I feel like a Rorschach Test.

Is the Nanog confernce network really insecure for its purpose?

Some security experts may claim it is, but I'm not certain they are
correct.  Do you put a biometric reader and armed guard next to a
public drinking fountain?  What is the risk of someone stealing
the water? Its possible, even likely, an unauthorized person will
take a drink but what is the loss versus the cost of more security
for the drinking fountain?

Yes, some security consulting firm issuing press releases about the
dangers of war-chalking, war-driving, war-pr may claim the network is
insecure.  Its great for generating publicity.

The Nanog conference wireless network a semi-public, unauthenticated
network used by several hundred competitors for a few days.  It is about
as secure as the wired network, the hotel in-room cable, cellular
telephones or most other available means of communication at a convention
center. Users can take appropriate measures to secure their communications
based on their risk acceptance.

I don't see much of a need to rely on a volunteer network operator to
provide what I think is the appropriate level of security for my
communications.  Heck, even if Nanog used the latest, greatest network
security whiz-bang gadgets to secure the network; I still wouldn't rely
on it.

Link-layer encryption always sounds like a "simple" security solution.
But when using other people's networks, you are usually better off with a
different security solution.  How many people use modems with encryption
to dial into their local ISP?  How many use link-layer encryption with
their NIC cards on their wired networks?

ICANN had armed guards at its meeting to keep the rif-raff out.  I don't
think NANOG requires that level of security (yet).  We still run the
network cable down the hallways, and "hide" the wireless access points
in the potted palms next to the bar.
