Secure InfluxDB 3 Enterprise at the authentication, authorization, and host
levels.

## Authentication

Verify the identity of clients and users that connect to InfluxDB 3 Enterprise.

* [Manage tokens](/influxdb3/enterprise/admin/tokens/): Authenticate API and CLI
  requests with `apiv3_` tokens.
* [Manage users and authentication](/influxdb3/enterprise/admin/security/manage-users/):
  Enable multi-user authentication so users log in with individual
  credentials.

## Authorization

Control what authenticated users and tokens can do.

* [Role-based access control (RBAC)](/influxdb3/enterprise/reference/internals/rbac/):
  Assign built-in roles to users and understand the permissions model.

## Host hardening

* [Harden the host and service](/influxdb3/enterprise/admin/security/harden-the-host/):
  Configure systemd sandboxing and host-level filesystem protections.
