### CrowdSec Integration Commands
**⚠️ Note**: IP management is now automated via CrowdSec webhook integration. Manual commands are for monitoring and emergency use only.
**View Current Blocked IPs:**
```bash
# View current blocked IPs (Updated IP Set ID)
aws wafv2 get-ip-set --scope CLOUDFRONT --region us-east-1 \
--id a9e47946-c186-4b28-83a8-fe3aeb9c296b \
--name aws-cf-dev-blocked-ips \
--query 'IPSet.Addresses'
```
**Test CrowdSec Webhook:**
```bash
# Test webhook endpoint
curl -X POST https://8zdmpjfnhh.execute-api.us-east-1.amazonaws.com/dev/webhook \
-H "Content-Type: application/json" \
-H "User-Agent: CrowdSec/1.7.0" \
-d '[{"uuid":"test","decisions":[{"value":"1.2.3.4","type":"ban","action":"add"}]}]'
```
**Monitor CrowdSec Container:**
```bash
# Check CrowdSec status
incus exec crowdsec -- cscli metrics
# View current decisions
incus exec crowdsec -- cscli decisions list
# Test notifications
incus exec crowdsec -- cscli notifications test aws-waf
```
**Lambda Function Monitoring:**
```bash
# Check Lambda logs
aws logs tail /aws/lambda/aws-cf-dev-crowdsec-waf-updater --follow
# Test Lambda directly
aws lambda invoke --function-name aws-cf-dev-crowdsec-waf-updater response.json
```
### WAF Monitoring
**Check WAF Metrics:**
```bash
# Check blocked requests
aws cloudwatch get-metric-statistics --namespace AWS/WAFV2 \
--metric-name BlockedRequests \
--dimensions Name=WebACL,Value=aws-cf-dev-waf Name=Rule,Value=BlockedIPsRule \
--start-time $(date -u -d '1 hour ago' +%Y-%m-%dT%H:%M:%S) \
--end-time $(date -u +%Y-%m-%dT%H:%M:%S) \
--period 300 --statistics Sum
# Check rate limited requests
aws cloudwatch get-metric-statistics --namespace AWS/WAFV2 \
--metric-name BlockedRequests \
--dimensions Name=WebACL,Value=aws-cf-dev-waf Name=Rule,Value=RateLimitRule \
--start-time $(date -u -d '1 hour ago' +%Y-%m-%dT%H:%M:%S) \
--end-time $(date -u +%Y-%m-%dT%H:%M:%S) \
--period 300 --statistics Sum
```

## WAF Troubleshooting History
### Issue Resolution (2025-09-09)
**Problem**: WAF IP blocking was not functioning despite proper configuration.
**Root Cause Analysis:**
1. **IP Set ID Mismatch**: Commands referenced old IP Set ID (`c43ff364-f3e2-43c7-8462-8fae20599d8d`) instead of actual ID
2. **CloudFront Deployment State**: Distribution was in "InProgress" status preventing WAF changes from taking effect
3. **Configuration Synchronization**: WAF and CloudFront association was not properly synchronized
**Resolution Method:**
- Complete infrastructure recreation using `tofu destroy` and `tofu apply`
- All resources recreated with fresh IDs and proper associations
- WAF rules now properly configured with correct IP Set references
**Current Status:**
- ✅ WAF properly associated with CloudFront (`EATJ1HDQU8V51`)
- ✅ IP blocking rules functional (Priority 1: BlockedIPsRule)
- ✅ Rate limiting active (10,000 requests/5min per IP)
- ✅ AWS managed rule sets enabled (Common + Known Bad Inputs)
- ✅ Test IP blocking verified: `1.2.3.4/32`, `61.77.18.91/32`
**Key Commands for Manual IP Management:**
```bash
# Add IP to blocked list
aws wafv2 update-ip-set --scope=CLOUDFRONT --region=us-east-1 \
--id a9e47946-c186-4b28-83a8-fe3aeb9c296b \
--name aws-cf-dev-blocked-ips \
--addresses "IP1/32" "IP2/32" \
--lock-token $(aws wafv2 get-ip-set --scope=CLOUDFRONT --region=us-east-1 \
--id a9e47946-c186-4b28-83a8-fe3aeb9c296b \
--name aws-cf-dev-blocked-ips --query 'LockToken' --output text)
# Verify WAF-CloudFront association
aws cloudfront get-distribution --id EATJ1HDQU8V51 \
--query 'Distribution.DistributionConfig.WebACLId' --output text
# Check current blocked IPs
aws wafv2 get-ip-set --scope=CLOUDFRONT --region=us-east-1 \
--id a9e47946-c186-4b28-83a8-fe3aeb9c296b \
--name aws-cf-dev-blocked-ips --query 'IPSet.Addresses'
