Security Documentation

Security Overview

The DeFi Oracle Meta Mainnet implements multiple layers of security to protect the network and its users.

Key Management

Validator Keys

• Stored in Azure Key Vault
• Never stored on disk
• Rotated every 90 days
• Access restricted to validators only

Oracle Keys

• Stored in Azure Key Vault
• Used via EthSigner
• Rotated every 90 days
• Access restricted to oracle publisher service

Key Rotation

1. Generate new keys
2. Update Key Vault
3. Update node configurations
4. Restart nodes
5. Verify new keys are working
6. Remove old keys after verification

Network Security

Network Segmentation

• Validators: Private subnets, no public IPs
• Sentries: Public subnets, P2P access only
• RPC Nodes: DMZ subnet, HTTPS only

Firewall Rules

• Validators: Internal communication only
• Sentries: P2P (30303) and internal communication
• RPC Nodes: HTTPS (443) and internal communication

TLS/SSL

• TLS 1.2+ for all HTTPS connections
• mTLS for internal communication
• Certificate rotation every 90 days

Access Control

Node Permissioning

• Static node allowlists
• Prevents unauthorized nodes from joining
• Updated via configuration files

Account Permissioning

• Account allowlists for RPC methods
• Prevents unauthorized transactions
• Updated via configuration files

API Gateway

• Rate limiting per IP
• API key authentication (optional)
• Method allowlists
• CORS configuration

Security Monitoring

Logging

• All node operations logged
• Structured logging (JSON)
• Log aggregation (Loki)
• Log retention (30 days)

Monitoring

• Prometheus metrics
• Alert rules for security events
• Grafana dashboards
• Alertmanager notifications

Incident Response

• Security incident playbook
• Incident response team
• Escalation procedures
• Post-incident reviews

Vulnerability Management

Regular Audits

• Code audits quarterly
• Security audits annually
• Penetration testing annually
• Dependency updates monthly

Patch Management

• Security patches applied within 24 hours
• Regular updates for dependencies
• Node software updates quarterly
• Emergency patches as needed

Compliance

Data Protection

• No personal data stored on-chain
• Privacy by design
• Data retention policies
• GDPR compliance (if applicable)

Access Logging

• All RPC requests logged
• Access logs retained for 90 days
• Audit trails for admin operations
• Compliance reporting

Security Best Practices

For Operators

1. Use strong passwords
2. Enable multi-factor authentication
3. Rotate keys regularly
4. Monitor security alerts
5. Keep software updated

For Developers

1. Follow secure coding practices
2. Use dependency scanning
3. Perform code reviews
4. Test security controls
5. Document security assumptions

For Users

1. Verify contract addresses
2. Use trusted RPC endpoints
3. Check transaction details
4. Monitor account activity
5. Report suspicious activity

Security Incidents

Reporting

• Report security issues to security@d-bis.org
• Include detailed information
• Do not disclose publicly until fixed

Response

1. Acknowledge receipt
2. Assess severity
3. Develop mitigation
4. Deploy fix
5. Notify users
6. Post-incident review
