With Microsoft's Wi-Fi Sense, people connect to open Wi-Fi networks. But does simplifying the connection process increase the peril? Some security experts think so.The big security concern
Lee Munson in the Sophos Naked Security blog writes, "What we do know is that access to your network can, depending on your choices, be shared between all your contacts on Outlook.com, Skype and/or Facebook. So, you could be inadvertently granting access network to people you don't know all that well."
Munson's concern is valid, especially if users do not fully understand how Wi-Fi Sense works. He adds, "That means you could find yourself in the position where a comparative stranger who has a tenuous link to you — say, the man you emailed about painting your kitchen, your Zumba instructor or your babysitter — could lurk near your home and connect to your wireless network using the access rights you inadvertently gave them."
