DevOps’ish 198

Remember last week how I said things would be punchier? Well, I updated the DevOps’ish Solarwinds supply chain compromise Index. By the way, Microsoft says it was, “used by a different threat actor.”

I wrote the parts of the newsletter below, which are probably helpful. ¯\_(ツ)_/¯

The past few days have been incredibly challenging mentally and physically. I’m not sure if I would do it all the same way again. Sadly, I think I’m going to have to sideline myself a little more next year. The good news is, I get to try again next year. For that, I am truly thankful. The holidays, especially religious-based ones, are challenging for me. I have a challenging relationship with religion in general. That’s for a different blog though. For those celebrating holidays the past few weeks and the weeks ahead, I wish you all the best.

How Claude Shannon’s Information Theory Invented the Future
“The heart of his theory is a simple but very general model of communication: A transmitter encodes information into a signal, which is corrupted by noise and then decoded by the receiver. Despite its simplicity, Shannon’s model incorporates two key insights: isolating the information and noise sources from the communication system to be designed, and modeling both of these sources probabilistically.” I’ve touched this work with my own hands. Pushing signals to and fro, multiplexing them, sending them over the air only to be disassembled on the other side.

Analyzing Solorigate, the compromised DLL file that started a sophisticated cyberattack, and how Microsoft Defender helps protect customers
Take a deep dive into the DLL toppling security apparatus across the globe. Also, it was “used by a different threat actor.” Oh good… Multiple agencies knew about it and exploited it. Sit back and grab your popcorn and keep an eye on the index.

How GitOps Improves the Security of Your Development Pipelines
“GitOps is usually discussed in terms of boosting developer velocity. But another benefit – one that doesn’t always get as much attention – concerns its potential to improve security.” To go fast, you have to go safely and securely. Otherwise, you’re introducing risk. You’re human. Let a computer and the knowledge of as many viable sources as possible do the safety and security for you. But that in the GitOps toolchain and maybe, you won’t end up like Solarwinds (aka on the front page of news sources the world over).

Apple Setup Issues: Apple Watch Verification Failed, HomePod Stuck on Configuring
How’s that switch from Mesos to Kubernetes coming? Oh… Distributed systems are hard.

Executable PNGs
Imagine this concept with a tight bit of Go or Rust logic. Large PNGs would be odd but not easily detected as suspicious without some actual compute looking into it.

Linux Hardening Guide
I would have killed for this web site in the early 2000s. Many arguments and old ways could’ve been avoided.

Tools

Active-Active PostgreSQL Federation on Kubernetes
This is kinda a dream come true if you build this right (the article doesn’t mention the physics involved: latency, for example). But, it does cover HA in all locations with a single operator so that’s dope.
