# Kubernetes Security

* Kubernetes Architecture
* Kubernetes Attack Surface
  * Control Plane 
    * etcd
    * master nodes
* Kubernetes Secure Configurations
  * Public traffic to cluster is proxied through load balancer
  * Cluster RBAC
* Kubernetes Threat Model
* Tools 
  * Penetration Testing tool : <https://github.com/inguardians/peirates>&#x20;
  * Trivy Vulnerability scanner : <https://github.com/aquasecurity/trivy>
  * Deepce : Docker Enumeration <https://github.com/stealthcopter/deepce>
* Attack Paths
  * subdomain enumeration -> S3 bucket scan
  * Web application exploitation -> api call exploitation -> RCE ->SSRF -> access to pods
    * Ex: java struts running on internet facing pod (CVE-2017-5638)
  * Nuclei templates -> subdomains/api's&#x20;
