you can find the slides for the DC24 NOC review.

Thanks everyone and see y'all at DEF CON 25!

effffn and DEF CON would like to thank the hard work of the NOC team,
not only for the long demanding week in hot Las Vegas but also the
months of planning prior to the con.

There is quite a bit of preparation in every single aspect you can
imagine on how to get all the network and internet requests to all of
the vendors, speakers, press, contests, attendees and also those
convenient DC TV channels for that late morning hangover cure in the
convenience of your hotel room.

It has been said before, and we will say it again: mac, videoman,
#sparky, booger, naifx, arh@wk, nocit, CRV, c0mmiebstrd, serif and
c7five dedicated a great portion of their DEF CON experience to making
sure everything breaks (and if it does, to fix it). So, yeah If you
run into any of them, please make sure you buy them a beverage, that
would be great, mmmk.

AND, the NOC team would like to thank the Caesar’s IT and Encore for
the tireless support in making it all happen.

It looks like DC TV is stable now after the changes and tuning we have made.

We made some changes in the setup and we are closely monitoring the streams that
just started a few minutes ago.

Tweaks will be made on a per-channel basis and hopefully we will have good news

We are aware DCTV is having intermittent issues and we are currently working on

In response to the article that was posted by the Register,
the DEF CON Network Operations Center Team (NOC) pride ourselves on making a
network that allows the community to get Internet access, and have access to
internal resources (Servers, etc.). The DEF CON NOC believes in privacy and
anonymity for our attendees.

When users attach to the DefCon Secure (802.1x/PEAP) network, we have made the
decision to do our best to make that data/traffic inaccessible, and the team
does not allow for data monitoring, nor recording of the traffic. We do have
overall bandwidth monitoring- but will never run driftnet, ntop or other tools
that invade the privacy of the users on the secure network.

The DEF CON network resources, and staff who volunteer in the NOC at DEF CON
currently do not have any part in the operations of the Black Hat network(s).
The DEF CON NOC also doesn’t allow vendors to use the network as a place to demo
or experiment with our user’s traffic.

Now… If you happen to attach to any network that does not have the more secure
certificate authentication method enabled – all bets are off. Your traffic will
be monitored – not by us, but by the people around you. We also ship the open
WiFi network traffic off to the Wall of Sheep as well, and anyone on the
unsecure network can and will easily Man-In-The-Middle your traffic.

If you want to get on the “DefCon” Secure network- follow the instructions that
are posted on Each PEAP session that is created
from the client to the controller is a unique session, and is not allowed to
talk to any of the other users on the network once connected to the official

If you are concerned about someone capturing your credentials, you don’t want to
register ad userid, or want to maintain anonymity we have also setup a common
username and password of defcon/defcon. So if someone says that they captured
your credentials, it’s really not that big of a deal, especially when everyone
has a unique session.

You should still install and only trust the certificates that we have posted on

Sine Qua Non


We are happy to be here and everything should be up and running at this point in
both Paris and Bally's conference centers.

Also, don't forget to check DC TV in the convenience of your hotel room.
