Kubernetes security
From a single compromised container to full cluster control.
Kubernetes connects every service you run. A misconfigured permission or an over-privileged container can give an attacker access to every workload, every secret, and every connected system in the cluster. This assessment maps every path from a compromised container to full cluster control.
What I test
- →Permission misconfiguration: do service accounts and workloads have more access than they actually need?
- →Container escape: can a container break out of its isolation and access the underlying server?
- →Network isolation: can containers freely communicate with services they should never reach?
- →Secrets management: are passwords and API keys stored securely, or visible to anyone who can run basic commands?
- →Management interface exposure: is the Kubernetes control plane accessible without authentication?
- →Deployment safeguards: are there controls preventing deployment of insecure or over-privileged containers?
- →Persistent storage security: can data volumes be accessed by workloads that should not reach them?
- →Runtime configuration: do containers run with elevated privileges or unnecessary system capabilities?

Example findings
CRITICALContainer with host access granted. Escaped isolation and reached the underlying server.
CRITICALDefault container identity has full cluster administrator permissions.
HIGHCluster management interface accessible without any authentication.
HIGHDatabase passwords visible to any user who can inspect running containers.
