- **Live Decisions:** See exactly who is being blocked and why in real-time.
### Rate Limiting
**What it does:** Limits how many requests any single IP can make in a given time window.
**Why you care:** Stops aggressive bots or abusive users from overwhelming your server.
**Where to find it:** Cerberus → Dashboard → Rate Limiting card, or click "Configure"
for full settings.
**Dashboard features:**
- **Status Badge:** The Rate Limiting card shows a clear "Active" or "Disabled" badge
so you know at a glance if protection is enabled.
- **Quick View:** See the current configuration directly on the Security dashboard.
**Configuration page features:**
- **Active Summary Card:** When rate limiting is enabled, a green summary card at the
top shows your current settings (requests/sec, burst limit, time window).
- **Real-time Updates:** Changes take effect immediately without server restart.
**Settings:**
- **Requests per Second:** Maximum sustained request rate (e.g., 10/sec)
- **Burst Limit:** Allow short bursts above the limit (e.g., 20 requests)
- **Time Window:** How long to track requests (e.g., 60 seconds)

# Implementation Plan: Rename WAF Card to Coraza on Cerberus Dashboard
# Plan Complete: Rate Limiting Bug Fix
## Overview
**Status:** ✅ Completed
**Completed:** December 2024
Modify the WAF card on the Cerberus Dashboard to:
## Summary
1. Rename "WAF" to "Coraza" (consistent with how CrowdSec is named - the card uses the product name)
2. Remove the Mode and Rule Set dropdowns from the card (these are handled on the config page)
This plan addressed two issues with the Rate Limiting feature:
## Reference: CrowdSec Card Pattern
1. **Backend Bug Fixed:** The `Upsert()` function in `security_service.go` now properly
saves all rate limiting fields (requests/sec, burst, window).
The CrowdSec card naming convention shows that we use the **product name** (CrowdSec) rather than generic terms. Similarly, WAF should become "Coraza" since Coraza is the underlying product.
2. **UX Improvements Added:**
- Status badge on Rate Limiting card (Security dashboard)
- "Currently Active" summary card on Rate Limiting config page
**CrowdSec Card Structure:**
## Files Changed
- Title: "CrowdSec" (not "IPS" or "Intrusion Prevention System")
- Simple enabled/disabled status
- Config button navigates to `/security/crowdsec` for detailed configuration
- `backend/internal/services/security_service.go` - Fixed field persistence
- `backend/internal/services/security_service_test.go` - Added test coverage
- `frontend/src/pages/Security.tsx` - Added status badge
- `frontend/src/pages/RateLimiting.tsx` - Added active config summary
- `frontend/src/pages/__tests__/RateLimiting.spec.tsx` - Added tests
**Current WAF Card Issues:**
## Documentation
- Title: "WAF (Coraza)" - should just be "Coraza"
- Contains Mode and Rule Set dropdowns (should be on config page only)
- Inconsistent with CrowdSec card simplicity
See [features.md](../features.md#rate-limiting) for user-facing documentation.
## Files to Modify
---
### 1. Frontend: Security Dashboard Page
**File:** `frontend/src/pages/Security.tsx`
**Changes Required:**
| Line(s) | Current Text/Code | New Text/Code | Notes |
|---------|------------------|---------------|-------|
| 171 | `Cerberus powers CrowdSec, WAF, ACLs, and Rate Limiting.` | `Cerberus powers CrowdSec, Coraza, ACLs, and Rate Limiting.` | Info banner text |
| 317 | `{/* WAF - Layer 3: Request Inspection */}` | `{/* Coraza - Layer 3: Request Inspection */}` | Comment update |
| 321 | `<h3 className="text-sm font-medium text-white">WAF (Coraza)</h3>` | `<h3 className="text-sm font-medium text-white">Coraza</h3>` | Card title |
| 337-340 | Protection text using "WAF" terminology | Keep as-is | Still valid for "Coraza" |
| **341-379** | **WAF Mode and Rule Set dropdowns (entire block)** | **REMOVE** | Delete the entire conditional block that renders dropdowns when WAF is enabled |
| 383 | `onClick={() => navigate('/security/waf')}` | Keep same path | Route stays the same, just config page |
| 385 | `{status.waf.enabled ? 'Manage Rule Sets' : 'Configure'}` | `{status.waf.enabled ? 'Configure' : 'Configure'}` or just `Configure` | Simplify button text |
**Specific Block to Remove (Lines ~341-379):**
```tsx
{status.waf.enabled && (
<div className="mt-3 space-y-3">
<div>
<label className="text-xs text-gray-400 block mb-1">WAF Mode</label>
<select
value={securityConfig?.config?.waf_mode || 'block'}
onChange={(e) => updateSecurityConfigMutation.mutate({ name: 'default', waf_mode: e.target.value })}
className="w-full bg-gray-800 border border-gray-700 rounded px-2 py-1 text-sm text-white"
data-testid="waf-mode-select"
>
<option value="block">Block (deny malicious requests)</option>
<option value="monitor">Monitor (log only, don't block)</option>
</select>
</div>
<div>
<label className="text-xs text-gray-400 block mb-1">Active Rule Set</label>
<select
value={securityConfig?.config?.waf_rules_source || ''}
onChange={(e) => updateSecurityConfigMutation.mutate({ name: 'default', waf_rules_source: e.target.value || undefined })}
className="w-full bg-gray-800 border border-gray-700 rounded px-2 py-1 text-sm text-white"
data-testid="waf-ruleset-select"
>
<option value="">None (all rule sets)</option>
{ruleSetsData?.rulesets?.map((rs) => (
<option key={rs.id} value={rs.name}>
{rs.name} ({rs.mode === 'blocking' ? 'blocking' : 'detection'})
</option>
))}
</select>
{(!ruleSetsData?.rulesets || ruleSetsData.rulesets.length === 0) && (
<p className="text-xs text-yellow-500 mt-1">
No rule sets configured. Add one below.
