Why SASE Requires A New Way Of Thinking

The following post is sponsored by Palo Alto Networks. SASE, or Secure Access Service Edge, doesn’t require new skills for network engineers so much as a new mindset. You don’t learn a new routing protocol or encryption tunnel. You do need to embrace diverse connectivity options, hybrid work, and supporting applications that are on premises […]

Kubernetes Unpacked 006: The Impact Of Kubernetes On DevOps Teams

Kubernetes is hard. Regardless of what tech marketing says, DevOps teams are still trying to implement and figure out this whole Kubernetes thing. With multi-cloud, hybrid cloud, and on-prem Kubernetes implementations, how can teams start their journey and have an impact? Michael Levan catches up with Jeff Smith, Ops Director and author, to talk about his journey into Kubernetes for his team and what other teams should think about when implementing Kubernetes.

Cisco shakeup: Networking chief Todd Nightingale to helm Fastly

Cisco’s networking organization is getting a shake-up as its Enterprise Networking and Cloud business chief Todd Nightingale is leaving to become CEO of cloud content-delivery company Fastly.Nightingale has been with Cisco since 2012, coming over in the company’s acquisition of Meraki and has been a key driver to “Merakify” Cisco’s multi-billion dollar enterprise portfolios. That is to say Meraki’s technology has a reputation for being easy to use and manage and Cisco is now moving toward making that strategy a core part of its high-end enterprise hardware and software strategy.

Experiment with post-quantum cryptography today

Practically all data sent over the Internet today is at risk in the future if a sufficiently large and stable quantum computer is created. Anyone who captures data now could decrypt it.

Luckily, there is a solution: we can switch to so-called post-quantum (PQ) cryptography, which is designed to be secure against attacks of quantum computers. After a six-year worldwide selection process, in July 2022, NIST announced they will standardize Kyber, a post-quantum key agreement scheme. The standard will be ready in 2024, but we want to help drive the adoption of post-quantum cryptography.

Today we have added support for the X25519Kyber512Draft00 and X25519Kyber768Draft00 hybrid post-quantum key agreements to a number of test domains, including pq.cloudflareresearch.com.

Do you want to experiment with post-quantum on your test website for free? Mail [email protected] to enroll your test website, but read the fine-print below.

What does it mean to enable post-quantum on your website?

If you enroll your website to the post-quantum beta, we will add support for these two extra key agreements alongside the existing classical encryption schemes such as X25519. If your browser doesn’t support these post-quantum key agreements (and none at the time Continue reading

Are Cloud Outages the Result of Choosing Price Over Reliability?

Market pressures and risk tradeoffs made by cloud providers might be the key to understanding why outages happen and what lies ahead for resolving cloud outages that can bring down regional, if not national commerce.

Government-imposed internet shutdowns impacted 1.9 billion people in first half of 2022

Internet shutdowns by governments across the world impacted 1.89 billion citizens globally in the first half of 2022, a 22% increase when compared with the second half of 2021.A recent report compiled by VPN service provider Surfshark found there were 66 state-mandated internet blackouts imposed across six countries and territories during the period: Burkina Faso, India, Jammu and Kashmir, Kazakhstan, Pakistan, and Sudan. Local shutdowns were observed in India, Jammu and Kashmir region, and Pakistan, while Burkina Faso, Kazakhstan, and Sudan chose to cut down internet connections nationwide.While there was an overall decrease in the number of internet shutdowns during the period—72 cases in the first half of 2022 compared with 84 reported in the second half of 2021—the number of people impacted was much higher, as reliance on the internet has increased globally.To read this article in full, please click here

Using the yes command to automate responses

One of the more unusual Linux commands is named “yes”. It’s a very simple tool intended to help you avoid having to answer a lot of questions that might be asked when you run a script or a program that needs a series of responses to do its work.If you type “yes” by itself at the command prompt, your screen is going to start filling up with the just the letter “y” (one per line) until you hit control-C to stop it. It’s also incredibly fast. Unlike what you see displayed below, yes will likely spit out more than a million y’s in the time it likely takes you to reach down and press control-C. Fortunately, that’s not all that this command can do.To read this article in full, please click here

Bigger, Faster, Better (and Cheaper!)

There has been much speculation on the evolution of the Internet. Is our future somewhere out there in the blockchains? Is it all locked up in crypto? Or will it all shatter under the pressure of fragmentation? It seems to me that all this effort is being driven by a small number of imperatives: making it bigger, faster and better. Oh, and making it cheaper as well!

I, The Braggart – A Network Fable

My boss stepped into our shared cubicle space and rested his arm on top of the fabric wall. He peered down at me. “Hey.” He always started with a quiet “hey” when he was about to ask me to do something new. I glanced at my whiteboard filled with projects and statuses, and steeled myself for the fresh request.

“Hey. I just got out of a meeting with Lewis.” I groaned inwardly. Lewis was my boss’s boss, and while Lewis was a fantastic human being, meetings with him were usually in the context of projects. Big ones. I put on a fake smile to mask creeping despair. “Oh? How did that go?”

My boss ripped off the band-aid. “Lewis wants a monthly summary from everyone of what they’ve been doing. So, on the last Friday of the month, make sure you have all your project statuses updated, including key milestones. Your whiteboard is great for you and me since we share this space, but now you’re going to need to log your statuses into the project database.” He smirked. “Like a big boy.”

I died a little inside. One of the reasons I’d left consulting Continue reading

Hedge 141: Improving WAN Router Performance

Wide area networks in large-scale cores tend to be performance choke-points—partially because of differentials between the traffic they’re receiving from data center fabrics, campuses, and other sources, and the availability of outbound bandwidth, and partially because these routers tend to be a focal point for policy implementation. Rachee Singh joins Tom Ammon, Jeff Tantsura, and Russ White to discuss “Shoofly, a tool for provisioning wide-area backbones that bypasses routers by keeping traffic in the optical domain for as long as possible.”
