Title II Will Have Little Effect on Telecom Developments in The USA

We now know what direction the FCC will take in reorganising the American telecoms market. For many years I have mentioned the rather bizarre situation in that country wherein broadband is not seen as a telecoms service but rather as an internet service, which is itself classified as providing content. Thanks to extensive lobbying from among the telcos (who also refer to themselves as ISPs) in the early days of the internet, back in the 1990s, the FCC accepted their unbelievable proposals. As a result, over the last 20 years or so the USA's telecom market has changed from being one of the most competitive among developed economies to what it is now: a market with hardly any fixed telecoms competition at all. more

Top Six IT Trends Impacting Business Networks

For decades, IT followed business. Even the development of the World Wide Web didn't move this development much beyond the four walls of corporate offices -- outside connections were essential but never informed the growth of business-critical technology. Now the growth of public clouds, enterprise-grade social networking and mobile device use in the workforce is creating a new paradigm, one where business networks are reactive to IT trends -- here are six that are set to impact companies this year. 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

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

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

Understanding the Modern DDoS Threat

The breadth of cyber threats that an organization must engage with and combat seemingly change on a daily basis. Each new technology, vulnerability or exploit vector results in a new threat that must be protected against. Meanwhile some forms of attack never appear to age -- they remain a threat to business continuity despite years of advances in defensive strategy. One particularly insidious and never-ending threat is that of the Distributed Denial of Service (DDoS) attack. 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

Connectivity Starts at Home

Today's Internet is just one application of the powerful idea of best-efforts connectivity. The home router (NAT) decouples the connectivity within the home from the larger internet, enabling innovation that leverages the Internet without being limited by it. Connectivity starts at home. Your computers and devices all interconnect locally. In a sense, the larger Internet is just one more connected device. You are free to innovate and experiment without asking a provider's permission. 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

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

Scaling the Root of the DNS

The DNS is a remarkably simple system. You send it queries, and you get back answers. Within the system, you see exactly the same simplicity: The DNS resolver that receives your query may not know the answer, so it, in turn, will send queries deeper into the system and collects the answers. The query and response process is the same, applied recursively. Simple. However, the DNS is simple in the same way that Chess or Go are simple... more

Could SNET Become Cuba’s Guifi.net?

In an earlier post, I described Havana's community network, SNET, and wondered what it could become if the government and ETECSA were willing to legitimatize and support it. Spain's Guifi.net provides a possible answer to that question. Guifi.net is said to be the largest community network in the world. It began in 2004 and has grown to have 34,165 nodes online with 16,758 planned, 407 building, 612 testing and 4,043 inactive. more

The Case for Hot Swappable Nameservers

Earlier this week we announced our "Proactive Nameservers", which is just marketing speak for what it really is: hot swappable nameservers or nameserver fail over. What is it? ... It's basically what every webmaster, IT department and CTO wishes they had set up before... more

Will Cisco Make a Comeback in Cuba?

Is the recently announced Cisco Networking Academy at the Universidad de Ciencias Informáticas a belated drop in the bucket or the first step in a significant opening? Cisco dominated the infrastructure equipment market in Cuba and elsewhere during the early days of the Internet, but Huawei replaced them in Cuba... What does this mean? It might be a belated drop in the bucket. UCI has only 19 trained CNA instructors while the CNA curriculum is being taught by over 20,000 instructors at over 10,000 institutions. more

Syria Disconnects From The Internet

This morning brought word that all Internet connections into Syria had been severed. Internet monitoring firm Renesys was among the first to report the news in a blog post that they have continued to update. That news was subsequently confirmed by other sites and services... Multiple reports indicate that all Internet, cell phone and landline connections to all or most of the country have been severed. more
