Network Discovery Midterm Overview & Challenges in IP Management and Security

This document outlines the key components of a network discovery midterm project led by Dr. Mark Stamp and CS Technician Kevin Ross. It details the setup of a Linksys WRT54G WAP and a Mini-ITX PC, including network configurations, open ports, and the running services. The project faced challenges such as firewall scanning difficulties and DHCP conflicts that impacted static IP assignments. Tools like nmap and nessus were utilized for analysis. The document also addresses issues with equipment failure and includes considerations for data security.

  1. Network Discovery Midterm • Instructor: Dr. Mark Stamp • CS Technician: Kevin Ross • Equipment: • Linksys WRT54G WAP • Via Mini-ITX PC • Cords, powerstrip, etc.

  2. WAP SSID: jasmine WEP Key: c0ffee2020 IP: 192.168.20.1 Running DD-WRT firmware Gives out IP addresses in range: 192.168.20.100-150

  3. WAP • Open Ports: • Port: Service: • 22 ssh (secure shell access) • 53 dns (ipmasq) • 80 http (config tool)

  4. Firewall Ports open (forwarded to static IP 192.168.20.120): 23 8080

  5. Networked computer Hostname: bob-desktop IP Address: 192.168.20.120 Running Ubuntu 7.10 Form factor: mini-itx Hardware condition: deceased

  6. Networked computer Open ports: Port Service 23 SSH (OpenSSH) 8080 HTTP (lighttpd web server)

  7. Bob-desktop port 8080: Web root folder images music stuff

  8. Web root folder index.html links to other directories robots.txt excludes directory: stuff

  9. images index.html

  10. music index.html

  11. stuff index.html info.txt.bfa

  12. info.txt.bfa • blowfish encrypted file • Internet search: “.bfa extension” • Many command line programs will decrypt

  13. info.txt.bfa • Password: frequently mentioned word from web pages • Contents: bob’s password, among others

  14. Tools: • nmap, nmapfe, nessus • wget, or remember to check for robots.txt and use web browser

  15. Problems: • Firewall scan difficult because all laptops were 1 hop from WAP—needed IP of internal machine or to perform scan one team at a time. • WAP DHCP server temporarily assigned what was supposed to be the static IP of internal machine, 192.168.20.120, to a user’s laptop. • Via hardware died a premature death.
