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.
