vlog. Episode 4. Discussion about RPKI OV (protecting routing in Internet)

Hello my friend,

In the era when Internet plays more and more crucial role in the global business, the security and the stability of Internet become to be an enormously important. So we need to protect it!

CY2019 Episode 4 // RPKI OV with Greg Hankins

In this episode, together with Greg Hankins from Nokia we discuss the protection of the BGP routing in Internet with the new framework called RPKI Origin Validation, which is one of the most tending topics these days.

The Week in Internet News: Balloon-based Internet Service Passes a Big Test

The sky’s the limit: An Internet connectivity balloon, operated by Google sister company Loon, has spent 223 days in the air and circled the globe in an effort to demonstrate the feasibility of balloon mesh networks, CNET reports. The P-496 spent 140 days testing flight algorithms off South America.

Bad for business: A recent law that forces Australian communications firms to give the government access to encrypted messages has hurt business there, the government says. The public perception about the downsides of the law has “had a material impact on the Australian market and the ability for Australian companies to compete globally,” Computerworld Australia reports.

Weak security: D-Link, a maker of routers, IP cameras and other Internet-connected devices, would be required to stand up a new comprehensive security program in a proposed cybersecurity settlement with the U.S. Federal Trade Commission, GovInfoSecurity says. In early 2017, the FTC alleged that D-Link “failed to take reasonable software testing and remediation measures to protect their routers and IP cameras against well-known and easily preventable software security flaws.” The company allegedly left default usernames and passwords on devices and stored login credentials insecurely, and it left a private code-signing key on a Continue reading

Myanmar’s March Towards a Digital Future

Earlier this month, in collaboration with the Asia-Pacific Telecommunity (APT) and the Government of the Republic of the Union of Myanmar, we delivered a training program on Internet Governance for 32 government officials in Myanmar’s capital city, Naypyidaw.

The program ran over three days covering various topics such as Internet policy principles and regulatory frameworks, Internet infrastructure and standards, Internet for development, and cybersecurity.

What impressed me was the participants’ interest in asking questions and their active participation in discussions – it was obvious they were all very eager to learn and explore ways they could apply the learnings in their roles in the various departments they were from. We also got to discuss and see what promise digital technology holds for the country.

I have had the opportunity to visit Myanmar several times, including well before the democratic reforms began. In the few years since those reforms brought Myanmar to the world stage, the country has gone through tremendous transformation. I distinctly remember the difficulties in getting access to the Internet and the lack of mobile phones during my earlier visits.

Today, it’s a very different story. There are multiple service providers, and multiple cable landing stations that provide Continue reading

What Happens When The Internet Breaks?

It’s a crazy idea to think that a network built to be completely decentralized and resilient can be so easily knocked offline in a matter of minutes. But that basically happened twice in the past couple of weeks. CloudFlare is a service provide that offers to sit in front of your website and provide all kinds of important services. They can prevent smaller sites from being knocked offline by an influx of traffic. They can provide security and DNS services for you. They’re quickly becoming an indispensable part of the way the Internet functions. And what happens when we all start to rely on one service too much?

Bad BGP Behavior

The first outage on June 24, 2019 wasn’t the fault of CloudFlare. A small service provider in Pennsylvania decided to use a BGP Optimizer from Noction to do some route optimization inside their autonomous system (AS). That in and of itself shouldn’t have caused a problem. At least, not until someone leaked those routes to the greater internet.

It was a comedy of errors. The provider in question announced their more specific routes to an upstream customer, who in turn announced them to Verizon. After that all bets are Continue reading

In Patagonia: A New Community Network in the Village of El Cuy

Patagonia, a region in Argentina made up of deserts, pampas, and grasslands, is known for its large areas of uninhabited territory. In the north sits the village of El Cuy, with just 400 residents. Far from the large urban centers, the people of El Cuy have adapted to the difficulties of accessing different services and technologies. The Internet is no exception, thanks to a new community network.

In several ways, the community network model represents the Internet model of networking come to life. Community networks are built and implemented by people, through collaboration – all stages of the process include the community working together. In the case of the El Cuy community network, support was also provided by the CABASE and the ENACOM.

For Christian O’Flaherty, the Internet Society’s senior development manager for Latin America and the Caribbean, Internet access has become a positive catalyst for community development. “The operation of this pilot program has motivated the residents to organize themselves into a cooperative. This step will allow inhabitants from El Cuy to have access to various fundings offered by actors such as ENACOM to increase the capacity of the Internet connection.”

Abel Martínez, a resident of El Cuy Continue reading

Becoming Broadband Ready Means Community Innovation and Collaboration

There are countless communities across North America that are hungry to see better broadband access for their residents. It’s clear to local leaders that high-quality Internet access is the bedrock of a healthy and successful community – providing job opportunities, bolstering education, transforming health care, and democratizing access to information. What isn’t always so clear is how to make it happen.

That’s why Next Century Cities teamed up with the Internet Society and Neighborly to create the Becoming Broadband Ready toolkit. This comprehensive toolkit provides local leaders with a roadmap to encourage broadband investment in their community.

While every community will choose to tackle connectivity a little differently – a small island community and a large urban center will likely have unique considerations and approaches – there are many common threads that run through successful broadband projects. Becoming Broadband Ready compiles these threads into an easy-to-use and impactful resource for any community, providing resources specific to:

  • Establish Leadership
  • Build a Community Movement
  • Identify Goals
  • Evaluate the Current Circumstance
  • Establish Policies and Procedures to Support Investment
  • Prioritize Digital Inclusion
  • Identify Legislative and Regulatory Barriers
  • Explore Connectivity Options
  • Explore Financing Options
  • Be a Clear Collaborator
  • Measure Success

Next Century Cities identified the Continue reading

Campus design feature set-up : Part 5

In this blog series, we’ve been on a journey of sorts. We’ve shown you all the different ways to set up the CL 3.7.5 campus feature: Multi-Domain Authentication in this 6-part series and guess what? We’re getting into the home stretch!

In blogs 1-4 we had guides for Wired 802.1x using Aruba ClearPass, Wired MAC Authentication using Aruba ClearPass, Multi-Domain Authentication using Aruba ClearPass and Wired 802.1x using Cisco ISE. After this blog, we’ll just have one more covering. Multi-Domain Authentication using Cisco ISE. But we’re not here to talk about those now.

In this fifth guide, I’ll be sharing how to enable Wired MAC Authentication in Cumulus Linux 3.7.5+ using Cisco ISE (Identity Services Engine) 2.4, Patch 8.

Keep in mind that this step-by-step guide assumes that you have already performed an initial setup of Cisco ISE .

Cisco ISE Configuration:

1. Add a Cumulus Switch group to Cisco ISE:

First, we are going to add a Network Device Group to Cisco ISE:

Administration > Network Resources > Network Device Groups. Click the “+Add” button

Make sure to set the “Parent Group” to “All Device Types.” The result will look Continue reading
