A friend of mine pointed me to a twitter thread on how to explain Kubernetes to a five year old. Since I have a two year old, this immediately popped into my head. I’ve seen the Lonely Goatherd scene from The Sound of Music many a time – my daughter absolutely loves it. And itContinue reading “Explaining Kubernetes to a Five Year Old”
Fun at the command line plotting JSON values at the terminal with jc, jq, and jp.
In this post we’ll configure a Security Sidecar Pattern which will provide application level protection and micro-segmentation within the Kubernetes cluster.
As we begin a new decade I thought it would be cool to see how the tools of the trade for pre-sales Systems Engineers in the network security field have changed and which tools the SE’s SE will need to be proficient with in 2020.
In this post we will take an insecure deployment and implement a Security Service Layer Pattern to block application layer attacks and enforce strict segmentation between services.
Try the jc web demo! I’m happy to announce that jc version 1.6.1 has been released and is available on github and pypi. To upgrade, run: New Parsers jc now includes 32 parsers! New parsers (tested on linux and OSX) include: Updated Parsers ifconfig parser now outputs rx_bytes and tx_bytes as integers. More OSX SupportContinue reading “JC Version 1.6.1 Released”
In this post we will set the groundwork to deep dive into the Security Service Layer Pattern with a live insecure deployment on Google Kubernetes Engine (GKE). By the end of this post you will be able to bring up an insecure deployment and demonstrate layer 7 attacks and unrestricted access between internal services.
In this multi-part blog series, I will describe some microservice security design patterns to implement micro-segmentation and deep inspection in the interior of your Kubernetes cluster to further secure your microservice applications, not just the cluster. I will also demonstrate the design patterns with working Proof of Concept deployments that you can use as a starting point.
Do one thing well. For command-line utilities to do their one thing “well” they must include standardized machine-readable output. Linux and all of its supporting GNU and non-GNU utilities should offer JSON output options.
I’m Kelly Brazil and I’ve been in the cybersecurity industry for a couple decades now. I taught myself how to program when I was in third grade and I love to dabble in lots of techie topics including network security, cloud computing, automation, microservice architectures and security, software defined networking and SD-WAN, linux, APIs, guitar,Continue reading “Hi, fellow cybersecurity and computing nerds!”
