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

Addressing 2013 - That Was the Year That Was

Time for another annual roundup from the world of IP addresses. What happened in 2013 and what is likely to happen in 2014? This is an update to the reports prepared at the same time in previous years, so let's see what has changed in the past 12 months in addressing the Internet, and look at how IP address allocation information can inform us of the changing nature of the network itself. 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

Google’s Acquisition of Nest and Smart Homes

Google's $3.2 billion acquisition of high-tech thermostat and smoke-detector maker Nest Labs will allow the company to further infiltrate people's lives, not just via their smartphones but now also via a range of home appliances. It is a logical development for the digital media giant and based on their record of innovation we can expect a range of interesting products and services, also known as machine-to-machine (M2M) communication and the Internet of Things (IoT), to enter this market. more

W3C/IAB “Strengthening the Internet” Workshop: Deadline Monday to Submit Position Papers

How can the open standards organizations of the IETF and W3C "strengthen the Internet" against large-scale pervasive monitoring? That is the topic up for discussion at the "Strengthening the Internet Against Pervasive Monitoring (STRINT)" workshop planned for February 28 and March 1, 2014, and jointly sponsored by the Internet Architecture Board (IAB) and the W3C. The workshop is by invitation-only and has a deadline of Monday, January 20, 2014 (by 11:59 UTC) for submission of either position papers or Internet drafts. more

21 Experts Give Their 2014 Predictions on Internet Performance

Last week, we started an email thread (old school!) amongst a large group of our tech leadership and thought leaders from all aspects of web traffic management and message management. There was a simple question we wanted to know in a few sentences or less: "In 2014, what do you think the big trends will be with Internet performance?" What follows are 21 very unique, and some very similar, answers. Without a doubt, there are challenges ahead for the Internet as we know it, but the rewards for accomplishing goals are massive. more

Network Outages Costing Mobile Operators $15B Annually

Sarah Reedy reporting in LightRading: Mobile operators suffer from an average of five network outages or degradations that impact subscribers each year, costing them around $15 billion annually, according to new Heavy Reading research. Put another way, that's about one outage every other month. More than 80 percent of those outages affect just one or a subset of networks or services. more

The Christmas Goat and IPv6 (Year 4)

This year, 2013, I got 24 days of IPv6 and DNSSEC measurements. All in all it created 15GB logs with more than 62 million rows. On the 21st of December, early in the morning, the goat was "traditionally" burnt down, however this year with one exception. Via the Swedish newspaper Expressen the arsonists anonymously took the blame and also filmed their own act. more

Internet Governance Outlook 2014: Good News, Bad News, No News?

What does the crystal ball say for the Internet in 2014? Here are three scenarios for what could happen with the global Internet Governance Eco-System in the coming 12 months... In the worst case scenario the Internet gets more and more fragmented and re-nationalized. A growing number of governments start to define a "national Internet segment" and develop policies to surveil, censor and control access to and use of the Internet. National firewalls will separate the "domestic Internet" from the global Internet and an exit and entrance regime into networks is introduced where users need passwords, handed out by governmental authorities on an annual basis, to go from one domain to another... 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

2014 M3AAWG Mary Litynski Award Nominations Now Being Accepted

In 2010 the Messaging, Malware and Mobile Anti-Abuse Working Group (M³AAWG) and the Internet industry as a whole lost a great friend and supporter, Mary Litynski. Her dedication, excellence, perseverance and tireless work behind the scenes of M³AAWG helped make the organization the success that it is today. Through this award, M³AAWG seeks to bring attention to the remarkable work that is done far from the public eye over a significant period of time... more

IP Addresses and Traceback

This is an informal description the evolution of a particular area of network forensic activity, namely that of traceback. This activity typically involves using data recorded at one end of a network transaction, and using various logs and registration records to identify the other party to the transaction. Here we'll look at the impact that IPv4 address exhaustion and IPv6 transition has had on this activity, and also note, as we explore this space, the changing role of IP addresses within the IP protocol architecture. more

Watch Live - What Does “Success” For IPv6 Look Like? (Briefing Panel on Nov 5)

Now that IPv6 deployment is happening in major networks around the world, the question becomes -- what does "success" look like for IPv6? How much IPv6 traffic is "enough"? What are major milestones we should be tracking in IPv6 deployment? What is next for IPv6? more

Highlights from SCTE Cable-Tec EXPO

As a product manager and engineer, I really enjoy attending the technology-oriented Cable-Tec Expo each year. It has a stronger technology focus than many other industry trade shows and it's always a good opportunity to talk to the engineering teams from all of the operators and vendors. more

DNS Tunneling: Is It a Security Threat?

DNS tunneling -- the ability to encode the data of other programs or protocols in DNS queries and responses -- has been a concern since the late 1990s. If you don't follow DNS closely, however, DNS tunneling likely isn't an issue you would be familiar with. Originally, DNS tunneling was designed simply to bypass the captive portals of Wi-Fi providers, but as with many things on the Web it can be used for nefarious purposes. For many organizations, tunneling isn't even a known suspect and therefore a significant security risk. more
