ComputerWorld publicizes security problems in airport/airlines use of Wi-Fi: a superb report details some of the recent exposures of holes in the airports and airlines use of Wi-Fi. The challenged institutions claim that even if hackers (in some cases, people who obviously just select an SSID) get on the network, data is still secure. Maybe. Getting on the network is a good first step in getting to applications: it allows iterative probing and buffer overflow attempts.
Meanwhile, this morning I spent a highly entertaining and informative two and a half hours talking with two Swedish gents from Homerun's business development unit about Telia's deployment of public space Wi-Fi. With over 300 hot spots and services reaching into Denmark, Norway, and soon Finland, Homerun is generating real-world experience in how users deal with high-speed data on the road. More on this as I have a chance to distill our conversation.
