We built Access to solve a problem here at Cloudflare: our VPN. Our team members hated the slowness and inconvenience of VPN but, that wasn’t the issue we needed to solve. The security risks posed by a VPN required a better solution.
VPNs punch holes in the network perimeter. Once inside, individuals can access everything. This can include critically sensitive content like private keys, cryptographic salts, and log files. Cloudflare is a security company; this situation was unacceptable. We need a better method that gives every application control over precisely who is allowed to reach it.
Access meets that need. We started by moving our browser-based applications behind Access. Team members could connect to applications faster, from anywhere, while we improved the security of the entire organization. However, we weren’t yet ready to turn off our VPN as some tasks are better done through a command line. We cannot #EndTheVPN without replacing all of its use cases. Reaching a server from the command line required us to fall back to our VPN.
Today, we’re releasing a beta command line tool to help your team, and ours. Before we started using this feature at Cloudflare, curling a server required me to Continue reading
By now the story and resulting controversy is as much about media credibility as it is about cyber — and national — security.

It is safe to say that a little more than a decade ago, when the clone of Google’s MapReduce and Google File System distributed storage and computing platform was cloned at Yahoo and offered up to the world as a way to transform the nature of data analytics at scale, that we all had much higher hopes for the emergence of platforms centered around Hadoop that would change enterprise, not just webscale, computing. …

Rebooting Linux systems with Ansible has always been possible, but was often tricky and error-prone. In Ansible 2.7, I am happy to say that rebooting Linux hosts with Ansible is now easier and can be done with a single task using the newly minted reboot plugin.
The win_reboot module was written by Matt Davis and included with Ansible 2.1. Rebooting Windows hosts is a much more common occurrence than rebooting Linux hosts. Necessity is the mother of invention, so it made sense that win_reboot appeared before the equivalent for Linux. And while less than elegant, it is possible to reboot Linux hosts using shell and wait_for or wait_for_connection[1].
Rebooting Linux systems with Ansible never felt right to me — much too error prone and finicky. It finally bugged me enough that I refactored win_reboot into reboot so Linux hosts could join the reboot party with their Windows counterparts.
When I set out to make the reboot plugin[2], the goal was to create a common class that win_reboot (and potentially others) could easily subclass to override specific parts of the reboot process. I was also working in reverse, deconstructing win_reboot into a new Continue reading
Have you ever tried to implement something new and run into others who are resistant to that change? In this Short Take, Russ explores the validity of the commonly used “It’s always been done that way” excuse for avoiding change.

Security is a field of questions. We find ourselves asking
all kinds of them all the time. Who is trying to get into my network? What are
they using? How can I stop them? But I feel that the most important question is
the one we ask the least. And the answer to that question provides the
motivation to really fix problems as well as conserving the effort necessary to
do so.
If you’re someone with kids, imagine a conversation like
this one for a moment:
Your child runs into the kitchen with a lit torch in their hands and asks “Hey, where do we keep the gasoline?”
Now, some of you are probably laughing. And some of you are
probably imagining all kinds of crazy going on here. But I’m sure that most of
you probably started asking a lot of questions like:
Usually, the rest of the Five Ws follow Continue reading