```
**Note**: WAF rule changes may take up to 15 minutes to propagate across CloudFront edge locations.

## ⚙️ 중요 설정 내용 ## 🔒 2단계: CrowdSec 컨테이너 설정
### terraform.tfvars 핵심 설정 ### 컨테이너 생성
```hcl ```bash
# Origin 설정 (매우 중요) # 새 Ubuntu 컨테이너 생성
origin_domain = "origin.servidor.it.com" incus launch ubuntu:24.04 crowdsec
origin_protocol_policy = "http-only" # HTTPS 사용 시 504 에러! incus exec crowdsec -- apt update
# CloudFront 설정
viewer_protocol_policy = "redirect-to-https"
price_class = "PriceClass_100"
# 보안 설정
enable_waf = true
# 로깅 설정
enable_cloudfront_logging = true
cloudfront_logs_bucket = "aws-cf-cloudfront-logs-535294143817"
# 비활성화된 기능 (권한/제한 사항)
create_route53_records = false # CAA 제한으로 비활성화
create_acm_certificate = false # CloudFront 기본 인증서 사용
enable_cloudformation_stack = false # CloudFormation 권한 없음
``` ```
## 🔧 문제 해결 히스토리 ### CrowdSec 설치
```bash
# CrowdSec 설치
incus exec crowdsec -- curl -s https://install.crowdsec.net | sh
### 1. 504 Gateway Timeout 해결 ✅ # 서비스 상태 확인
**문제**: CloudFront가 origin 서버에 연결할 수 없음 incus exec crowdsec -- systemctl status crowdsec
**원인**: origin.servidor.it.com이 HTTP(80)만 지원하는데 HTTPS(443)로 연결 시도
**해결**:
```hcl
origin_protocol_policy = "http-only"
``` ```
### 2. ACM 인증서 CAA 제한 ✅ ### 보안 컬렉션 설치
**문제**: *.servidor.it.com 도메인에 대한 ACM 인증서 발급 실패 ```bash
**원인**: CAA DNS 레코드가 AWS 인증서 발급을 제한 # Nginx Proxy Manager 컬렉션 설치
**해결**: CloudFront 기본 인증서 사용 incus exec crowdsec -- cscli collections install crowdsecurity/nginx-proxy-manager
```hcl
create_acm_certificate = false # 설치된 컬렉션 확인
viewer_certificate { incus exec crowdsec -- cscli collections list
cloudfront_default_certificate = true
# 설정 적용
incus exec crowdsec -- systemctl reload crowdsec
```
## 🔗 3단계: 웹훅 통합 설정
### 알림 설정 파일 생성
```bash
incus exec crowdsec -- tee /etc/crowdsec/notifications/aws-waf.yaml << 'EOF'
type: http
name: aws-waf
log_level: info
url: https://8zdmpjfnhh.execute-api.us-east-1.amazonaws.com/dev/webhook
method: POST
headers:
Content-Type: application/json
User-Agent: CrowdSec/1.7.0
timeout: 10s
format: |
{{ .|toJson }}
EOF
```
### 프로필 설정
```bash
incus exec crowdsec -- tee /etc/crowdsec/profiles.yaml << 'EOF'
name: aws_waf_profile
filters:
- Alert.Remediation == true && Alert.GetScenario() startsWith "crowdsecurity/"
notifications:
- aws-waf
on_success: break
EOF
```
### CrowdSec 재시작
```bash
incus exec crowdsec -- systemctl restart crowdsec
```
## 🧪 4단계: 통합 테스트
### 웹훅 엔드포인트 테스트
```bash
curl -X POST https://8zdmpjfnhh.execute-api.us-east-1.amazonaws.com/dev/webhook \
-H "Content-Type: application/json" \
-H "User-Agent: CrowdSec/1.7.0" \
-d '[{
"uuid": "test-123",
"decisions": [{
"value": "192.168.1.100",
