Other Datastores
- Redis: Shared caching and session storage
- RabbitMQ: Message broker for inter-service communication
Database Version
- PostgreSQL: 17-alpine (latest stable - October 2024 release)
2. AUTHENTICATION & ACCESS CONTROL
✅ Strengths
Service Isolation
- Each service has its own dedicated database with unique credentials
- Prevents cross-service data access
- Limits blast radius of credential compromise
- Good security-by-design architecture
Password Authentication
- PostgreSQL uses scram-sha-256 authentication (modern, secure)
- Configured via
POSTGRES_INITDB_ARGS="--auth-host=scram-sha-256"in docker-compose.yml:412 - More secure than legacy MD5 authentication
- Resistant to password sniffing attacks
Redis Password Protection
requirepassenabled on Redis (docker-compose.yml:59)- Password-based authentication required for all connections
- Prevents unauthorized access to cached data
Network Isolation
- All databases run on internal Docker network (172.20.0.0/16)
- No direct external exposure
- ClusterIP services in Kubernetes (internal only)
- Cannot be accessed from outside the cluster
⚠️ Weaknesses
🔴 CRITICAL: Weak Default Passwords
- Current passwords:
auth_pass123,tenant_pass123,redis_pass123, etc. - Simple, predictable patterns
- Visible in secrets.yaml (base64 is NOT encryption)
- These are development passwords but may be in production
- Risk: Easy to guess if secrets file is exposed
No SSL/TLS for Database Connections
- PostgreSQL connections are unencrypted (no
sslmode=require) - Connection strings in shared/database/base.py:60 don't specify SSL parameters
- Traffic between services and databases is plaintext
- Impact: Network sniffing can expose credentials and data
Shared Redis Instance
- Single Redis instance used by all services
- No per-service Redis authentication
- Data from different services can theoretically be accessed cross-service
- Risk: Service compromise could leak data from other services
No Connection String Encryption in Transit
- Database URLs stored in Kubernetes secrets as base64 (not encrypted)
- Anyone with cluster access can decode credentials:
kubectl get secret bakery-ia-secrets -o jsonpath='{.data.AUTH_DB_PASSWORD}' | base64 -d
PgAdmin Configuration Shows "SSLMode": "prefer"
- infrastructure/pgadmin/servers.json shows SSL is preferred but not required
- Allows fallback to unencrypted connections
- Risk: Connections may silently downgrade to plaintext
3. DATA ENCRYPTION
🔴 Critical Findings
Encryption in Transit: NOT IMPLEMENTED
PostgreSQL
- ❌ No SSL/TLS configuration found in connection strings
- ❌ No
sslmode=requireorsslcertparameters - ❌ Connections use default PostgreSQL protocol (unencrypted port 5432)
- ❌ No certificate infrastructure detected
- Location: shared/database/base.py
Redis
- ❌ No TLS configuration
- ❌ Uses plain Redis protocol on port 6379
- ❌ All cached data transmitted in cleartext
- Location: docker-compose.yml:56, redis.yaml
RabbitMQ
- ❌ Uses port 5672 (AMQP unencrypted)
- ❌ No TLS/SSL configuration detected
- Location: rabbitmq.yaml
Impact
All database traffic within your cluster is unencrypted. This includes:
- User passwords (even though hashed, the connection itself is exposed)
- Personal data (GDPR-protected)
- Business-critical information (recipes, suppliers, sales)
- API keys and tokens stored in databases
- Session data in Redis
Encryption at Rest: NOT IMPLEMENTED
PostgreSQL
- ❌ No
pgcryptoextension usage detected - ❌ No Transparent Data Encryption (TDE)
- ❌ No filesystem-level encryption configured
- ❌ Volume mounts use standard
emptyDir(Kubernetes) or Docker volumes without encryption
Redis
- ❌ RDB/AOF persistence files are unencrypted
- ❌ Data stored in
/datawithout encryption - Location: redis.yaml:103
Storage Volumes
- Docker volumes in docker-compose.yml:17-39 are standard volumes
- Kubernetes uses
emptyDir: {}in auth-db.yaml:85 - No encryption specified at volume level
