More on Broadband Router Insecurity and Being Proactive

Fergie replied on NANOG to my recent post on the subject of broadband routers insecurity: "I'll even go a step further, and say that if ISPs keep punting on the whole botnet issue, and continue to think of themselves as 'common carriers' in some sense -- and continue to disengage on the issue -- then you may eventually forced to address those issues at some point in the not-so-distant future..." He is right, but I have a comment I felt it was important - to me - to make. Not just on this particular vulnerability, but on the "war"... more

Broadband Routers and Botnets: Being Proactive

In this post I'd like to discuss the threat widely circulated insecure broadband routers pose today. We have touched on it before. Today, yet another public report of a vulnerable DSL modem type was posted to bugtraq, this time about a potential WIRELESS flaw with broadband routers being insecure at Deutsche Telekom. I haven't verified this one myself but it refers to "Deutsche Telekom Speedport w700v broadband router"... more

Examining Two Well-Known Attacks on VoIP

VoIP is here to stay. In fact many incumbent telecommunication carriers have started offering VoIP service for sometime and several new VoIP service providers have emerged. Aside from issues such as quality of service, the aspect of security, or lack thereof, is misunderstood by some of the VoIP service providers. This purpose of this article is to discuss two of the most well known attacks that can be carried out in current VoIP deployments. more

ENUM: Mapping the E.164 Number Space into the DNS

Many communications networks are constructed for a single form of communication, and are ill suited to being used for any other form. Although the Internet is also a specialized network in terms of supporting digital communications, its relatively unique flexibility lies in its ability to digitally encode a very diverse set of communications formats, and then support their interaction over the Internet. In this way many communications networks can be mapped into an Internet application and in so doing become just another distributed application overlayed on the Internet. From this admittedly Internet-centric perspective, voice is just another Internet application. And for the growing population of Voice over IP (VoIP) users, this is indeed the case... more

What If They Simply Made Communications Technology Better?

Rob Hyndman has a pointer to Mark Cuban's latest: Think the Internet Will Replace TV? Think Again. Cuban's post can be summarized as: Today's broadband networks are too slow. The insatiable appetite for on-demand rich media content will soon overwhelm them. Telco's aren't putting in upgraded networks quickly enough to meet that demand. Cuban also provides some facts and figures to back up that claim. In the comments, readers have a number of viewpoints, including the view that Mark has ignored cable, and that cable can provide the required speeds and feeds... more

Today’s Carrier Networks as Trollways?

As I keep pointing out -- there is indeed a viable alternative of a real marketplace not a fake one. Today's system is a fake because it depends on capturing the value of the application - communications - in the transport and that is no longer possible because with the Internet the value is created OUTSIDE the network. One example of the collateral damage caused by today's approach is the utter lack of simple wireless connectivity. Another is that we have redundant capital intensive bit paths whose only purpose is to contain bits within billing paths. more

Examining the Reality of Convergence

If there is one word in the telecommunications that has suffered from over-abuse for many years now, it's convergence. The term has been liberally applied to each successive generation of communications technology for their supposed ability to solve a myriad of service delivery problems within a single unifying converged carriage and service delivery solution. Unfortunately, the underlying reality has always been markedly different from these wondrous promises, and we continue to see an industry that deploys a plethora of service delivery platforms and an equally diverse collection of associated switching and service delivery technologies. One can't help but wonder at the collective gullibility of an industry that continues to herald the convergent attributes of each new generation of communications technology, while at the same time being forced to admit that previous convergent promises have never been realized. more

The Effects of AI Expansion on Testing Models and Infrastructure

AI workloads are exposing the limits of traditional network planning and testing, pushing operators toward better traffic visibility, workload-aware policies and production-like testing before adding capacity to infrastructure they may not fully understand. more

NASA Awards Blue Origin Up to $700 Million for Mars Communications Network

NASA selected Blue Origin to build and operate a Mars communications network, extending commercial infrastructure into deep space with high-capacity relays and delay-tolerant networking designed for reliable, interoperable communications among future missions. more

The Missing Privacy Debate Around IPv6

IPv6 solves the Internet's address shortage and simplifies networking, but its technical elegance may carry a hidden cost: shifting privacy protections from architectural constraints toward policies controlled by Internet providers, corporations and governments. more

UK Warns of Rising Cyberattacks on Exposed Industrial Systems

Britain's cyber agency warns that attackers are increasingly targeting internet-exposed industrial systems, routers and other edge devices, with some intrusions causing real-world disruption and highlighting the growing risks of poorly secured operational technology worldwide. more

Starlink’s Unconventional Approach to Cellular

SpaceX is considering a terrestrial cellular network powered by Starlink satellite backhaul, but scarce spectrum, enormous capacity demands and entrenched rivals could make its boldest telecommunications gambit yet far harder to execute profitably at scale. more

Wi-Fi 7 Adoption Is Accelerating

Wi-Fi 7 is spreading rapidly across America, promising faster speeds, greater capacity and fewer connectivity headaches. With big internet providers driving adoption, the technology is reshaping home broadband even as Wi-Fi 8 approaches.

AI Duties Are Being Written but the Protocol Layer Is Missing

Recent AI containment failures expose a governance gap: harmful model behavior is often visible at the network boundary but poorly monitored. Adapting proven internet protocols could give governments and companies practical tools to enforce accountability. more

DNS Security Gets Fixed When Someone Notices - Not Before

A study of 309 universities, museums and sports brands finds DNS security follows visible threats rather than technical risk, leaving organisations well protected against familiar attacks while quieter weaknesses in critical infrastructure persist unnoticed. more
