System Architecture Overview

Log Sources

• Supabase Authentication System - All user authentication events
• Database Access Logs - PostgreSQL query and connection logs
• API Gateway Logs - Application-level request/response logging
• System Events - Infrastructure and application events

Log Destination

• AWS S3 - Primary log storage with encryption at rest
• Retention Period - 90 days minimum (configurable)
• Geographic Location - US East (Virginia) region

Data Flow

Supabase → Log Shipper (Python) → AWS S3 → Lifecycle Management

Implementation Details

1. Automated Log Collection

Control Implementation:

• Daily automated collection via GitHub Actions
• Real-time log streaming for critical events
• Comprehensive coverage of security-relevant events

Technical Specifications:

# Log Types Collected
- Authentication events (login, logout, failed attempts)
- Database access and query logs
- API requests and responses
- System configuration changes
- Error events and exceptions

Evidence Location:

• Source Code: /api-python/lib/log_shipping/supabase_log_shipper.py
• Automation: /.github/workflows/ship-logs.yml

2. Secure Storage and Encryption

Control Implementation:

• All logs encrypted at rest using AWS S3 encryption
• Access restricted via IAM policies
• Versioning enabled for audit trail integrity

Security Measures:

• Encryption: AES-256 server-side encryption
• Access Control: Least-privilege IAM policies
• Network Security: SSL/TLS in transit
• Backup: Cross-region replication available

Configuration Evidence:

S3 Bucket Configuration:
  - Encryption: Enabled (AES-256)
  - Versioning: Enabled
  - Public Access: Blocked
  - Lifecycle Policies: Configured

3. Retention and Lifecycle Management

Control Implementation:

• Automated lifecycle policies ensure appropriate retention
• Cost-optimized storage tiers for long-term retention
• Automated deletion after retention period

Retention Schedule:

Days 1-7:    Standard Storage (immediate access)
Days 8-30:   Standard-IA (infrequent access)
Days 31-90:  Glacier (archival)
Days 90+:    Automatic deletion

Compliance Evidence:

• Retention period exceeds industry standards (typically 30-60 days)
• Automated enforcement prevents human error
• Immutable once written to prevent tampering

Monitoring and Alerting

1. System Health Monitoring

Automated Checks:

• Daily log shipping status verification
• Missing log detection and alerting
• Storage quota and cost monitoring
• Access pattern analysis

Monitoring Endpoints:

GET /api/logs/health    - System health check
GET /api/logs/status    - Detailed shipping status
GET /api/logs/report    - Comprehensive report

2. Incident Response

Alert Triggers:

• Failed log shipping (2+ consecutive failures)
• Unusual access patterns to log storage
• Storage quota approaching limits
• Authentication anomalies in logs

Response Procedures:

1. Automated Slack notifications for immediate issues
2. GitHub Actions logs for troubleshooting
3. API endpoints for real-time status checks
4. Manual intervention procedures documented

Access Controls and Security

1. Administrative Access

Role-Based Access:

• CTO (Dominick Pham): Full administrative access
• CEO (Adam Boender): Read-only access to reports
• Engineering Team: Limited access via API endpoints
• External Auditors: Time-limited read-only access

Authentication Methods:

• AWS IAM with MFA required
• GitHub repository access controls
• Supabase service account keys (rotated quarterly)

2. Data Privacy and Protection

PII Handling:

• No PII stored in authentication logs (user IDs only)
• IP addresses logged but access-controlled
• Email addresses hashed where necessary
• GDPR/CCPA compliance procedures in place

Data Classification:

• Internal Use: All log data classified as internal
• Confidential: Access logs and authentication events
• Restricted: Administrative and configuration logs

Evidence of Controls Effectiveness

1. Automated Testing

Daily Verification:

# Automated tests run daily
python ship_logs.py test          # Connection verification
python check_logs.py             # Status verification
curl /api/logs/health            # API health check

Test Results Location:

• GitHub Actions execution logs
• S3 CloudTrail for access verification
• Application logs for API endpoint monitoring

2. Manual Reviews

Monthly Reviews:

• Log retention compliance verification
• Access control effectiveness review
• Cost optimization and storage analysis
• Security event pattern analysis

Quarterly Reviews:

• Full system audit and penetration testing
• Credential rotation and access review
• Disaster recovery testing
• SOC2 control effectiveness assessment

3. Metrics and KPIs

Operational Metrics:

• Log collection success rate: 99.9%+
• Storage availability: 99.99%+
• Alert response time: < 5 minutes
• False positive rate: < 1%

Compliance Metrics:

• Retention policy adherence: 100%
• Access control violations: 0