- Impact: Physical access to storage = full data access
⚠️ Partial Implementation
Application-Level Encryption
- ✅ POS service has encryption support for API credentials (pos/app/core/config.py:121)
- ✅
CREDENTIALS_ENCRYPTION_ENABLEDflag exists - ❌ But noted as "simplified" in code comments (pos_integration_service.py:53)
- ❌ Not implemented consistently across other services
Password Hashing
- ✅ User passwords are hashed with bcrypt via passlib (auth/app/core/security.py)
- ✅ Consistent implementation across services
- ✅ Industry-standard hashing algorithm
4. DATA PERSISTENCE & BACKUP
Current Configuration
Docker Compose (Development)
- ✅ Named volumes for all databases
- ✅ Data persists between container restarts
- ❌ Volumes stored on local filesystem without backup
- Location: docker-compose.yml:17-39
Kubernetes (Production)
- ⚠️ CRITICAL: Uses
emptyDir: {}for database volumes - 🔴 Data loss risk:
emptyDiris ephemeral - data deleted when pod dies - ❌ No PersistentVolumeClaims (PVCs) for PostgreSQL databases
- ✅ Redis has PersistentVolumeClaim (redis.yaml:103)
- Impact: Pod restart = complete database data loss for all PostgreSQL instances
Redis Persistence
- ✅ AOF (Append Only File) enabled (docker-compose.yml:58)
- ✅ Has PersistentVolumeClaim in Kubernetes
- ✅ Data written to disk for crash recovery
- Configuration:
appendonly yes
❌ Missing Components
No Automated Backups
- No
pg_dumpcron jobs - No backup CronJobs in Kubernetes
- No backup verification
- Risk: Cannot recover from data corruption, accidental deletion, or ransomware
No Backup Encryption
- Even if backups existed, no encryption strategy
- Backups could expose data if storage is compromised
No Point-in-Time Recovery
- PostgreSQL WAL archiving not configured
- Cannot restore to specific timestamp
- Impact: Can only restore to last backup (if backups existed)
No Off-Site Backup Storage
- No S3, GCS, or external backup target
- Single point of failure
- Risk: Disaster recovery impossible

7. RECOMMENDATIONS
🔥 IMMEDIATE (Do This Week)
1. Fix Kubernetes Volume Configuration
Priority: CRITICAL - Prevents data loss
# Replace emptyDir with PVC in all *-db.yaml files
volumes:
- name: postgres-data
persistentVolumeClaim:
claimName: auth-db-pvc # Create PVC for each DB
Action: Create PVCs for all 14 PostgreSQL databases
2. Change All Default Passwords
Priority: CRITICAL
- Generate strong, random passwords (32+ characters)
- Use a password manager or secrets management tool
- Update all secrets in Kubernetes and
.envfiles - Never use passwords like
*_pass123in any environment
Script:
# Generate strong password
openssl rand -base64 32
3. Update Privacy Policy
Priority: HIGH - Legal compliance
- Remove claims about encryption until it's actually implemented, or
- Implement encryption immediately (see below)
Legal risk: Misrepresentation can lead to regulatory action
⏱️ SHORT-TERM (This Month)
4. Implement TLS for PostgreSQL Connections
Step 1: Generate SSL certificates
# Generate self-signed certs for internal use
openssl req -new -x509 -days 365 -nodes -text \
-out server.crt -keyout server.key \
-subj "/CN=*.bakery-ia.svc.cluster.local"
Step 2: Configure PostgreSQL to require SSL
# Add to postgres container env
- name: POSTGRES_SSL_MODE
value: "require"
Step 3: Update connection strings
# In service configs
DATABASE_URL = f"postgresql+asyncpg://{user}:{password}@{host}:{port}/{name}?ssl=require"
Estimated effort: 1.5 hours
5. Implement Automated Backups
Create Kubernetes CronJob for pg_dump:
apiVersion: batch/v1
kind: CronJob
metadata:
name: postgres-backup
spec:
schedule: "0 2 * * *" # Daily at 2 AM
jobTemplate:
spec:
template:
spec:
containers:
- name: backup
image: postgres:17-alpine
command:
- /bin/sh
- -c
- |
pg_dump $DATABASE_URL | \
gzip | \
gpg --encrypt --recipient backup@bakery-ia.com > \
/backups/backup-$(date +%Y%m%d).sql.gz.gpg
Store backups in S3/GCS with encryption enabled.
