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

Senate Judiciary Committee Hearing on Botnet Takedowns (July 15, 2014)

The background is of course quite interesting, given how soon it has followed Microsoft's seizure of several domains belonging to Dynamic DNS provider no-ip.com for alleged complicity in hosting trojan RAT gangs, a couple of days after which the domains were subsequently returned -- without public comment -- to Vitalwerks, the operator of No-IP. This is by no means a new tactic for Microsoft, who has carried out successful seizures of various domains over the past two or three years. more

Memo to John Markoff: There are No “Do Overs” in History

Think for a moment of the enduring legacy of African slavery in America. Think of the way it tainted this country's culture and politics; think of the bloody Civil War, the ghettos... What if we could roll back the clock and ensure that our society was "designed" so that slavery was never permitted and never happened? ... But what if I told you that my computer science lab was working on a "new Internet" that would solve all the terrible security and privacy problems of the existing one? Would you find this claim more credible than a proposed retroactive solution to the problem of slavery? more

Denmark Encounters Largest Cyber Attack on Its Critical Infrastructure to Date

Denmark experienced its largest-ever cyberattack in May, targeting the nation's critical infrastructure. SektorCERT, the Danish cybersecurity authority, reported breaches in 22 companies within days. Many resorted to 'island mode,' isolating themselves from the internet to contain the threat. more

2012 Security Predictions: APT’s, Mobile Malware and Botnet Takedowns

As the weeks remaining in 2011 dwindle and 2012 peaks out from behind the last page of the calendar, it must once again be that time of year for purposeful reflection and prediction. Or is that navel gazing and star gazing? At the highest level of navel gazing you could probably sum up 2011 with one word -- "More"... But let's put that aside for now. What does 2012 hold in stall for us? more

Nameserver Operators Need the Ability to “Disavow” Domains

Yesterday's DDoS attack against DNSimple brought to light a longstanding need for DNS nameserver operators to have an ability to unilaterally repudiate domains from their nameservers. The domains under attack started off on DNSMadeEasy, migrated off to DNSimple and took up residence there for about 12 hours, causing a lot of grief to DNSimple and their downstream customers. 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

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

Ensuring Maximum Resilience to the DNS?

Yesterday CommunityDNS noticed a sudden, heavy spike in traffic through its Anycast node in Hong Kong. While comfortably processing queries at 863,000 queries per second for close to 2 hours the occurrence was undeniable. While we can't say the increase in traffic was specifically due to DDoS, its sudden increase is suspicious and reminds us that DDoS is still a popular tool used by the malicious community. 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

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

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
