Securing the Routing System at NANOG 74

The level of interest in the general topic of routing security seems to come in waves in our community. At times it seems like the interest from network operators, researchers, security folk and vendors climbs to an intense level, while at other times the topic appears to be moribund. If the attention on this topic at NANOG 74 is anything to go by we seem to be experiencing a local peak. more

Google Signs Memoranda of Understanding With Four Cuban Organizations

Cuban President Miguel Díaz-Canel addressed the first annual meeting of Cuba's IT professional society, the Unión de Informáticos de Cuba. In his talk, Díaz-Canel announced that four Cuban organizations - the Havana City Historian's Office, the University of Computer Sciences (UCI), Infomed, Cuba's medical network, and the Ministry of Culture had signed memoranda of understanding (MOUs) with Google. more

IPv6 Security Considerations

When rolling out a new protocol such as IPv6, it is useful to consider the changes to security posture, particularly the network's attack surface. While protocol security discussions are widely available, there is often not "one place" where you can go to get information about potential attacks, references to research about those attacks, potential counters, and operational challenges. more

BGP Security: A Gentle Reminder that Networking is Business

At NANOG on the Road (NotR) in September of 2018, I participated in a panel on BGP security -- specifically the deployment of Route Origin Authentication (ROA), with some hints and overtones of path validation by carrying signatures in BGP updates (BGPsec). This is an area I have been working in for... 20 years? ... at this point, so I have seen the argument develop across these years many times, and in many ways. more

Getting on with Digital Transformation: Three Steps to Making Strategic Technology Choices

In a recently published Uptime Institute Survey, Uptime Institute found that organizations operating data centers are finding it increasingly difficult to recruit professionals skilled in security, networking, and hybrid technologies. This realization comes at an interesting time, as the monolithic business infrastructure built over the last two decades is now entering a period of transformation. 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

Nerd Knobs and Open Source in Network Software

Tech is commoditizing. I've talked about this before; I think networking is commoditizing at the device level, and the days of appliance-based networking are behind us. But are networks themselves a commodity? Not any more than any other system. We are running out of useful features, so vendors are losing feature differentiation. This one is going to take a little longer... more

DNSSEC and DNS over TLS

The APNIC Blog has recently published a very interesting article by Willem Toorop of NLnet Labs on the relationship between Security Extensions for the DNS (DNSSEC) and DNS over Transport Layer Security. Willem is probably being deliberately provocative in claiming that "DoT could realistically become a viable replacement for DNSSEC." If provoking a reaction was indeed Willem's intention, then he has succeeded for me, as it has prompted this reaction. more

Community Networks Could Help Strengthen the Caribbean Internet

By some estimates, only half of the world's population has internet access, leaving the other half at a sizeable competitive disadvantage. This profound connectivity gap is especially significant in the unserved and underserved areas of developing and least-developed countries. For people who live in these places, Internet connectivity is not just about the Internet. It is a lifeline that gives access to electronic commerce and telehealth services, distance learning, social and political engagement, government services... more

An Update on Securing BGP from IETF 102

One way or another we've been working on various aspects of securing the Internet's inter-domain routing system for many years. I recall presentations dating back to the late '90's that point vaguely to using some form of a digital signature on BGP updates that would allow a BGP speaker to assure themselves as to the veracity of a route advertisement. more

Will Cisco Make a Comeback in Cuba?

Is the recently announced Cisco Networking Academy at the Universidad de Ciencias Informáticas a belated drop in the bucket or the first step in a significant opening? Cisco dominated the infrastructure equipment market in Cuba and elsewhere during the early days of the Internet, but Huawei replaced them in Cuba... What does this mean? It might be a belated drop in the bucket. UCI has only 19 trained CNA instructors while the CNA curriculum is being taught by over 20,000 instructors at over 10,000 institutions. more

Internet Evolution: Another 10 Years Later

Ten years ago, I wrote an article that looked back on the developments within the Internet over the period from 1998 to 2008. Well, another ten years have gone by, and it's a good opportunity to take a little time once more to muse over what's new, what's old and what's been forgotten in another decade of the Internet's evolution... The evolutionary path of any technology can often take strange and unanticipated turns and twists. more

ARIN and Antigua & Barbuda Government to Hold Workshop on Internet Resilience

The American Registry for Internet Numbers (ARIN) is collaborating with the government of Antigua and Barbuda to strengthen the technical capacity of local network operators. ARIN is one of five registries responsible for coordinating Internet number resources worldwide. Its service area includes Canada, the United States, and several Caribbean countries. The collaboration with the Antigua and Barbuda government comes as part of a broader thrust by ARIN to support the development of the Internet across the region. more

Belize to Host Caribbean Peering and Interconnection Forum

Belize will host the fourth Caribbean Peering and Interconnection Forum, known as CarPIF, on June 13 and 14. Since its inception in 2015, CarPIF has brought together regional and international technology experts and telecommunications industry execs to discuss a range of topics related to Internet peering and interconnection trends, and their relevance to the Caribbean region. more

DNS Complexity Lessons

Recently, Bert Hubert wrote of a growing problem in the networking world: the complexity of DNS. We have two systems we all use in the Internet, DNS and BGP. Both of these systems appear to be able to handle anything we can throw at them and "keep on ticking." But how far can we drive the complexity of these systems before they ultimately fail? Bert posted a chart on the APNIC blog to illustrate the problem. more