Retention policy:
- Daily backups: 30 days
- Weekly backups: 90 days
- Monthly backups: 1 year
6. Enable Redis TLS
Update Redis configuration:
command:
- redis-server
- --tls-port 6379
- --port 0 # Disable non-TLS port
- --tls-cert-file /tls/redis.crt
- --tls-key-file /tls/redis.key
- --tls-ca-cert-file /tls/ca.crt
- --requirepass $(REDIS_PASSWORD)
Estimated effort: 1 hour
7. Implement Kubernetes Secrets Encryption
Enable encryption at rest for Kubernetes secrets:
# Create EncryptionConfiguration
apiVersion: apiserver.config.k8s.io/v1
kind: EncryptionConfiguration
resources:
- resources:
- secrets
providers:
- aescbc:
keys:
- name: key1
secret: <base64-encoded-32-byte-key>
- identity: {} # Fallback to unencrypted
Apply to Kind cluster via extraMounts in kind-config.yaml
Estimated effort: 45 minutes
📅 MEDIUM-TERM (Next Quarter)
8. Implement Encryption at Rest
Option A: PostgreSQL pgcrypto Extension (Column-level)
CREATE EXTENSION pgcrypto;
-- Encrypt sensitive columns
CREATE TABLE users (
id UUID PRIMARY KEY,
email TEXT,
encrypted_ssn BYTEA -- Store encrypted data
);
-- Insert encrypted data
INSERT INTO users (id, email, encrypted_ssn)
VALUES (
gen_random_uuid(),
'user@example.com',
pgp_sym_encrypt('123-45-6789', 'encryption-key')
);
Option B: Filesystem Encryption (Better)
- Use encrypted storage classes in Kubernetes
- LUKS encryption for volumes
- Cloud provider encryption (AWS EBS encryption, GCP persistent disk encryption)
Recommendation: Option B (transparent, no application changes)
9. Separate Redis Instances per Service
- Deploy dedicated Redis instances for sensitive services (auth, tenant)
- Use Redis Cluster for scalability
- Implement Redis ACLs (Access Control Lists) in Redis 6+
Benefits:
- Better isolation
- Limit blast radius of compromise
- Independent scaling
10. Implement Database Audit Logging
Enable PostgreSQL audit extension:
-- Install pgaudit extension
CREATE EXTENSION pgaudit;
-- Configure logging
ALTER SYSTEM SET pgaudit.log = 'all';
ALTER SYSTEM SET pgaudit.log_relation = on;
ALTER SYSTEM SET pgaudit.log_catalog = off;
ALTER SYSTEM SET pgaudit.log_parameter = on;
Ship logs to centralized logging (ELK, Grafana Loki)
Log retention: 90 days minimum (GDPR compliance)
11. Implement Connection Pooling with PgBouncer
Deploy PgBouncer between services and databases:
apiVersion: apps/v1
kind: Deployment
metadata:
name: pgbouncer
spec:
template:
spec:
containers:
- name: pgbouncer
image: pgbouncer/pgbouncer:latest
env:
- name: MAX_CLIENT_CONN
value: "1000"
- name: DEFAULT_POOL_SIZE
value: "25"
Benefits:
- Prevents connection exhaustion
- Improves performance
- Adds connection-level security
- Reduces database load
🎯 LONG-TERM (Next 6 Months)
