Build A Darknet To Capture Naughty Traffic
DM_NeoFLeX writes "Have some routable Address Space lying around? You might want to build a DarkNet. The folks over at Team Cymru have outlined instructions for creating one with FreeBSD and as little as /32 routable space. From the article: 'A Darknet is a portion of routed, allocated IP space in which no active services or servers reside. These are 'dark' because there is, seemingly, nothing within these networks. Any packet that enters a Darknet is by its presence Aberrant.' Darknets can provide useful information for tracking the flow of naughty network traffic."
These are 'dark' because there is, seemingly, nothing within these networks. Any packet that enters a Darknet is by its presence Aberrant.
That's like the mailman trying to deliver letters to Santa Claus, or somebody addressing a letter wrong, thank good I know all those letters are Abberant now.
Your hair look like poop, Bob! - Wanker.
Ok, it's a really good idea, but catching the naughty traffic isnt the hard part, what does it do witht he naughty traffic it gets, just make a pretty graph?

Sounds like a standard HoneyPot, except the only machine on the nextwork segement is a packet sniffer, so the address doesn't have any real destinations.. Not a big deal. I'm sure the honeynet people have done similar.

Using your sig line to advertise for friends is lame.
An interesting use of a darknet would be to shield a real server from unwanted attacks. Have the darknet relate any internet IPs that contact the darknet to your real server to ignore.
As an example. Setup a darknet on the following IPs:
DARK_A : 204.210.34.1
DARK_B : 204.210.34.3
Setup the real server mathematically between the two darknet IP addresses:
REAL : 204.210.34.2
Now have DARK_A & DARK_B contact REAL whenever DARK_A or DARK_B receive any packets. REAL can be setup to, on the fly, filter out any packets received from the same source as the DARK servers reported.
In a sense you're creating a realtime blacklist. You can set the list on a timed delay to expire. Or even filter out specific packet signatures instead of entire suspect IP addresses.
just a thought...

I have a whole list of bookmarks for my naughty traffic.
Seriously, though... I have a spare wireless router set up at work that's easily hacked, easily found, and logs every damn thing that touches it. Our real wireless network is obscured, encrypted, mac filtered, etc. I realize it's not technically the same thing as the post describes (I guess you'd call it a honeypot network or something) but it's the same idea.
Of course, nobody will care if a hacker makes his way into our network (honeypot or not) unless he does some "damage."
Seems the purpose is to monitor IP scanning activity - something wholly impractical with IPv6.
sic transit gloria mundi
actually a darknet would be a peer to peer group where the users know most if not all other members, such as a Dormitory floor setting up FTP servers and giving accounts to everyone on the floor (not that i have any involvement in that sort of activity)
You sound like my roommate, anything He hasn't heard of isn't legitimate or good enough, which is funny since he won't even accept as valid terms that are listed in the Jargon File)
