I hope you don't think this is too far off topic.
I'm looking for a script or program that will do the following:
1. Extract UNIX syslog by source ip address.
2. Do a nslookup.
3. Do a "whois x.x.x.x () whois arin net Do further queries to
apnic.net or ripe.net if necessary.
4. Traceroute source ip address
5. Using the whois, traceroute and nslookup information list email
addresses. Plus abuse () domains etc.
6. Merge all the information into a nice neat file to be mailed.
If someone does not already have something like this I'll write it.
With the "serious" scans/attempts I do this manually. Note this example
is a "strong" access list on a Cisco router logged to syslog
http://www.pasadena.net/cisco/secure.html
Here is a sample of what I normally send out:
-----------------------------------
To: abuse () domain, userINwhois () domain, security () domain

I agree with you fully on this. I've done quite a few
firewalls. I set these
up for automated intrusion detection, listening on specific
ports, such as
imap, pop3, zone transfers, http, etc. If your interested,
