In Internet Draft draft-lee-dnsop-scalingroot-00.txt, I described with my coauthors a method of distributing the task of providing DNS Root Name Service both globally and universally. In this article I will explain the sense of the proposal in a voice meant to be understood by a policy-making audience who may in many cases be less technically adept than the IETF DNSOP Working Group for whom the scalingroot-00 draft was crafted. I will also apologize for a controversial observation concerning the addition of new root name servers... more
After the botched burglary at the Watergate Apartments, every scam and scandal that hit the headlines became a 'gate' -- Irangate, Contragate, you name it. The Heartbleed bug is possibly the closest thing to Watergate that this generation of computer security had seen till the past few days -- an exploit in a component that is "just there" -- something you utterly rely on to be there and perform its duties, and give very little thought to how secure (or rather, insecure) it might be. So, fittingly, every such catastrophic bug in an ubiquitous component is now a 'bleed'. more
It has been another busy quarter for the team that works on our DDoS Protection Services here at Verisign. As detailed in the recent release of our Q2 2014 DDoS Trends Report, from April to June of this year, we not only saw a jump in frequency and size of attacks against our customers, we witnessed the largest DDoS attack we've ever observed and mitigated -- an attack over 300 Gbps against one of our Media and Entertainment customers. more
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
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
I will first begin this post by emphasizing that this article is entirely my personal viewpoint and not to be considered as endorsed by or a viewpoint of my employer or any other organization that I am affiliated with. Neither is this to be considered an indictment of the sterling work (which I personally value very highly) that several people in Microsoft are doing against cybercrime. Microsoft's takedown of 3322.org to disrupt the Nitol botnet is partial and will, at best, have a temporary effect on the botnet itself... more
Until now, the criminals behind malware and phishing have had only 22 generic top-level domain names (TLDs) to abuse -- names like .com, .net or .org. But with hundreds of new TLDs entering the marketplace, e.g. .buzz, .email, and .shop, there are many more targets than ever... What can attackers do with domain names? more
In a video interview conducted during the NSCS ONE conference, Paul Vixie CEO of Farsight Security further discusses the topic of his presentation titled: "Defective by Design -- How the Internet's Openness is Slowly Poisoning Us". more
The first question I often get when talking to IT Service providers on ISO 27001 certification is: "How much does it cost to get it?" I like to reply with a question: "how much does it cost when you don't have it?" The answer to the first question is easy, the answer to the second one is more complicated. As a financial I am interested in the business case. If the cost of not having an ISO 27001 certification is higher than the cost of getting and maintaining one, you can actually make a profitable investment by getting certified. more
Today the e-mail faerie brought news of the release of BIND9 9.10.0 which can be downloaded from here. BIND9 is the most popular name server on the Internet and has been ever since taking that title away from BIND8 which had a few years earlier taken it from BIND4. I used to work on BIND, and I founded ISC, the home of BIND, and even though I left ISC in July 2013 to launch a commercial security startup company, I remain a fan of both ISC and BIND. more
Keynote speaker, and noted security industry commentator, Bruce Schneier (Co3 Systems ) set the tone for the two days with a discussion on how humans name things and the shortcomings of computers in doing the same. Names require context, he observed, and "computers are really bad at this" because "everything defaults to global." Referring to the potential that new gTLDs could conflict with internal names in installed systems, he commented, "It would be great if we could go back 20 years and say 'Don't do that'," but concluded that policymakers have to work with DNS the way it is today. more
There may still be a few security practitioners working in the field who didn't have a copy of Bruce Schneier's Applied Cryptography on their bookshelf the day they started their careers. Bruce's practical guide to cryptographic algorithms, key management techniques and security protocols, first published in 1993, was a landmark volume for the newly emerging field, and has been a reference to developers ever since. more
By design, the Internet core is stupid, and the edge is smart. This design decision has enabled the Internet's wildcat growth, since without complexity the core can grow at the speed of demand. On the downside, the decision to put all smartness at the edge means we're at the mercy of scale when it comes to the quality of the Internet's aggregate traffic load. Not all device and software builders have the skills - and the quality assurance budgets - that something the size of the Internet deserves. more
I've often found truth in the famous George Santayana quote, "Those that cannot remember the past are doomed to repeat it." That's an apt warning for what is currently happening - again - with the hundreds of new generic Top Level Domains (gTLDs) that are launching ... and failing to work as expected on the Internet. First, a quick refresher: As most CircleID readers know, in the early 2000s, seven new gTLDs were launched: .AERO, .BIZ, .COOP, .INFO, .MUSEUM, .NAME and .PRO. Aside from Country Code TLDs (ccTLDs), these were the first top-level changes to the DNS since the early days of the Internet. more
According to the Online Etymology Dictionary, the verb collide is derived from the Latin verb collidere, which means, literally, "to strike together": com- "together" + lædere "to strike, injure by striking." Combined instead with loquium, or "speaking," the com- prefix produces the Latin-derived noun colloquy: "a speaking together." So consider WPNC 14 - the upcoming namecollisions.net workshop - a colloquium on collisions: speaking together to keep name spaces from striking together. more
