Configure HCP Vault Dedicated audit log streaming to Elasticsearch

Prerequisites

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

• A HCP account with Admin or Contributor role assigned in HCP

• A production grade HCP Vault Dedicated cluster

• An Elasticsearch cluster created in Elastic Cloud with permission to create a role, and a user.

  Note

  If you do not have a cluster running, refer to the Create a Vault Cluster on HCP or the Deploy HCP Vault Dedicated with Terraform tutorial to create an HCP Vault Dedicated cluster.

Configure Elastic Cloud

To configure HCP Vault Dedicated audit log streaming to Elasticsearch, you must provide a endpoint URL, username, and password for a user that has been assigned a role with adequate permission to the Elasticsearch cluster.

Create role

1. Log in to the Elastic Cloud console and navigate to the stack management security page.

   For example https://<your-elastic-cloud-url>:9243/app/management/security/

2. Click Roles, then click Create role.

3. Enter hcp-vault-log-streaming in the Role name textbox.

4. In the Cluster privileges pull down, select monitor.

5. Under Index privileges, enter * in the Indices pulldown menu.

6. Click the Privileges pulldown menu and select the following:

   • create
   • create_index
   • manage
   • manage_ilm
   • write

7. Click Create role.

Create user

1. From the stack management security page, click Users.

2. Click Create user.

3. Enter hcp-vault-log-streaming in the Username textbox.

4. Enter a secure password in the Password and Confirm password textbox. Make note of the username and password - you will need this to configure audit log streaming in the HCP Portal.

5. Click the Roles pulldown menu and select the hcp-vault-log-streaming role.

6. Click Create user.

Retrieve Elastic URL

1. Navigate to https://cloud.elastic.co/home.

2. Click Manage for the Elastic Cloud deployment you wish to send HCP Vault Dedicated audit logs to.

3. Under Applications click Copy endpoint for Elasticsearch. Make note of the endpoint URL - you will need this to configure audit log streaming in the HCP Portal.

   The URL will be in the format of https://123def789jkl.region.cloudprovider.es.io.

Enable audit logs streaming

1. Log in to the HCP Portal and navigate to the Vault clusters page.

2. Click the Vault cluster you wish to enable streaming for and click Audit Logs.

3. Click Enable log Streaming.

4. From the Enable audit logs streaming view, select Elastic as the provider and click Next.

5. Under Elastic configuration, enter the Endpoint URL, Elastic user, and Elastic password created in the Create user section.

6. Click Save.

   Note

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

Refer to the Elastic documentation for details on log exploration.

Example Terraform configuration (optional)

Refer to the Terraform Registry hcp_vault_cluster documentation for more information.

resource "hcp_vault_cluster" "example" {
  cluster_id = "vault-cluster"
  hvn_id     = hcp_hvn.example.hvn_id
  tier       = "standard_large"
  audit_log_config {
    elasticsearch_user = "actual-user"
    elasticsearch_password = "actual-password"
    elasticsearch_endpoint = "actual-url"
  }
}
