The Christmas Goat and IPv6 (Year 11)

This is the fourth year now with almost no snow during the Christmas Goat event here in Sweden, and so once again, you get a photo without any snow. Because of Covid-19 and 99.99% people working for home, I have not even seen the Goat live this year... What a crazy year it has been! more

Unintended Consequences of Submarine Cable Deployment on Internet Routing

The network layer of the Internet routes packets regardless of the underlying communication media (Wifi, cellular telephony, satellites, or optical fiber). The underlying physical infrastructure of the Internet includes a mesh of submarine cables, generally shared by network operators who purchase capacity from the cable owners. As of late 2020, over 400 submarine cables interconnect continents worldwide and constitute the oceanic backbone of the Internet. more

DNS Oblivion

Technical development often comes in short, intense bursts, where a relatively stable technology becomes the subject of intense revision and evolution. The DNS is a classic example here. For many years this name resolution protocol just quietly toiled away. The protocol wasn't all that secure, and it wasn't totally reliable, but it worked well enough for the purposes we put it to. more

Protecting an Enterprise from Cyber Catastrophe

We are suffering an epidemic of cyberattacks while in a viral pandemic. This post is for those who have responsibility for assuring that the IT-based services offered by their enterprise can quickly recover in the case of successful cyber-attack or other disaster. University of Vermont Medical Center (UVMMC) is an excellent hospital. I owe my life to treatment there and am grateful for both the skill and the kindness of UVMMC staff. They have been devastated by a cyber-attack. more

An Innovative Framework That Will Help the IoT Industry Scale Into the Billions

The Internet of Things (IoT) is on an explosive growth trajectory. According to Transforma Insights, the number of IoT-connected devices is projected to increase to 24.1 billion worldwide by 2030. That's almost a three-fold increase from 2019. Much of this growth will be fueled by the coming 5G revolution, which will enable businesses and consumers to take advantage of a wide range of increasingly sophisticated connected devices. more

Cybersecurity Considerations in the Work-From-Home Era

Verisign is deeply committed to protecting our critical internet infrastructure from potential cybersecurity threats, and to keeping up to date on the changing cyber landscape. Over the years, cybercriminals have grown more sophisticated, adapting to changing business practices and diversifying their approaches in non-traditional ways. We have seen security threats continue to evolve in 2020, as many businesses have shifted to a work from home posture due to the COVID-19 pandemic. more

The End of Broadband Networks as We Know Them

A group of major telecommunications companies -- Vodafone, BT, Telefonica and Deutsche Telekom -- recently announced something a bit unexpected. In the Open BNG Operator Position Paper, they call for a fundamental, industry-wide change to the way broadband networks are built. Specifically, they advocate for collaboration throughout the telco world, with a convergence around open broadband network gateways (BNGs). more

Network Outages Go Global

On August 30, CenturyLink experienced a major network outage that lasted for over five hours and disrupted CenturyLink customers nationwide as well as many other networks. What was unique about the outage was the scope of the disruptions as the outage affected video streaming services, game platforms, and even webcasts of European soccer. more

A Brief Look at the Domain Attack Surface of Streaming Media Companies

The term "attack surface" is often heard in cybersecurity conversations. It refers to the sum of all possible attack vectors or the vulnerabilities that threat actors can exploit to penetrate a target network or damage an organization somehow. An unused and forgotten subdomain, for instance, can become an attack vector when taken over. Certain categories of companies have very large attack surfaces. Such is the case of streaming media businesses like Netflix and HBO Max. more

A Look at DNS Trends and What the Future May Hold

We used to think of computer networks as being constructed using two fundamental common infrastructure components: names and addresses. Every connected device had a stable protocol address to allow all other devices to initiate a communication transaction with this device by addressing a data packet to this protocol address. And every device was also associated with a name, allowing human users and human use applications to use a more convenient alias for these protocol addresses. 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

5G/F5G Cloud Announcements: NFV Game-Changing Confirmations

Over the past few days, Microsoft made two major announcements. One was a "playbook [for] providing a carrier-grade platform for edge and cloud computing to help network operators realize the full potential of 5G technology" using its it Azure cloud data centres. The second announcement was a new platform that enables satellite-based access to those same cloud data centres designated Azure Orbital. Coupled with these announcements was another one by Samsung... more

Your AI Strategy Canvas: Part 1

As the final project of my UC Berkeley School of Information course in Artificial Intelligence strategies, we had to submit an AI strategy canvas. Today, I will attempt to share important aspects of the canvas, so you and your team may have a template to work from and consider. Let's begin. We will look at both a strategy and operations perspective both internally and externally. Part one will include Internal and Operational Strategies, while Part II will examine external processes, threats, and procedures. more

Scaling the Root of the DNS

The DNS is a remarkably simple system. You send it queries, and you get back answers. Within the system, you see exactly the same simplicity: The DNS resolver that receives your query may not know the answer, so it, in turn, will send queries deeper into the system and collects the answers. The query and response process is the same, applied recursively. Simple. However, the DNS is simple in the same way that Chess or Go are simple... more

Beyond the Interweb

Today's Internet is a network of networks and seen through the lens of the web. We need to look beyond the engineering history to see the Internet in the context of the broader vision of JCR Licklider, an acoustic psychologist, and his vision of man/computer symbiosis... JCR Licklider would've been thrilled to see such a powerful man-machine symbiosis becoming so normal and having it work so well. Lick, as he was called, can be considered the grandfather of the Internet. more
