MKIT

MKIT is designed for identifying misconfigurations in managed Kubernetes clusters by leveraging open-source tools to validate various security-related configuration settings. The tool operates within a local Docker container, utilizing credentials to query cloud provider APIs (such as those for AKS, EKS, or GKE) and the Kubernetes API to inspect cluster configurations.

Technically, MKIT employs Chef Inspec-formatted profiles to check for misconfigurations, with specific profiles available for different cloud providers and standalone Kubernetes clusters. When executed, MKIT connects to the cloud provider's APIs and the Kubernetes API server to gather configuration data, which it then combines into a report viewable through a web UI hosted on http://localhost:8000.

Operationally, MKIT ensures that all results are stored locally within the Docker container and are not uploaded or shared, mitigating sensitive data exposure risks. However, this approach also means that results are transient and lost once the container is terminated. The tool's flexibility allows it to run against various Kubernetes environments, including standalone clusters, but this versatility comes with the need to manage different configuration files and credentials for each environment.

From a technical standpoint, MKIT's use of Docker containers and local web UIs simplifies deployment but may introduce limitations in terms of scalability and long-term result retention. The tool's reliance on Inspec profiles ensures a structured and repeatable audit process, but updates to these profiles are necessary to keep the tool effective against evolving security threats. Overall, MKIT provides a robust, localized solution for identifying and mitigating common Kubernetes security misconfigurations.
