Harnessing the Power of the People: Cloudflare’s First Security Awareness Month Design Challenge Winners

Grabbing the attention of employees at a security and privacy-focused company on security awareness presents a unique challenge; how do you get people who are already thinking about security all day to think about it some more? October marked Cloudflare’s first Security Awareness Month as a public company and to celebrate, the security team challenged our entire company population to create graphics, slogans, and memes to encourage us all to think and act more securely every day.

Employees approached this challenge with gusto; global participation meant plenty of high quality submissions to vote on. In addition to being featured here, the winning designs will be displayed in Cloudflare offices throughout 2020 and the creators will be on the decision panel for next year’s winners. Three rose to the top, highlighting creativity and style that is uniquely Cloudflarian. I sat down with the winners to talk through their thoughts on security and what all companies can do to drive awareness.

TCP MD5

TCP_MD5 (RFC 2385) is something that doesn’t come up often. There’s a couple of reasons for that, good and bad.

I used it with tlssh, but back then (2010) it was not practical due to the limitations in the API on Linux and OpenBSD.

This is an updated post, written after I discovered TCP_MD5SIG_EXT.

What it is

In short it’s a TCP option that adds an MD5-based signature to every TCP packet. It signs the source and destination IP addresses, ports, and the payload. That way the data is both authenticated and integrity protected.

When an endpoint enables TCP MD5, all unsigned packets (including SYN packets) are silently dropped. For a signed connection it’s not even possible for an eavesdropper to reset the connection, since the RST would need to be signed.

Because it’s on a TCP level instead of part of the protocol on top of TCP, it’s the only thing that can protect a TCP connection against RST attacks.

It’s used by the BGP protocol to set a password on the connection, instead of sending the password in the handshake. If the password doesn’t match the TCP connection doesn’t even establish.

But outside of BGP it’s essentially Continue reading

Rachel Player Honored by Internet Security Research Group with Radiant Award

Internet security is accomplished by many unsung heroes. People who put their talent and passion into improving the Internet, making it secure and trustworthy. This is a feature of the Internet: security isn’t achieved through a central mandate but through the hard work and tenacity of individuals working across the globe.

Rachel Player, a cryptographic researcher, is one of those unsung heroes. She’s just been awarded the Radiant Award from the Internet Security Research Group, the folks behind Let’s Encrypt, for her work in post-quantum cryptography and homomorphic encryption. Homomorphic encryption allows people to do computations on encrypted data, so that information can remain private and still be worked with. This is a highly-relevant field in any area that deals with sensitive and personal data, such as medicine and finance. Player is also interested in lowering the barriers for young people – young women, especially – to work professionally on topics like cryptography.

To learn more, read the announcement by the Internet Security Research Group and Rachel Player’s blog post about her work and her interest in making the profession more accessible.

Introducing Flan Scan: Cloudflare’s Lightweight Network Vulnerability Scanner

Today, we’re excited to open source Flan Scan, Cloudflare’s in-house lightweight network vulnerability scanner. Flan Scan is a thin wrapper around Nmap that converts this popular open source tool into a vulnerability scanner with the added benefit of easy deployment.

We created Flan Scan after two unsuccessful attempts at using “industry standard” scanners for our compliance scans. A little over a year ago, we were paying a big vendor for their scanner until we realized it was one of our highest security costs and many of its features were not relevant to our setup. It became clear we were not getting our money’s worth. Soon after, we switched to an open source scanner and took on the task of managing its complicated setup. That made it difficult to deploy to our entire fleet of more than 190 data centers.

We had a deadline at the end of Q3 to complete an internal scan for our compliance requirements but no tool that met our needs. Given our history with existing scanners, we decided to set off on our own and build a scanner that worked for our setup. To design Flan Scan, we worked closely with our auditors to understand Continue reading
