ChatGPT on BGP Routing Security

I wanted to include a few examples of BGP bugs causing widespread disruption in the Network Security Fallacies presentation. I tried to find what happened when someone announced beacon prefixes with unknown optional transitive attributes (which should have been passed without complaints but weren’t) without knowing when it happened or who did it.

Trying to find the answer on Google proved to be a Mission Impossible – regardless of how I structured my query, I got tons of results that seemed relevant to a subset of the search words but nowhere near what I was looking for. Maybe I would get luckier with a tool that’s supposed to have ingested all the world’s knowledge and seems to (according to overexcited claims) understand what it’s talking about.

Intel announces 144 core Xeon processor

Intel has announced a new processor with 144 cores designed for simple data-center tasks in a power-efficient manner.Called Sierra Forest, the Xeon processor is part of the Intel E-Core (Efficiency Core) lineup that that forgoes advanced features such as AVX-512 that require more powerful cores. AVX-512 is Intel Advanced Vector Extensions 512, “a set of new instructions that can accelerate performance for workloads and usages such as scientific simulations, financial analytics, artificial intelligence (AI)/deep learning, 3D modeling and analysis, image and audio/video processing, cryptography and data compression,” according to Intel.Sierra Forest signals a shift for Intel that splits its data-center product line into two branches, the E-Core and the P-Core (Performance Core), which is the traditional Xeon data-center design that uses high-performance cores.To read this article in full, please click here

Supermicro has a new liquid-cooled server for AI

With data center servers running hotter and hotter, the interest in liquid cooling is ramping up with vendors announcing servers that feature self-contained systems and businesses with expertise in related technologies jumping in.Liquid cooling is more efficient than traditional air cooling, and Supermicro is using it to cool the hottest processors in a new server designed as a platform to develop and run AI software.The SYS-751GE-TNRT-NV1 server runs hot. It features four NVIDIA A100 GPUs that draw 300W each and are liquid-cooled by a self-contained system.Some liquid cooling systems rely on water that is piped into the data center. The self-contained system doesn’t require that, so it makes the servers more widely deployable.The system is quiet, too; its running noise level is 30dB.To read this article in full, please click here

Hedge 172: Roundtable! SONiC, Open Source, and Complexity

It’s roundtable time at the Hedge! Eyvonne Sharp, Tom Ammon, and I start the conversation talking about the SONiC open source NOS, and then wander into using open source, build versus buy, and finally complexity in design and deployment.

Thanks for listening–if you have an idea for a Hedge episode, would like to be a guest, or know someone you think would be a good guest, let one us know!

Day Two Cloud 188: Out-Of-Band Management And Infrastructure Automation With ZPE Systems (Sponsored)

On today's Day Two Cloud podcast we talk through out-of-band management network design with sponsor ZPE Systems. If your idea of OOB management is a jump box and some terminal servers, there’s a lot more to the story when you bring automation tooling into the picture. We'll learn how ZPE gear works and talk with customer Vapor IO about using ZPE gear in its edge compute sites.

Killnet and AnonymousSudan DDoS attack Australian university websites, and threaten more attacks — here’s what to do about it

Over the past 24 hours, Cloudflare has observed HTTP DDoS attacks targeting university websites in Australia. Universities were the first of several groups publicly targeted by the pro-Russian hacker group Killnet and their affiliate AnonymousSudan, as revealed in a recent Telegram post. The threat actors called for additional attacks against 8 universities, 10 airports, and 8 hospital websites in Australia beginning on Tuesday, March 28.

Killnet is a loosely formed group of individuals who collaborate via Telegram. Their Telegram channels provide a space for pro-Russian sympathizers to volunteer their expertise by participating in cyberattacks against western interests.

This is not the first time Cloudflare has reported on Killnet activity. On February 2,  2023 we noted in a blog that a pro-Russian hacktivist group — claiming to be part of Killnet — was targeting multiple healthcare organizations in the US. In October 2022, Killnet called to attack US airport websites, and attacked the US Treasury the following month.

As seen with past attacks from this group, these most recent attacks do not seem to be originating from a single botnet, and the attack methods and sources seem to vary, suggesting Continue reading

Studying EVPN to Prepare for a Job Interview

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!

BrandPost: Speeding the Migration of IoT Workloads to the Cloud

By: Michael Tennefoss, VP of IoT and Strategic Partnerships, Aruba, a Hewlett Packard Enterprise company.Moving IoT workloads to the cloud, and securely exchanging data between cloud IoT services and both legacy and new IoT devices, can entail months of custom engineering. Most IoT vendors send sensor and actuator data in non-interoperable or proprietary formats that must be reformatted to make them usable by cloud applications. Additionally, legacy IoT devices lack modern cybersecurity mechanisms and cloud-compatible software stacks. Replacing legacy devices with new ones is cost prohibitive, while the engineering work to make IoT data payloads usable can be significant. And these expenses may be recurring, e.g., when new IoT devices from different vendors are added over time, post-acquisition of a new company, or following a site refresh.To read this article in full, please click here

Myth Busting: You Can’t Use Packet Monitoring for Enterprise Security

Security teams today realize the value of packet monitoring for cybersecurity. As they find more uses for packet monitoring, they shatter the myth that the latter is insufficient on its own.
