Related Features

Cerberus Security Suite

CrowdSec is Layer 1 of the Cerberus security suite:

• Layer 1: CrowdSec (IP reputation)
• Layer 2: WAF (Web Application Firewall)
• Layer 3: Rate Limiting
• Layer 4: ACL (Access Control Lists)

All layers are controlled via SecurityConfig and can be enabled/disabled independently.

---

Notes

1. Testing Priority:

   • Frontend preset API client needs tests
   • Console enrollment needs full test coverage
   • Export utilities need tests

2. Architecture:

   • CrowdSec runs as a separate process managed by Charon
   • Configuration stored in data/crowdsec/ directory
   • Process state reconciled on container restart
   • Caddy bouncer communicates with CrowdSec LAPI

3. Configuration Flow:

   • User changes mode in UI → SecurityConfig updated
   • security.crowdsec.enabled Setting can override mode
   • Caddy config regenerated with bouncer enabled/disabled
   • Startup reconciliation ensures process state matches config

4. Future Improvements:

   • Add webhook support for CrowdSec alerts
   • Implement preset validation before apply
   • Add telemetry for preset usage
   • Improve LAPI health monitoring

---

PHASE 2A: API Client Tests

1. /frontend/src/api/__tests__/presets.test.ts

Purpose: Test preset API client with focus on caching and error handling

Test Scenarios:

Basic Happy Path

describe('listCrowdsecPresets', () => {
  it('should fetch presets list with cached flags', async () => {
    // Mock: API returns presets with various cache states
    const mockPresets = [
      { slug: 'bot-mitigation', cached: true, cache_key: 'abc123' },
      { slug: 'honeypot', cached: false }
    ]
    // Assert: Proper GET call to /admin/crowdsec/presets
    // Assert: Returns data.presets array
  })
})

describe('pullCrowdsecPreset', () => {
  it('should pull preset and return preview with cache_key', async () => {
    // Mock: API returns preview content and cache metadata
    const mockResponse = {
      status: 'success',
      slug: 'bot-mitigation',
      preview: '# Config content...',
      cache_key: 'xyz789',
      etag: '"abc"',
      retrieved_at: '2025-12-15T10:00:00Z'
    }
    // Assert: POST to /admin/crowdsec/presets/pull with { slug }
  })
})

describe('applyCrowdsecPreset', () => {
  it('should apply preset with cache_key when available', async () => {
    // Mock: API returns success with backup path
    const payload = { slug: 'bot-mitigation', cache_key: 'xyz789' }
    const mockResponse = {
      status: 'success',
      backup: '/data/backups/preset-backup-123.tar.gz',
      reload_hint: true
    }
    // Assert: POST to /admin/crowdsec/presets/apply
  })

  it('should apply preset without cache_key (fallback mode)', async () => {
    // Test scenario: User applies preset without pulling first
    const payload = { slug: 'bot-mitigation' }
    // Assert: Backend should fetch from hub API directly
  })
})

describe('getCrowdsecPresetCache', () => {
  it('should fetch cached preset preview', async () => {
    // Mock: Returns previously cached preview
    const mockCache = {
      preview: '# Cached content...',
      cache_key: 'xyz789',
      etag: '"abc"'
    }
    // Assert: GET to /admin/crowdsec/presets/cache/:slug with URL encoding
  })
})

Edge Cases & Bug Exposure

🐛 BUG TARGET: Cache Key Mismatch

it('should handle stale cache_key gracefully', async () => {
  // Scenario: User pulls preset, backend updates cache, user applies with old key
  // Expected: Backend should detect mismatch and re-fetch or error clearly
  // Current Bug: May apply wrong version silently
  const stalePayload = { slug: 'bot-mitigation', cache_key: 'old_key_123' }
  // Assert: Should return error or warning about stale cache
})

🐛 BUG TARGET: Network Failures During Pull

it('should handle hub API timeout during pull', async () => {
  // Scenario: CrowdSec Hub API is slow or unreachable
  // Mock: API returns 504 Gateway Timeout
  // Assert: Client should throw descriptive error

BUG EXPOSURE STRATEGY

Based on Recent Hotfixes:

🐛 Focus Area 1: Toggle State Mismatch After Restart

Files to Test: useSecurityStatus, Security.tsx, preset application Test Strategy:

• Simulate container restart (clear React Query cache)
• Verify that CrowdSec toggle state matches backend SecurityConfig
• Test that LAPI availability doesn't cause UI state mismatch
• Check that preset application doesn't break toggle state

Specific Test:

it('should sync toggle state after simulated restart', async () => {
  // 1. Set CrowdSec to enabled
  queryClient.setQueryData(['security-status'], { crowdsec: { enabled: true } })

  // 2. Clear cache (simulate restart)
  queryClient.clear()

  // 3. Refetch status

})

🐛 Focus Area 2: LAPI Readiness/Availability Issues

Files to Test: api/crowdsec.ts, statusCrowdsec(), decision endpoints Test Strategy:

• Test scenarios where CrowdSec process is running but LAPI not ready
• Verify error handling when LAPI returns 503/504
• Test decision fetching when LAPI is unavailable
• Ensure UI doesn't show stale decision data

Specific Test:

it('should handle LAPI not ready when fetching decisions', async () => {
  // Mock: CrowdSec running but LAPI not ready
  vi.mocked(client.get).mockRejectedValueOnce({
    response: { status: 503, data: { error: 'LAPI not ready' } }
  })

  await expect(listCrowdsecDecisions()).rejects.toThrow()
  // UI should show loading state, not error
})

🐛 Focus Area 3: Preset Cache Invalidation

Files to Test: api/presets.ts, getCrowdsecPresetCache() Test Strategy:

• Test stale cache key scenarios
• Verify that applying preset invalidates cache properly
• Check that cache survives page refresh but not backend restart
• Test cache hit/miss logic

Specific Test:

it('should invalidate cache after preset application', async () => {
  // 1. Pull preset (populates cache)
  const pullResult = await pullCrowdsecPreset('bot-mitigation-essentials')
  const cacheKey1 = pullResult.cache_key

  // 2. Apply preset
  await applyCrowdsecPreset({ slug: 'bot-mitigation-essentials', cache_key: cacheKey1 })

  // 3. Pull again (should get fresh data, new cache key)
  const pullResult2 = await pullCrowdsecPreset('bot-mitigation-essentials')
  expect(pullResult2.cache_key).not.toBe(cacheKey1)
})

🐛 Focus Area 4: Console Enrollment Retry Logic

Files to Test: useConsoleEnrollment.ts, api/consoleEnrollment.ts Test Strategy:

• Test enrollment failure followed by retry
• Verify that transient errors don't mark enrollment as permanently failed
• Check that correlation_id is tracked for debugging
• Ensure enrollment key is never logged or exposed

Specific Test:

it('should allow retry after transient enrollment failure', async () => {
  const { result } = renderHook(() => useEnrollConsole(), { wrapper })

  // First attempt fails
  vi.mocked(consoleEnrollmentApi.enrollConsole).mockRejectedValueOnce(
    new Error('Network timeout')
  )
  result.current.mutate({ enrollment_key: 'key', agent_name: 'agent' })
  await waitFor(() => expect(result.current.isError).toBe(true))

  // Second attempt succeeds
  vi.mocked(consoleEnrollmentApi.enrollConsole).mockResolvedValueOnce({
    status: 'enrolled',
    key_present: true
  })
  result.current.mutate({ enrollment_key: 'key', agent_name: 'agent' })
  await waitFor(() => expect(result.current.isSuccess).toBe(true))
})
