EFF: “We’ve asked the companies in our Who Has Your Back Program what they are doing to bolster encryption in light of the NSA’s unlawful surveillance of your communications. We’re pleased to see that four companies—Dropbox, Google, SpiderOak and Sonic.net—are implementing five out of five of our best practices for encryption. In addition, we appreciate that Yahoo! just announced several measures it plans to take to increase encryption, including the very critical encryption of data center links, and that Twitter has confirmed that it has encryption of data center links in progress. See the infographic.

By adopting these practices, described below, these service providers have taken a critical step towards protecting their users from warrantless seizure of their information off of fiber-optic cables. By enabling encryption across their networks, service providers can make backdoor surveillance more challenging, requiring the government to go to courts and use legal process. While Lavabit’s travails have shown how difficult that can be for service providers, at least there was the opportunity to fight back in court.

While not every company in our survey has implemented every recommendation, each step taken helps, and we appreciate those who have worked to strengthen their security. We hope that every online service provider adopts these best practices and continues to work to protect their networks and their users.”
