And why it’s vital to the future of the internet, Northeastern computer scientist explains Computer Science professor David Choffnes says the principle was - and remains - crucial to the development of the internet. NSF grant will allow researchers from around the world to improve security of smart devices — remotely NSF grant will allow researchers from around the world to improve security of smart devices — remotely Northeastern's new IoT laboratory offers access to 500 devices, enabling technical research in cybersecurity and privacy on a global scale. Automakers cleared in privacy lawsuit. Are your texts and call logs at risk? And what other data is being collected? Automakers cleared in privacy lawsuit. Are your texts and call logs at risk? And what other data is being collected? A cybersecurity expert reacts and says this decision raises the question as to what other data automakers might be collecting. The smart home tech inside your home is less secure than you think, new Northeastern research finds The smart home tech inside your home is less secure than you think, new Northeastern research finds A team of researchers discovered vulnerabilities in smart home devices made by big technology companies like Google. TikTok won’t be banned from US app stores. Here’s why. TikTok won’t be banned from US app stores. Here’s why. TikTok doesn’t pose a national security threat to the U.S. any more than some of our most beloved apps such as Facebook and Twitter, says David Choffnes, associate professor of computer science. Banning the app would require a vote from Congress and massive changes in net neutrality. Are Alexa, Siri, and Cortana recording your private conversations? Are Alexa, Siri, and Cortana recording your private conversations? Smart speakers aren’t recording all the time, says associate professor David Choffnes. “But that doesn’t mean there’s no cause for concern.” Facial recognition technology: In our rush to deploy it, are we ignoring the risks? Facial recognition technology: In our rush to deploy it, are we ignoring the risks? London has announced that it will install cameras across the city to catch and identify criminal suspects, joining a growing list of cities that have embraced facial recognition technology. David Choffnes, whose research focuses on network security and privacy, cautions that with so much at stake, it’s worth considering the potential risks of public surveillance tools before rushing to deploy them.
