Keeping your digital presence continuously tuned, optimized, and secure to align with changing business and technical requirements can be time consuming. That’s why we’ve put together our Quick Value Packages — a collection of expert consulting services focused on performance, analytics, and security. Each one allows you to tap into Fastly’s expertise to keep up with the ongoing change and complexity of modern businesses — all while freeing up your IT and engineering resources. You’ll deliver quick wins and delight your teams, enabling you to focus on driving your business forward.

To help our customers secure their sites and applications — while continuing to give their users reliable online experiences — we’ve built a performant, highly configurable, and comprehensive Web Application Firewall (WAF). In order to provide a comprehensive solution for securing your infrastructure, it’s critical to continuously test that solution. In this post, we’ll share how we ensure a quality WAF implementation for our customers, continuously testing it using our framework for testing WAFs (FTW), and go deeper into the findings and contributions we’ve made to the OWASP CRS community with FTW.

Legacy WAFs were a stopgap that compliance regulations forced many to adopt (or at least pretend to). Learn more about why they fail and how the next generation of WAFs bridges the gap.

In part one of this series, we took a look at the evolving DDoS landscape, offering a sense of what’s out there in terms of attack size and type to help better inform decisions when it comes to securing your infrastructure. In this post, we’ll share an inside look at how we protect our customers, lessons learned from a real-live DDoS, and our recommended checklist for mitigating attacks.

As part of our vision for defending the modern web, the Fastly engineering teams are focused on providing you with a robust and secure platform that empowers you to protect your customers. Because we’re committed to providing secure experiences, we’re requiring clients that connect to our infrastructure to support TLS 1.2. Read on to learn about our deprecation plan, plus how to check which TLS version you’re using.

On October 26, we hosted an evening of drinks, snacks, and an excellent security discussion with the security research and engineering communities. Folks gathered at Bespoke Central Lounge in downtown San Francisco to hear from Alex Bazhaniuk, of Eclypsium, Inc., and Stephen Checkoway, of the University of Illinois. Watch the videos from their talks here.

On Wednesday, January 3rd, research was published on a class of security vulnerabilities affecting specific processors. These vulnerabilities could allow a user who can execute code on a system to gain unauthorized access to information across security boundaries. Fastly has completed initial analysis of these vulnerabilities and does not believe they pose an immediate threat to Fastly customers.

From August 31st through November 4th, Fastly deployed a version of Varnish which contained a security bug that, in a limited and non-standard set of configurations, disclosed request bodies to other customer origins. In these cases, a request body sent to an affected Fastly customer's service would have been included in a malformed request to a different customer's origin, which may have been logged in that origin web server's access logs. Fastly performed a comprehensive assessment to identify customers most likely to be affected by this issue. These customers have been contacted directly by Fastly Customer Engineering.

As an edge cloud platform, Fastly is in a unique position to monitor DDoS attack patterns and trends as they evolve. In this post, Jose Nazario, Sr. Director of Security Research, and Ryan Landry, Director of Edge Cloud Operations, take a look back at the history of DDoS, sharing how they’re changing and the trends we’re seeing. Getting a handle on the various shapes and sizes of DDoS will help inform how you address these attacks on your own infrastructure — you may not always be able to predict attacks, but knowing what’s out there and preparing for the worst will help you protect and mitigate.

We’re pleased to announce the next installment of our Security Speaker Series, which brings together researchers and engineers to share research, tools, and ideas. Join us for drinks, snacks, and a few hours of excellent security discussion on Thursday, Oct. 26 at 6pm PT at Bespoke Central Lounge in downtown San Francisco. Speakers include Alex Bazhaniuk, of Eclypsium, Inc., and Stephen Checkoway, of the University of Illinois.

In keeping with our security team’s vision for defending the modern web, we launched our Web Application Firewall (WAF) to help our customers secure their sites and applications while providing reliable online experiences for their users. In this post, two of the engineers who built our WAF will take you on a deep dive into the tech behind it, exploring how we built a performant, highly configurable, and comprehensive solution to secure customers’ infrastructure.

Deliberate practice is the act of performing a set of tasks that are just slightly more difficult than what you’re used to, so you can get better at a specific activity and move from a novice to an experienced practitioner. In this post, Security Engineer Sandra Escandor-O’Keefe walks us through the art of deliberate practice, offering tips for novices and mentors alike.

During the investigation of a customer report, Fastly became aware of and addressed a security vulnerability (CVE-2017-13761) in the Fastly CDN module intended to be integrated into Magento2. This is open source code which Fastly releases to enable easy integration with our partner’s products. All versions prior to 1.2.26 are affected and customers are encouraged to upgrade. Fastly has reached out directly to customers currently using affected versions of the module.

We need technology to provide capabilities to tackle the challenge of the cybersecurity gaps, recently highlighted by the WannaCry attacks. In this post, Director of Security Research Jose Nazario will explore these challenges as well as share research objectives that industry and academia must address soon before we can begin solving the security issues with IoT.

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.

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.

Understand how malware attacks happen to IoT devices and what companies can do to protect their devices from attacks.

We publish our security advisories to address vulnerabilities discovered on our own platform, as well as significant security vulnerabilities that affect the wider internet community.

On Monday, November 14, 2016, security researchers published a paper “Measuring the Security Harm of TLS Crypto Shortcuts.” Among other findings across the TLS implementation of several sites, the paper identified Fastly as not frequently rotating TLS session tickets, limiting the effectiveness of forward secrecy. While Fastly was not directly contacted by the researchers, Fastly had previously been made aware of the issue, and this vulnerability was addressed on Friday, November 11. No customer action is required to benefit from the fix.

On October 21st, 2016, Dyn, a major managed DNS provider, experienced a Distributed Denial of Service attack, which led to outages affecting several major websites, including Fastly infrastructure (such as the Fastly Control Panel and API) and Fastly customers. Fastly worked with our additional managed DNS providers to ensure availability during the incident. This mitigated impact on Fastly customers.
