Configure HCP Vault audit logs streaming to Splunk

This tutorial covers configuration of HCP Vault audit logs streaming to your existing Splunk environment.

Prerequisites

To configure audit logs streaming to Splunk, you will need to have:

• Have access to a paid Splunk Cloud or Enterprise account.

  Note

  Splunk Cloud Trial account would not work with HCP Vault as its HEC (HTTP Event Collector ) listener is hosted using a self signed certificate that HCP won't trust.

• Your Splunk HEC and token.

  Note

  HEC endpoint should be created using events and not metrics index in Splunk.

• An account with Admin or Contributor role assigned in HCP

• A production grade HCP Vault cluster

  Note

  If you don't have a cluster running, refer to the Create a Vault Cluster on HCP tutorial to create an HCP Vault cluster through HCP Portal. Or, refer to the Deploy HCP Vault with Terraform tutorial to provision an HCP Vault cluster using Terraform.

Enable audit logs streaming

1. From the HCP Vault cluster Overview page, select the Audit Logs view.

2. Click Enable Streaming.

3. From the Enable audit logs streaming view, select Splunk as the provider and click Next.

4. Under Splunk configuration, enter your HTTP Event Collector (HEC) Endpoint URL and event collector Token.

5. Click Save.

   Note

   At this time HCP Vault only supports audit log streaming to one log endpoint at a time.

Refer to the Splunk documentation for instructions on log querying.
