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

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

How Is Russia Connected to the Wider Internet?

Speculation about Russia disconnecting or being disconnected from the wider Internet abounds. In this article, we look at the connectivity of the Russian Internet to the wider Internet and how this evolved around the Russian invasion of Ukraine and the related sanctions. 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

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

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

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

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

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

The ISP Industry: Concentrated or Diverse?

In August 2010, we looked at the growth in RIPE NCC membership and concluded that the number of new RIPE NCC members is still growing at an amazing pace, even during the recent economic downturn... This time we are looking at the different sizes of RIPE NCC members over time. It is often claimed that there is massive consolidation happening in the ISP community, especially in times of economic difficulties like in the early 2000s and now. We were curious to find out if this is really the case. 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

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

The Changing Mobile World

Today's Internet is undoubtedly the mobile Internet. Sales of all other forms of personal computers are in decline and the market focus is now squarely on tablets, "smart" phones and wearable peripherals. In 2014 these providers sold 1.5 billion such devices into the global consumer market, and doubtless 2015's numbers will be greater. Half of all Internet-visible devices are now mobile devices and they generate 75% of all access provider revenues. 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

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
