I'm waiting for one of the professional security consulting firms to issue
their weekly press release screaming "Network Operator Meeting Fails
Security Test."

The wireless networks at NANOG meetings never follow what the security
professionals say are mandatory, essential security practices. The NANOG
wireless network doesn't use any authentication, enables broadcast SSID,
has a trivial to guess SSID, doesn't use WEP, doesn't have any perimeter
firewalls, etc, etc, etc. At the last NANOG meeting IIRC over 400
stations were active on the network.

Are network operators really that clueless about security, or perhaps we
need to step back and re-think.  What are we really trying to protect?

Banks are mostly concerned about people defrauding the bank, not the
bank's customers.  Banks rarely check the signature on a check.  Is
security just perception?
