Feature: CrowdSec Dashboard Integration with Observable Metrics

[Wikid82]

Summary

Adds a CrowdSec analytics dashboard to Charon's Security section, making security posture observable directly from the UI. Previously, viewing attack trends, scenario breakdowns, ban history, or top offenders required SSH access and running cscli commands. This feature closes that visibility gap.

Closes #26

What Changed

Backend: Aggregation API + Model Enrichment

• 6 new API endpoints under /api/v1/admin/crowdsec/ (admin auth required):
  • GET /dashboard/summary — aggregate counts (total decisions, active bans, unique IPs, top scenario, trend %)
  • GET /dashboard/timeline — time-bucketed decision counts with configurable intervals (5m/15m/1h/6h/1d)
  • GET /dashboard/top-ips — top attacking IPs ranked by decision count
  • GET /dashboard/scenarios — scenario breakdown with percentages
  • GET /alerts — paginated LAPI alerts with cscli fallback
  • GET /decisions/export — CSV/JSON export with CSV injection protection and 100k row limit
• SecurityDecision model enriched with Scenario, Country, ExpiresAt fields + 3 composite indexes for performant aggregation on large tables
• In-memory TTL cache (30s summary/alerts, 60s timeline/charts) with automatic invalidation on ban/unban operations
• Hybrid data sourcing: active decision counts from LAPI (authoritative), historical aggregations from SQLite, graceful fallback when LAPI is unreachable
• Race condition fixes: moved validateCrowdsecLAPIBaseURLFunc from package-level mutable to instance field on CrowdsecHandler; consolidated gin.SetMode into TestMain entrypoint

Frontend: Dashboard UI + Charts

• CrowdSec Dashboard page with Radix UI Tabs integration alongside existing Configuration tab
• 4 summary stat cards with trend indicators and aria-live="polite" for screen readers
• Ban timeline chart (Recharts AreaChart) showing ban/captcha events over time
• Top attacking IPs chart (Recharts horizontal BarChart) with top 10 offenders
• Scenario breakdown chart (Recharts PieChart) with percentage labels
• Active decisions table displaying IP, alerts count, last seen, country with full Go duration parsing
• Time range selector (1h/6h/24h/7d/30d) using role="radiogroup" with roving tabindex and arrow key navigation
• Alerts feed with pagination, page reset on range change, and guarded edge cases
• Export dropdown (CSV/JSON) with ARIA menu pattern, blob validation, and URL cleanup
• Code-split via React.lazy() + <Suspense> to avoid loading Recharts on the Configuration tab
• i18n across 5 locales (en, de, fr, es, zh)
• Recharts added as dependency (SVG-based, accessible, tree-shakeable)

Testing

• ~60 backend test functions covering all 6 endpoints, cache behavior, input validation, error paths, race conditions, and edge cases
• ~68 frontend unit tests (Vitest) across 8 test files for all dashboard components and hooks
• Playwright E2E tests for dashboard tab navigation, chart rendering, and export flows
• Backend coverage: 88.4% (threshold: 87%)
• Frontend coverage: 90%+ (threshold: 85%)
• Patch coverage: 98.1% (threshold: 90%)

Stability Fixes

• Eliminated data race on validateCrowdsecLAPIBaseURLFunc by moving to handler struct field
• Consolidated gin.SetMode(gin.TestMode) into single TestMain entrypoint across 80+ test functions
• Removed unsafe os.Setenv/os.Unsetenv calls from parallel cookie tests

New API Endpoints

Method	Path	Description
GET	/admin/crowdsec/dashboard/summary?range=24h	Aggregate stats with trend
GET	/admin/crowdsec/dashboard/timeline?range=24h&interval=1h	Time-bucketed ban counts
GET	/admin/crowdsec/dashboard/top-ips?range=24h&limit=10	Top attacking IPs
GET	/admin/crowdsec/dashboard/scenarios?range=24h	Scenario breakdown
GET	/admin/crowdsec/alerts?range=24h&limit=20&offset=0	Paginated LAPI alerts
GET	/admin/crowdsec/decisions/export?format=csv&range=24h	CSV/JSON export

All endpoints require admin authentication. Time ranges: 1h, 6h, 24h, 7d, 30d.

Accessibility

• All interactive elements keyboard navigable with visible focus indicators
• Time range selector uses role="radiogroup" / role="radio" with aria-checked, roving tabindex, Arrow/Home/End key support
• Summary cards use aria-live="polite" for dynamic updates
• Charts use role="img" with descriptive aria-label
• Export menu uses ARIA menu pattern with aria-controls
• WCAG 2.2 AA contrast verified for all chart colors
• Skip navigation and semantic landmarks maintained

---

Security

• No LAPI keys exposed in any API response
• SSRF-safe LAPI URL validation via existing validateCrowdsecLAPIBaseURL
• CSV export includes injection protection (cells starting with =, +, -, @ are escaped)
• Export capped at 100k rows to prevent resource exhaustion
• All endpoints behind admin authentication
• GORM scanner: 0 CRITICAL/HIGH findings
• Trivy filesystem scan: 0 HIGH/CRITICAL vulnerabilities
• Blob validation on frontend export responses

---

Performance

• Server-side caching: 30s TTL for summary/alerts, 60s for charts
• 3 composite database indexes for sub-200ms aggregation on 100k+ row tables
• Dashboard tab code-split via React.lazy (Recharts not loaded until tab visited)
• Recharts tree-shaken (only imported chart types bundled)
• Cache invalidated on ban/unban to prevent stale data

Screenshots

Dashboard screenshots pending — the feature is fully functional but screenshots require a running instance with CrowdSec decision data.

Out of Scope

• Real-time WebSocket streaming (polling with cache is adequate for v1)
• GeoIP map visualization (future enhancement)
• Dark mode chart theme (uses existing palette)
• i18n for chart data labels (scenario names come from CrowdSec in English)
• Custom scenario creation (managed via CrowdSec Hub/CLI)

Pull request overview

Adds a CrowdSec analytics dashboard to the Security section so administrators can observe attack/ban trends directly in the UI, backed by new backend aggregation/storage and updated CI/test protocols.

Changes:

• Add CrowdSec dashboard entry points in the frontend (tabbed UI + lazy-loaded dashboard hooks/components) and corresponding unit tests.
• Enrich backend decision storage for analytics and introduce a small in-memory dashboard cache; centralize gin.TestMode setup in handler tests.
• Update docs/changelog, bump container/dependency versions, and harden CI workflows (explicit permissions, action pin updates, added npm audit step).
