+# Cerberus Full Integration Testing Plan
+
+**Version:** 1.0
+**Date:** 2025-12-12
+**Issue:** #319
+**Status:** 🔵 READY FOR TESTING
+
+---
+
+## 1. Overview
+
+This plan tests all Cerberus security features **working together** to ensure no conflicts or ordering issues when multiple features are enabled simultaneously.
+
+### 1.1 Features Under Test
+
+| Feature | Handler Name | Purpose |
+|---------|--------------|---------|
+| Security Decisions | `subroute` (IP block) | Manual IP blocks via API |
+| CrowdSec | `crowdsec` | IP reputation bouncer |
+| WAF | `waf` (Coraza) | Payload inspection |
+| Rate Limiting | `rate_limit` | Volume abuse prevention |
+| ACL | `subroute` (IP/Geo) | Static allow/deny lists |
+
+### 1.2 Pipeline Order (from `config.go`)
+
+The security handlers execute in this order per-route:
+
+```
+Request → [Security Decisions] → [CrowdSec] → [WAF] → [Rate Limit] → [ACL] → [Proxy]
+```
+
+**Source:** [backend/internal/caddy/config.go#L216-290](../../backend/internal/caddy/config.go)
+
+---
+
+## 2. Test Environment Setup
+
+### 2.1 Prerequisites
+
+- Docker with `charon:local` image built
+- Access to container ports: 8080 (API), 80/443 (proxy), 2019 (Caddy admin)
+
+### 2.2 Environment Variables
+
+```bash
+# Enable all security features
+export CERBERUS_SECURITY_CERBERUS_ENABLED=true
+export CERBERUS_SECURITY_WAF_MODE=block
+export CERBERUS_SECURITY_CROWDSEC_MODE=disabled  # or local if LAPI available
+export CERBERUS_SECURITY_RATELIMIT_MODE=enabled
+export CERBERUS_SECURITY_ACL_ENABLED=true
+```
+
+### 2.3 Container Startup
+
+```bash
+docker run -d --name charon-cerberus-test \
+  -p 8080:8080 -p 80:80 -p 2019:2019 \
+  -e CHARON_ENV=development \
+  -e CERBERUS_SECURITY_CERBERUS_ENABLED=true \
+  -e CERBERUS_SECURITY_WAF_MODE=block \
+  -e CERBERUS_SECURITY_RATELIMIT_MODE=enabled \
+  -e CERBERUS_SECURITY_ACL_ENABLED=true \
+  charon:local
+```
+
+### 2.4 Test Proxy Host Creation
+
+```bash
+# Login and create test proxy host
+curl -s -X POST http://localhost:8080/api/v1/proxy-hosts \
+  -H "Content-Type: application/json" \
+  -b cookies.txt \
+  -d '{
+    "domain_names": "cerberus.test.local",
+    "forward_scheme": "http",
+    "forward_host": "httpbin.org",
+    "forward_port": 80,
+    "enabled": true
+  }'
+```
+
+---
+
+## 3. Test Cases
+
+### TC-1: Enable All Features Simultaneously
+
+**Objective:** Verify all Cerberus features can be enabled without startup errors.
+
+**Steps:**
+
+1. Start container with all env vars set
+2. Wait for Caddy reload
+3. Query `/api/v1/security/status` to confirm all features enabled
+
+**Verification:**
+
+```bash
+# Check security status
+curl -s http://localhost:8080/api/v1/security/status | jq
+
+# Expected:
+# {
+#   "enabled": true,
+#   "waf_mode": "block",
+#   "crowdsec_mode": "local|disabled",
+#   "acl_enabled": true,
+#   "rate_limit_enabled": true
+# }
+```
+
+**Pass Criteria:**
+
+- [ ] Container starts without errors
+- [ ] All features report enabled in status
+- [ ] No Caddy config validation errors in logs
+
+---
+
+### TC-2: Verify Pipeline Handler Order
+
+**Objective:** Confirm security handlers are in correct order in Caddy config.
