5G and 6G wireless technologies have security issues

Network security concerns remain an issue with the upcoming 5G and 6G wireless network standards.That's because security measures being aren't being adopted in new 5G standards, and there's a newly discovered potential for Man-in-the-Middle attacks in terahertz-based 6G networks, multiple research studies have discovered.One of those studies — a formal analysis of 5G authentication conducted by scientists from ETH Zurich, the University of Lorraine/INRIA, and the University of Dundee — found that criminals will be able intercept 5G communications and steal data because “critical security gaps are present,” the group says in their press release. That’s in part because “security goals are underspecified” and there’s a “lack of precision” in the 3GPP standards, they say.To read this article in full, please click here

United in Build. Come See Us at Mozfest and Start to Connect the World.

Builders, creators, inventors, and tinkerers – we can start to connect half the world. Meet us at Mozfest.

Around 3.5 billion people do not have Internet access, many of them living in remote locations. How can they share the benefits of this amazing resource?

Tackling the digital divide is not easy, but everyone can help. Community networks are a great way to get involved.

What Are Community Networks?

Community networks are a global movement. From Asia with the Wireless for Communities project to the Tusheti region of Georgia and Rhizomatica’s initiative in Oaxaca, Mexico, community networks are examples of how to build, empower, and sustain communities of people. By communities, for communities, with communities.

Sound awesome? Find us at Mozfest

If you love the Internet, you’ll love Mozfest.  This year you’ll be able to learn about community networks. First, visit us at the Science Fair. We’ll be featuring an interactive exhibit of photos and videos of community network projects from around the world.

From Zimbabwe to Georgia find out what it took to build each community network and why they are so unique.

There will also be a workshop where you can learn how to build your Continue reading

Introducing Spectrum with Load Balancing

Introducing Spectrum with Load Balancing
Introducing Spectrum with Load Balancing

We’re excited to announce the full integration of Cloudflare Spectrum with Load Balancing. Combining Spectrum with Load Balancing enables traffic management of TCP connections utilising the same battle tested Load Balancer our customers already use for billions of HTTP requests every day.

Customers can configure load balancers with TCP health checks, failover, and steering policies to dictate where traffic should flow. This is live in the Cloudflare dashboard and API — give it a shot!

TCP Health Checks

You can now configure Cloudflare’s Load Balancer health checks to probe any TCP port for an accepted connection. This is in addition to the existing HTTP and HTTPS options.

Health checks are an optional feature within Cloudflare’s Load Balancing product. Without health checks, the Cloudflare Load Balancer will distribute traffic to all origins in the first pool. While this is in itself useful, adding a health check to a Load Balancer provides additional functionality.

With a health check configured for a pool in a Load Balancer, Cloudflare will automatically distribute traffic within a pool to any origins that are marked up by the health check. Unhealthy origins will be dropped automatically. This allows for intelligent failover both within a pool and amongst Continue reading

Arista joins Juniper, Cisco in 400G Ethernet race

Arista joined the parade toward high-speed Ethernet with new switches capable of supporting 400G speeds and aimed at hyperscale cloud and data-center networks.The Arista 7060X4 Series platforms are based on the Broadcom 12.8Tbps Tomahawk 3 silicon and feature 32 400G ports. Each 400G port can be split into four 100G ports for a total of 128 100G ports in a 1U chassis. Arista also enhanced its EOS operating system to better support traffic management, load balancing, buffering and routing for the high-speed boxes.   [ Related: MPLS explained -- What you need to know about multi-protocol label switching Over time, Ethernet speed transitions have been the primary driver for improving both the throughput and price-performance of data-center networks. 400G Ethernet is the next major transition on this journey, Andreas Bechtolsheim, Arista’s chief development officer, wrote in a blog about the announcement.To read this article in full, please click here

Join Us: Immerse Yourself in Networking and Security at VMworld Europe

We are looking forward to a fantastic show at VMworld 2018 Europe. We have a ton of great content on networking and security to share with you including breakouts, labs, activities, and parties! You’ll have prime opportunities to learn about the Virtual Cloud Network, the latest on the NSX product portfolio, and network with your peers and VMware experts.

To get you started for a packed week of learning and fun, we highly recommend attending our two showcase keynotes:

First, at the NSX Keynote: Building the Network of the Future with the Virtual Cloud Network (Tuesday, 06 November, 14:00 – 15:00), you’ll hear Tom Gillis, the new GM of NSBU lead discussions on:

  • VMware’s vision for networking with the Virtual Cloud Network
  • The latest and greatest innovations across the NSX product portfolio
  • Joint solutions we are bringing to the cloud with IBM
  • A special conversation with key customers about how they are using NSX today
  • And, demonstrations showing the entire product portfolio in action including NSX Data Center, NSX Cloud, NSX SD-WAN by VeloCloud, and AppDefense

 

Next, at the Security Keynote: Transforming Security in a Cloud and Mobile World, (Wednesday, 07 November, 14:00 – 15:00), Tom Corn, Continue reading

What’s the Big Deal with Validation?

This blog post was initially sent to subscribers of my mailing list. Subscribe here.

In his Intent-Based Networking Taxonomy blog post Saša Ratković mentioned real-time change validation as one of the requirements for a true intent-based networking product.

Old-time networkers would instinctively say “sure, we need that” while most everyone else might be totally flabbergasted. After all, when you create a VM, the VM is there (or you’d get an error message), and when you write to a file and sync the file system the data is stored, right?

As is often the case, networking is different.

NSX at VMworld 2018 Europe – The Technical Session Guide

Hola! VMworld 2018 Europe is around the corner and we look forward to connecting with our VMware NSX community in Barcelona.  Before we go into session recommendations, let us give you a recap on what we have been up to since VMworld US.

Since VMworld US in August 2018, we have announced general availability for NSX-T Data Center 2.3. NSX-T Data Center 2.3 extends NSX platform support to Bare Metal servers, enhances multi-cloud control in AWS & Azure, advances security with N/S service insertion, and has many more enhancements.

Our friends from vSphere have also released vSphere 6.7 Update 1 which gives NSX-T N-VDS visualization in the vCenter now.

For automation fans, we have a Concourse CI pipeline which automates the NSX-T install. This pipeline can be used to stand up entire NSX-T environments on vSphere clusters by filing a simple parameter file.

NSX-T Concourse Pipeline information

Now, let’s talk about our VMworld Europe line-up. As usual, we have great technical deep-dives, deployment stories, and hands-on labs for you. For the technical enthusiasts who are interested in deep-dives and deployment strategies, here are a set of “geek” sessions to choose Continue reading
