My letter urging Georgia governor to veto anti-hacking bill
February 16, 2018Office of the Governor
206 Washington Street

Atlanta, Georgia 30334
Re: SB 315
Dear Governor Deal:
I am writing to urge you to veto SB315, the "Unauthorized Computer Access" bill.
The cybersecurity community, of which Georgia is a leader, is nearly unanimous that SB315 will make cybersecurity worse. You've undoubtedly heard from many of us opposing this bill. It does not help in prosecuting foreign hackers who target Georgian computers, such as our elections systems. Instead, it prevents those who notice security flaws from pointing them out, thereby getting them fixed. This law violates the well-known Kirchhoff's Principle, that instead of secrecy and obscurity, that security is achieved through transparency and openness.
That the bill contains this flaw is no accident. The justification for this bill comes from an incident where a security researcher noticed a Georgia state election system had made voter information public. This remained unfixed, months after the vulnerability was first disclosed, leaving the data exposed. Those in charge decided that it was better to prosecute those responsible for discovering the flaw rather than punish those who failed to secure Georgia voter information, hence this law.
Too many security experts oppose Continue reading
Let’s stop talking about password strength

| Picture from EFF -- CC-BY license |
Yes, weak passwords can be a problem. If a website gets hacked, weak passwords are easier to crack. It's not that this is wrong advice.
On the other hand, it's not particularly good advice, either. It's far down the list of important advice that people need to remember. "Weak passwords" are nowhere near the risk of "password reuse". When your Facebook or email account gets hacked, it's because you used the same password across many websites, not because you used a weak password.
Important websites, where the strength of your password matters, already take care of the problem. They use strong, salted hashes on the backend to protect the password. On the frontend, they force passwords to be a certain length and a certain complexity. Maybe the better advice is to not trust any website that doesn't enforce stronger passwords (minimum of 8 characters consisting of both letters and non-letters).
To some extent, this "strong password" advice has become obsolete. A decade ago, websites had poor protection (MD5 hashes) and no enforcement of complexity, so it Continue reading

Zededa Wants to Use the Cloud to Power IoT at the Edge
The company is building a software platform that can be deployed on virtually any edge device in support of IoT. This involves a lightweight software stack that can adapt to different deployment models.
Four Security Myths You Need to Shake
In this zero-trust world, no data is safe. In order to tighten security in cloud-based environments, enterprises must embrace the truth about security.
Security Research is Critical to Protect the Open Internet
On, April 10, 2018 I joined over fifty like-minded individuals signing a letter emphasizing the importance of security research. The letter renounces a number of recent lawsuits, such as Keeper v. Goodlin and River City Media v. Kromtech, against security researchers and journalists and highlights the importance of the work they are doing to defend against a rapidly increasing number of security threats.
Security research, sometimes called white-hat hacking, is a practice by ethical hackers whereby they legally find flaws in information systems and report them to the creators of those systems. The ability to find and report these vulnerabilities before other bad actors can manipulate them has become increasingly important, especially in the context of the Internet of Things (IoT).
As we discussed at Enhancing IoT Security in Ottawa, Canada this week, Internet-connected devices offer great promise, but they can also create a host of security issues. It is crucial that we continue to encourage individuals to seek out and correct flaws in these devices as their application and use grows.
As Olaf Kolkman, Chief Internet Technology Officer at the Internet Society, wrote recently, security researchers are helping to make the Internet more secure. Collaboration between those Continue reading
Successful First Event in the Canadian Multistakeholder Process – Enhancing IoT Security Series
On April 4, 2018, over 80 individuals met in Ottawa and virtually via livestream for the first event in the Canadian Multistakeholder Process – Enhancing IoT Security series. Participants represented a wide-range of stakeholder groups, including government, academia, public interest, and industry representatives. Two Internet Society Organization Members, the Canadian Internet Registration Authority and CANARIE, as well as Innovation, Science and Economic Development Canada and the Canadian Internet Policy and Public Interest Clinic were partners for this event. IoT security is a complex issue that requires all stakeholders to cooperate and participate in the development of solutions, and we were pleased to have such truly multistakeholder representation.
The event kicked off with an interactive presentation from Larry Strickling, Executive Director of the Collaborative Governance Project. Strickling provided an overview of the multistakeholder process and facilitated a discussion among participants to determine ground rules and define what constitutes consensus. Participants, both those remote and in person, outlined over a dozen rules and three key metrics for determining consensus, which will be used throughout the entirety of the project.
In the morning, participants heard from a series of speakers who presented on IoT security and risk, the balance between IoT’s technological Continue reading