+
+**Steps:**
+
+1. Query Caddy admin API for running config
+2. Parse handler order for the test route
+3. Verify order matches expected: Decisions → CrowdSec → WAF → Rate Limit → ACL → Proxy
+
+**Verification:**
+
+```bash
+# Extract handler order from Caddy config
+curl -s http://localhost:2019/config | python3 -c "
+import sys, json
+config = json.load(sys.stdin)
+servers = config.get('apps', {}).get('http', {}).get('servers', {})
+for name, server in servers.items():
+    for route in server.get('routes', []):
+        hosts = []
+        for m in route.get('match', []):
+            hosts.extend(m.get('host', []))
+        if 'cerberus.test.local' in hosts:
+            handlers = [h.get('handler') for h in route.get('handle', [])]
+            print('Handler order:', handlers)
+"
+```
+
+**Expected Order:**
+
+1. `subroute` (if decisions exist)
+2. `crowdsec` (if enabled)
+3. `waf` (if enabled)
+4. `rate_limit` or `subroute` (rate limit wrapper)
+5. `subroute` (ACL if enabled)
+6. `reverse_proxy`
+
+**Pass Criteria:**
+
+- [ ] Security handlers appear before `reverse_proxy`
+- [ ] Order matches expected pipeline
+
+---
+
+### TC-3: WAF Blocking Doesn't Break Rate Limiter
+
+**Objective:** Ensure WAF-blocked requests don't consume rate limit quota incorrectly.
+
+**Steps:**
+
+1. Configure rate limit: 5 requests / 30 seconds
+2. Send 3 malicious requests (WAF blocks)
+3. Send 5 legitimate requests
+4. Verify all 5 legitimate requests succeed (200)
+
+**Verification:**
+
+```bash
+# Configure rate limit
+curl -s -X POST http://localhost:8080/api/v1/security/config \
+  -H "Content-Type: application/json" \
+  -b cookies.txt \
+  -d '{
+    "rate_limit_requests": 5,
+    "rate_limit_window_sec": 30
+  }'
+
+sleep 3
+
+# 3 malicious requests (should be blocked by WAF with 403)
+for i in 1 2 3; do
+  CODE=$(curl -s -o /dev/null -w "%{http_code}" \
+    -H "Host: cerberus.test.local" \
+    "http://localhost/get?q=<script>alert(1)</script>")
+  echo "Malicious $i: HTTP $CODE (expect 403)"
+done
+
+# 5 legitimate requests (should all succeed)
+for i in 1 2 3 4 5; do
+  CODE=$(curl -s -o /dev/null -w "%{http_code}" \
+    -H "Host: cerberus.test.local" \
+    "http://localhost/get")
+  echo "Legitimate $i: HTTP $CODE (expect 200)"
+done
+```
+
+**Pass Criteria:**
+
+- [ ] All malicious requests return 403 (WAF block)
+- [ ] All 5 legitimate requests return 200 (not rate limited)
+
+---
+
+### TC-4: Rate Limiter Doesn't Break CrowdSec Decisions
+
+**Objective:** Verify CrowdSec decisions are enforced even if rate limit not exceeded.
+
+**Steps:**
+
+1. Create a manual security decision blocking a test IP
+2. Send request from that IP (via X-Forwarded-For if needed)
+3. Verify request is blocked with 403 before rate limit check
+
+**Verification:**
+
+```bash
+# Add manual IP block decision
+curl -s -X POST http://localhost:8080/api/v1/security/decisions \
+  -H "Content-Type: application/json" \
+  -b cookies.txt \
+  -d '{
+    "ip": "203.0.113.50",
+    "action": "block",
+    "reason": "Test block for TC-4"
+  }'
+
+sleep 3
+
+# Request should be blocked immediately (decisions come first)
+CODE=$(curl -s -o /dev/null -w "%{http_code}" \
+  -H "Host: cerberus.test.local" \
+  -H "X-Forwarded-For: 203.0.113.50" \
+  "http://localhost/get")
+echo "Blocked IP request: HTTP $CODE (expect 403)"
+```
+
+**Pass Criteria:**
+
+- [ ] Request from blocked IP returns 403
+- [ ] Response body contains "Blocked by security decision"
+
+---
+
+### TC-5: Legitimate Traffic Flows Through All Layers
+
+**Objective:** Confirm clean traffic passes through all security layers to upstream.
