Kubernetes

As I continue this series on CI/CD pipeline security, it is time to now work on securely building and deploying our application. This post picks up where my Build Secure Python Pipelines: Adding Tests and Hooks in Action post left off. In this post, we’ll continue our pipeline development by adding a container build and deployment to Kubernetes. In addition to this, we’ll add some security components to the build and deployment process....

After writing my From Scattered to Splunk: Bringing Order to Your Kubernetes Logs post, a buddy of mine Danny Ansell (oh by the way he does work for Cribl and used to work for Splunk) suggested that I could always import my logs into Cribl as well. I’m madly in love with Splunk and do so love one of their tag lines Splunk Rhymes with Drunk, but I’m always on the hunt for kicking the tires on new technology....

I also realized that I needed to get all of my Kubernetes into one place for a number of reasons. I’m most familiar with Splunk so it makes sense to centralize my Kubernetes logs with Splunk. In this post, I’m going to walk through configuring Splunk and Kubernetes so that all of my logs are in a central location....

In my previous From Reactive to Proactive: Transforming Security with Tetragon post, I got Tetragon installed and working. After doing some digging, I found that I was only generating events and logs for one of the k8 nodes in my cluster. This article focuses on how I noticed this and how to fix tetragon logging issues. Identifying That I Had a Logging Issue While poking around at the logs and events from Tetragon, I noticed that I wasn’t getting logs and events from all of my pods....

I previously blogged about Starboard and How to Install and Use Starboard to Protect Your Kubernetes Cluster. These articles were focused more on vulnerability and configuration management. Now, I wanted to focus my attention on runtime security observability using Tetragon. Getting Started With Tetragon The first step is to install it. The Tetragon website recommends using Helm 3 to deploy it so that’s what we’ll do. I’m deploying with just the default values for now...
