IPv6 represents new territory for most Internet stakeholders, and its rollout will introduce some unique security challenges.

Jeff Schmidt to Present Name Collision Management Framework at Research Workshop

I'm delighted to announce that the name collisions workshop this weekend will include Jeff Schmidt, CEO of JAS Global Advisors, presenting the Name Collision Occurrence Management Framework that his firm just released for public review. Jeff's presentation is one of several on the program announced by the program committee for the Workshop and Prize on Root Causes and Mitigations of Name Collisions (WPNC). more»

More Denial of Service Attacks

There are quite a lot of NTP-amplified denial of service attacks going around at the moment targeting tech and ecommerce companies, including some in the email space. What does NTP-amplifed mean? NTP is "Network Time Protocol" - it allows computers to set their clocks based on an accurate source, and keep them accurate. It's very widely used - OS X and Windows desktops typically use it by default, and most servers should have it running. more»

Papers Now Available Publicly for W3C/IAB "Strengthening the Internet" Workshop

Want to read a wide range of views on how to strengthen the security and privacy of the Internet? Interested to hear how some of the leaders of the open standards world think we can make the Internet more secure? As I wrote about previously here on CircleID, the W3C and the Internet Architecture Board (IAB) are jointly sponsoring a workshop on "Strengthening The Internet" (STRINT) on February 28 and March 1 in London just prior to the IETF 89 meeting happening all next week. more»

Keynote Speaker for Name Collisions Workshop: Bruce Schneier

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»

Mind the Step(-function): Are We Really Less Secure Than We Were a Year Ago?

In January 1995, the RFC Editor published RFC 1752: "The Recommendation for the IP Next Generation Protocol"... The Internet is a security officer's nightmare -- so much openness, so easy to capture packet traffic (and/or spoof it!) and send all manner of unwanted traffic. It was built as a research network, hosted by institutes that were 1/ professionally responsible and 2/ interested in working together collegially. So, in the 19 years since the publication of that statement, have we really failed to address the stated goal? more»

Namecoin Decentralized DNS Research

The holidays open up a block of time to catch up on "I meant to read that" bookmarks, RSS feeds, and all the favorited and forgotten tweets. I made it through 50 before a NormanShark blog post kicked off a research project. The analysts found a malware sample which was using .bit domains in their communications infrastructure, but .bit ... what is that? .bit is a TLD operating outside of ICANN. Some would say they are TLD squatting, but I leave that opinion up to the reader. more»

More Problems Crop Up With Universal Acceptance of Top Level Domains

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»

Extreme Vulnerability at the Edge of the Internet - A Fresh New Universal Human-Rights Problem

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»

Colloquium on Collisions: Expert Panelists to Select Papers, Award $50K First Prize

According to the Online Etymology Dictionary, the verb collide is derived from the Latin verb collidere, which means, literally, "to strike together": com- "together" + l├Ždere "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 workshop - a colloquium on collisions: speaking together to keep name spaces from striking together. more»

Securing the Core

BGP. Border Gateway Protocol. The de-facto standard routing protocol of the Internet. The nervous system of the Internet. I don't think I can overstate the importance, the criticality of BGP to the operation of the modern Internet. BGP is the glue that holds the Internet together at its core. And like so many integral pieces of the Internet, it, too, is designed and built on the principle of trust... The folks who operate the individual networks that make up the Internet are generally interested in keeping the Internet operating, in keeping the packets flowing. And they do a great job, for the most part. more»
