開始前に

  • Use the managed Ubuntu/Debian bundle first when an existing Wazuh manager, OSSEC server, or OSSEC local install already writes JSON alerts.
  • For existing deployments, confirm a Wazuh manager, OSSEC server, or OSSEC local install is writing JSON alerts to `/var/ossec/logs/alerts/alerts.json`.
  • Set `BLACKSHIELD_OSSEC_MODE=managed-local` only after your organization approves the OSSEC GPLv2 local install path.
  • Do not point the local file collector at a Wazuh agent-only endpoint unless that endpoint is also where manager-side `alerts.json` is produced.
  • Use the advanced S3 or GCS path only when the alert-producing host cannot run the native managed service.
  • Create an ingestion API key in Settings -> API Keys with Ingestion scope before editing any generated env or secret values.
  • Rotate any `sp_...` key that was pasted into terminal transcripts, support tickets, or chat before retesting.

Understand and customize

Use the guided steps below when you want to tailor the rollout, validate ownership, or expand the deployment safely.

ステップ 1

Use the managed Linux path first

The managed installer makes VM scanner mean a working host scanner: it defaults to existing Wazuh or OSSEC alerts, while OSSEC local installation is an explicit customer-approved option.

  • Existing Wazuh manager, OSSEC server, or OSSEC local install: generate `deploy/vm-scanner/managed/`, set the ingestion key, and run the installer.
  • Fresh Ubuntu/Debian VM: set `BLACKSHIELD_OSSEC_MODE=managed-local` only after approving the OSSEC GPLv2 install path.
  • AWS CDK path: create a Python 3.11 venv, export BLACKSHIELD_API_URL and SCANNER_IMAGE_URI, then run `cdk bootstrap && cdk deploy`.
  • The existing-source path reuses `/var/ossec/logs/alerts/alerts.json` and makes sure JSON output is enabled.
  • Wazuh agent-only endpoints normally do not own the manager-side `alerts.json`; install BlackShield on the manager/server/local host, or use the S3/GCS sync path.
  • Fleet-noisy package and update activity is grouped with host/IP evidence; intrusion-like alerts stay per-host with actor and provenance fields.
  • Rotate any `sp_...` key pasted into terminals, tickets, or chat before retesting.

What success looks like

Rotate any `sp_...` key pasted into terminals, tickets, or chat before retesting.

ステップ 2

Generate the managed bundle

Download the recommended managed bundle first. It installs `/usr/local/bin/blackshield-vms-scanner-run`, the native package under `/opt/blackshield/vm-scanner/venv`, and a restartable systemd unit.

  • Managed Linux: generate `deploy/vm-scanner/managed/` for the default Ubuntu/Debian native service.
  • The generated env defaults to `BLACKSHIELD_OSSEC_MODE=existing`; compatibility `auto` and explicit `managed-local` remain supported.
  • `managed-local` downloads and installs OSSEC GPLv2 local mode, so use it only after customer approval.
  • Scanner state persists in `/var/lib/blackshield/vm-scanner/ossec-state.json` so restarts do not duplicate ingestion.
  • Advanced existing-source modes remain available below for Docker Compose, Docker-backed systemd, cron, AWS Fargate, and GCP Cloud Run.

What success looks like

Advanced existing-source modes remain available below for Docker Compose, Docker-backed systemd, cron, AWS Fargate, and GCP Cloud Run.

ステップ 3

Set the ingestion key and alert source

Create a dedicated ingestion key, then update the generated env file before running the installer.

  • Create an Ingestion API key in Settings -> API Keys and paste the raw `sp_...` value into `deploy/vm-scanner/managed/.env.vm-scanner`.
  • If an ingestion key was pasted into terminal output, tickets, or chat, revoke it and create a new key before retesting.
  • Leave `BLACKSHIELD_OSSEC_MODE=existing` for existing Wazuh/OSSEC alert sources.
  • Set `BLACKSHIELD_OSSEC_MODE=managed-local` only for customer-approved OSSEC local installation.
  • Leave `VMS_COLLECTOR_MODE=file` and `OSSEC_ALERTS_FILE=/var/ossec/logs/alerts/alerts.json` for the managed Linux path.
  • Only override `BLACKSHIELD_VMS_NATIVE_PACKAGE_URL` when you also provide the matching `BLACKSHIELD_VMS_NATIVE_PACKAGE_SHA256`.

What success looks like

Only override `BLACKSHIELD_VMS_NATIVE_PACKAGE_URL` when you also provide the matching `BLACKSHIELD_VMS_NATIVE_PACKAGE_SHA256`.

ステップ 4

Install and verify ingestion

Run the generated installer with sudo, then confirm OSSEC/Wazuh alerts are readable and the native BlackShield service is healthy.

  • Run `sudo ./install-managed-vm-scanner.sh` from `deploy/vm-scanner/managed/`.
  • Check `sudo systemctl status blackshield-vms-scanner --no-pager` and `curl http://localhost:8080/health`; healthy responses report `status: ok` and `total_findings_ingested`.
  • Check `curl http://localhost:8080/metrics` when you want the raw counters without the health wrapper.
  • For failures, run `sudo journalctl -u blackshield-vms-scanner -n 100 --no-pager`, `sudo -u blackshield-vms-scanner test -r /etc/blackshield/vm-scanner.env`, `sudo -u blackshield-vms-scanner test -r /var/ossec/logs/alerts/alerts.json`, and confirm OSSEC/Wazuh service status.
  • Trigger a test OSSEC or Wazuh alert and confirm a new finding appears in the platform Findings view within the next scan interval.
  • Open the finding detail and confirm Host Identity, Network / Actor, Detection Provenance, and Raw Evidence are populated from the alert where available.

What success looks like

Open the finding detail and confirm Host Identity, Network / Actor, Detection Provenance, and Raw Evidence are populated from the alert where available.

ステップ 5

Use advanced existing-source bundles when needed

Keep the original sidecar and cloud patterns for environments where OSSEC/Wazuh is already managed elsewhere or alerts are synced through object storage.

  • Docker Compose: generate `deploy/vm-scanner/` for an existing local alert file with a containerized scanner.
  • Docker-backed systemd: generate `deploy/vm-scanner/systemd/` when Docker is already your host runtime standard.
  • cron / one-shot: generate `deploy/vm-scanner/cron/` for periodic forwarding without a continuously running scanner.
  • AWS and GCP: generate the S3/GCS bundles when the manager/server host syncs `alerts.json` into object storage.

What success looks like

Existing OSSEC/Wazuh deployments can still use Docker, cron, and object-storage collectors without changing the managed Linux default.

Open source bundles

What success looks like

  • Local runtime health checks return `status: ok` and managed runtimes log successful scans without read failures.
  • `total_findings_ingested` increases after OSSEC or Wazuh generates a new alert.
  • Findings appear in the platform Findings view with host/IP/provenance context and scanner=vms.
