Tech Bytes: Using Opengear Every Day–For Disruptions And More (Sponsored)

Today on the Tech Bytes podcast we talk about how to use out-of-band management for daily networking tasks, not just when there’s a problem or crisis. Our sponsor is Opengear and we’re joined by Ramtin Rampour, Solutions Architect, to talk about use cases including zero touch provisioning, configuration, and more.

How chaos engineering can improve network resiliency

Conventional wisdom says, ‘If it ain’t broke, don’t fix it.’ Chaos engineering says, ‘Let’s try to break it anyway, just to see what happens.’The online group Chaos Community defines chaos engineering as “the discipline of experimenting on a system in order to build confidence in the system’s capability to withstand turbulent conditions in production.”Practitioners of chaos engineering essentially stress test the system and then compare what they think might happen with what actually does. The goal is to improve resiliency.For network practitioners who have spent their entire careers focused on keeping the network up and running, the idea of intentionally trying to bring it down might seem a little crazy.To read this article in full, please click here

And here’s another one: the Next.js Edge Runtime becomes the fourth full-stack framework supported by Cloudflare Pages

You can now deploy Next.js applications which opt in to the Edge Runtime on Cloudflare Pages. Next.js is the fourth full-stack web framework that the Pages platform officially supports, and it is one of the most popular in the 'Jamstack-y' space.

Cloudflare Pages started its journey as a platform for static websites, but with last year's addition of Pages Functions powered by Cloudflare Workers, the platform has progressed to support an even more diverse range of use cases. Pages Functions allows developers to sprinkle in small pieces of server-side code with its simple file-based routing, or, as we've seen with the adoption from other frameworks (namely SvelteKit, Remix and Qwik), Pages Functions can be used to power your entire full-stack app. The folks behind Remix previously talked about the advantages of adopting open standards, and we've seen this again with Next.js' Edge Runtime.

Next.js' Edge Runtime

Next.js' Edge Runtime is an experimental mode that developers can opt into which results in a different type of application being built. Previously, Next.js applications which relied on server-side rendering (SSR) functionality had to be deployed on a Node.js server. Running a Node.js Continue reading

Use VRFs for VXLAN-Enabled VLANs

I started one of my VXLAN tests with a simple setup – two switches connecting two hosts over a VXLAN-enabled (gray tunnel) red VLAN. The switches are connected with a single blue link.

I configured VLANs and VXLANs, and started OSPF on S1 and S2 to get connectivity between their loopback interfaces. Here’s the configuration of one of the Arista cEOS switches:

A Chinese law that went into effect six months ago required online service providers to file details of the algorithms they use with China’s centralized regulator, the Cyberspace Administration of China (CAC).

How is deep learning going to assist rather than replace the average creative worker? If replacement is the goal — valid, by the way, if a net positive for humanity — are we paying the people responsible for work the models have been trained on?

Since the WSJ and a viral TikTok video made quiet quitting a cultural phenomenon, it seems as though every news outlet, Fortune 500 CEO, lifestyle coach, or entry-level employee has something to say about quiet quitting.

After looking into the matter, I’m less confused but more distressed: Smart heating and cooling is even more knotted up than I thought. Ultimately, your smart thermostat isn’t made to help you. It’s there to help others—for reasons that might or might not benefit you directly, or ever.

This month, LinkedIn researchers revealed in Science that the company spent five years quietly researching more than 20 million users. By tweaking the professional networking platform’s algorithm, researchers were trying to determine through A/B testing whether users end up Continue reading

New research has disclosed what’s being called a security vulnerability in Microsoft 365 that could be exploited to infer message contents due to the use of a broken cryptographic algorithm.

Telcos deal with a considerable amount of multivendor devices. Although many hope/expect that these are equipped with state-of-the-art telemetry technologies, most of the time they’re not

Concerns over a critical authentication bypass vulnerability in certain Fortinet appliances heightened this week with the release of proof-of-concept (PoC) exploit code and a big uptick in vulnerability scans for the flaw.

Cracks and keygens have long been a problem for software vendors in that they allow users to install their products without needing to pay for a legitimate license. As the Internet and website development advanced and became more accessible, the number of sites offering software cracking tools grew.

The result is ChilliRack, a cooling system that Klein believes can address key challenges in the cost of cooling and the low utilization seen in many data centers.

With DevSecOps coming a long way as a discipline, there are now great frameworks and best practices for applying security gates in your CI, and later CD.

Heavy Networking 652: Why Networkers Should Want Routing Protocols Written In Rustlang

On today’s Heavy Networking episode, I talk with Nick Carter about Flock Networks, his routing protocol stack startup, as well as Nick’s love of the Rust programming language. As a network engineer, maybe you don’t think you care about Rust. Nick’s here to explain why the discerning network engineer might prefer their routing daemons to have been written in Rust. We also talk about the pleasures and travails of startup life.

Page Shield can now watch for malicious outbound connections made by third-party JavaScript code

Page Shield can now watch for malicious outbound connections made by third-party JavaScript code

Many websites use third party JavaScript libraries to cut development time by using pre-built features. Common examples include checkout services, analytics tools, or live chat integrations. Any one of these JavaScript libraries may be sending site visitors’ data to unknown locations.

If you manage a website, and you have ever wondered where end user data might be going and who has access to it, starting today, you can find out using Page Shield’s Connection Monitor.

Page Shield is our client side security solution that aims to detect malicious behavior and compromises that affect the browser environment directly, such as those that exploit vulnerabilities in third party JavaScript libraries.

Connection Monitor, available from today, is the latest addition to Page Shield and allows you to see outbound connections being made by your users’ browsers initiated by third party JavaScript added to your site. You can then review this information to ensure only appropriate third parties are receiving sensitive data.

Customers on our business and enterprise plans receive visibility in outbound connections provided by Connection Monitor. If you are using our Page Shield enterprise add-on, you also Continue reading

IoT security strategy from those who use connected devices

Freeman Health System has around 8,000 connected medical devices in its 30 facilities in Missouri, Oklahoma, and Kansas. Many of these devices have the potential to turn deadly at any moment. "That’s the doomsday scenario that everyone is afraid of," says Skip Rollins, the hospital chain's CIO and CISO.Rollins would love to be able to scan the devices for vulnerabilities and install security software on them to ensure that they aren't being hacked. But he can't."The vendors in this space are very uncooperative," he says. "They all have proprietary operating systems and proprietary tools. We can't scan these devices. We can't put security software on these devices. We can't see anything they're doing. And the vendors intentionally deliver them that way."To read this article in full, please click here

AMD promises faster and more efficient networking, eventually

This time last year, AMD had no networking products. Today, it has three, thanks to two separate acquisitions. It's a shift that's strengthening the company’s position against competitors like Intel and Nvidia by providing a full suite of silicon, including for the enterprise.To fill out its portfolio and stay competitive, AMD had to build up its offerings of workload accelerators and its networking technologies. It's a very active market, with Nvidia (BlueField), Intel (FPGA-based smartNICs), Marvell Technology (Octeon), and Broadcom (Stingray) all competing for the smartNIC market. AMD risked being left behind.To read this article in full, please click here
