# API Reference — Performing Kubernetes etcd Security Assessment
|
|
|
|
## Libraries Used
|
|
- **subprocess**: Execute kubectl, etcdctl commands
|
|
- **json**: Parse Kubernetes API resource output
|
|
- **re**: Extract etcd server URLs from API server arguments
|
|
|
|
## CLI Interface
|
|
```
|
|
python agent.py [--kubeconfig ~/.kube/config] encrypt
|
|
python agent.py access --endpoint https://127.0.0.1:2379 [--cert client.crt --key client.key --cacert ca.crt]
|
|
python agent.py secrets
|
|
python agent.py tls
|
|
python agent.py full [--endpoint https://127.0.0.1:2379]
|
|
```
|
|
|
|
## Core Functions
|
|
|
|
### `check_etcd_encryption(kubeconfig)` — Verify encryption at rest
|
|
Inspects kube-apiserver pod args for `--encryption-provider-config`, audit logging, TLS.
|
|
|
|
### `check_etcd_access(endpoint, cert, key, cacert)` — Test access controls
|
|
Uses etcdctl to check health and test for unauthenticated read access.
|
|
CRITICAL finding if data readable without credentials.
|
|
|
|
### `dump_secrets_check(kubeconfig)` — Audit stored secrets
|
|
Lists all cluster secrets, categorizes by type, identifies sensitive naming patterns.
|
|
|
|
### `check_etcd_tls_config()` — Verify TLS certificates
|
|
Checks etcd pod args for peer TLS, client TLS, and client certificate authentication.
|
|
|
|
### `full_assessment(kubeconfig, endpoint)` — Comprehensive security scan
|
|
Combines all checks into single report with risk level classification.
|
|
|
|
## Security Checks
|
|
| Check | Flag | Risk |
|
|
|-------|------|------|
|
|
| Encryption at rest | --encryption-provider-config | CRITICAL if missing |
|
|
| Client TLS | --cert-file / --key-file | HIGH if missing |
|
|
| Peer TLS | --peer-cert-file / --peer-key-file | HIGH if missing |
|
|
| Client cert auth | --client-cert-auth=true | MEDIUM if missing |
|
|
| Unauthenticated access | etcdctl get without certs | CRITICAL |
|
|
|
|
## Dependencies
|
|
System: kubectl, etcdctl (etcd client)
|
|
No Python packages required.
