### 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

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"
```
