How to Secure Kubernetes, the OS of the Cloud

As infrastructure becomes increasingly defined as code (IaC) and managed through Kubernetes, a paradigm shift is occurring that enhances developer responsibility and introduces new security challenges. This shift enables transformative concepts like immutability and allows developers to define infrastructure using tools like git, but it also broadens the attack surface due to potential vulnerabilities in the code. To address these challenges, a dual approach of "shift left" and "shift right" in security is recommended, where security measures are integrated early in the development process to catch vulnerabilities in infrastructure definitions and are also applied at runtime to manage the complexity and interdependence of microservices. By marrying IaC with runtime security, organizations can automate policy enforcement and reduce manual errors, ultimately creating a more secure environment from source through production.
