IPv6 represents new territory for most Internet stakeholders, and its rollout will introduce some unique security challenges.

DDOS Attackers - Who and Why?

Bruce Schneier's recent blog post, "Someone is Learning How to Take Down the Internet", reported that the incidence of DDOS attacks is on the rise. And by this he means that these attacks are on the rise both in the number of attacks and the intensity of each attack. A similar observation was made in the Versign DDOS Trends report for the second quarter of 2015, reporting that DDOS attacks are becoming more sophisticated and persistent in the second quarter of 2016. more»

Does Apple's Cloud Key Vault Answer the Key Escrow Question?

In a recent talk at Black Hat, Apple's head of security engineering (Ivan Krstić) described many security mechanisms in iOS. One in particular stood out: Apple's Cloud Key Vault, the way that Apple protects cryptographic keys stored in iCloud. A number of people have criticized Apple for this design, saying that they have effectively conceded the "Going Dark" encryption debate to the FBI. They didn't, and what they did was done for very valid business reasons -- but they're taking a serious risk... more»

Internet Access: A Chokepoint for Development

In the 1980's internet connectivity meant allowing general public to communicate and share knowledge and expertise with each other instantly and where it was not possible otherwise. Take the story of Anatoly Klyosov, connecting Russia to the western world for the first time in 1982, as an example. A bio-chemist who was not allowed to leave the soviet territory for security reasons. The internet enabled him to participate in meetings with his counterparts at Harvard University, University of Stockholm and beyond. more»

China's QUESS and Quantum Communications

In mid-August China launched "QUESS" (Quantum Experiments at Space Scale), a new type of satellite that it hopes will be capable of "quantum communications" which is supposed to be hack-proof, through the use of "quantum entanglement". This allows the operator to ensure that no one else is listening to your communications by reliably distributing keys that are then used for encryption in order to be absolutely sure that there is no one in the middle intercepting that information. more»

Security Against Election Hacking - Part 2: Cyberoffense Is Not the Best Cyberdefense!

State and county election officials across the country employ thousands of computers in election administration, most of them are connected (from time to time) to the internet (or exchange data cartridges with machines that are connected). In my previous post I explained how we must audit elections independently of the computers, so we can trust the results even if the computers are hacked. more»

Security Against Election Hacking - Part 1: Software Independence

There's been a lot of discussion of whether the November 2016 U.S. election can be hacked. Should the U.S. Government designate all the states' and counties' election computers as "critical cyber infrastructure" and prioritize the "cyberdefense" of these systems? Will it make any difference to activate those buzzwords with less than 3 months until the election? First, let me explain what can and can't be hacked. Election administrators use computers in (at least) three ways... more»

Video: Interview with Jari Arkko at IETF 96 in Berlin

Would you like to understand the major highlights of the 96th meeting of the Internet Engineering Task Force (IETF) last month in Berlin? What were some of the main topics and accomplishments? How many people were there? What else went on? If so, you can watch a short video interview I did below with IETF Chair Jari Arkko. more»

NTP is Still a Security Risk

The Network Time Protocol (NTP) has been in the news a number of times over the past couple of years because of attacks on the protocol, vulnerabilities in the daemon, and the use of NTP in DDoS attacks. In each case, the developers of NTP have responded quickly with fixes or recommendations for remediating these attacks. Additionally, the development team has continued to look ahead and has worked to enhance the security of NTP. Unfortunately, that has not translated to an improved security picture for NTP. more»

Internet: Quo Vadis (Where are you going?)

Articles, blogs, and meetings about the internet of the future are filled with happy, positive words like "global", "uniform", and "open". The future internet is described in ways that seem as if taken from a late 1960's Utopian sci-fi novel: the internet is seen as overcoming petty rivalries between countries, dissolving social rank, equalizing wealth, and bringing universal justice. If that future is to be believed, the only obstacle standing between us and an Arcadian world of peace and harmony is that the internet does not yet reach everyone... more»

Final Day to Give Input on "Future of the Internet" Survey

Today, June 26, is the final day that you can help the Internet Society with its "Future of the Internet" survey. It takes about 20-25 minutes and will help my colleagues at the Internet Society develop a number of scenarios about the possible future of the Internet. These scenarios can help all of us in talking to policy makers, leaders, media and the general user population about the choices we have before us for the future of the Internet. more»
