How to Move Cybersecurity Forward in a More Positive Way

In 2013 I wrote a blog Telecoms as a spying tool, in which I mentioned that those who use the internet to spy indiscriminately will have to face the reality that such activities will only start a cat-and-mouse game -- the technology will always be able to stay one step ahead of those who are using the internet for criminal purposes. Since that time some very significant developments have taken place that have confirmed our prediction. more

Deploying DNSSEC: Lessons from Domain Registrar Implementation

As a registrar at the front end of the DNSSEC deployment effort, our technical team has made a sustained investment in DNSSEC deployment so that our customers don't get overwhelmed by this wave of changes to the core infrastructure of the Domain Name System. Along the way, we've learnt a lot about how to implement DNSSEC which might hold useful lessons for other organizations that plan to deploy DNSSEC in their networks. more

Future Network Forum to Be Held in Nanjing in December 2015

Between December 10th and 11th 2015, the China Future Network Development and Innovation Forum, jointly hosted by the Chinese Academy of Engineering and the Nanjing Municipal Government, is scheduled to be held in Nanjing, Jiangsu, China. The forum will be jointly organized by Jiangsu Future Networks Innovation Institute and Beijing Internet Institute, with the theme of "Building future network test facilities and promoting network development & innovation", and it will invite nearly a hundred industrial experts at home and abroad, to establish a platform marked by security, innovation, openness, cooperation where the policy, industry, academics, and application are integrated. more

Cyber Security and the White House, Part 2 - Cyberwarfare

This is a follow-up to my previous post on Cybersecurity and the White House. It illustrates an actual cyberwarfare attack against Estonia in 2007 and how it can be a legitimate national security issue. Estonia is one of the most wired countries in eastern Europe. In spite of its status of being a former Soviet republic, it relies on the internet for a substantial portion of everyday life -- communications, financial transactions, news, shopping and restaurant reservations all use the Internet. Indeed, in 2000, the Estonian government declared Internet access a basic human right... more

A Look at Why We Need Fibre-to-the-Farm

One of the discussions I am currently having with my international colleagues is about the global trend towards urbanisation and the resulting shift of political, economic and financial powers from centralised states and federal structures to mega-city or mega-urban region centres. Some of my American colleagues expressed the fear that this would further marginalise rural communication. more

Collecting Cybercrime Data: Can Signal Spam Be a Piece of the Puzzle?

The gathering of coherent data on cybercrime is a problem most countries haven't found a solution for. So far. In 2011 it is a well known fact that spam, cybercrime and botnets are all interrelated. The French database Signal Spam may be a significant part of the solution to gather, analyse and distribute data on spam, phishing, cybercrimes and botnets, but also be a forum in which commercial mass e-mail senders and ISPs can work on trust. more

A Look at How the Internet Routes Around Damage: Measuring Global Effects of Storm Sandy

Hurricane Sandy caused major damage in both the Caribbean and the North-Eastern part of the USA. In an earlier article (RIPE Atlas - Superstorm Sandy) we showed data on 15 RIPE Atlas probes that are located in or near the affected areas in the USA. Most of these locations now appear to be back to normal round trip times to targets we monitor. But the effects of Hurricane Sandy were felt beyond the immediately affected area. more

Colloquium on Collisions: Expert Panelists to Select Papers, Award $50K First Prize

According to the Online Etymology Dictionary, the verb collide is derived from the Latin verb collidere, which means, literally, "to strike together": com- "together" + lædere "to strike, injure by striking." Combined instead with loquium, or "speaking," the com- prefix produces the Latin-derived noun colloquy: "a speaking together." So consider WPNC 14 - the upcoming namecollisions.net workshop - a colloquium on collisions: speaking together to keep name spaces from striking together. more

Automation for Physical Devices: the Holy Grail of Service Provisioning

Software-Defined Networking (SDN) and Network Functions Virtualization (NFV) are finally starting to pick up momentum. In the process, it is becoming clear that they are not the silver bullet originally advertised to be. While great for some use cases, emerging technologies like SDN and NFV have been primarily designed for virtual greenfield environments. Yet large service providers continue to run tons of physical network devices that are still managed manually. more

Mozilla, National Science Foundation Offer $2M Prize for a Decentralized Web

Mozilla and the National Science Foundation have announced a $2 million prize for ideas that decentralize the web; prizes will be available for both early-stage design concepts and fully-working prototypes. more

New Record Set in Ultra Fast Data Transmission

Scientists led by a team at Karlsruhe Institute of Technology (KIT) have broken a record for data transmission, sending data at 26Tb/s on a single laser beam over 50km. To put this into context, the researchers suggest that this is the equivalent of transferring the contents of 700 DVDs per second, or the entire collection of the Library of Congress in ten seconds.

Do We Really Need a New BGP?

From time to time, I run across (yet another) article about why Border Gateway Protocol (BGP) is so bad, and how it needs to be replaced. This one, for instance, is a recent example. It seems the easiest way to solve this problem is finding new people - ones who don't make mistakes - to work on BGP configuration, building IRR databases, and deciding what should be included in BGP? more

Advantage of Commercial Clouds vs. HPC for Scientific Research

The Department of Energy (DoE) recently came out with an excellent report, called the Magellan report, on the advantages and disadvantages of using commercial clouds versus in house High Performance Computers (HPC) for leading edge scientific research. The DoE probably supports the largest concentration of HPC facilities in the world. I agree with the report that for traditional applications such as computational chemistry, astrophysics, etc. will still need large HPC facilities. more

Back from RightsCon Manila: Trading Freedoms for Security?

In Asia -- a region that at various points in its recent history has been a hotbed for civil unrest, secessionist movements and political instability -- the line between national security and public interest can be difficult to draw. A session organised by the Internet Society at the recently held RightsCon Southeast Asia in Manila shed some light on the perceived trade-offs between national security objectives and digital rights, in particular freedom of expression and privacy. more

High Performance DNS Needs High Performance Security

There's been a lot of emphasis on DNS performance lately because faster DNS contributes directly to a better user experience. There's an interesting flipside to DNS performance though, higher performance DNS servers may be better targets for cache poisoning attacks. Faster servers give attackers more opportunities to insert fake entries into the DNS - speed can kill (or at least inflict a nasty wound!) so it's important to understand the security implications if you're looking to upgrade DNS performance. more
