak points in systems is key for roles like security analyst, penetration tester, and IT auditor.

1

Create the system parts dictionary

Create a dictionary called system_parts with these exact entries: 'Firewall': 85, 'Antivirus': 90, 'Web Server': 70, 'Database': 65, 'Email Server': 75

Cybersecurity

# Create the system_parts 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 scanning threshold

Create a variable called scan_threshold and set it to 75

Cybersecurity

system_parts = {
    'Firewall': 85,
    'Antivirus': 90,
    'Web Server': 70,
    'Database': 65,
    'Email Server': 75
}
# Create scan_threshold variable and set it to 75
# Your code here

Need a hint?

Just assign the number 75 to the variable named scan_threshold.

3

Find weaknesses with a loop and dictionary comprehension

Use dictionary comprehension with variables part and security_score to iterate over system_parts.items() and create a dictionary called weaknesses_found that includes only parts with scores less than scan_threshold

Cybersecurity

system_parts = {
    'Firewall': 85,
    'Antivirus': 90,
    'Web Server': 70,
    'Database': 65,
    'Email Server': 75
}
scan_threshold = 75
# Create weaknesses_found dictionary with parts scoring less than scan_threshold
# Your code here

Need a hint?

Use dictionary comprehension with for part, security_score in system_parts.items() and an if condition to filter.

4

Mark the scan as complete

Add a final line that sets a variable called scan_complete to True to show the scan finished

Cybersecurity

system_parts = {
    'Firewall': 85,
    'Antivirus': 90,
    'Web Server': 70,
    'Database': 65,
    'Email Server': 75
}
scan_threshold = 75
weaknesses_found = {part: security_score for part, security_score in system_parts.items() if security_score < scan_threshold}
# Set scan_complete to True
# Your code here

Need a hint?

Just assign True to the variable scan_complete.
