Military Asserts Rights to Return Cyber Attacks

The Washington Post had a good article up yesterday capturing comments issued by the United States military that it has the right to return fire when it comes to cyber attacks... This is an interesting point of view, and it extends from the United States's policy that if it is attacked using conventional weapons, it reserves the right to counter respond in kind. This has been a long accept precept governing US foreign military policy for generations. Yet cyber attacks are different for a couple of reasons... more

An Update on Securing BGP from IETF 102

One way or another we've been working on various aspects of securing the Internet's inter-domain routing system for many years. I recall presentations dating back to the late '90's that point vaguely to using some form of a digital signature on BGP updates that would allow a BGP speaker to assure themselves as to the veracity of a route advertisement. more

Routing Without Rumor: Securing the Internet’s Routing System

The Domain Name System has provided the fundamental service of mapping internet names to addresses from almost the earliest days of the internet’s history. Billions of internet-connected devices use DNS continuously to look up Internet Protocol addresses of the named resources they want to connect to - for instance, a website such as blog.verisign.com. Once a device has the resource’s address, it can then communicate with the resource using the internet’s routing system. more

ARIN and Antigua & Barbuda Government to Hold Workshop on Internet Resilience

The American Registry for Internet Numbers (ARIN) is collaborating with the government of Antigua and Barbuda to strengthen the technical capacity of local network operators. ARIN is one of five registries responsible for coordinating Internet number resources worldwide. Its service area includes Canada, the United States, and several Caribbean countries. The collaboration with the Antigua and Barbuda government comes as part of a broader thrust by ARIN to support the development of the Internet across the region. more

Recommendations for Adding Cybersecurity Intelligence to the Smart Grid

Over the last few years, there has been an increased effort to modernize the U.S. electric grid. Building a "Smart Grid" has been central in the effort to help utilities better manage their resources, minimize power outages and reduce energy consumption. However, adding more electronic devices and sensors to the grid's network has made it a prime target of cyberattacks, like Distributed Denial of Service (DDoS) attacks, which if successful, could cause wide-spread disruption of services affecting many other sectors. more

Going Dark: How the Increasingly Dark Network Is Creating Some Pretty Ugly Choices for Site Security Administrators

I'd like to reflect on a presentation by Dr. Paul Vixie at the October 2022 meeting of the North American Network Operators Group (NANOG) on the topic of the shift to pervasive encryption of application transactions on the Internet today. There is a view out there that any useful public communications medium needs to safeguard the privacy and integrity of the communications that it carries.  more

45th Anniversary of the First Message Between ARPAnet Computers

Given that CircleID is about "Internet Infrastructure" it would be remiss if there wasn't a mention here that October 29, 2014, was the 45th anniversary of the moment when the first message was sent between two ARPAnet computers located at UCLA and the Stanford Research Institute (SRI). That moment was chronicled well this year by Matt Novak writing on Gizmodo's Paleofuture, complete with photos of the original logs and more. more

Is Secured Routing a Market Failure?

The Internet represents a threshold moment for the communications realm in many ways. It altered the immediate end client of the network service from humans to computers. It changed the communications model from synchronized end-to-end service to asynchronous and from virtual circuits to packet switching. At the same time, there were a set of sweeping changes in the public communications framework... more

Cisco Collaboration Summit - Where Unified Communications Could Be Going

This year's Cisco Collaboration Summit was a step up from last year, and I say that for good reason. Last year's event was good -- all of Cisco's events are good -- but the venue was too small and it took away from the messaging. For 2010, Cisco went out of town to the classy and classic Arizona Biltmore in Phoenix. They don't build them like this anymore, and to me, this setting did far more justice for what Cisco has to say about collaboration. more

RIPE at 59!

RIPE, or Réseaux IP Européens, is a collaborative forum open to all parties interested in wide area IP networks in Europe and beyond... RIPE has been a feature of the European Internet landscape for some twenty years now, and it continues to be a progressive and engaged forum. These days RIPE meets twice a year, and the most recent meeting was held at Lisbon, Portugal, from the 5th to the 9th of October 2009. In this column I'd like to share some of my impressions of this meeting. more

Disruptive Google Fiber Is Shaking up the Telco World

The Google Fiber project is receiving international attention. This in itself is a good thing, since it brings the benefits of high-speed FttH infrastructure to the attention of large numbers of people in business and government who will not have to deal with such developments on a regular basis... At the same time we have to look at Google Fiber from the point of view of operating in the American regulatory environment. Yes, we can all learn from its disruptive model, and particularly when the results of the more innovative elements of the services begin to kick in; but for other reasons there is no way that this model can be replicated elsewhere. more

Name Collisions II - A Call for Research

This post is a heads up to all uber-geeks about a terrific research initiative to try to figure out causes and mitigation of name-collision risk. There's a $50,000 prize for the first-place paper, a $25,000 prize for the second place paper and up to five $10,000 prizes for third-place papers. That kind of money could buy a lot of toys, my peepul. And the presentation of those papers will be in London -- my favorite town for curry this side of India. Interested? Read on. more

Cloud Computing’s Concealed Complexity

James Urquhart claims Cloud is complex - deal with it, adding that "If you are looking to cloud computing to simplify your IT environment, I'm afraid I have bad news for you" and citing his earlier CNET post drawing analogies to a recent flash crash. Cloud computing systems are complex, in the same way that nuclear power stations are complex - they also have catastrophic failure modes... more

Doug Madory Reports on Shutting Down the BGP Hijack Factory

A lengthy email to the NANOG mailing list last month concerning suspicious routing activities of a company called Bitcanal initiated a concerted effort to kick a bad actor off the Internet. more

From Net Neutrality to Seizing Opportunity

Network neutrality is important in the context of assuring the opportunity to innovate in how we communicate and connect. We can't define it in terms of specific outcomes but rather in terms of what we enable. The Internet is just one example of what we can do when given the opportunity to use software to fashion our own solutions... I thought about this more when I found myself in my hospital room (after knee surgery) unable to open and close the shades by myself. But yet I could control the lights in my house! more
