Nmap is a powerful network discovery tool that scans systems for open ports and vulnerabilities.

How to Use:

nmap -sS -p 1-1000 <target_IP>

  • -sS: Stealth scan mode.

  • -p: Specify port range.

2. Metasploit Framework

A robust platform for developing and executing exploit code.

Example:

msfconsole
use exploit/multi/handler
set payload windows/meterpreter/reverse_tcp
set LHOST <your_IP>
set LPORT <port>
exploit

3. Wireshark

A network protocol analyzer used for capturing and inspecting data packets.

Common Use Case:

wireshark

  • Monitor network traffic in real-time.

  • Identify suspicious activities like unauthorized access.

4. Burp Suite

An integrated platform for web application security testing.

Features:

  • Spidering web applications.

  • Identifying vulnerabilities such as SQL injection or XSS.

5. John the Ripper

A fast password cracker designed to detect weak passwords.

Command:

john --wordlist=<path_to_wordlist> <password_file>

Cyber Security Scenarios with Kali Linux

Scenario 1: Identifying Network Vulnerabilities

  • Step 1: Use Nmap to scan the network for open ports.

  • Step 2: Analyze results to identify potential entry points.

  • Step 3: Use Metasploit to exploit discovered vulnerabilities and test system defenses.

Scenario 2: Securing a Wireless Network

  • Step 1: Use Aircrack-ng suite to analyze wireless network security.

  • Step 2: Identify weak encryption protocols like WEP.

  • Step 3: Upgrade to WPA2 or WPA3 for enhanced security.

Scenario 3: Web Application Security Testing

  • Step 1: Use Burp Suite to spider and map the application.

  • Step 2: Identify vulnerabilities such as SQL Injection or Cross-Site Scripting.

  • Step 3: Implement fixes and retest using the same tools.
