When you buy a new house, you shouldn’t have to worry that everyone in the city can unlock your front door with a universal key before you change the lock. You also shouldn’t have to walk around the house with a screwdriver and tighten the window locks and back door so that intruders can’t pry them open. And you really shouldn’t have to take your alarm system offline every few months to apply critical software updates that the alarm vendor could have fixed with better software practices before they installed it.
Similarly, you shouldn’t have to worry that when you buy a network discovery tool it can be accessed by any attacker until you change the password, or that your expensive hardware-based firewalls can be recruited to launch DDoS attacks or run arbitrary code without the need to authenticate.
This “default secure” posture is the focus of a recently published guide jointly authored by the Cybersecurity and Infrastructure Agency (CISA), NSA, FBI, and six other international agencies representing the United Kingdom, Australia, Canada, Germany, Netherlands, and New Zealand. In the guide, the authors implore technology vendors to follow Secure-by-Design and Secure-by-Default principles, shifting the burden of security as much Continue reading
Oxy: Fish/Bumblebee/Splicer subsystems to improve reliability
At Cloudflare, we are building proxy applications on top of Oxy that must be able to handle a huge amount of traffic. Besides high performance requirements, the applications must also be resilient against crashes or reloads. As the framework evolves, the complexity also increases. While migrating WARP to support soft-unicast (Cloudflare servers don't own IPs anymore), we needed to add different functionalities to our proxy framework. Those additions increased not only the code size but also resource usage and states required to be preserved between process upgrades.
To address those issues, we opted to split a big proxy process into smaller, specialized services. Following the Unix philosophy, each service should have a single responsibility, and it must do it well. In this blog post, we will talk about how our proxy interacts with three different services - Splicer (which pipes data between sockets), Bumblebee (which upgrades an IP flow to a TCP socket), and Fish (which handles layer 3 egress using soft-unicast IPs). Those three services help us to improve system reliability and efficiency as we migrated WARP to support soft-unicast.

Most transmission tunnels in our proxy forward packets without making any modifications. In other words, given Continue reading
Accelerating Chip Design With GPUs, And Adding AI To Push It Further
Two decades ago, all the chip makers, including Intel, had to buy Unix machines, usually massive ranks of Sparc/Solaris systems, to do electronic design automation to design and test their chip designs. …

Multi-Vendor EVPN Fabrics
Daniel left an interesting comment on my Studying EVPN to Prepare for a Job Interview blog post:
I also never build a VXLAN fabric with two vendors. So, is it possible now to build one large fabric consisting of multiple vendors?
TL&DR: Yes, but just because you could doesn’t mean that you should.

Day Two Cloud 191: Modernizing Cloud Security And Optimizing Costs With Jo Peterson
Today's Day Two Cloud delves into cloud security and cloud cost optimization for SaaS and public clouds. Our guest is Jo Peterson. On the security front, we compare and contrast traditional on-prem and cloud security challenges, explore the shared responsibility model of cloud security, and more. For cost optimization we discuss the growing concern about cloud costs, why optimization tools still need humans, tips for tracking multicloud spending, and more.Day Two Cloud 191: Modernizing Cloud Security And Optimizing Costs With Jo Peterson
