Cloudflare is a service that acts as a middleman between a website and its end users, protecting it from various attacks. Unfortunately, those websites are often poorly configured, allowing an attacker to entirely bypass Cloudflare and run DDoS attacks or exploit web-based vulnerabilities that would otherwise be…

QUIC (Quick UDP Internet Connections) is a new encrypted-by-default Internet transport protocol, that provides a number of improvements designed to accelerate HTTP traffic as well as make it more secure, with the intended goal of eventually replacing TCP and TLS on the web.
Some thoughts on security after ten years of qmail 1.0 Bernstein, 2007 I find security much more important than speed. We need invulnerable software systems, and we need them today, even if they ar…

I recently found myself dealing with TCP load balancing for a project and I've come to think that generic TCP proxies can't be implemented without substantial pain and how it makes TLS terminating proxies a bad idea.
DNSSEC is a system of digital signatures that prevent DNS spoofing. Using DNSSEC, it does not matter where your DNS answers came from, since the DNS resolver or application can verify the DNSSEC signatures to ensure the DNS data is not tampered with..DNS is hierarchical, which means that the parent zone vouches for…
Developers already use HTTPS to communicate with Firebase Cloud Messaging (FCM). The channel between FCM server endpoint and the device is encrypted with SSL over TCP. However, messages are not encrypted end-to-end (E2E) between the developer server and the user device unless developers take special measures. To this…
Thanks to the RIPE NCC Community Project Fund we were able to revive the OpenBGPD daemon and bring more diversity to the Route Server landscape.
In this short post I’m going to attempt to convince you that current network (Internet) latencies are here to stay, because they are already within a fairly small factor of what is possible u…
For better or worse, Requests for Comments (RFCs) are how we specify many protocols on the Internet. These documents are alternatively treated as holy texts by developers who parse them for hidden meanings, then shunned as irrelevant because they can’t be understood. This often leads to frustration and – more…
In the last few days I've been fortunate to witness an interesting chapter in the Internet's history, and I'm trying to compile a timeline of what has happened while the memories are still reasonably fresh. This is incomplete and a work in progress; I'll be updating it, and n...
by Annie Edmundson, Paul Schmitt, Nick Feamster The recent news that Cloudflare is deploying their own DNS recursive resolver has once again raised hopes that users will enjoy improved privacy, since they can send DNS traffic encrypted to Cloudflare, rather than to their ISP. In this post, we explain why this approach…

Guest post: BGP gets a bad rap from some but maybe the problem is with people not the protocol.
Two years ago this week Cloudflare introduced Opportunistic Encryption, a feature that provided additional security and performance benefits to websites that had not yet moved to HTTPS.

Recently, Oculus teamed up with developer Glenn Fiedler for research into networked physics in VR. Below is a guest post from Glenn detailing his research.
