Process Targeting Cluster Kubernetes Docker Stats Endpoint

No violationsstackroxhighruntime

Detects misuse of the Kubernetes docker stats endpoint

Rationale: A pod communicating to a Kubernetes API from via command line is highly irregular
Remediation: Look for open ports that may allow remote execution. Remove network utilities like curl and wget that allow these connections. Consider a firewall deny ingress firewall rule to the node serving the API
