Figuring out how they work and how to securely configure them is entirely the operator’s responsibility.ĭeploying workloads securely: Whether you are using a Kubernetes distribution with pre-configured security controls or building a cluster and its security yourself, developers and application teams who may not be familiar with the ins and outs of Kubernetes may struggle to properly secure their workloads. While a number of Kubernetes security issues exist, the three most important to consider are:Ĭonfiguring Kubernetes security controls: When deploying Kubernetes yourself from open source, none of the security controls are configured out of the box. Kubernetes security in the SDLC Key Kubernetes security issues Deployment and cloud infrastructure security then monitor running applications and deliver insights back to developers, creating a positive feedback loop from code to cloud, and back to code Code is tested after the build stage to ensure that vulnerabilities do not make it to the live Kubernetes environment. In the below diagram, we see where Kubernetes security fits into the overall software development life cycle (SDLC). Where does Kubernetes fit within the overall development process? Without proper controls, a malicious actor who breaches an application could attempt to take control of the host or the entire cluster. Kubernetes security is important due to the variety of threats facing clusters and pods, including: This includes – but is not limited to – securing containers, configuring workloads correctly, Kubernetes network security, and securing your infrastructure. Kubernetes Security is defined as the actions, processes and principles that should be followed to ensure security in your Kubernetes deployments.
