Vint Cerf Receives IEEE Medal of Honor

Vinton Cerf, widely known as the "Father of the Internet," has been awarded the IEEE Medal of Honor in 2023 for his contributions to the development of the Internet architecture and for his leadership in its growth as a critical infrastructure for society. more

The State of RPKI as We Enter 2022

Resource Public Key Infrastructure (RPKI) is a method to secure internet routing traffic by cryptographically verifying routes. As we begin 2022, we look back at 2021 and see how the year saw another significant step towards its adoption. High-profile issues with the old trust-based model of Border Gateway Protocol, designed several decades ago, have shown the continued importance of protecting popular networks from mistakes or hackers. more

Routing Security - Getting Better, But No Reason to Rest!

In January 2018, I looked back at 2017 to figure out how routing security looked globally and on a country level. Using the same metrics and methodology, I've recently taken a look at 2018 to see if we're making improvements. The good news is, it seems like the routing system is doing better! But there is still much work to be done. Using BGPStream.com, a great public service providing information about suspicious events in the routing system, I analyzed the number of incidents... more

IoT From a Network Perspective: Learning to Navigate the New Realms

Let's play the analogy game. The Internet of Things (IoT) is probably going end up being like... a box of chocolates, because you never do know what you are going to get? a big bowl of spaghetti with a serious lack of meatballs? Whatever it is, the IoT should have network folks worried about security. Of course, there is the problem of IoT devices being attached to random places on the network, exfiltrating personal data back to a cloud server you don't know anything about. more

Why Over Compliance With Sanctions at Internet Infrastructure Level Can Have Devastating Effects on Ordinary People

On Friday, Mykhailo Fedorov, Ukraine's digital transformation minister, asked Cloudflare and Amazon to stop serving Russian web resources and protecting Russian services. He said in a tweet that Ukraine was "calling on Amazon to stop providing cloud services in Russia." He also said that "Cloudflare should not protect Russian web resources while their tanks and missiles attack our kindergartens." more

Three Generations of Cuban WiFi Hotspot Sharing

As soon as ETECSA began installing public access WiFi hotspots, black market resellers began sharing connections. They would connect a laptop to an ETECSA account then use pirated copies of Connectify, a connection sharing program running on the laptop, to create small WiFi hotspots of their own. At the time, ETECSA charged 2 CUC per hour online (two day's pay for many Cubans) and the re-sellers typically charged 1 CUC per hour. They broke even with two users and made a profit with more. more

Connectivity as a Vital Consumer Service

Having Comcast et al provide Internet connectivity is like having your barber do surgery because he knows how to use a knife. I was reminded of this when my Comcast connection failed. This is part of the larger topic of consumerization. In the past, we were happy to have products that worked at all. I grew up in the world of consumer products and got my start in software building online services meant for use by non-experts. more

Bespoke Processors and the Future of Networks

As I spend a lot of time on Oak Island (not the one on television, the other one), I tend to notice some of those trivial things in life. For instance, when the tide is pretty close to all the way in, it probably is not going to come in much longer; rather, it is likely to start going back out soon. If you spend any time around clocks with pendulums, you might have noticed the same thing; the maximum point at which the pendulum swings is the point where it also begins swinging back. more

Broadband Carrier Quandary: Exploit Bandwidth Scarcity, or Reduce It?

Comcast enhanced the value position of its broadband subscriptions by increasing the monthly data allowance to 1 Terrabyte (1000 Gigabytes). See Comcast Announcement. As an independent, unsponsored researcher, I can say "Thank You Comcast" without adverse consequences and only a bit of irony. This company does much to displease, but an expanded data allowance offers a winning proposition. more

DDoS Awareness Day - Oct 23, Register Today for Live Virtual Event

In support of National Cyber Security Awareness Month, DDoS Awareness Day is a virtual, global event focused on raising awareness and education around the threat of DDoS attacks. Hosted by Neustar with and exclusive media partner CSO, DDoS Awareness Day brings together top experts in global security to share their views, technical tips and from-the-trenches experience. Attendees will also be given access to a wealth of DDoS materials: white papers, surveys, presentations, best practices and more. more

Software-Defined Networking: What’s New, and What’s New for Tech Policy?

The Silicon Flatirons Conference on Regulating Computing and Code is taking place in Boulder. The annual conference addresses a range of issues at the intersection of technology and policy and provides an excellent look ahead to the tech policy issues on the horizon, particularly in telecommunications. I was looking forward to yesterday's panel on "The Triumph of Software and Software-Defined Networks", which had some good discussion on the ongoing problem surrounding security and privacy of the Internet of Things (IoT)... more

Ericsson Predicts 50 Billion Connections by 2020

At a recent shareholders' meeting in Stockholm, Ericsson's CEO has reaffirmed company's vision of having 50 billion internet-connected devices by 2020: "Today we already see laptops and advanced handsets connected, but in the future everything that will benefit from being connected will be connected." As an example of connected devices, a research engineer showed real life mobile health applications and how heart monitoring can be done remotely over mobile networks. more

Internet Service Quality Measured from Thousands of Locations

RIPE Atlas, the new active measurements network maintained by the RIPE NCC, gives you a way to easily measure the quality of your Internet services. RIPE Atlas is designed in such a way that it can collect data for analysis from a great number of locations on the Internet. The actual measurement devices, or "probes", are so small that they can be easily deployed in a home environment. more

Why R&E Networks Should Be Aware of the CDN Interconnect Initiative (CDNI)

At the recent IETF meeting there has been considerable discussion about interconnection of Content Delivery Networks. A lot of this is being driven unfortunately by the incumbent telco/cableco's who never understood CDN in the first place, and now want to assert control over this critical new Internet architecture, much in the same way that they want to take control over open WiFi hot spots as part of an integration strategy with their 3G/4G networks. more

What COVID-19 Means for Network Security

The COVID-19 Pandemic is causing huge social and financial shifts, but so far, its impact on network security has gone under-reported. Yet with thousands of companies worldwide requiring millions of employees to work remotely, network administrators are seeing unprecedented changes in the ways that clients are using their networks and new threats that seek to leverage the current crisis. more
