Intrusion Prevention Systems (IPS) in Cybersecurity - Mini Project: Build & Apply

Understanding Intrusion Prevention Systems (IPS)

📖 Scenario: You are working in a small company's IT security team. Your manager wants you to understand how Intrusion Prevention Systems (IPS) work to protect the company's network from attacks.

🎯 Goal: Build a simple step-by-step explanation of how an Intrusion Prevention System (IPS) functions, including its data setup, configuration, core logic, and final deployment concept.

📋 What You'll Learn

Create a list of common network threats

Define a threshold for alerting on suspicious activity

Write a simple logic to detect threats based on the threshold

Add a final step to describe how the IPS blocks threats

💡 Why This Matters

🌍 Real World

Intrusion Prevention Systems are used in real networks to automatically detect and stop cyber attacks before they cause harm.

💼 Career

Understanding IPS basics is important for cybersecurity roles such as network security analyst, security engineer, and IT administrator.

1

Data Setup: List common network threats

Create a list called network_threats containing these exact strings: 'Malware', 'Phishing', 'DDoS', 'SQL Injection', and 'Man-in-the-Middle'.

Cybersecurity

# Create the list network_threats with the specified threats
# Your code here

Need a hint?

Use square brackets [] to create a list and include all threat names as strings.

2

Configuration: Set alert threshold

Create a variable called alert_threshold and set it to the integer 3. This will represent the minimum number of detected threats to trigger an alert.

Cybersecurity

network_threats = ['Malware', 'Phishing', 'DDoS', 'SQL Injection', 'Man-in-the-Middle']
# Set alert_threshold to 3
# Your code here

Need a hint?

Simply assign the number 3 to the variable alert_threshold.

3

Core Logic: Detect threats exceeding threshold

Create a variable called detected_threats and set it to the integer 4. Then create a boolean variable called alert_triggered that is True if detected_threats is greater than or equal to alert_threshold, otherwise False.

Cybersecurity

network_threats = ['Malware', 'Phishing', 'DDoS', 'SQL Injection', 'Man-in-the-Middle']
alert_threshold = 3
# Set detected_threats to 4
# Set alert_triggered based on comparison with alert_threshold
# Your code here

Need a hint?

Use a comparison operator >= to set alert_triggered as True or False.

4

Completion: Describe IPS blocking action

Create a string variable called ips_action and set it to the exact text 'Block suspicious traffic and alert security team' to describe the final action of the IPS.

Cybersecurity

network_threats = ['Malware', 'Phishing', 'DDoS', 'SQL Injection', 'Man-in-the-Middle']
alert_threshold = 3
detected_threats = 4
alert_triggered = detected_threats >= alert_threshold
# Set ips_action to describe the IPS blocking behavior
# Your code here

Need a hint?

Assign the exact phrase describing the IPS action to the variable ips_action.
