Individual skill
performing-kubernetes-etcd-security-assessment
Assesses the security posture of the etcd cluster backing Kubernetes: encryption at rest, TLS peer and client transport, access control, backup encryption, and network isolation. Use when auditing or hardening a control plane, reviewing whether Secrets are encrypted at rest, or protecting etcd backups, since etcd stores Secrets, RBAC policy, and ConfigMaps in plaintext by default. Keywords: etcd, EncryptionConfiguration, encryption at rest, peer TLS, snapshot, backup, control plane. Do not use for broad cluster-wide CIS checks - use performing-kubernetes-cis-benchmark-with-kube-bench.

# Performing Kubernetes etcd Security Assessment
## Overview
etcd is the distributed key-value store that serves as Kubernetes' backing store for all cluster data, including Secrets, RBAC policies, ConfigMaps, and workload configurations. Without proper hardening, etcd exposes all cluster secrets in plaintext, making it the highest-value target for attackers who gain control plane access. A comprehensive security assessment covers encryption at rest, TLS for transport, access control, backup security, and network isolation.
## When to Use
- When conducting security assessments that involve performing kubernetes etcd security assessment
- When following incident response procedures for related security events
- When performing scheduled security testing or auditing activities
- When validating security controls through hands-on testing
