SPONSORED: Ransomware may currently be the biggest bogeyman for cybersecurity pros, law enforcement, and governments, but it shouldn’t divert us from more traditional, but still very disruptive threats. …
DDoS DNS attacks are old-school, unsophisticated … and they’re back was written by Martin Courtney at The Next Platform.
An ipSpace.net subscriber sent me this question:
I am on job hunting. I have secured an interview and they will probably ask me about VxLAN BGP EVPN fabrics. If you have some time, it would be a great help for me if you could tell me 1 or 2 questions that you would ask in such interviews.
TL&DR: He got the job. Congratulations!

Disaggregation means a lot of things, but the one thing that it most certainly does not mean is that every little thing in a system necessarily has to be smashed apart and then put back together in a composable ways. …

On Tuesday, March 28, 2023, the US Government will launch the Summit for Democracy 2023, following up on the inaugural Summit for Democracy 2021. The Summit is co-hosted by the United States, Costa Rica, Zambia, the Netherlands, and South Korea. Cloudflare is proud to participate in and contribute commitments to the Summit because we believe that everyone should have access to an Internet that is faster, more reliable, more private, and more secure. We work to ensure that the responsibility to respect human rights is embedded throughout our business functions. Cloudflare’s mission — to help build a better Internet — reflects a long-standing belief that we can help make the Internet better for everyone.
Our mission and core values dovetail with the Summit’s goals of strengthening democratic governance, respect for human rights and human rights defenders, and working in partnership to strengthen respect for these values. As we have written about before, access to the Internet allows activists and human rights defenders to expose abuses across the globe, allows collective causes to grow into global movements, and provides the foundation for large-scale organizing for political and social change in ways that have never been possible before.

The last time I spent days poring over vendor datasheets collecting information for the overview part of Data Center Fabrics webinar a lot of 1RU data center leaf switches came in two form factors:
I expected the ratios to stay the same when the industry moved from 10/40 GE to 25/100 GE switches. I was wrong – most 1RU leaf data center switches based on recent Broadcom silicon (Trident-3 or Trident-4) have between eight and twelve uplinks.

Today on the Tech Bytes podcast, sponsored by Palo Alto Networks, we get into Secure Access Services Edge (SASE), which combines SD-WAN with cloud-delivered security services. You can integrate parts from different vendors, but Palo Alto Networks is here to make a case for why you might want to consider a single-vendor approach.

Similar to interior designers trying to fit the chairs, tables, and other furniture in rooms inside of a home, chip designers have to figure out where the various bits and pieces of a processor will lie on confined floor plans where latency between parts matters. …

During the last year we met with multiple edge customers, covering the automation needs for IT Linux infrastructure at scale across remote locations where there is often no IT staff on site. Think about retail stores, dark stores and warehouses where self-checkout, handhelds and POS devices hosting RHEL are distributed everywhere.
For industrial setups and manufacture, this could be the scenario for small factor servers and storage hosting logging monitoring to gather information about operational activities, which are located in secure facilities.
One of the recurrent needs for our customers with distributed devices is the ability to upgrade Linux devices faster, at scale, mostly due to regulations or security risks. Ideally, you should be able to patch at scale as soon as a vulnerability is identified.
The main challenge with the traditional RPM patching model is that it is incremental, and frequently some Linux devices might have slight differences. That is why there are new edge-focused capabilities and models that start with the premise that you could and should test a whole base image, and once it passes your validations, it should be deployed into all the target devices that Continue reading
This week's Network Break covers Arista's new WAN routers that get the company into the SD-WAN market, debates whether Aryaka targeting SMEs is a sign of problems or opportunity, and discusses an update on the size of the SASE market. We also look at an HPE acquisition, the use of exploding USBs to target journalists, space networking, and more.

Dropped packets have a profound impact on network performance and availability. Packet discards due to congestion can significantly impact application performance. Dropped packets due to black hole routes, expired TTLs, MTU mismatches, etc. can result in insidious connection failures that are time consuming and difficult to diagnose. Visibility into dropped packets offers significant benefits for network troubleshooting, providing real-time network-wide visibility into the specific packets that were dropped as well the reason the packet was dropped. This visibility instantly reveals the root cause of drops and the impacted connections.