</p>
)}
</div>
</div>
)}
```
### 2. Frontend: Layout Navigation
**File:** `frontend/src/components/Layout.tsx`
**Changes Required:**
| Line | Current Text | New Text |
|------|-------------|----------|
| 70 | `{ name: 'WAF (Coraza)', path: '/security/waf', icon: '🛡️' }` | `{ name: 'Coraza', path: '/security/waf', icon: '🛡️' }` |
### 3. Test Files to Update
#### 3.1 Security Page Tests
**File:** `frontend/src/pages/__tests__/Security.spec.tsx`
**Changes Required:**
| Test Name | Change Description |
|-----------|-------------------|
| `shows WAF mode selector when WAF is enabled` | **DELETE entire test** - Mode selector no longer on dashboard |
| `shows WAF ruleset selector with available rulesets` | **DELETE entire test** - Ruleset selector no longer on dashboard |
| `calls updateSecurityConfig when WAF mode is changed` | **DELETE entire test** - No mode selector on dashboard |
| `calls updateSecurityConfig when WAF ruleset is changed` | **DELETE entire test** - No ruleset selector on dashboard |
| `shows warning when no rulesets are configured` | **DELETE entire test** - Warning no longer on dashboard |
| `displays correct WAF threat protection summary when enabled` | Keep but update any "WAF" string references if needed |
| `does not show WAF controls when WAF is disabled` | **DELETE entire test** - Controls never shown on dashboard now |
**Tests to delete (Lines ~189-344):**
- `it('shows WAF mode selector when WAF is enabled', ...)`
- `it('shows WAF ruleset selector with available rulesets', ...)`
- `it('calls updateSecurityConfig when WAF mode is changed', ...)`
- `it('calls updateSecurityConfig when WAF ruleset is changed', ...)`
- `it('shows warning when no rulesets are configured', ...)`
- `it('does not show WAF controls when WAF is disabled', ...)`
Keep:
- `it('displays correct WAF threat protection summary when enabled', ...)` - This tests the protection description text, not the dropdowns
#### 3.2 Security Audit Tests
**File:** `frontend/src/pages/__tests__/Security.audit.test.tsx`
**Changes Required:**
| Line | Current Text | New Text |
|------|-------------|----------|
| 287 | `expect(screen.getByText('WAF (Coraza)')).toBeInTheDocument()` | `expect(screen.getByText('Coraza')).toBeInTheDocument()` |
| 306-315 | `it('WAF controls have proper test IDs when enabled', ...)` | **DELETE entire test** - WAF controls no longer on dashboard |
| 344 | `expect(cardNames).toEqual(['CrowdSec', 'Access Control', 'WAF (Coraza)', 'Rate Limiting', 'Live Security Logs'])` | `expect(cardNames).toEqual(['CrowdSec', 'Access Control', 'Coraza', 'Rate Limiting', 'Live Security Logs'])` |
### 4. WAF Config Page (NO CHANGES NEEDED)
**File:** `frontend/src/pages/WafConfig.tsx`
The WAF config page already properly uses "WAF" terminology in its title ("WAF Configuration") and references "Coraza" where appropriate. Since this is the configuration page, the Mode and Rule Set selections should remain here. **No changes required.**
### 5. WAF Config Tests (NO CHANGES NEEDED)
**File:** `frontend/src/pages/__tests__/WafConfig.spec.tsx`
These tests test the WafConfig page which is unaffected. **No changes required.**
## Summary of Changes
| File | Change Type | Description |
|------|-------------|-------------|
| `frontend/src/pages/Security.tsx` | Modify | Rename "WAF" → "Coraza", remove Mode/RuleSet dropdowns |
| `frontend/src/components/Layout.tsx` | Modify | Rename nav item "WAF (Coraza)" → "Coraza" |
| `frontend/src/pages/__tests__/Security.spec.tsx` | Delete tests | Remove 6 tests for WAF dropdown controls |
| `frontend/src/pages/__tests__/Security.audit.test.tsx` | Modify | Update card name assertions, remove dropdown test |
## API Changes
**None required.** This is purely a frontend UI change. The backend API endpoints, types, and data structures remain unchanged.
