In our year-end blogpost in December of 2015 we highlighted the enormous progress that IPv6 deployment had made in 2015 by obtaining aggregated data from our sources for the four major US mobile providers:
At SSL Labs, we have a major review of our grading criteria about once a year. As the security of the ecosystem matures, our goal is to push forward and make the requirements [for a good grade]…
Three months ago we launched the public beta of Vector at the electric atmosphere of the Decentralized Web Summit, bringing our…
Security protocols often assume an accurate, local clock (e.g. TLS, Kerberos, DNSSEC and more). It's a widely accepted assumption when designing protocols but, for a lot of people, it just isn't true. We find good evidence that at least 25% of all certificate errors in Chrome are due to a bad local clock.
Distributed Denial of Service (DDoS) attempts to make a machine or network unavailable by flooding it with overwhelming amounts of traffic.
Tor is a service run by a network of volunteers to allow people to use internet anonymously. Normally tor is used to browse the web without being tracked or identified.

As if 2016 wasn’t long enough, this year, a leap second will cause the last day of December to be one second longer than normal. But don’t worry, we’ve built support for the leap second into the time servers that regulate all Google services.
While hackers do good most of the time, we occasionally do evil and play a prank. The ESP8266, unlike JSON , allows me to do evil. Thus, I programmed the microcontroller for an evil purpose: slow down the WiFi.
The militia-patriot movement in America has embraced radio communications in a big way. Within the past decade, the methods and communications gear have evolved from basic CB or FRS radios, to now …
Over the last month, we’ve been watching some of the largest distributed denial of service (DDoS) attacks ever seen unfold. As CloudFlare has grown we've brought on line systems capable of absorbing and accurately measuring attacks.
I really love ping! It is easy to use and directly reveals whether the network works or not. Refer to Why Ping is no Security Flaw! (But your Friend) and Advanced Tracerouting . At least outgoing pings (from trust to untrust) should be allowed without any security concerns. However, many companies are denying these…

A buffer overflow error in GNU libc DNS stub resolver code was announced last week as CVE-2015-7547. While it doesn't have any nickname yet (last year's Ghost was more catchy), it is potentially disastrous.
I recently wanted a way to get a network packet trace from a specific application. My googling showed me an old askubuntu thread that solve...
