I'd argue with you on that one. It appears to me this rule can trigger on
any form of administrator-level network access - something that happens all
the time from anywhere IMHO... And our network won't be unusual in that
regard (it's like triggering on root-access via SSH)
Snort probably couldn't handle the sizing of a var definition containing all
the IP addresses on our WAN that could have valid reasons to do this action
- no - wait - HOME_NET would do it...
I think I'll just disable it :-)
