Cybersecurity Lab – Threats, Defenses & Network Security

Cybersecurity is the discipline of protecting computers, networks, and data from unauthorized access, damage, or attack. Unlike cryptography (which designs protective algorithms) or cryptanalysis (which breaks them), cybersecurity deals with the full operational stack: threat modeling, secure system configuration, intrusion detection, and incident response. This lab lets you probe simulated networks for vulnerabilities, configure firewall rules, and observe how defenders and attackers interact in real time.

What you can do in this simulation

Simulate common attack vectors—port scanning, brute force, phishing—and observe system responses
Configure firewall rules and watch which packets are allowed or blocked
Inspect simulated network traffic to identify suspicious patterns
Test password strength against dictionary and brute-force attack simulations
Walk through a simplified incident-response workflow after a detected intrusion

Concepts covered

cybersecurity · network security · firewall · intrusion detection · threat modeling · vulnerability assessment
