  • The headers we don't want

    Andrew Betts

    HTTP headers are an important way of controlling how caches and browsers process your web content. But many are used incorrectly or pointlessly, which adds overhead at a critical time in the loading of your page, and may not work as you intended.

  • Lean Threat Intelligence, Part 4: Batch alerting

    Zack Allen

    In Part 3, we showcased a technology that allows you to route messages to and from topics via Kafka. Now that data is flowing, how can you start monitoring and reacting to security events? In this post, we’ll show you a batch alerting strategy that you can use with Graylog and Kafka.

  • Battling log absurdity with Kafka

    Zack Allen

    In “Lean Threat Intelligence Part 2: The foundation,” we explained how we built our log management system, Graylog, using Chef. Next, we’ll cover how we created a message pipeline that allows us to route messages to different endpoints for analysis or enrichment.

  • Diff at the edge with serverless cloud functions

    Andrew Betts

    Requesting the difference between two previously cached files — using just a CDN configuration and a serverless cloud compute function — is a great example of exploiting edge and serverless compute services to make your website more efficient and performant, and lower your bandwidth costs. Read on to learn more.

  • Cache hit ratios at the edge: a performance study

    Hooman Beheshti

    In an earlier post, we discussed the meaning of cache hit ratio (CHR) and analyzed what the metric is and isn’t telling us, showing why we really need two different CHR metrics (CHR-edge and CHR-global) to fully understand how a CDN is serving your clients. In this post, we’ll analyze CHR-edge by way of a discussion about performance measurement via testing.

  • Understanding the Vary header in the browser

    Andrew Betts

    Browsers need to understand and respond to Vary rules, and the way they do this is different from the way Vary is treated by CDNs. In this post, Principal Developer Advocate Andrew Betts explores the murky world of cache variation in the browser.

  • Hijacking the control flow of a WebAssembly program

    Jonathan Foote

    While WebAssembly has already proven a fertile attack surface for the browser, as more web application code moves to WebAssembly from Javascript there will be a need to research and secure WebAssembly programs themselves. The WebAssembly design obviates common classes of attacks that might be inherited from development languages like C and C++, but there is still some room for exploitation. This tutorial will cover control flow protection guarantees provided by WebAssembly, known weaknesses, and how to use clang control flow integrity (CFI) in WebAssembly programs to mitigate some risks around control flow hijacks.

  • Scaling Fastly Network: Fighting FIB | Fastly

    João Taveira Araújo

    This post is the first in a series detailing the evolution of network software at Fastly. We’re unique amongst our peers in that from inception, we’ve always viewed networking as an integral part of our product rather than a cost center. We rarely share what we do with the wider networking community however, in part because we borrow far more from classic systems theory than contemporary networking practice.