+
+**Steps:**
+
+1. Enable all features with permissive config
+2. Send 10 legitimate requests
+3. Verify all return 200 with upstream response
+
+**Verification:**
+
+```bash
+echo "=== Testing legitimate traffic flow ==="
+
+# Send 10 legitimate requests
+SUCCESS=0
+for i in $(seq 1 10); do
+  BODY=$(curl -s -H "Host: cerberus.test.local" "http://localhost/get")
+  if echo "$BODY" | grep -q "httpbin.org"; then
+    ((SUCCESS++))
+    echo "Request $i: ✓ Success (reached upstream)"
+  else
+    echo "Request $i: ✗ Failed"
+  fi
+done
+
+echo "Total successful: $SUCCESS/10"
+```
+
+**Pass Criteria:**
+
+- [ ] All 10 requests return 200
+- [ ] Response body contains upstream (httpbin) content
+- [ ] No unexpected 403/429 responses
+
+---
+
+### TC-6: Basic Latency Benchmark
+
+**Objective:** Measure latency overhead when all Cerberus features are enabled.
+
+**Steps:**
+
+1. Measure baseline latency (Cerberus disabled)
+2. Enable all Cerberus features
+3. Measure latency with full security stack
+4. Calculate overhead percentage
+
+**Verification:**
+
+```bash
+# Baseline (security disabled)
+echo "=== Baseline (Cerberus disabled) ==="
+BASELINE=$(curl -s -o /dev/null -w "%{time_total}" \
+  -H "Host: cerberus.test.local" "http://localhost/get")
+echo "Baseline: ${BASELINE}s"
+
+# With full security (already enabled)
+echo "=== With all Cerberus features ==="
+SECURED=$(curl -s -o /dev/null -w "%{time_total}" \
+  -H "Host: cerberus.test.local" "http://localhost/get")
+echo "Secured: ${SECURED}s"
+
+# Calculate overhead (requires bc)
+# OVERHEAD=$(echo "scale=2; ($SECURED - $BASELINE) / $BASELINE * 100" | bc)
+# echo "Overhead: ${OVERHEAD}%"
+```
+
+**Load Test (10 concurrent, 100 total):**
+
+```bash
+# Using Apache Bench (ab)
+ab -n 100 -c 10 -H "Host: cerberus.test.local" http://localhost/get
+
+# Or using hey (Go HTTP load tester)
+hey -n 100 -c 10 -host "cerberus.test.local" http://localhost/get
+```
+
+**Pass Criteria:**
+
+- [ ] Average latency overhead < 50ms per request
+- [ ] 95th percentile latency < 500ms
+- [ ] No request failures under load
+
+---
+
+## 4. Integration Script Outline
+
+Create `scripts/cerberus_integration.sh`:
+
+```bash
+#!/usr/bin/env bash
+set -euo pipefail
+
+# Integration test for full Cerberus security stack
+# Tests all features enabled simultaneously
+
+PROJECT_ROOT="$(cd "$(dirname "${BASH_SOURCE[0]}")/.." && pwd)"
+cd "$PROJECT_ROOT"
+
+CONTAINER_NAME="charon-cerberus-test"
+TEST_DOMAIN="cerberus.test.local"
+
+# Cleanup function
+cleanup() {
+    echo "Cleaning up..."
+    docker rm -f ${CONTAINER_NAME} 2>/dev/null || true
+}
+trap cleanup EXIT
+
+# Build and start
+echo "=== Building and starting Charon with full Cerberus ==="
+docker build -t charon:local .
