Watching North Korea’s Internet Connectivity Go Up and Down Via Twitter

One thing I enjoy about following Dyn Research (formerly Renesys) on Twitter is that they provide quite interesting graphics and charts about Internet outages. They've been tracking North Korea's Internet access quite closely over the past week and their tweets have been quite enlightening. Back on December 22, for instance, DynResearch tweeted a chart showing a 9-hour, 31-minute outage... more

Do I need DDoS protection? A Realistic Look at the Decision Process

There has been a recent spate of well publicised Distributed Denial of Service (DDoS) attacks that bring websites down and render them useless, including Evernote and most recently Feedly. In light of this, here are some comments and tips to help companies evaluate and prepare not to be held for ransom or suffer lost reputation and sales as a result. more

Overcoming Cloud Storage Security Concerns: 7 Key Steps

According to a 2013 TwinStrata survey, 46 percent of organizations use cloud storage services and 38 percent plan to adopt this technology in the near future. Cloud storage capacity demands are increasing 40 to 60 percent year-over-year, while storage density lags behind at 20 percent. The result? More data, growing demands for space and increasing security concerns. How do enterprises overcome cloud storage security challenges? more

Operational Challenges When Implementing DNSSEC

As a reader of this article, you are probably familiar with the DNS cache poisoning techniques discovered a few years ago. And you have most likely heard that DNSSEC is the long term cure. But you might not know exactly what challenges are involved with DNSSEC and what experience the early adopters have gathered and documented. Perhaps you waited with our own rollout until you could gather more documentation over the operational experience when rolling out DNSSEC. This article summarizes authors' experiences and learnings from implementing the technology in production environments as well as discusses associated operational issues. more

Securing Weak Links in Supply Chain Attacks

We've all heard the term, "you're only as strong as your weakest link." Whether talking about a tug of war on the playground, a sports team, or a business, this rings as true as ever. Every business relies on a series of suppliers and vendors -- be it the dairy farm supplying milk to the multinational food manufacturer or the payment systems that retailers use. These links form supply chains that every business, large and small, deals with. There is simply no way around it. more

Notes from NANOG 63

The following is a selected summary of the recent NANOG 63 meeting, held in early February, with some personal views and opinions thrown in! ...One view of the IETF's positioning is that as a technology standardisation venue, the immediate circle of engagement in IETF activities is the producers of equipment and applications, and the common objective is interoperability. more

Emerging Markets Tech Watch 2012

2011 has been a significant year for the technology sector globally. Information technology is touching more people in more ways than ever before. Developed markets will be considering a 2012 in which business innovation, competitiveness, and service differentiation are built on ubiquitous broadband, cloud computing, smarter mobile computing, and an increasing plethora of Internet-connected devices. By contrast, securing the technology future for developing markets demands that attention be placed on more fundamental issues. more

DNS Abuse Definition: Attributes of Mitigation

A substantial amount of DNS community discussion on the topic of DNS Abuse is focused on defining what is or is not DNS Abuse. The definition adopted by ICANN contracted parties, as well as the DNS Abuse Institute, is straightforward: DNS Abuse is malware, botnets, pharming, phishing, and spam where it's a vehicle for the preceding harms. There is, of course, some fuzziness on the margins, where technical harms are also using content. more

60 Minutes Investigates Cybersecurity and the Reality of Sabotaging Critical Infrastructure

CBS's 60 Minutes aired a special report last night investigating how hackers can get into the computer systems that run crucial elements of the world's infrastructure, such as the power grids, water works or even a nation's military arsenal. From the report: "At the Sandia National Laboratories, Department of Energy security specialists like John Mulder try to hack into computer systems of power and water companies, and other sensitive targets in order to figure out the best way to sabotage them. It's all done with the companies' permission in order to identify vulnerabilities. In one test, they simulated how they could have destroyed an oil refinery by sending out code that caused a crucial component to overheat." more

It’s Time to Rethink Outage Reports

Much has been said about the criticality of the small coterie of large-scale content distribution platforms and their critical role in today's Internet. These days when one of the small set of core content platforms experiences a service outage, then it's mainstream news, as we saw in June of this year with outages reported in both Fastly and Akamai. In the case of Akamai, the June outage impacted three of Australia's largest banks, their national postal service, the country's reserve bank, and one airline... more

NANOG 65 Report

NANOG 65 was once again your typical NANOG meeting: a set of operators, vendors, researchers and others for 3 days, this time in Montreal in October. Here's my impressions of the meeting... The opening keynote was from Jack Waters from Level 3, which looked back over the past 25 years of the Internet, was interesting to me in its reference to the "Kingsbury Letter". more

NSA, Prism and Internet Exchange Points in Canada

As the operator of the registry for the .CA top-level domain and the domain name system (DNS) infrastructure that supports it, I am uncomfortable, though not surprised, with the knowledge that a government is monitoring the activities of Internet users. And while recent reports about the National Security Agency's top-secret PRISM program actively monitoring Internet users in the United States and (by default) citizens of other countries - Canada included - are on the front page of newspapers around the world, Internet surveillance is not exactly new. more

Anti-Spoofing, BCP 38, and the Tragedy of the Commons

In the seminal 1968 paper "The Tragedy of the Commons" , Garrett Hardin introduced the world to an idea which eventually grew into a household phrase. In this blog article I will explore whether Hardin's tragedy applies to anti-spoofing and Distributed Denial of Service (DDoS) attacks in the Internet, or not... Hardin was a biologist and ecologist by trade, so he explains "The Tragedy of the Commons" using a field, cattle and herdsmen. more
