octarinesec/kube-scankube-scan: Octarine k8s cluster risk assessment tool
Try our free Kubernetes risk assessment tool today.
Run it on any cluster at any time. No data leaves your cluster. We do not collect any information.
For more information on Octarine see https://www.octarinesec.com.
Kube-Scan gives a risk score, from 0 (no risk) to 10 (high risk) for each workload. The risk is based on the runtime configuration of each workload (currently 20+ settings). The exact rules and scoring formula are part of the open-source framework KCCSS, the Kubernetes Common Configuration Scoring System.
KCCSS is similar to the Common Vulnerability Scoring System (CVSS), the industry-standard for rating vulnerabilities, but instead focuses on the configurations and security settings themselves. Vulnerabilities are always detrimental, but configuration settings can be insecure, neutral, or critical for protection or remediation. KCCSS scores both risks and remediations as separate rules, and allows users to calculate a risk for every runtime setting of a workload and then to calculate the total risk of the workload.
Please notice that kube-scan currently scans the cluster when starting and will re-scan it every 24 hours. Thus, if you want to get an up-to-date risk score (e.g. after installing a new app), you should restart the kube-scan pod.
kubectl apply -f https://raw.githubusercontent.com/octarinesec/kube-scan/master/kube-scan.yaml
kubectl port-forward --namespace kube-scan svc/kube-scan-ui 8080:80
Then set your browser to http://localhost:8080.
kubectl apply -f https://raw.githubusercontent.com/octarinesec/kube-scan/master/kube-scan-lb.yaml
Then get the load-balancer address by
kubectl -n kube-scan get service kube-scan-ui -o jsonpath={..ip}
or
kubectl -n kube-scan get service kube-scan-ui -o jsonpath={..hostname}
depending on the load-balancer type.
Then set your browser to that address.
If you applied kube-scan to your cluster with the load balancer service:
"HOST" refers to the external ip of the service.
If you used port-forward:
"HOST" refers to "localhost:8080"
Getting all of the risks in your cluster:
GET http://HOST/api/risks
Requesting the kube-scan service to calculate again the risks (in case a resource was changed):
POST http://HOST/api/refresh
This might be a long operation - depending on the cluster size, so you can pull the refresh operation status:
GET http://HOST/api/refreshing_status
Build the server image (from root folder)
cd server
docker build -t SERVER_TAG_NAME .
docker push SERVER_TAG_NAME
Build the client image (from root folder)
cd client
docker build -t CLIENT_TAG_NAME .
docker push CLIENT_TAG_NAME
Set kube-scan containers images on the desired yaml (from root folder) kube-scan container with SERVER_TAG_NAME kube-scan-ui container with CLIENT_TAG_NAME
Apply the desired yaml and use "quick start" or "using load-balancer" instructions
kubectl delete -f https://raw.githubusercontent.com/octarinesec/kube-scan/master/kube-scan.yaml
In case of using a load-balancer:
kubectl delete -f https://raw.githubusercontent.com/octarinesec/kube-scan/master/kube-scan-lb.yaml
