Kubernetes least privilege implementation using the Google Cloud as an example
Everyone knows it: granting privileges is always a balance between security, usability and maintenance effort. If permissions are granted very generously, the effort is very low and there are rarely any hurdles to use; however, security is compromised. If permissions are granted sparingly, security is higher, but there are costly processes and a lot of administrative overhead.

Coding Continuous Delivery: CIOps vs. GitOps with Jenkins
Continuous delivery (CD) is an agile software development approach that has proven to be a suitable way to reliably and repeatably produce high-quality software in short cycles. The use of containers and the cloud, e.g., on platforms such as Kubernetes (K8s), offers many opportunities to make CD processes more robust and simpler. One such option is GitOps. This article provides some concrete examples to illustrate the differences between classic CD pipelines (CIOps) and GitOps processes.

Kubernetes AppOps Security Part 6: Pod Security Policies (2/2) - Exceptions and Troubleshooting
Pod Security Policies (PSP) allow to use cluster wide settings that are used for all new containers. In comparison to the Security Context, the usage of PSPs not as easy, but especially for large organizations with large clusters it can be beneficial to use them, because they reduce the necessity for manual configuration.

Kubernetes AppOps Security Part 4: Security Context (2/2) – Background
A container is basically a normal Linux process that runs isolated from the rest of the system via certain kernel components. This makes containers lighter but more vulnerable than virtual machines (VMs). To reduce this vulnerability to attack, the container runtimes offer a variety of settings whose default values strike a compromise between usability and security.

Kubernetes AppOps Security Part 3: Security Context (1/2) – Good Practices
The virtual construct of a “container” is a normal Linux process at its core that largely runs in isolation from the rest of the system using certain kernel components. This makes containers lighter but more vulnerable than virtual machines (VMs). To reduce this vulnerability to attack, the container runtimes offer a variety of settings whose default values strike a compromise between usability and security.

Kubernetes AppOps Security Part 2: Using Network Policies (2/2) - Advanced Topics and Tricks
In a Kubernetes cluster, everything (nodes, pods, Kubelets, etc.) can communicate with each other by default. If an attacker succeeds in exploiting a security vulnerability in one of the applications, he can easily expand his attack to all underlying systems in the same cluster. You can restrict this vulnerability using the on-board network policy features found in Kubernetes.

Kubernetes AppOps Security Part 1: Using Network Policies (1/2) – Basics and Good Practices
If you deploy applications on a managed Kubernetes cluster, operations is responsible for security, right? Not really! Even though Kubernetes abstracts from hardware, its API offers many possibilities for developers to improve security for the applications that are operated on it, by not just using the default settings. This post explains for which attack vectors network policies can offer protection and it will also show pragmatic good practices based on practical examples.

Continuous Delivery with Sonatype Nexus, Jenkins and the Cloudogu EcoSystem
In order to meet the growing demand to release new features at an increasingly faster pace, these features must be implemented faster and faster. But that's just one side of the coin. After all, these features have to be put into production as well. Often, deployments are made manually and prone to errors. They tie up resources, and they may take a long time. The solution is complete automation, which is called Continuous Delivery.