Cloudflare launches 1.1.1.1 DNS service with privacy, TLS and more
There was an important development this month with the launch of Cloudflare’s new 1.1.1.1 DNS resolver service. This is a significant development for several reasons, but in particular it supports the new DNS-over-TLS and DNS-over-HTTPS protocols that allow for confidential DNS querying and response.
Why 1.1.1.1?
Before we get to that though, Cloudflare joins Google’s Public DNS that uses 8.8.8.8 and Quad9 DNS that uses 9.9.9.9, by implementing 1.1.1.1 as a memorable IP address for accessing its new DNS service. IP addresses are generally not as memorable as domain names, but you need access to a DNS server before you can resolve domain names to IP addresses, so configuring numbers is a necessity. And whilst a memorable IP address might be cool, it’s also proved important recently when DNS resolvers have been blocked or taken down, requiring devices to be pointed elsewhere.
The 1.1.1.1 address is part of the 1.1.1.0 – 1.1.1.255 public IP address range actually allocated to APNIC, one of the five Regional Internet Registries, but it has been randomly used as an address for Continue reading
Introducing Spectrum: Extending Cloudflare To 65,533 More Ports
Today we are introducing Spectrum, which brings Cloudflare’s security and acceleration to the whole spectrum of TCP ports and protocols for our Enterprise customers. It’s DDoS protection for any box, container or VM that connects to the internet; whether it runs email, file transfer or a custom protocol, it can now get the full benefits of Cloudflare. If you want to skip ahead and see it in action, you can scroll to the video demo at the bottom.
DDoS Protection
The core functionality of Spectrum is its ability to block large DDoS attacks. Spectrum benefits from Cloudflare’s existing DDoS mitigation (which this week blocked a 900 Gbps flood). Spectrum’s DDoS protection has already been battle tested. Just soon as we opened up Spectrum for beta, Spectrum received its first SYN flood.
One of Spectrum's earliest deployments was in front of Hypixel’s infrastructure. Hypixel runs the largest minecraft server, and because gamers can be - uh, passionate - they were one of the earliest targets of the terabit-per-second Mirai botnet. “Hypixel was one of the first subjects of the Mirai botnet DDoS attacks and frequently receives large attacks. Before Spectrum, we had to rely on unstable services & techniques Continue reading
Abusing Linux’s firewall: the hack that allowed us to build Spectrum
Today we are introducing Spectrum: a new Cloudflare feature that brings DDoS protection, load balancing, and content acceleration to any TCP-based protocol.
CC BY-SA 2.0 image by Staffan Vilcans
Soon after we started building Spectrum, we hit a major technical obstacle: Spectrum requires us to accept connections on any valid TCP port, from 1 to 65535. On our Linux edge servers it's impossible to "accept inbound connections on any port number". This is not a Linux-specific limitation: it's a characteristic of the BSD sockets API, the basis for network applications on most operating systems. Under the hood there are two overlapping problems that we needed to solve in order to deliver Spectrum:
- how to accept TCP connections on all port numbers from 1 to 65535
- how to configure a single Linux server to accept connections on a very large number of IP addresses (we have many thousands of IP addresses in our anycast ranges)
Assigning millions of IPs to a server
Cloudflare’s edge servers have an almost identical configuration. In our early days, we used to assign specific /32 (and /128) IP addresses to the loopback network interface[1]. This worked well when we had dozens of IP Continue reading
리눅스 방화벽을 남용하기: Spectrum 을 만들 수 있었던 해킹
This is a Korean translation of a prior post by Marek Majkowski.
얼마전 우리는 Spectrum을 발표하였습니다: 어떤 TCP 기반의 프로토콜이라도 DDoS 방어, 로드밸런싱 그리고 컨텐츠 가속을 할 수 있는 새로운 Cloudflare의 기능입니다.
CC BY-SA 2.0 image by Staffan Vilcans
Spectrum을 만들기 시작하고 얼마 되지 않아서 중요한 기술적 난관에 부딛히게 되었습니다: Spectrum은 1부터 65535 사이의 어떤 유효한 TCP 포트라도 접속을 허용해야 합니다. 우리의 리눅스 엣지 서버에서는 "임의의 포트 번호에 인바운드 연결을 허용"은 불가능합니다. 이것은 리눅스만의 제한은 아닙니다: 이것은 대부분 운영 체제의 네트워크 어플리케이션의 기반인 BSD 소켓 API의 특성입니다. 내부적으로 Spectrum을 완성하기 위해서 풀어야 하는 서로 겹치는 문제가 둘 있었습니다:
- 1에서 65535 사이의 모든 포트 번호에 TCP 연결을 어떻게 받아들일 것인가
- 매우 많은 수의 IP 주소로 오는 연결을 받아들이도록 단일 리눅스 서버를 어떻게 설정할 것인가 (우리는 애니캐스트 대역에 수많은 IP주소를 갖고 있습니다)
서버에 수백만의 IP를 할당
Cloudflare의 엣지 서버는 거의 동일한 구성을 갖고 있습니다. 초창기에는 루프백 네트워크 인터페이스에 특정한 /32 (그리고 /128) IP 주소를 할당하였습니다[1]. 이것은 수십개의 IP주소만 갖고 있었을 때에는 잘 동작 하였지만 더 성장함에 따라 확대 적용하는 것에는 실패하였습니다.
그때 "AnyIP" 트릭이 등장하였습니다. AnyIP는 단일 주소가 아니라 전체 IP 프리픽스 (서브넷)을 루프백 인터페이스에 할당하도록 해 줍니다. 사실 AnyIP를 많이 사용하고 있습니다: 여러분 컴퓨터에는 루브백 인터페이스에 Continue reading
