Autodesk Actrix 2000 does a nice job on helping you draw network maps as
well as others. It has lots of cool features and lots of network equipment
one needs in order to present a nice looking network map. You can see some
samples on their site at:

Actually Visio 2k is very cool in drawing very detailed network maps, and
if you have the 99.3 Network Equipment CD, a majority of the vendors have
provided very detailed icons for almost any network diagram.

One can spend hours putting these type of diagrams together.  The cool
thing is when you print on a plotter, they come out very nice.

The one caveat, if you print on a E size plotter, minor line weirdness can
cause some problems

Mapping the network, and making a network map require seperate tools.

Mapping is best done with nessus, firewalk, ping, traceroute, and
the route servers for network and transport layer.  tcpdump, arp and
anti-sniff for ethernet/link layer. Nmap is fine for session. Application,
well, that's brute forcers, skriptz, whisker, and good old fashioned
kung-f00 with some genuine clue thrown in for good measure.

Some of the commercial tools do mapping AFAIK, and are useful for comparing
your results to, but pointing tkined, visio 2k, or cheops at a network
probably won't give you a thorough picture. If you wouldn't bill your
clients for cookie cutter cybercop/iss/retina/nmap/nessus reports, why
would you bill them for the same from a network mapping package?

Making a network map; White board, and visio has cute widgets.

Each layer of the protocol stack is a map unto itself. Tool based
methodologies have the inherant problem of a top down approach.
They enumerate services and their associated vulnerabilities and
then induce that by there being a service and vuln, there must be a
host, which implies a network, and vaguely suggests an underlying

Seems logical right? It is, but it's still wrong. It's consistant
with an inductive method, it's true within the scope of what is required
for a network to exist, but it's totally incomplete.
