Some of the security problems with Wi-Fi are well known and there isn't a security consultant worth the paranoia they sell who can't spout their list of the dumbest retail Wi-Fi deployments. There is a small ray of hope. Although Wi-Fi is often quite insecure, the newest Wi-Fi offerings today are a tad bit better. If we can assume that many of the new deployments will be using somewhat more robust approaches, it might be a somewhat smaller catastrophe. Remember that a Wi-Fi mobile disaster doesn't have to be a security breach. Given how easy it is for a children's toy or a wireless microphone to disrupt Wi-Fi and potentially halt mobile payments or, even worse, cause double billings, even a data-secure network could cause mobile nightmares. Ahhh, the joys of Wi-Fi.
Quick-and-Dirty (And Dangerous) Wi-Fi Retail Deployments Likely To Be Rampant In 2012
As mobile trials of all kinds kick into highgear next year, there's almost certainly going to be a trend that will signal very bad security news: a soaring number of retail Wi-Fi trials, many of which will likely be quick-and-dirty efforts to be able to support customers who want to use mobile in-store. Wi-Fi security is bad enough as is, let alone what will happen with lot of slapdash rollouts.
