How about the fact that it's good to know what hackers use, and what it will look like from a networking standpoint, combined with the fact that almost all good hackers use nmap?

[mailto:agfoust () tva gov] Sent: Friday, September 17, 1999 8:57 AM To: nmap-hackers () insecure org Subject: Examples of legit nmap usage? nmap has the potential of becoming an extremely useful tool for me in my job (not in the hacker sense, but in the discovery and security sense). I ran it for a while and built up a picture of our intranet WAN (with the help of a custom bit of perl and CGI programming), but now I'm being told knock it off for good based on the high amount of messages that began to accumulate in our router logs. All of our other $$$ commercial network tools have so far provided a rather piecemeal view of things, and I would like to continue to use this excellent nmap tool to augment our picture of things (particularly having an inventory of TCP services). Can anyone help me out with a good "business case" for administratively running nmap in a corporate environment? What would be the impact to routers and hosts of say automating a weekly scan on a rather large network (I won't give specifics, but I will say that if I seed nmap with a list of ping-able IP addresses it requires a couple of days to complete a single sweep)? Is using nmap in this fashion a dumb idea? Any good examples of nmap being used for network discovery in any corporations out there? Any information you can provide would be of great use. Thanks.