"type": "ban",
"action": "add"
}]
}]'
```
**예상 응답:**
```json
{
"success": true,
"message": "WAF IP Set updated successfully",
"ips_added": ["192.168.1.100"],
"ips_removed": [],
"total_ips": 1
} }
``` ```
### 3. DynamoDB State Locking 권한 ✅ ### WAF IP Set 확인
**문제**: Terraform state locking을 위한 DynamoDB 테이블 생성/접근 불가
**해결**: S3만 사용 (1인 개발 시 충분)
```hcl
backend "s3" {
bucket = "aws-cf-terraform-state-535294143817"
key = "aws-cf/terraform.tfstate"
# dynamodb_table = "terraform-state-lock" # 비활성화
}
```
### 4. 중복 CloudFront Distribution 정리 ✅
**문제**: 여러 배포 시도로 3개의 distribution 생성
**해결**:
- E18GW141CX7I8C - 비활성화 중 (삭제 예정)
- E32FD742KMW2YY - 비활성화 중 (삭제 예정)
- E1XR8P4ENGP8RU - 현재 사용 중 ✅
### 5. WAF 권한 문제 ✅
**초기 문제**: WAFv2 권한 없다고 오류 발생
**해결**: AWSWAFFullAccess 정책에 wafv2:* 권한 포함되어 있음 확인
## 📊 모니터링 및 관리
### 상태 확인 명령어
```bash ```bash
# CloudFront 상태 aws wafv2 get-ip-set --scope CLOUDFRONT --region us-east-1 \
aws cloudfront get-distribution --id E1XR8P4ENGP8RU \ --id a9e47946-c186-4b28-83a8-fe3aeb9c296b \
--query 'Distribution.Status' --output text --name aws-cf-dev-blocked-ips \
--query 'IPSet.Addresses'
# WAF 연결 확인
aws cloudfront get-distribution --id E1XR8P4ENGP8RU \
--query 'Distribution.DistributionConfig.WebACLId' --output text
# 로그 확인
aws s3 ls s3://aws-cf-cloudfront-logs-535294143817/cloudfront-logs/ --recursive
# State 파일 확인
aws s3 ls s3://aws-cf-terraform-state-535294143817/aws-cf/
``` ```
### 성능 테스트 ### IP 제거 테스트
```bash ```bash
# CloudFront 응답 확인 curl -X POST https://8zdmpjfnhh.execute-api.us-east-1.amazonaws.com/dev/webhook \
curl -I https://dspki4yrh5oy1.cloudfront.net -H "Content-Type: application/json" \
-H "User-Agent: CrowdSec/1.7.0" \
# 출력 예시: -d '[{
# HTTP/2 200 "uuid": "test-456",
# content-type: text/html "decisions": [{
# x-cache: Miss from cloudfront (첫 요청) / Hit from cloudfront (캐시된 요청) "value": "192.168.1.100",
"type": "ban",
"action": "delete"
}]
}]'
``` ```
### 비활성화된 Distribution 삭제 (완전 비활성화 후) ### CrowdSec 알림 테스트
```bash ```bash
# 상태 확인 incus exec crowdsec -- cscli notifications test aws-waf
aws cloudfront list-distributions \
--query 'DistributionList.Items[*].[Id,Status,DistributionConfig.Enabled]' \
--output table
# 삭제 (Deployed 상태에서 Enabled=false 일 때)
aws cloudfront get-distribution-config --id E18GW141CX7I8C > dist-config.json
ETAG=$(jq -r '.ETag' dist-config.json)
aws cloudfront delete-distribution --id E18GW141CX7I8C --if-match $ETAG
``` ```
## 🔒 보안 고려사항 ## 📊 5단계: 모니터링 설정
1. **WAF 설정** ### Lambda 함수 로그 모니터링
- 현재 기본 AWS Managed Rules 사용 ```bash
- 필요시 커스텀 룰 추가 가능 # 실시간 로그 확인
- Rate limiting 조정 가능 (security.tf) aws logs tail /aws/lambda/aws-cf-dev-crowdsec-waf-updater --follow