+docker run -d --name ${CONTAINER_NAME} \
+  -p 8380:8080 -p 8381:80 -p 2319:2019 \
+  -e CHARON_ENV=development \
+  -e CERBERUS_SECURITY_CERBERUS_ENABLED=true \
+  -e CERBERUS_SECURITY_WAF_MODE=block \
+  -e CERBERUS_SECURITY_RATELIMIT_MODE=enabled \
+  -e CERBERUS_SECURITY_ACL_ENABLED=true \
+  charon:local
+
+# Wait for startup
+sleep 10
+
+# TC-1: Check status
+echo "=== TC-1: Verifying all features enabled ==="
+STATUS=$(curl -s http://localhost:8380/api/v1/security/status)
+echo "$STATUS" | grep -q '"enabled":true' && echo "✓ Cerberus enabled" || exit 1
+
+# TC-2: Check handler order
+echo "=== TC-2: Verifying handler order ==="
+# ... (parse Caddy config as shown in TC-2)
+
+# TC-3: WAF + Rate Limit interaction
+echo "=== TC-3: WAF blocking vs rate limiting ==="
+# ... (implement test)
+
+# TC-5: Legitimate traffic
+echo "=== TC-5: Legitimate traffic flow ==="
+# ... (implement test)
+
+echo ""
+echo "==========================================="
+echo "ALL CERBERUS INTEGRATION TESTS PASSED"
+echo "==========================================="
+```
+
+---
+
+## 5. Go Test Wrapper
+
+Create `backend/integration/cerberus_integration_test.go`:
+
+```go
+//go:build integration
+// +build integration
+
+package integration
+
+import (
+    "context"
+    "os/exec"
+    "strings"
+    "testing"
+    "time"
+)
+
+func TestCerberusIntegration(t *testing.T) {
+    t.Parallel()
+
+    ctx, cancel := context.WithTimeout(context.Background(), 15*time.Minute)
+    defer cancel()
+
+    cmd := exec.CommandContext(ctx, "bash", "../scripts/cerberus_integration.sh")
+    cmd.Dir = ".."
+
+    out, err := cmd.CombinedOutput()
+    t.Logf("cerberus_integration output:\n%s", string(out))
+
+    if err != nil {
+        t.Fatalf("cerberus integration failed: %v", err)
+    }
+
+    if !strings.Contains(string(out), "ALL CERBERUS INTEGRATION TESTS PASSED") {
+        t.Fatalf("unexpected output: final success message not found")
+    }
+}
+```
+
+---
+
+## 6. VS Code Task
+
+Add to `.vscode/tasks.json`:
+
+```json
+{
+  "label": "Cerberus: Run Full Integration Script",
+  "type": "shell",
+  "command": "bash",
+  "args": ["./scripts/cerberus_integration.sh"],
+  "group": "test"
+},
+{
+  "label": "Cerberus: Run Full Integration Go Test",
+  "type": "shell",
+  "command": "sh",
+  "args": [
+    "-c",
+    "cd backend && go test -tags=integration ./integration -run TestCerberusIntegration -v"
+  ],
+  "group": "test"
+}
+```
+
+---
+
+## 7. Expected Issues & Mitigations
+
+| Issue | Likelihood | Mitigation |
+|-------|------------|------------|
+| Handler order wrong | Low | Unit test in `config_test.go` covers this |
+| WAF blocks counting as rate limit | Medium | WAF returns 403 before rate_limit handler runs |
+| ACL conflicts with decisions | Low | Both use subroutes, evaluated in order |
+| CrowdSec LAPI unavailable | High | Test with `crowdsec_mode=disabled` first |
+| High latency under load | Medium | Benchmark and profile if > 100ms overhead |
+
+---
+
+## 8. Success Criteria
+
+All test cases pass:
+
+- [ ] **TC-1:** All features enable without errors
+- [ ] **TC-2:** Handler order verified in Caddy config
+- [ ] **TC-3:** WAF blocks don't consume rate limit
+- [ ] **TC-4:** Decisions enforced before rate limit
+- [ ] **TC-5:** 100% legitimate traffic success rate
+- [ ] **TC-6:** Latency overhead < 50ms average
