>From my own post to SF some months back with a similar question. These
resources helped me out. The full thread is at the following URL:
http://www.securityfocus.com/archive/101/421146/30/0/threaded
1. "Host Detection - Generating arbitrary responses to identify
inter-networked nodes".
http://www.zone-h.org/files/29/responses-tisc.txt
2. "Techniques to validate host connectivity"
http://packetstorm.linuxsecurity.com/papers/protocols/host-detection.txt
3. "Diggin em Walls - Detection of Firewalls, and Probing networks behind
firewalls".
http://neworder.box.sk/newsread.php?newsid=2914
4. "Host Discovery with Nmap"
http://www.l0t3k.net/biblio/fingerprinting/en/NMAP-mwdiscovery.pdf
Provides different enumeration scenarios (Firewall with Filtering, Firewall
with Generic Ruleset, Firewall with specific rules, Stateful Firewall with
specific rules) and describes how to customize nmap scans for best results
with each scenario. Provides example tcpdump output for each scan.
5. "Strategies for Defeating Distributed Attacks"
http://www.megasecurity.org/Dos/Simple_Nomad.txt
The title is a little misleading. Do a Find for the word "enumeration" and
read from there. Also a very interesting few paragraphs on using non-echo
ICMP messages for host enumeration. See especially the section titled "ICMP
Defense".
6. "Firewall Penetration Testing"
http://www.wittys.com/files/mab/fwpentesting.html
(Borrows heavily from the original Firewalk paper but still worth a read)
7. "Network Scanning Techniques" - Ofir Arkin
http://www.sys-security.com/archive/papers/Network_Scanning_Techniques.p
df
8. "Low Level enumeration with TCP/IP"
http://www.securitydocs.com/library/3012/2
TOOLS
---------
1. Mike Shiffman/David Goldsmith's Firewalk paper
http://www.packetfactory.net/projects/firewalk/firewalk-final.pdf
2. "Tcptraceroute examples"
http://michael.toren.net/code/tcptraceroute/examples.txt
3. "Paratrace Analysis and Defence" (SANS GIAC practical)
http://www.giac.org/certified_professionals/practicals/gcih/0392.php
Sincerely.
David Ball.
