Re: portable honeyport tool waiting for a name

Also, keep in mind there is a difference between Low Interaction Honeypots
and High Interaction Honeypots.

If you are going to go with Honeypots as part of your security posture, go
with something that is limited and easy to deploy.

If you are researching how attacks work go with High Interaction
Honeypots....  Or go to your uncles house and remove the malware that got
their due to his massive porn habit.  Whichever works for you.