## Type Definition Changes
**None required.** The SecurityStatus type and related interfaces don't need modification.
## Text/Label Changes Summary
| Location | From | To |
|----------|------|-----|
| Card title (Security.tsx) | `WAF (Coraza)` | `Coraza` |
| Nav sidebar (Layout.tsx) | `WAF (Coraza)` | `Coraza` |
| Info banner (Security.tsx) | `CrowdSec, WAF, ACLs` | `CrowdSec, Coraza, ACLs` |
| Comment (Security.tsx) | `/* WAF - Layer 3 */` | `/* Coraza - Layer 3 */` |
| Test assertions | `WAF (Coraza)` | `Coraza` |
## Button Simplification
The button text on the Coraza card should be simplified:
- **Current:** `{status.waf.enabled ? 'Manage Rule Sets' : 'Configure'}`
- **New:** `Configure` (always)
This matches the CrowdSec card pattern which just shows "Config" regardless of enabled state.
## Implementation Order
1. Update `Security.tsx`:
- Change card title from "WAF (Coraza)" to "Coraza"
- Update banner text
- Update comment
- Remove the dropdown controls block
- Simplify button text
2. Update `Layout.tsx`:
- Change nav item name
3. Update test files:
- `Security.spec.tsx`: Remove obsolete tests
- `Security.audit.test.tsx`: Update assertions, remove dropdown test
4. Run tests to verify: `cd frontend && npm test`
5. Run type check: `cd frontend && npm run type-check`
6. Run pre-commit checks
## Verification Checklist
- [ ] Card title shows "Coraza" (not "WAF (Coraza)")
- [ ] Nav sidebar shows "Coraza"
- [ ] No Mode dropdown on dashboard card
- [ ] No Rule Set dropdown on dashboard card
- [ ] "Configure" button navigates to `/security/waf` config page
- [ ] Mode/Rule Set controls still available on `/security/waf` config page
- [ ] All tests pass
- [ ] TypeScript compiles without errors
- [ ] Pre-commit hooks pass

## Rate Limiting Implementation Verification
### Files Verified
| File | Purpose | Status |
|------|---------|--------|
| [backend/internal/models/security_config.go](backend/internal/models/security_config.go#L21-L24) | Rate limit model fields | ✅ |
| [backend/internal/caddy/config.go](backend/internal/caddy/config.go#L857-L874) | Caddy rate_limit handler generation | ✅ |
| [backend/internal/services/security_service.go](backend/internal/services/security_service.go) | Rate limit persistence | ✅ |
| [frontend/src/pages/RateLimiting.tsx](frontend/src/pages/RateLimiting.tsx) | UI component | ✅ |
### Model Fields Confirmed
```go
type SecurityConfig struct {
RateLimitEnable bool `json:"rate_limit_enable"`
RateLimitBurst int `json:"rate_limit_burst"`
RateLimitRequests int `json:"rate_limit_requests"`
RateLimitWindowSec int `json:"rate_limit_window_sec"`
}
```
### Pipeline Order Verified
The security pipeline correctly positions rate limiting:
1. CrowdSec (IP reputation)
2. WAF (Coraza)
3. **Rate Limiting** ← Position confirmed
4. ACL (Access Control Lists)
5. Headers/Vars
6. Reverse Proxy
---
## Recommendations
### Immediate Actions
None required for Rate Limiting changes.
### Technical Debt
1. **SMTPSettings.test.tsx flaky test** - Consider adding longer waitFor timeout or stabilizing the async assertion pattern
- Location: [frontend/src/pages/__tests__/SMTPSettings.test.tsx#L60](frontend/src/pages/__tests__/SMTPSettings.test.tsx#L60)
- Priority: Low (not blocking)
### Code Quality Notes
- Coverage maintained above 85% threshold ✅
- No new linter warnings introduced ✅
- All Rate Limiting specific tests passing ✅
---
## Conclusion
The Rate Limiting bug fix changes pass all quality checks. The single test failure identified is a pre-existing flaky test in the SMTP settings module, unrelated to Rate Limiting functionality. All Rate Limiting specific tests (9 frontend tests + backend integration tests) pass successfully.
**Approval Status:** ✅ **APPROVED FOR MERGE**
