How to bootstrap self-service continuous fuzzing

OSS-Fuzz is an innovative project that is both advancing the state of the art in OSS security engineering and immediately improving the overall quality of the software that serves the internet. In this blog post, I’ll describe how to use the open source components of google/oss-fuzz to bootstrap self-service continuous fuzzing for both private and public software using h2o, Fastly’s HTTP/2 proxy, as a running example.

The IoT industry’s response to emerging threats

Late last year, we took a look at how the Internet of Things (IoT) is under attack. We analyzed hundreds of individual IoT devices to see how often they were probed for vulnerabilities, with the intention of being employed for IoT botnet attacks. We did more robust vulnerability research on IoT devices that have been found vulnerable in the past and concluded that while malicious probes are constant, manufacturers have taken action to update their firmware and address security holes. Read on to hear our latest findings.

Phase two of our TLS 1.0 and 1.1 deprecation plan

In February of last year we updated you on our plans to deprecate TLS 1.0 and 1.1 due to a mandate by the PCI Security Standards Council as well as our continued commitment to maintaining a trusted platform. Since then, we’ve observed a significant reduction in legacy TLS traffic on our network — here is the latest update on our deprecation plan.

The anatomy of an IoT botnet attack

We took a look at some of the more recent (and troubling) threats on the internet, and found that the emerging IoT market is under attack. Internet-connected devices are being churned out of factories and infected by malware, or malicious code, at an alarming rate. Just how big of a problem is this? We did an analysis of the anatomy of an IoT botnet attack — here’s what we found.

Lean Threat Intelligence, Part 4: Batch alerting

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.

Best practices for protecting your domain

We continuously work on making the edge more secure, and develop features you can leverage to protect your applications. However, in order for you to benefit from these investments, there are steps you should take at the crucial stage where traffic is handed off to the CDN. In this post, Director of Security Engineering Maarten Van Horenbeeck discusses how (and why) you can protect traffic on its way to the CDN.

Sponsoring the Tor project with content delivery services

Fastly has historically supported many open source projects. We’re happy to announce that Fastly now provides sponsored Content Delivery for the Tor Project. TorBrowser updates are served over the Fastly network, taking load off of the Tor Project's backend servers and speeding up downloads for end users.

Lean Threat Intelligence Part 3: Battling log absurdity with Kafka

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.
