   • Which group most benefits from learning with Kali Linux in an ethical training environment?
2. Explain how Kali Linux can be used as an educational tool for students to understand hacker techniques.
   • Why is it important to learn offensive techniques in order to defend systems?
3. Identify and describe three Kali Linux tools that illustrate both offensive and defensive learning:
   • Nmap offensive: scanning networks for open ports; defensive: teaching students how to detect and close vulnerabilities.
   • Metasploit offensive: exploiting known vulnerabilities; defensive: testing patches and IDS/IPS systems.
   • Wireshark offensive: capturing network packets; defensive: analyzing traffic for intrusion detection.
4. For one of the tools you find, give one classroom application where you have use this (e.g., scanning a test network, simulating an exploit in a lab, analyzing captured packets).

Deliverables

• A 3 page research paper (double-spaced, 12 pt font).
