Managing SSH access at scale with HashiCorp Vault

HashiCorp Vault can serve as an SSH Certificate Authority to manage secure administrative access at scale using short-lived signed certificates instead of static SSH keys.

• •Vault's SSH secrets engine signs SSH public keys with time-limited validity and embeds access restrictions like port forwarding controls
• •Integration with HashiCorp Boundary enables just-in-time credential injection for seamless passwordless SSH authentication
• •Identity-based security model enforces user authentication before SSH access with RBAC policies controlling certificate signing permissions
• •SSH certificate approach eliminates risks of static key management including private key compromise, complex key rotation, and incomplete audit trails
