Introducing post-quantum Cloudflare Tunnel

Introducing post-quantum Cloudflare Tunnel

Undoubtedly, one of the big themes in IT for the next decade will be the migration to post-quantum cryptography. From tech giants to small businesses: we will all have to make sure our hardware and software is updated so that our data is protected against the arrival of quantum computers. It seems far away, but it’s not a problem for later: any encrypted data captured today (not protected by post-quantum cryptography) can be broken by a sufficiently powerful quantum computer in the future.

Luckily we’re almost there: after a tremendous worldwide effort by the cryptographic community, we know what will be the gold standard of post-quantum cryptography for the next decades. Release date: somewhere in 2024. Hopefully, for most, the transition will be a simple software update then, but it will not be that simple for everyone: not all software is maintained, and it could well be that hardware needs an upgrade as well. Taking a step back, many companies don’t even have a full list of all software running on their network.

For Cloudflare Tunnel customers, this migration will be much simpler: introducing Post-Quantum Cloudflare Tunnel. In this blog post, first we give an overview of how Cloudflare Tunnel Continue reading

SambaNova ships second-generation AI systems

SambaNova Systems is now shipping the second-generation of its DataScale systems specifically built for AI and machine learning.You may not have heard of SambaNova, a startup led by ex-Oracle/Sun hardware executives and Stanford professors, but its work is likely familiar. The Lawrence Livermore National Laboratory was an early adopter of DataScale and used the systems in its COVID-19 antiviral compound and therapeutic research in 2020.“Our systems were deployed in supercomputers at the Lawrence Livermore National Laboratory, which were then used by various parties for the research and development of COVID-19 antiviral compound and therapeutics,” said Marshall Choy, SambaNova’s senior vice president for products. “So, yes, they were a small part of that. As bad as the pandemic was, at least we got to do something good through it.”To read this article in full, please click here

Worth Reading: QUIC Is Not a TCP Replacement

Bruce Davie makes an excellent point in his QUIC Is Not a TCP Replacement article – QUIC not a next-generation TCP, it’s a reliable RPC transport protocol.

What Bruce forgot to mention is that we had a production-grade RPC transport protocol for years – SCTP (Stream Control Transmission Protocol) – but it had two shortcomings:

The state of 5G in South Asia 2022, country-by-country guide

The eight nations that constitute South Asia vary enormously in size and economic and technological power: from the tiny landlocked kingdom of Bhutan, population less than 1 million and a GDP of US$2.4 billion, to India with a population of 1.4 billion and a GPD of US$2.6 trillion.But their 5G progress does not match their size and economic power. The two smallest nations—Bhutan and Maldives—both have commercial 5G services. The two largest—India and Pakistan—have yet to get full commercial 5G services. In these and other countries the assignment and allocation to operators of spectrum for 5G are delaying service introduction.[ More from Network World: What is 5G? • When will 5G be available in India? ] 5G in Afghanistan Given the parlous state of the Afghani economy in the wake of the 2021 Taliban takeover and subsequent embargoes, it is hardly surprising that Afghanistan has no 5G services.To read this article in full, please click here

Worth Reading: EVPN/VXLAN with FRR on Linux Hosts

Jeroen Van Bemmel created another interesting netlab topology: EVPN/VXLAN between SR Linux fabric and FRR on Linux hosts based on his work implementing VRFs, VXLAN, and EVPN on FRR in netlab release 1.3.1.

Bonus point: he also described how to do multi-vendor interoperability testing with netlab.

If only he wouldn’t be publishing his articles on a platform that’s almost as user-data-craving as Google.

Decrypting TLS Traffic with PolarProxy on Client PC

The tutorial provides detailed steps for decrypting HTTPS traffic generated on a client computer with PolarProxy installed. Decrypted traffic is then processed by Wireshark running together with PolarProxy on the same PC. HTTPS is an implementation of TLS encryption on top of the HTTP protocol, which is used by all websites as well as some other web […]

Modular Network OS with Nokia SR Linux

I was lucky enough to have been invited to attend Network Field Day 29 this past September in San Jose, CA. This event brings independent thought leaders together with a number of IT product vendors to share information and opinions. We saw presentations from a pretty full range of vendors — from the chips to observability. It was a great event and worth a few hours to check out the videos. Thanks to Gestalt IT for getting me involved.

Nokia was among the list of high-end companies we saw. No, they don’t make phones any more (though they do market their name to products), but they are still in the full-power, throw-packets-as-fast-as-you-can markets for hyperscalers and such. If you’re old like I am, you might remember Nokia as the hardware that Checkpoint ran on for a while. My brain has done its best to filter memories of those devices, but, luckily, the Nokia team is doing some much better things these days.

SR Linux was one of the focuses and the big hitter for me. This is a modernization of the SR OS that was introduced 20 years or so ago, and gets us into a “world of streaming telemetry. Continue reading

Interacting with HashiCorp Vault using Python

Interacting with HashiCorp Vault using Python

In the realm of data security, HashiCorp Vault emerges as a formidable tool for safeguarding sensitive information. Its primary role? To serve as a secure and encrypted repository for your most prized secrets. Whether you choose to manage it independently through the open-source option or opt for the convenience of HashiCorp Cloud Platform's SaaS solution, Vault stands as a reliable guardian of your data, ensuring confidentiality and integrity are upheld with every interaction.

The Vault HTTP API serves as a versatile gateway, granting comprehensive control over Vault's functionalities through simple HTTP requests. Whether you're delving into secrets management or tackling encryption tasks, this API opens the door to Vault's full potential. And for Python enthusiasts like myself, there's an added layer of convenience: a meticulously crafted Python SDK, complete with thorough documentation, streamlining interactions with Vault.

In this blog post, we'll embark on a journey to set up a self-managed instance of Vault, exploring how to seamlessly integrate Python for streamlined interaction with the platform.

Installation

We'll kick start our Vault journey by spinning up an instance using Docker. To achieve this, we'll craft a docker-compose.yml file to orchestrate the process:

version: "3.9"
services:
  hashicorp-vault:
    build: .
    ports:
       Continue reading
