Visualise and Analyse Your Data Centre Fabric with HAWK

Hello my friend,

Some time ago in LinkedIn we announced that we are working on the tool, which will allows you to model and analyse your network. As one of our primary focuses is data centres, we started from there. Despite it is an early stages, but we are happy and proud to introduce you HAWK: Highly-efficient Automated Weapon Kit. For now, this is a collection of the tools for the network management and analysis, but probably later we will put it under a joint hoot of some front-end, who knows…

Where is the the border between network automation and software development?

In order to automate any network operation, you need to write a script, even if that is a simple one. On the other hand, any script is a program or software. This means that the creating of the scripts for the network automation is a form of the software development. And it is fun. Continue reading

Sarantaporo.gr Community Network: Connecting Communities Is a Marathon, Not a Race

Last week we shared the story of how the Sarantaporo.gr Community Network worked with the community of Sykea to help with a pressing problem. Like many other villages in the Thessaly region in central Greece, it lacked access to the Internet. When an alternative solution to Sykea’s connectivity challenges was found, an opportunity opened up […]

The Client to Cloud Enterprise

Every CIO needs to adopt a cloud strategy typically moving some e-commerce workloads to the public cloud. Yet, the migration path for the modern enterprise can be constrained by legacy barriers. With mission-critical applications that run in a diverse suite of legacy mainframe to helpdesk to IoT devices, how does one get started and what does this entail?

The reality for any enterprise whose core business is driven by a reliance on corporate-owned technology structure with strict ownership of critical assets is that it operates with many constraints. The cloudification and multi-cloud strategy requires a more pragmatic and systematic approach balancing workloads in the cloud and on-premise enterprise networks.

Reader Question: What Networking Blogs Would You Recommend?

A junior networking engineer asked me for a list of recommended entry-level networking blogs. I have no idea (I haven’t been in that position for ages); the best I can do is to share my list of networking-related RSS feeds and the process I’m using to collect interesting blogs:

Infrastructure

• RSS is your friend. Find a decent RSS reader. I’m using Feedly – natively in a web browser and with various front-ends on my tablet and phone (note to Google: we haven’t forgotten you killed Reader because you weren’t making enough money with it).
• If a blog doesn’t have an RSS feed I’m not interested.

Intel releases 3rd-gen Xeon Scalable processor

Intel today launched the third generation of its Xeon Scalable server-processor line with more than three dozen new chips built on its long-overdue 10-nanometer manufacturing process and featuring a host of specialized features for security and AI.The new chips were developed under the codename Ice Lake and were long in coming, due to the delays Intel had getting its manufacturing process down to 10nm. AMD, through its TSMC manufacturing partner, is at 7nm and its Epyc processors are slowly but increasingly taking market share from Intel.Now see "How to manage your power bill while adopting AI" Intel says the Ice Lake series has a 20% improvement in the number of instructions that can be carried out per clock cycle over the prior generation, thanks to the smaller process node letting them cram more transistors into the package.To read this article in full, please click here

How Calico Cloud’s runtime defense mitigates Kubernetes MITM vulnerability CVE-2020-8554

Since the release of CVE-2020-8554 on GitHub this past December, the vulnerability has received widespread attention from industry media and the cloud security community. This man-in-the-middle (MITM) vulnerability affects Kubernetes pods and underlying hosts, and all Kubernetes versions—including future releases—are vulnerable.

Despite this, there is currently no patch for the issue. While Kubernetes did suggest a fix, it only applies to external IPs using an admission webhook controller or an OPA gatekeeper integration, leaving the door open for attackers to exploit other attack vectors (e.g. internet, same VPC cluster, within the cluster). We previously outlined these in this post.

Suggested fixes currently on the market

Looking at the Kubernetes security market, there are currently a few security solutions that attempt to address CVE-2020-8554. Most of these solutions fall into one or two of three categories:

1. Detection (using Kubernetes audit logs)
2. Prevention (using admission webhook controller)
3. Runtime defense (inline defense)

A few of the solutions rely on preventing vulnerable deployments using an OPA gatekeeper integration; these solutions alert users when externalIP (possibly loadBalancerIP) is deployed in their cluster configurations. Most solutions, however, present a dual strategy with a focus on prevention and detection. They use an admission controller for Continue reading

History of Internet 2: Dale Finkelsen

The Internet was originally designed as a research network, but eventually morphed into a primarily commercial system. While “Internet 2” sounds like it might be a replacement for the Internet, it was really started as a way to interconnect high speed computing systems for researchers—a goal the Internet doesn’t really provide any longer. Dale Finkelsen joins Donald Sharp and Russ White for this episode of the History of Networking to discuss the origins of Internet 2.
