Cloudflare Bot Management: machine learning and more

Introduction

Building Cloudflare Bot Management platform is an exhilarating experience. It blends Distributed Systems, Web Development, Machine Learning, Security and Research (and every discipline in between) while fighting ever-adaptive and motivated adversaries at the same time.

This is the ongoing story of Bot Management at Cloudflare and also an introduction to a series of blog posts about the detection mechanisms powering it. I’ll start with several definitions from the Bot Management world, then introduce the product and technical requirements, leading to an overview of the platform we’ve built. Finally, I’ll share details about the detection mechanisms powering our platform.

Let’s start with Bot Management’s nomenclature.

Some Definitions

Bot - an autonomous program on a network that can interact with computer systems or users, imitating or replacing a human user's behavior, performing repetitive tasks much faster than human users could.

Good bots - bots which are useful to businesses they interact with, e.g. search engine bots like Googlebot, Bingbot or bots that operate on social media platforms like Facebook Bot.

Bad bots - bots which are designed to perform malicious actions, ultimately hurting businesses, e.g. credential stuffing bots, third-party scraping bots, spam bots and sneakerbots.

Bot Management - blocking Continue reading

AWS Networking 101

There was an obvious invisible elephant in the virtual Cloud Field Day 7 (CFD7v) event I attended in late April 2020. Most everyone was talking about AWS, how their stuff runs on AWS, how it integrates with AWS, or how it will help others leapfrog AWS (yeah, sure…).

Although you REALLY SHOULD watch my AWS Networking webinar (or something equivalent) to understand what problems vendors like VMWare or Pensando are facing or solving, I’m pretty sure a lot of people think they can get away with CliffsNotes version of it, so here they are ;)

Data centers are shrinking but not going away

The cloud will not kill the data center, but it will transform it. That's one of the takeaways from the 2020 State of the Data Center report from AFCOM, the industry association for data center professionals.In the near term, construction will slow way down, which aligns with what IDC analyst Rick Villars told me about data center construction slowing after a big buildout. More than 60% of respondents to the AFCOM report said they have no plans to build a new facility in the next 12 months, although 53% said they'll have at least one data center in the works over the next 36 months.

AWS Redirect URL with Route 53 and S3

I previously hosted my domains with GoDaddy. In their service it was pretty trivial to redirect a URL from one domain to another. I own the domain bradleysearle.com and I redirect it to https://codingpackets.com/about. The process to do this is not as simple with AWS so in this post I...

NVIDIA’s aggressive purchases could signal the era of open networking

NVIDIA’s plans to acquire Cumulus Networks, a pioneer of using open source for networking, is a sign that open networking is finally ready for a big leap forward.Open networking has been tightly coupled with software-defined networking (SDN) because the combination promises to make networks significantly more agile, open and easier to customize to specific needs. Cumulus has been working on it for years, and NVIDIA started pushing into it when it acquired Mellanox last week.[Get regularly scheduled insights by signing up for Network World newsletters.] The question the Cumulus acquisition raises is “why now”? The concept of open networking has been hotly debated since SDN came into prominence. The concept is sound, and open systems will disrupt the network industry much as it did the compute space. Yet while Linux and open source are wildly successful in the compute industry, open source has yet to take off in networking outside of webscale networks and a handful of large organizations.To read this article in full, please click here

NVIDIA, Mellanox, and Cumulus

Recent press releases, Riding a Cloud: NVIDIA Acquires Network-Software Trailblazer Cumulus and NVIDIA Completes Acquisition of Mellanox, Creating Major Force Driving Next-Gen Data Centers, describe NVIDIA's moves to provide high speed data center networks to connect compute clusters that use of their GPUs to accelerate big data workloads, including: deep learning, climate modeling, animation, data visualization, physics, molecular dynamics etc.

Real-time visibility into compute, network, and GPU infrastructure is required manage and optimize the unified infrastructure. This article explores how the industry standard sFlow technology supported by all three vendors can deliver comprehensive visibility.

Cumulus Linux simplifies operations, providing the same operating system, Linux, that runs on the servers. Cumulus Networks and Mellanox have a long history of working with the Linux community to integrate support for switches. The latest Linux kernels now include native support for network ASICs, seamlessly integrating with standard Linux routing (FRR, Quagga, Bird, etc), configuration (Puppet, Chef, Ansible, etc) and monitoring (collectd, netstat, top, etc) tools.

Linux 4.11 kernel extends packet sampling support describes enhancements to the Linux kernel to support industry standard sFlow instrumentation in network ASICs. Cumulus Linux and Mellanox both support the new Linux APIs. Cumulus Linux uses the open source Continue reading

New 6 GHz Wi-Fi could add $153 billion to U.S. economy: report

Opening the 6 GHz band to Wi-Fi could add $153.75 billion to the U.S. economy over the next five years, according to a new study.In late April, the Federal Communications Commission adopted rules that make 1,200 megahertz of spectrum in the 6 GHz band available for unlicensed use. Freeing up the chunk of 6 GHz spectrum for Wi-Fi is the biggest frequency allocation upgrade to the now aging wireless protocol in 10 years. Wi-Fi using 5 GHz spectrum – the last major touch-up – was introduced in 2009. The original 2.4 GHz Wi-Fi was introduced in 1997.To read this article in full, please click here

Cinco de Mayo – What are we celebrating anyway?

Greetings from Latinflare, Cloudflare’s LatinX Employee Resource Group, with members all over the US, the UK, and Portugal. Today is Cinco de Mayo! Americans everywhere will be drinking margaritas and eating chips and salsa. But what is this Mexican holiday really about and what exactly are we celebrating?

About Cinco de Mayo

Cinco de Mayo, Spanish for "Fifth of May", is an annual celebration held in Mexico on May 5th. The date is observed to commemorate the Mexican Army's victory over the French Empire at the Battle of Puebla, on May 5, 1862, under the leadership of General Ignacio Zaragoza. The victory of the smaller Mexican force against a larger French force was a boost to morale for the Mexicans. Zaragoza died months after the battle due to illness. A year after the battle, a larger French force defeated the Mexican army at the Second Battle of Puebla, and Mexico City soon fell to the invaders.

In the United States, Cinco de Mayo has taken on a significance beyond that in Mexico. More popularly celebrated in the United States than Mexico, the date has become associated with the celebration of Continue reading
