Audience: Founders, platform engineers, and security engineers who need clear deployment choices and working appliance examplesTypical time: 10-20 minutes

Antes de comenzar

  • Create a scoped BlackShield API key for appliance ingestion and connector health reporting.
  • Choose one appliance for the first proof point. Do not deploy all six unless each one has a real traffic path to protect.
  • Confirm Docker can reach the BlackShield API over outbound HTTPS and that local metrics port 9090 is available.
  • Set the upstream target before putting perimeter or application appliances in a traffic path.

Placement overview

Place only the appliance that matches the boundary you actually control; each appliance polls BlackShield and reports findings independently.

The perimeter appliance is a TCP edge proxy, while the application appliance is the HTTP/WAF control.

Inline traffic-path examples

Use inline appliances where traffic already has a listener, proxy, or query path that can be routed through the container.

Endpoint runtime monitoring is host-local rather than an inline traffic proxy; run it only where host process visibility is allowed.

Configuration enables capabilities

The container starts with a common BlackShield connection, then specific env vars determine which enforcement behavior is active. UPSTREAM_ADDR enables TCP forwarding, UPSTREAM_URL enables WAF proxying, and METRICS_ADDR enables local Prometheus metrics.

Paso 1

Choose the appliance that matches the control gap

Start with the boundary where a missing active control would hurt first. The edge firewall protects TCP entry points; the WAF handles HTTP inspection.

  • Perimeter and edge security: Edge Firewall / TCP Reverse Proxy. Use when: Use it when the control gap is known bad source IPs reaching public TCP listeners before application code runs. Protects: Public TCP services and edge entry points from known hostile IPs and CIDRs. Placement: At the network edge as a TCP proxy. This is not a WAF; use the Application WAF for HTTP request inspection.
  • Network segmentation security: Microsegmentation Gateway. Use when: Use it when staging, production, admin, or tenant segments need an active policy check between them. Protects: Internal segment and trust-boundary crossings. Placement: At internal TCP routing or proxy boundaries where source and destination segment decisions can be enforced.
  • Endpoint detection and response: Host Runtime Protection. Use when: Use it when you need lightweight host runtime visibility and controlled active response before rolling out a full EDR program. Protects: Linux host process namespaces and critical file paths. Placement: On Linux hosts where process visibility is allowed. It runs in audit mode by default; enable enforcement deliberately.
  • Application security: Web Application Firewall (WAF). Use when: Use it when the control gap is web exploit traffic reaching APIs or web apps. Protects: HTTP applications and APIs from suspicious paths, query strings, headers, request bodies, oversized bodies, and HTTP rate-limit abuse. Placement: In front of a target HTTP service as the reverse proxy. This is the WAF appliance.
  • Data access security: SQL Firewall / Database Activity Proxy. Use when: Use it when customer data access needs query-level guardrails and evidence before a broader DLP rollout. Protects: SQL-like query paths and sensitive field access. Placement: In front of workloads that send SQL-like query strings for inspection before they reach a database-facing service.
  • Identity and administrative access security: Identity-Aware Proxy / Admin Access Gateway. Use when: Use it when high-risk admin paths need a lightweight identity enforcement point close to the service. Protects: Privileged sessions, revoked tokens, JWT validation boundaries, and MFA-sensitive paths. Placement: In front of administrative APIs or identity-sensitive service paths that need a session validation gate.

Cómo se ve el éxito

The customer knows which single appliance to try first and understands that perimeter is not the WAF.

Paso 2

Wire each appliance to BlackShield

All appliances use the same API origin and API key pattern, then sync threat intelligence or policy before reporting blocked activity as findings.

  • Edge Firewall / TCP Reverse Proxy: configure `BLACKSHIELD_API_URL`, `BLACKSHIELD_API_KEY`, `LISTEN_ADDR`, `UPSTREAM_ADDR`, `POLL_INTERVAL`, `METRICS_ADDR`, `FAIL_CLOSED`. Polls BlackShield IP threat-intel blocklists, rate-limits abusive sources, and reports dropped connections through findings ingestion.
  • Microsegmentation Gateway: configure `BLACKSHIELD_API_URL`, `BLACKSHIELD_API_KEY`, `LISTEN_ADDR`, `POLL_INTERVAL`, `METRICS_ADDR`. Syncs segmentation policy from BlackShield custom policies and reports denied segment-crossing packets.
  • Host Runtime Protection: configure `BLACKSHIELD_API_URL`, `BLACKSHIELD_API_KEY`, `POLL_INTERVAL`, `METRICS_ADDR`, `SCAN_INTERVAL`, `ENFORCEMENT_MODE`. Fetches file-hash and process indicators from BlackShield threat intelligence, audits matching processes, and can terminate them in enforce mode.
  • Web Application Firewall (WAF): configure `BLACKSHIELD_API_URL`, `BLACKSHIELD_API_KEY`, `LISTEN_ADDR`, `UPSTREAM_URL`, `POLL_INTERVAL`, `METRICS_ADDR`, `MAX_BODY_BYTES`, `FAIL_CLOSED`. Pulls BlackShield threat signatures and blocklisted indicators, inspects HTTP requests, and posts blocked web exploitation attempts as findings.
  • SQL Firewall / Database Activity Proxy: configure `BLACKSHIELD_API_URL`, `BLACKSHIELD_API_KEY`, `LISTEN_ADDR`, `POLL_INTERVAL`, `METRICS_ADDR`. Syncs BlackShield custom data-shielding policies and reports unauthorized sensitive-field access.
  • Identity-Aware Proxy / Admin Access Gateway: configure `BLACKSHIELD_API_URL`, `BLACKSHIELD_API_KEY`, `LISTEN_ADDR`, `POLL_INTERVAL`, `METRICS_ADDR`. Polls revoked-token indicators and identity policy signals from BlackShield, validates JWTs when configured, and reports blocked session attempts.

Paso 3

Validate signals and operating value

Treat the first deployment as a proof point: confirm the appliance starts, exposes metrics, syncs successfully, and creates useful BlackShield findings before widening the blast radius.

  • Edge Firewall / TCP Reverse Proxy: check 8081 proxy, 9090 metrics; expected telemetry includes Blocked source IP or CIDR, target listener, action, severity, rate-limit reason, and appliance heartbeat.
  • Microsegmentation Gateway: check 8082 proxy, 9090 metrics; expected telemetry includes Source segment, destination segment, payload preview, deny reason, and appliance sync health.
  • Host Runtime Protection: check 9090 metrics; expected telemetry includes Process name, PID, parent context, audit or kill action, file path events, and appliance metrics.
  • Web Application Firewall (WAF): check 8083 proxy, 9090 metrics; expected telemetry includes HTTP path, source address, matched path/query/header/body reason, blocked action, body-size limit, and application health.
  • SQL Firewall / Database Activity Proxy: check 8084 SQL proxy, 9090 metrics; expected telemetry includes Requester, query summary, restricted fields, masking or block action, and sync status.
  • Identity-Aware Proxy / Admin Access Gateway: check 8085 IAM gate, 9090 metrics; expected telemetry includes Role, resource, token fingerprint, revoked-token or JWT validation reason, MFA status, and appliance heartbeat.

Cómo se ve el éxito

Appliance events appear in BlackShield alongside scanner, network sensor, and security-agent evidence.
