Best practices for securing Kubernetes applications

The guide discusses the importance of securing Kubernetes applications and provides best practices for mitigating common security risks at each layer of the infrastructure. It highlights the need for a defense-in-depth strategy, which involves implementing security controls across multiple layers to protect against various types of threats. The guide covers application code and third-party dependencies, container images and workloads, Kubernetes clusters and pods, and cloud infrastructure hosting the application. It also explores how Datadog's Security Platform can help with end-to-end visibility into Kubernetes environments and provides tools for monitoring security risks, detecting attacks, and streamlining application security. The guide emphasizes the importance of regular audits, limiting access to sensitive resources, and using the principle of least privilege for cloud accounts. Additionally, it discusses securing Kubernetes infrastructure in the cloud by enabling audit logging, restricting access to provider metadata APIs, and implementing a multi-layered approach to security.
