We’ve often heard security folks explain their belief that one of the best ways to protect Web privacy and security on one's home turf is to lock down one's private Wi-Fi network with a strong password. But a coalition of advocacy organizations is calling such conventional wisdom into question.

Members of the “Open Wireless Movement,” including the Electronic Frontier Foundation (EFF), Free Press, Mozilla, and Fight for the Future are advocating that we open up our Wi-Fi private networks (or at least a small slice of our available bandwidth) to strangers. They claim that such a random act of kindness can actually make us safer online while simultaneously facilitating a better allocation of finite broadband resources.

The OpenWireless.org website explains the group’s initiative. “We are aiming to build technologies that would make it easy for Internet subscribers to portion off their wireless networks for guests and the public while maintaining security, protecting privacy, and preserving quality of access," its mission statement reads. "And we are working to debunk myths (and confront truths) about open wireless while creating technologies and legal precedent to ensure it is safe, private, and legal to open your network.”

One such technology, which EFF plans to unveil at the Hackers on Planet Earth (HOPE X) conference next month, is open-sourced router firmware called Open Wireless Router. This firmware would enable individuals to share a portion of their Wi-Fi networks with anyone nearby, password-free, as Adi Kamdar, an EFF activist, told Ars on Friday.

Home network sharing tools are not new, and the EFF has been touting the benefits of open-sourcing Web connections for years, but Kamdar believes this new tool marks the second phase in the open wireless initiative. Unlike previous tools, he claims, EFF’s software will be free for all, will not require any sort of registration, and will actually make surfing the Web safer and more efficient.

Open Wi-Fi initiative members have argued that the act of providing wireless networks to others is a form of “basic politeness… like providing heat and electricity, or a hot cup of tea” to a neighbor, as security expert Bruce Schneier described it.

Walled off

Kamdar said that the new firmware utilizes smart technologies that prioritize the network owner's traffic over others', so good samaritans won't have to wait for Netflix to load because of strangers using their home networks. What's more, he said, "every connection is walled off from all other connections," so as to decrease the risk of unwanted snooping.

Additionally, EFF hopes that opening one’s Wi-Fi network will, in the long run, make it more difficult to tie an IP address to an individual.

“From a legal perspective, we have been trying to tackle this idea that law enforcement and certain bad plaintiffs have been pushing, that your IP address is tied to your identity. Your identity is not your IP address. You shouldn't be targeted by a copyright troll just because they know your IP address," said Kamdar.

This isn’t an abstract problem, either. Consider the case of the Californian who, after allowing a friend access to his home Wi-Fi network, found his home turned inside-out by police officers asking tough questions about child pornography. The man later learned that his houseguest had downloaded illicit materials, thus subjecting the homeowner to police interrogation. Should a critical mass begin to open private networks to strangers, the practice of correlating individuals with IP addresses would prove increasingly difficult and therefore might be reduced.

While the EFF firmware will initially be compatible with only one specific router, the organization would like to eventually make it compatible with other routers and even, perhaps, develop its own router. “We noticed that router software, in general, is pretty insecure and inefficient," Kamdar said. “There are a few major players in the router space. Even though various flaws have been exposed, there have not been many fixes.”
