Why the 1# Vulnerability for Cyber Attacks Will Be Apathy

Everyone has heard of the cyber security attacks on Target (2013), Home Depot (2014), Neiman Marcus (2014), Sony Pictures (2014), and the United States' second-largest health insurer, Anthem (reported February 2015), but have you heard of the security breaches for Aaron Brothers, Evernote (denial of service attack), P.F. Chang's China Bistro, Community Health Services, Goodwill Industries, SuperValu, Bartell Hotels, Dairy Queen, U.S. Transportation Command contractors, and more. more

AXIS - The Fulcrum of Africa’s Internet Success

The Internet Society (ISOC) has been working with the African Union (AU) to facilitate the African Internet Exchange System (AXIS). This AXIS project funded by the EU-Africa Infrastructure Trust Fund and the Government of Luxembourg will help keep Internet traffic in Africa internal to the continent and avoid expensive international transit costs and delay latency in routing Internet traffic through other continents. more

The Insecurity of Ambiguous Standards

Why are networks so insecure? One reason is we don't take network security seriously. We just don't think of the network as a serious target of attack. Or we think of security as a problem "over there," something that exists in the application realm, that needs to be solved by application developers. Or we think the consequences of a network security breach as "well, they can DDoS us, and then we can figure out how to move load around, so if we build with resilience (enough redundancy)... more

Group of Engineers Have Created a Way to Detect Dangerous Objects in Baggage Using Public Wifi

Report describes a technique with which public wifi can be used to identify in-baggage dangerous objects in public spaces that don't typically have affordable screening options. 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

Join the Quantum Internet Hackathon 2018

The eighth RIPE NCC hackathon takes on the Quantum Internet! The hackathon will be held during the weekend before RIPE 77 in Amsterdam, and is co-organised by QuTech and TU Delft, along with the RIPE NCC. We're bringing together network operators, quantum networking researchers, students, hackers, software developers and artists, to imagine and build the tools for the future Internet. more

EU’s Cyber Security Agency Identifying Five Areas as Critical IT Security

The EU's 'cyber security' Agency ENISA (The European Network and Information Security Agency) has launched a new report concluding that the EU should focus its future IT security research on five areas: cloud computing, real-time detection and diagnosis systems, future wireless networks, sensor networks, and supply chain integrity. more

Internet Infrastructure: Stability at the Core, Innovation at the Edge (Part 2 of 5)

For nearly all communications on today's Internet, domain names play a crucial role in providing stable navigation anchors for accessing information in a predictable and safe manner, irrespective of where you're located or the type of device or network connection you're using. Over the past 15 years hundreds of millions of domain names have been added to the Internet's Domain Name System (DNS), and well over two billion (that's Billion!) new users, some ~34 percent of the global population, have become connected. more

IPv6 and Airline Tickets… Tales of Two Transitions

The internet bus continues to accelerate straight into the IPv4 address depletion wall with spirited discussions continuing on how to divvy up the remnants of the address space. Obviously all five Regional Internet Registries (RIR's) want to make sure they get their fair share from IANA but what is a fair share remains the subject of interpretation. In the mean time, scenarios of a speculative land rush and auctions of ever smaller address blocks abound with unattractive consequences such as an explosion of the size of the routing table and a stunted growth of the global internet economy... In the meantime, the airline industry completed a rather significant migration of their own... more

Mitigating the Increasing Risks of an Insecure Internet of Things

The emergence and proliferation of Internet of Things (IoT) devices on industrial, enterprise, and home networks brings with it unprecedented risk. The potential magnitude of this risk was made concrete in October 2016, when insecure Internet-connected cameras launched a distributed denial of service (DDoS) attack on Dyn, a provider of DNS service for many large online service providers (e.g., Twitter, Reddit). Although this incident caused large-scale disruption, it is noteworthy that the attack involved only a few hundred thousand endpoints... more

TeleGeography’s Interactive Submarine Cable Map Is a Fun and Fascinating View Into Infrastructure

Ever want to know where all the submarine cables are that provide part of the physical infrastructure of the Internet? Or which cities in the world have the most connectivity via submarine cables? (or which regions might be single points of failure?) In doing some research I stumbled across this excellent site from the folks at TeleGeography... It is a very well done and captivating (to me, anyway) view into where all the current and planned submarine cables are located. more

Household Botnet Infections

Pinning down the number of infected computers is really, really hard. I'd go as far as saying it's practically impossible to calculate, let alone observe. Still, that's not going to stop people from attempting to guess or extrapolate from their own observations. Over the years I've heard "reliable" numbers ranging from 10% through to 60% -- and I don't trust any of them. There's a whole gaggle of reasons why the numbers being thrown out to the public are inaccurate and should ideally be interpreted with a lot of skepticism by any right-minded folks. 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

Guadeloupe Moves to Set Up Internet Exchange Point

Developments in the Caribbean digital space are fuelling initiatives to strengthen the Internet infrastructure in the region. In Guadeloupe, a recent agreement among three Internet service providers has cleared the way for the island to establish its first Internet exchange point. Commonly called an IX or an IXP, an Internet exchange point is a critical element of Internet infrastructure used to interconnect networks and deliver data traffic between them. more

IANA: The World Loses if the Technical Industry Checks Out

On Friday, 14 March 2014, the U.S. Department of Commerce National Telecommunications and Information Administration (NTIA) announced its intention to transition the IANA functions to the global multistakeholder community. As expected, the announcement has sent adrenaline coursing through the veins of Internet governance experts and government policy people the world over. I'd argue, however, that it is an important point for the Internet's technical experts to sit up and take notice, as well: the fact that you are probably saying "what problem does this solve?" is a testimony to how much works well today, and we want to make sure it continues to work well in any future arrangements. more
