Cybersecurity

I visited today IoT Security Workshop at Aalto University (at Espoo Finland). Here are some slides from seminar →

http://www.osa.org/en-us/about_osa/newsroom/news_releases/2017/high-dimensional_quantum_encryption_performed_in_r/ For the first time, researchers have sent a quantum-secured message containing more than one bit of information per photon through the air above a city. The demonstration showed that it could one day be practical to use high-capacity, free-space quantum communication to create a highly secure link between ground-based networks and satellites, a requirement →

http://www.techrepublic.com/article/how-to-prevent-root-login-on-your-linux-servers/ If you’re overly paranoid about security (which you should be), you might want to consider blocking root logins on your Linux servers. Here’s how to do it. →

http://bigthink.com/videos/brad-templeton-todays-surveillance-society-is-beyond-orwellian Here is an interesting video: Brad Templeton (former chair of EFF) argues that we’re all a part of a surveillance apparatus that would even be beyond the imagination George Orwell. The problem, he says, is the belief that privacy and security are mutually exclusive.  →

https://opensource.com/article/17/1/rsync-backup-linux?sc_cid=7016000000127ECAAY All companies, regardless of how large or small, run on their data. There is not a business today ranging from the smallest sole proprietorship to the largest global corporation that could survive the loss of all or even a large fraction of its data.  So backups are imperative to ensure the long-term safety of data. There →

https://www.cyberciti.biz/tips/linux-security.html Securing your Linux server is important to protect your data, intellectual property, and time, from the hands of crackers (hackers). The system administrator is responsible for security of the Linux box. This article will provide 40 hardening tips for default installation of Linux system. →

https://arstechnica.com/information-technology/2017/08/a-repair-shop-could-completely-hack-your-phone-and-you-wouldnt-know-it/ Booby-trapped touchscreens can log passwords, install malicious apps, and more. People with cracked touch screens or similar smartphone maladies have a new headache to consider: the possibility the replacement parts installed by repair shops contain secret hardware that completely hijacks the security of the device. The research, in a paper presented this week at the 2017 Usenix →

http://www.darkreading.com/vulnerabilities—threats/taking-down-the-internet-has-never-been-easier/a/d-id/1329580 Is there a reason why the Internet is so vulnerable? Actually, there are many, and taking steps to remain protected is crucial. On October 29, 1969, two computers linked via telephone exchanged a couple of letters, then crashed.  Fast-forward 48 years, where everything — including the kitchen sink, in the case of smart kitchens — is →

That’s exactly the question Google’s security researchers Ellie Bursztein, Jean-Michel Picod, and Rémi Audebert addressed in their talk, “Attacking encrypted USB keys the hard(ware) way,” at the recent Black Hat →

http://spectrum.ieee.org/the-human-os/computing/software/researchers-embed-malicious-code-into-dna-to-hack-dna-sequencing-software This sounds like plot from scifi movie: University of Washington researchers successfully stored malware in synthetic DNA strands, and used it to gain control of the computer analyzing it. Researchers at the University of Washington have shown that by changing a little bit of computer code they can insert malware into a strand of →
