naisdevice is a mechanism enabling NAVs developers to connect to internal resources in a secure and friendly manner.
Each resource is protected by a gateway, and the developer is only granted access to the gateway if all of the following requirements are met:
- Has a valid account
- Has accepted naisdevice terms and conditions
- Device is healthy
- Is member of the AAD access group for the gateway (e.g. to connect to team A's DB (via gateway), you must be member of team A's AAD-group)
Executing make release-frontend is required for deploy of new naisdevice client to be released and made available for download/install/update.
- minimal attack surface
- instantly reacting to relevant security events
- improved auditlogs: who connected when and to what
- moving away from traditional device management enables building a strong security culture through educating our users on client security instead of automatically configuring their computers
The apiserver component serves as the gRPC API server, responsible for handling various configurations and managing communication with other agents. Its primary functionalities include:
- Serving the gRPC API.
- Distributing configurations to the following agents:
- Retrieving device health status from the
nais/kolide-event-handler.
# Create a sqlite database file with a mock device
go run ./hack/local-device.go
# Start apiserver
go run ./cmd/apiserver
## Run device agent with access to your local apiserver
go run ./cmd/naisdevice-agent --local-apiserverThe gateway-agent runs on virtual machines (VMs) and interacts with the apiserver to receive and apply configurations. Key features of the gateway-agent include:
- Streaming configurations from the
apiserver. - Dynamic setup of:
- WireGuard for communication from devices.
- iptables for forwarding traffic.
The auth-server operates in a cloud run environment and plays a crucial role in user authentication. Its functionalities include:
- Authenticating users.
- Issuing tokens to devices for secure communication.
The enroller is deployed on Cloud Run and is responsible for managing the enrollment process for both gateways and devices.
- Handling the enrollment of gateways and devices securely.
The device-helper serves as the gRPC API for the device-agent and performs essential setup tasks for devices. Key functionalities include:
- Providing a gRPC API for the
device-agent. - Reading device serial information.
- Configuring network interfaces, routes, and WireGuard for secure communication.
The device-agent is a crucial component responsible for managing device configurations and facilitating communication with the apiserver. Its main features include:
- Streaming configurations from the
apiserver. - Delegating configuration tasks to the
device-helpervia its gRPC API. - Serving status updates through its gRPC API to the CLI/systray.
- Executing the authentication flow to obtain user tokens.
The systray component acts as a graphical user interface (GUI) for the agent, utilizing its gRPC API. It provides a convenient way for users to interact with and monitor the agent's status.
The controlplane-cli serves as an administrative command-line interface (CLI) interacting with the apiserver through its gRPC API. This CLI is designed for administrative tasks and configurations.
The prometheus-agent component connects to all gateways over WireGuard and configures Prometheus (deployed on the same VM) to scrape relevant metrics.
- Establishing connections to gateways using WireGuard.
- Configuring Prometheus to scrape metrics from connected gateways.
