TLS 1.2-only delivery is now available
Earlier this year we updated you on our revised deprecation plan for TLS 1.0 and 1.1. We’re happy to announce that you can now request migration to TLS 1.2-only hosts if you’ve purchased a paid TLS option.
Announcing Limited Availability for HTTP/2
As promised in March of this year, we are excited to announce that our HTTP/2 Limited Availability (LA) program is here. Here’s how you get started.
Recapping our second Fastly Security Speaker Series
On May 25, we had over 50 security researchers and engineers from the Bay Area and beyond in our San Francisco office for our recurring Fastly Security Speaker Series. This event focused on hardware security, including how to detect firmware attacks, and how to execute hardware side-channel attacks.
Fastly Security Speaker Series: Second Edition
In February, our Chief Security Officer Window Snyder announced the Fastly Security Speaker Series, which we created to share cutting edge security topics with the wider community. We hosted over 50 security researchers and engineers in an event focused on machine learning and reverse engineering. Today, we’re happy to announce the second event in our Fastly Security Speaker Series, which will take place on May 25th from 6:00 to 8:45 pm. Join us at Fastly’s San Francisco headquarters for food, drinks, and ample opportunity for good discussion with your peers in the security research community. You can register to attend here.
Lean Threat Intelligence Part 2: The foundation
In part 1, I discussed the general workflow the Threat Intelligence team at Fastly uses to plan for projects. After performing research and seeing what others have done in this space, we can now move forward with technology selection.
College competitions build strong security teams | Fastly
Building a great team is one of the most difficult challenges security managers encounter. Luckily, there are a few initiatives that make things easier on us, including the Information Security Talent Search (ISTS) at the Rochester Institute of Technology.
Recap of the Fastly Security Speaker Series
On February 25, we hosted 50+ security researchers and engineers from the Bay Area and beyond in our San Francisco office for the first event in the Fastly Security Speaker Series. This event brought together security engineers and researchers to examine new perspectives around important security topics.
Lean Threat Intelligence, Part 1: The plan
Fastly Security Researcher Zack Allen discusses how you can draw from open source resources to build a lean and powerful Threat Intelligence plan for your organization.
Introducing Fastly Security Advisories
Today we’re announcing Fastly Security Advisories. Fastly will publish these to address security concerns that either trigger customer interest or require customer action to address.
Introducing the Fastly Security Speaker Series
Today we’re announcing the Fastly Security Speaker Series, an informal event for bringing together researchers and engineers to share research, tools, and ideas. Fastly will bring some of the most innovative and thoughtful security researchers to Fastly headquarters in San Francisco to share their work. Our first event is February 25th, and our first two speakers are Alex Pinto and Rolf Rolles.
Update to our TLS 1.0 and 1.1 deprecation plan
Last October, we announced our deprecation plan for TLS 1.0 and 1.1. The PCI Security Standards has since updated their guidance, and we are revising our deprecation schedule accordingly.
Fastly's plan for plan for TLS 1.0 and 1.1 deprecation
The PCI DSS 3.1 standard has changed. In order to keep you up-to-date and secure online, we’re announcing our plan for TLS 1.0 and 1.1 deprecation.
Engineering a more resilient internet
Fastly Director of Security Engineering Maarten Van Horenbeeck shares his experiences of how the security community can protect the “global commons” that the internet has become.
GitHub’s Joe Williams discusses mitigating security threats
At Fastly Altitude 2015, Joe Williams, a computer operator at GitHub, gave a talk on mitigating security threats (like DDoS attacks) with a CDN. This post is an overview of his talk, with full video and slides included.
How to fuzz a server with American Fuzzy Lop
In this blog post, I'll describe how to use AFL's experimental persistent mode to blow the doors off of a server without having to make major modifications to the server's codebase. I've used this technique at Fastly to expand testing in some of the servers that we rely on and others that we are experimenting with.
FREAK does not affect Fastly services
Fastly is not vulnerable to Logjam — we only offer the more secure Elliptic Curve variant of the Diffie-Hellman key exchange (ECDHE), and the RSA key exchange mechanism for clients that don’t support ECDHE. Since Fastly does not offer any export grade ciphersuite options — and we do not offer the Diffie-Hellman key exchange mechanism — our services are not affected.
Improve CA ops visibility with Cert Transparency | Fastly
If you follow the security news cycle, you may have seen recent discussions about Google detecting a Certificate Authority (CA) in China improperly issuing certificates capable of transparently (that is, without warning) imitating Google TLS-protected websites. As part of the subsequent investigation, Google removed the implicated CA from the list of trusted CAs and indicated that in order for the CA to be considered for re-inclusion, they would have to implement a system known as Certificate Transparency (CT). Below, I’ll outline the basics of CT and how it relates to this and other CA-related incidents in recent history.
Addressing TLS Revocation and OCSP Challenges
Rotation, expiration, and revocation of secrets are all important concerns that require careful and difficult up-front design. Transport Layer Security (TLS), the protocol underlying secure web traffic (HTTPS), is one of the cryptographic systems with the largest deployment and day-to-day use, and serves as a good case study for all of the proceeding concerns. In this post, I’ll discuss how revocation is addressed in TLS, and how it relates to both performance and security.
March 19 OpenSSL Security Advisory
Fastly has evaluated each of these vulnerabilities and found that only one moderate-severity bug affects our configuration. We are currently testing the patch and coordinating a global release of the updated software across Fastly’s network. We anticipate no customer impact or configuration changes.
TLS at the edge and server-side security
We’re huge fans of Transport Layer Security (TLS) at Fastly. Here’s a behind-the-scenes look at how we do encryption at the edge, which can also serve as overall best practices for handling server-side TLS.
