»Control Groups

Vault Enterprise control groups enforce additional authorization factors before satisfying a client request. For example, when an authorized user requests to read EU customer data, at least two account manager approvals are required.

Control Groups in Vault Enterprise

Previously, control groups defined those conditions on the target path regardless of the request type. Vault 1.8 extended this feature so that you can narrow the scope of the control group to the capabilities level.

If you are new to control groups, read through the entire Control Groups tutorial. Otherwise, skip to the Define a Control Group for Operations section to learn about these new enhancements.

»Troubleshoot Irrevocable Leases

Vault 1.8 introduced enhanced expiration manager functionality to internally mark leases as irrevocable after 6 failed revoke attempts, and stops attempting to revoke them. This prevents Vault servers from trying to revoke all expired leases at once during startup.

The Troubleshoot Irrevocable Leases tutorial demonstrates these improvements.

»Diagnose Server Issues

When Vault server fails to start, the Vault operators have to troubleshoot the server configuration.

Vault diagnose workflow

To help the Vault operators, Vault 1.8 introduced the vault operator diagnose command.

»Inspect Data in BoltDB

When using Vault Integrated Storage as the storage backend, the cluster persists all encrypted data to a bbolt key/value store. The Inspecting Data in Integrated Storage tutorial walks through the Vault API to inspect data.

The Inspect Data in BoltDB tutorial demonstrates how to access low-level details from the database file when a Vault cluster is not operable.
