Set Up Vault
Secrets management.
Overview
Setting up Vault brings centralised secrets management online. Vault provides static and dynamic secrets, encryption-as-a-service, and audit logging; the install enables a security posture that ad-hoc secret storage cannot match.
- Secrets management. Static and dynamic secrets; produces centralised control over the secret surface.
- Auth methods. Token, AppRole, Kubernetes, AWS IAM, OIDC; matches caller identity to access.
- Path-based ACL. Fine-grained policies; produces real protection through least-privilege access.
- Audit logging plus auto-unseal. Every operation logged supports investigation; cloud KMS auto-unseal supports operations.
The approach
The practical approach: HA cluster from day one, auto-unseal with cloud KMS, dynamic secrets wherever possible, Kubernetes auth for pods, documented per-service integration. The team’s discipline produces predictable Vault that survives operator turnover.
- HA cluster. Three or five nodes with Raft storage; produces resilience without external storage dependency.
- Auto-unseal with KMS. Cloud KMS unseals automatically; supports operations through restarts and node replacements.
- Dynamic secrets where possible. Database, AWS, SSH credentials; the secret expires automatically, reducing exposure.
- K8s auth method plus documented integration. Pods authenticate via ServiceAccount; per-service auth and policy committed for investigation.
Why this compounds
Vault discipline compounds across services. Each integrated service centralises secrets; the team’s security posture grows; new services inherit the secrets pattern from day one.
- Reduced credential exposure. Dynamic secrets expire; the compromise window shrinks from years to hours.
- Better audit trail. Centralised logging supports investigation; "who accessed which secret when" is answerable.
- Better incident response. Centralised revocation supports response; compromised credentials get rotated quickly.
- Institutional knowledge. Each integration teaches secrets management; the team’s identity engineering muscle grows.
Setting up Vault is a security investment that pays off across years. Nova AI Ops integrates with secrets-management telemetry, surfaces patterns, and supports the team’s identity discipline.
