Part 2 of 5: Internet Infrastructure: Stability at the Core, Innovation at the Edge
For nearly all communications on today’s internet, domain names play a crucial role in providing stable navigation anchors for accessing information in a predictable and safe manner, irrespective of where you’re located or the type of device or network connection you’re using. The underpinnings of this access are made possible by the Domain Name System (DNS), a behind the scenes system that maps human-readable mnemonic names (e.g.,www.Verisign.com) to machine-usable internet addresses (e.g., 69.58.187.40). The DNS is on the cusp of expanding profoundly in places where it’s otherwise been stable for decades and absent some explicit action may do so in a very dangerous manner.
Part 1 of 5: Introduction: New gTLD Security and Stability Considerations
Verisign recently published a technical report on new generic top-level domain (gTLD) security and stability considerations. The initial objective of the report was to assess for Verisign’s senior management our own operational preparedness for new gTLDs, as both a Registry Service Provider for approximately 200 strings, as well as a direct applicant for 14 new gTLDs (including 12 internationalized domain name (IDN) transliterations of .com and .net). The goal was to help ensure our teams, infrastructure and processes are prepared for the pilot and general pre-delegation testing (PDT) exercises, various bits of which are underway, and the subsequent production delegations and launch of new gTLDs shortly thereafter.
Cloud-Based DDoS Protection and Managed DNS Services Helping to Increase Operational Efficiency and Thwart Large Attacks
As businesses continue to move critical operations online, distributed denial of service (DDoS) attacks are increasing in frequency, sophistication and range of targets. In a 2011 Verisign study, 63 percent of respondents reported experiencing at least one attack that year, while 51 percent reported revenue loss as a result of downtime from the attack. Those numbers are undoubtedly higher today as the size, frequency and complexity of DDoS attacks continue to grow. Mitigation against these types of attacks is challenging and generally requires layered solutions across data centers and the cloud management. The success of these attacks and their ability to damage a company’s infrastructure, revenue and reputation is indicative that many IT managers still haven’t found the right protection formula to proactively mitigate them.
Improving the Internet, In Person and Online
As much as the world has become more connected, so that people across the world can collaborate online at any hour of the day (even in the midst of weather events like Sandy), there’s still an important role for conferences that bring people together in person at a specific time and place.
I’ve been reminded of the value of this technical “networking” as I’ve attended some key events related to my own work in recent weeks.
In mid-October, I spent some time at the ICANN 45 meeting in Toronto, the triannual focal point for industry work on domain names (as well as IP “numbers”, the second “N”). Pat Kane, senior vice president and general manager of Verisign’s Naming Services, describes his experiences at this important series as exemplifying “hard work and collaboration.” Good technical consensus, as I’ve learned through my past years in industry forums in cryptography and security, starts with trust. The many introductions and conversations that I enjoyed throughout my visit built on this value.
The Promise of a Better Connected Digital World
Earlier this year, Verisign announced its 2012 Internet Infrastructure Grant program, which called for proposals for basic research with “potential to improve the availability and security of internet access in all parts of the world.” Two proposals would be selected based on criteria of relevance, innovation, feasibility, and overall quality.
It’s my honor now to announce that the program’s distinguished judging panel has reached its decisions. The awards will go to:
- Converged, Secure Mobile Communication Support Through Infrastructure-opportunistic, DHT-based Network Services led by Prof. Z. Morley Mao, University of Michigan (United States) and Prof. Cui Yong, Tsinghua University (China)
- Downscaling Entity Registries for Poorly-Connected Environments led by Prof. Dr. Philippe Cudré-Mauroux, Director, eXascale Infolab, University of Fribourg (Switzerland) and Dr. Christophe Guéret, Vrije Universiteit Amsterdam (The Netherlands)
Do We Need An IPv6 Flag Day?
In recent interviews about World IPv6 Launch I’ve been asked by several different people whether or not I think there needs to be some kind of a “Flag Day” on which the world all together switches from Internet Protocol version 4 (IPv4) to the version 6 (IPv6).
I don’t think a flag day is needed. World IPv6 Launch is just the right thing.
It’s worth looking at some previous flag-type days to get a better sense of why.
Research Grants for Building Virtual Neighborhoods
One of the highlights of my first seven months at Verisign was attending the annual meeting of the Internet Governance Forum(IGF) in Nairobi, Kenya last September. I had the pleasure of serving with industry, policy and technical leaders from around the world on several panels concerned with how to manage the internet as a shared and connected global resource. It was my first trip to Africa, and similar to my experience at each of the other new continents I’ve visited over the course of my career, what once seemed so far away became much closer to home – especially as I sat in the conference room and tweeted and emailed over the wireless network!
Attending IGF was a strong reminder that the world has become so much more connected, with internet access a huge enabler of the global economy. People are learning, companies are forming, and society is changing in new ways as a result of an interconnectedness that puts Kenya and every other country in the same, virtual neighborhood.
Connecting With Verisign: Seven Months In
As a technology leader whose career objective is to help build a connected digital world, it’s hard for me to envision a better place to be at this time in internet history than Verisign.
That’s what I needed to be convinced of earlier this year when I decided to leave a good job with great people at another leading IT company to become Verisign’s CTO. Seven months later, I haven’t been disappointed.
