+
+### 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](config/docker-compose.yml#L412)
+- More secure than legacy MD5 authentication
+- Resistant to password sniffing attacks
+
+#### Redis Password Protection
+- `requirepass` enabled on Redis ([docker-compose.yml:59](config/docker-compose.yml#L59))
+- 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](infrastructure/kubernetes/base/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](shared/database/base.py#L60) 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:
+  ```bash
+  kubectl get secret bakery-ia-secrets -o jsonpath='{.data.AUTH_DB_PASSWORD}' | base64 -d
+  ```
+
+#### PgAdmin Configuration Shows "SSLMode": "prefer"
+- [infrastructure/pgadmin/servers.json](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=require` or `sslcert` parameters
+- ❌ Connections use default PostgreSQL protocol (unencrypted port 5432)
+- ❌ No certificate infrastructure detected
+- **Location:** [shared/database/base.py](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](config/docker-compose.yml#L56), [redis.yaml](infrastructure/kubernetes/base/components/databases/redis.yaml)
+
+#### RabbitMQ
+- ❌ Uses port 5672 (AMQP unencrypted)
+- ❌ No TLS/SSL configuration detected
+- **Location:** [rabbitmq.yaml](infrastructure/kubernetes/base/components/databases/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 `pgcrypto` extension 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 `/data` without encryption
+- **Location:** [redis.yaml:103](infrastructure/kubernetes/base/components/databases/redis.yaml#L103)
+
+#### Storage Volumes
+- Docker volumes in [docker-compose.yml:17-39](config/docker-compose.yml#L17-L39) are standard volumes
+- Kubernetes uses `emptyDir: {}` in [auth-db.yaml:85](infrastructure/kubernetes/base/components/databases/auth-db.yaml#L85)
+- 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](services/pos/app/core/config.py#L121))
+- ✅ `CREDENTIALS_ENCRYPTION_ENABLED` flag exists
+- ❌ But noted as "simplified" in code comments ([pos_integration_service.py:53](services/pos/app/services/pos_integration_service.py#L53))
+- ❌ Not implemented consistently across other services
+
+#### Password Hashing
+- ✅ User passwords are hashed with **bcrypt** via passlib ([auth/app/core/security.py](services/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](config/docker-compose.yml#L17-L39)
+
+#### Kubernetes (Production)
+- ⚠️ **CRITICAL:** Uses `emptyDir: {}` for database volumes
+- 🔴 **Data loss risk:** `emptyDir` is ephemeral - data deleted when pod dies
+- ❌ No PersistentVolumeClaims (PVCs) for PostgreSQL databases
+- ✅ Redis has PersistentVolumeClaim ([redis.yaml:103](infrastructure/kubernetes/base/components/databases/redis.yaml#L103))
+- **Impact:** Pod restart = complete database data loss for all PostgreSQL instances
+
+#### Redis Persistence
+- ✅ AOF (Append Only File) enabled ([docker-compose.yml:58](config/docker-compose.yml#L58))
+- ✅ Has PersistentVolumeClaim in Kubernetes
+- ✅ Data written to disk for crash recovery
+- **Configuration:** `appendonly yes`
+
+### ❌ Missing Components
+
+#### No Automated Backups
+- No `pg_dump` cron 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
+
+```yaml
+# 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 `.env` files
+- Never use passwords like `*_pass123` in any environment
+
+**Script:**
+```bash
+# 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
+```bash
+# 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
+```yaml
+# Add to postgres container env
+- name: POSTGRES_SSL_MODE
+  value: "require"
+```
+
+**Step 3:** Update connection strings
+```python
+# 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`:
+
+```yaml
+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:
+
+```yaml
+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:
+
+```yaml
+# 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)
+
+```sql
+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:
+
+```sql
+-- 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:
+
+```yaml
+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)
+
+#### 12. Migrate to Managed Database Services
+
+Consider cloud-managed databases:
+
+| Provider | Service | Key Features |
+|----------|---------|--------------|
+| AWS | RDS PostgreSQL | Built-in encryption, automated backups, SSL by default |
+| Google Cloud | Cloud SQL | Automatic encryption, point-in-time recovery |
+| Azure | Database for PostgreSQL | Encryption at rest/transit, geo-replication |
+
+**Benefits:**
+- ✅ Encryption at rest (automatic)
+- ✅ Encryption in transit (enforced)
+- ✅ Automated backups
+- ✅ Point-in-time recovery
+- ✅ High availability
+- ✅ Compliance certifications (SOC 2, ISO 27001, GDPR)
+- ✅ Reduced operational burden
+
+**Estimated cost:** $200-500/month for 14 databases (depending on size)
+
+#### 13. Implement HashiCorp Vault for Secrets Management
+
+Replace Kubernetes secrets with Vault:
+
+- Dynamic database credentials (auto-rotation)
+- Automatic rotation (every 24 hours)
+- Audit logging for all secret access
+- Encryption as a service
+- Centralized secrets management
+
+**Integration:**
+```yaml
+# Service account with Vault
+annotations:
+  vault.hashicorp.com/agent-inject: "true"
+  vault.hashicorp.com/role: "auth-service"
+  vault.hashicorp.com/agent-inject-secret-db: "database/creds/auth-db"
+```
+
+#### 14. Implement Database Activity Monitoring (DAM)
+
+Deploy a DAM solution:
+- Real-time monitoring of database queries
+- Anomaly detection (unusual queries, data exfiltration)
+- Compliance reporting (GDPR data access logs)
+- Blocking of suspicious queries
+- Integration with SIEM
+
+**Options:**
+- IBM Guardium
+- Imperva SecureSphere
+- DataSunrise
+- Open source: pgAudit + ELK stack
+
+#### 15. Setup Multi-Region Disaster Recovery
+
+- Configure PostgreSQL streaming replication
+- Setup cross-region backups
+- Test disaster recovery procedures quarterly
+- Document RPO/RTO targets
+
+**Targets:**
+- RPO (Recovery Point Objective): 15 minutes
+- RTO (Recovery Time Objective): 1 hour
