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

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

Amazon Targets Satellite-to-Phone Market With 5,105-Satellite Leo Expansion

Amazon has outlined plans for a 5,105-satellite constellation that will connect smartphones directly from space, expanding emergency and mobile services while intensifying competition in the fast-growing satellite-to-device communications market. more

Community Networks Offer a Durable Route Across the Digital Divide

An ITU report finds that community-owned networks, backed by reliable technology, flexible financing and supportive regulation, can bring affordable, meaningful internet access to remote populations that traditional providers have struggled to reach at lasting scale. more

FBI Warns of Russian Cyber Campaign Targeting Vulnerable Routers

The FBI and international partners warn that Russia's FSB Center 16 is exploiting vulnerable routers worldwide, highlighting persistent weaknesses in network security and urging organizations to adopt stronger protections to safeguard critical infrastructure against intrusion. more

Is AI Really Changing Internet Traffic Patterns?

Claims that AI is reshaping internet traffic are gaining attention, but evidence remains mixed as residential ISPs report little change while business networks see steadier demand and faster upstream growth today warrants closer industry scrutiny. more

UK Unveils AI Cyber Shield to Counter Machine-Speed Digital Threats

Britain is developing Cyber Shield, an AI-powered national cyber defense program designed to detect threats, automate responses and protect critical infrastructure as increasingly sophisticated attacks challenge conventional security and strain existing defensive capabilities. more

Network Challenges from AI Traffic

Cisco warns AI traffic will reshape internet infrastructure as inference workloads demand lower latency, stronger upstream capacity and new network architectures, with AI expected to generate one quarter of web traffic by 2035 worldwide eventually. more

IP Geolocation: The New Infrastructure for Internet Interoperability

IP geolocation has evolved from routing metadata into essential Internet infrastructure, enabling compliant content delivery, cybersecurity, and digital governance while raising urgent questions about transparency, interoperability, and fragmentation risks worldwide for policymakers and providers alike. more

June IPv4 Trends: The Quiet Return of the IPv4 Bull Market

New transfer data suggests IPv4's apparent decline has reversed as record trading, rising prices, infrastructure demand and tightening supply reveal a market driven by deployment rather than speculation once again despite accelerating IPv6 adoption globally. more

Vinton Cerf Retires After Two Decades at Google, Looks Ahead to AI Interoperability

Internet pioneer Vinton Cerf will retire from Google after more than two decades, leaving a legacy that shaped the modern internet while predicting standardized protocols will become essential for the next generation of autonomous AI agents. more
