A container identity bootstrapping tool

Everybody has secrets. Software developers have many. Often these secrets—API tokens, TLS private keys, database passwords, SSH keys, and other sensitive data—are needed to make a service run properly and interact securely with other services. Today we’re sharing a tool that we built at Cloudflare to securely distribute secrets to our Dockerized production applications: PAL. PAL is available on Github: https://github.com/cloudflare/pal. Although PAL is not currently under active development, we have found it a useful tool and we think the…

A New Rule of 3s for Survival

My new rule of 3s for survival – – three weeks without food, three days without water, three minutes without air, and three seconds without an Internet connection!!  From Fast Company – the impact of the Internet in your pocket and how it changed everything. “In 2007 we were still thinking, “Why would I want the internet in my pocket when I’m walking around? If I want to get on the internet I’ll sit down in front of my computer.” So 50…

Stupidly Simple DDoS Protocol (SSDP) generates 100 Gbps DDoS

Last month we shared statistics on some popular reflection attacks. Back then the average SSDP attack size was ~12 Gbps and largest SSDP reflection we recorded was: 30 Mpps (millions of packets per second) 80 Gbps (billions of bits per second) using 940k reflector IPs This changed a couple of days ago when we noticed an unusually large SSDP amplification. It’s worth deeper investigation since it crossed the symbolic threshold of 100 Gbps. The packets per second chart during the…

Peikert This is a schematic illustration of quantitative measurements of mitochondrial building blocks using mass spectrometry. Credit: Artwork: Christian D. Peikert Close Mitochondria, best known for their role as powerhouses of eukaryotic cells, fulfill numerous vital functions. Knowledge about the precise protein composition as well as the functions of individual proteins is essential to understand fundamental processes of cell biology and…

Announcing the Cloudflare Apps Platform and Developer Fund

When we started Cloudflare we had no idea if anyone would validate our core idea. Our idea was what that everyone should have the ability to be as fast and secure as the Internet giants like Google, Facebook, and Microsoft. Six years later, it’s incredible how far that core idea has taken us. CC BY-SA 2.0 image by Mobilus In Mobili Today, Cloudflare runs one of the largest global networks. We have data centers in 115 cities around the world…

Communication between genes is the key — ScienceDaily

When Mark Martindale decided to trace the evolutionary origin of muscle cells, like the ones that form our hearts, he looked in an unlikely place: the genes of animals without hearts or muscles. In a new study published in the journal Proceedings of the National Academy of Sciences, the University of Florida scientist and colleagues found genes known to form hearts cells in humans and other animals in the gut of a muscle-less and heartless sea anemone. But the sea…

Researchers design sounds that can be recorded by microphones but inaudible to humans

The sound’s frequency is designed by the researchers and transmitted from ultrasonic speakers, completely inaudible to humans but able to be recorded by microphones. Credit: Coordinated Science Laboratory Microphones, from those in smartphones to hearing aids, are built specifically to hear the human voice—humans can’t hear at levels higher than 20 kHz, and microphones max out at around 24 kHz, meaning that microphones only capture the sound we can hear with our ears. However, researchers at the Coordinated Science Laboratory…

Bug-proof communication with entangled photons

Fraunhofer IOF‘s quantum source. Designed to be fully operational even after extreme stress. Credit: Fraunhofer IOF Due to the rapidly growing processing power of computers, conventional encryption of data is becoming increasingly insecure. One solution is coding with entangled photons. Fraunhofer researchers are developing a quantum coding source that allows the transport of entangled photons from satellites, thereby making an important step in the direction of tap-proof communication. In addition to the quantum source, researchers from various Fraunhofer institutes will…

Evolution of Dropbox’s Edge Network

Since launching Magic Pocket last year, we’ve been storing and serving more than 90 percent of our users’ data on our own custom-built infrastructure, which has helped us to be more efficient and improved performance for our users globally. But with about 75 percent of our users located outside of the United States, moving onto our own custom-built data center was just the first step in realizing these benefits. As our data centers grew, the rest of our network also…