2. **Origin 보안** # 특정 시간대 로그
- ⚠️ Origin이 HTTP만 지원하므로 CloudFront-Origin 간 트래픽 암호화 안됨 aws logs filter-log-events \
- 권장: Origin 서버에 HTTPS 지원 추가 --log-group-name /aws/lambda/aws-cf-dev-crowdsec-waf-updater \
--start-time $(date -d '1 hour ago' +%s)000
```
3. **로그 관리** ### CrowdSec 상태 모니터링
- CloudFront 로그 90일 자동 삭제 설정 ```bash
- 장기 보관 필요시 S3 lifecycle 수정 # 메트릭 확인
incus exec crowdsec -- cscli metrics
## 📝 향후 개선 사항 # 현재 차단 결정
incus exec crowdsec -- cscli decisions list
### 권한 획득 시 활성화 가능한 기능 # 허브 상태
1. **DynamoDB State Locking** incus exec crowdsec -- cscli hub list
- 팀 협업 시 필수 ```
- backend.tf에서 주석 해제
2. **Custom Domain with ACM** ### WAF 메트릭 확인
- CAA 레코드 수정 후 가능 ```bash
- terraform.tfvars에서 `create_acm_certificate = true` # 차단된 요청 확인
aws cloudwatch get-metric-statistics \
--namespace AWS/WAFV2 \
--metric-name BlockedRequests \
--dimensions Name=WebACL,Value=aws-cf-dev-waf Name=Rule,Value=BlockedIPsRule \
--start-time $(date -u -d '1 hour ago' +%Y-%m-%dT%H:%M:%S) \
--end-time $(date -u +%Y-%m-%dT%H:%M:%S) \
--period 300 --statistics Sum
```
3. **CloudFormation Stack** ## 🔧 문제 해결
- VPC 및 네트워킹 리소스 관리
- terraform.tfvars에서 `enable_cloudformation_stack = true`
### 성능 최적화 ### 일반적인 문제들
1. Cache Policy 최적화
2. Origin Request Policy 조정
3. CloudFront Edge Location 선택 (Price Class)

## 중요 설정 ---
### SSL 인증서 **Status**: ✅ Production Ready | **Last Updated**: 2025-09-09
이 설정은 **ACM(AWS Certificate Manager) 인증서**를 사용합니다:
- `servidor.it.com`과 `*.servidor.it.com` 도메인 지원
- 자동으로 us-east-1 리전에 ACM 인증서 생성
- DNS 검증을 통한 자동 인증서 발급
- Route53을 통한 자동 DNS 레코드 관리
- CloudFront와 완전 통합된 HTTPS 설정
### 캐시 정책
기본 제공되는 AWS 관리 정책:
- `4135ea2d-6df8-44a3-9df3-4b5a84be39ad` - CachingDisabled
- `725fe1d6-8a84-4f3e-8ab1-bc2d5bb10e12` - CachingOptimized
- `df3c6b6c-4e41-4d9c-a8c7-6b8b2b8e6b8b` - CachingOptimizedForUncompressedObjects
### 보안 고려사항
프로덕션 환경에서는:
- `ssh_allowed_cidrs`를 특정 IP로 제한
- WAF 활성화 (`enable_waf = true`)
- 적절한 캐시 정책 선택
- CloudTrail 및 CloudWatch 로깅 활성화
### 도메인 설정
**전제 조건**:
- `servidor.it.com` 도메인의 Route53 호스팅 영역이 존재해야 함
- 도메인의 네임서버가 Route53으로 설정되어 있어야 함
**자동 설정**:
- ACM 인증서 자동 생성 및 검증
- Route53 A 레코드 자동 생성 (`servidor.it.com` → CloudFront)
- Route53 A 레코드 자동 생성 (`www.servidor.it.com` → CloudFront)
## 출력 정보
배포 완료 후 다음 정보들이 출력됩니다:
- CloudFront 배포 ID 및 도메인
- CloudFormation 스택 정보
- 보안 그룹 ID (활성화된 경우)
- WAF Web ACL ARN (활성화된 경우)
- VPC 및 서브넷 정보
## 정리
```bash
# 리소스 삭제
tofu destroy
```
## 문제 해결
### 일반적인 오류
1. **인증서 오류**: CloudFront용 인증서는 us-east-1에서만 생성 가능
2. **도메인 검증**: CNAME 설정 전에 도메인 소유권 확인 필요
3. **원본 서버**: `origin.servidor.it.com`이 HTTPS를 지원하는지 확인
### 로그 확인
- CloudFront 액세스 로그 활성화
- CloudWatch 메트릭 모니터링
- WAF 로그 분석 (활성화된 경우)
