Data Exposure and Privacy + +- [x] **Sensitive Data Logging**: Verified that SQL parameters are logged but PII data is not exposed in plain text +- [x] **SQL Injection Prevention**: Confirmed parameterized queries are used throughout, no string concatenation +- [x] **Error Message Sanitization**: Error messages don't expose internal system details to external users +- [x] **Diagnostic Data Scope**: Diagnostic information includes only operational metrics, not user data +- [x] **Log Level Appropriateness**: Debug logs contain operational details, info logs contain high-level status + +### 2. Authentication and Authorization + +- [x] **Access Control**: Diagnostic methods are internal to the application, not exposed via external APIs +- [x] **Method Visibility**: All diagnostic methods are properly scoped and not publicly accessible +- [x] **Component Security**: Test component is development-only and should not be included in production builds +- [x] **Service Layer Protection**: Database service maintains singleton pattern preventing unauthorized instantiation + +### 3. Input Validation and Sanitization + +- [x] **Parameter Validation**: SQL parameters are validated through existing platform service layer +- [x] **Query Sanitization**: All queries use parameterized statements, preventing SQL injection +- [x] **Log Message Sanitization**: Log messages are properly escaped and truncated to prevent log injection +- [x] **Diagnostic Output Sanitization**: Diagnostic output is structured JSON, preventing injection attacks + +### 4. Resource Management and DoS Prevention + +- [x] **Queue Size Monitoring**: Warning logs when operation queue exceeds 50 items +- [x] **Memory Management**: Diagnostic data is bounded and doesn't accumulate indefinitely +- [x] **Performance Impact**: Logging operations are asynchronous and non-blocking +- [x] **Log Rotation**: Relies on external log management system for rotation and cleanup +- [x] **Resource Cleanup**: Proper cleanup of diagnostic resources and temporary data + +### 5. Information Disclosure + +- [x] **Stack Trace Handling**: Full stack traces only logged at debug level, not exposed to users +- [x] **System Information**: Minimal system information logged (platform, browser type only) +- [x] **Database Schema Protection**: No database schema information exposed in logs +- [x] **Operational Metrics**: Only performance metrics exposed, not sensitive operational data + +### 6. Error Handling and Recovery + +- [x] **Graceful Degradation**: Diagnostic features fail gracefully without affecting core functionality +- [x] **Error Isolation**: Logging failures don't cascade to database operations +- [x] **Recovery Mechanisms**: Initialization failures are properly handled with retry logic +- [x] **State Consistency**: Database state remains consistent even if logging fails + +### 7. Cross-Platform Security + +- [x] **Web Platform**: Browser-based logging doesn't expose server-side information +- [x] **Mobile Platform**: Capacitor implementation properly sandboxes diagnostic data +- [x] **Platform Isolation**: Platform-specific diagnostic data is properly isolated +- [x] **Interface Consistency**: All platforms implement the same security model + +### 8. Compliance and Audit Trail + +- [x] **Audit Logging**: Comprehensive audit trail for database operations and health checks +- [x] **Timestamp Accuracy**: All logs include accurate ISO timestamps +- [x] **Data Retention**: Logs are managed by external system for compliance requirements +- [x] **Traceability**: Operation IDs enable tracing of database operations + +## Security Recommendations + +### High Priority +1. **Production Builds**: Ensure `DiagnosticsTestComponent` is excluded from production builds +2. **Log Level Configuration**: Implement runtime log level configuration for production +3. **Rate Limiting**: Consider implementing rate limiting for diagnostic operations + +### Medium Priority +1. **Log Encryption**: Consider encrypting sensitive diagnostic data at rest +2. **Access Logging**: Add logging for diagnostic method access patterns +3. **Automated Monitoring**: Implement automated alerting for diagnostic anomalies + +### Low Priority +1. **Log Aggregation**: Implement centralized log aggregation for better analysis +2. **Metrics Dashboard**: Create operational dashboard for diagnostic metrics +3. **Performance Profiling**: Add performance profiling for diagnostic operations + +## Compliance Notes + +- **GDPR**: No personal data is logged in diagnostic information +- **HIPAA**: Medical data is not exposed through diagnostic channels +- **SOC 2**: Audit trails are maintained for all database operations +- **ISO 27001**: Information security controls are implemented for logging + +## Testing and Validation + +### Security Tests Required +- [ ] Penetration testing of diagnostic endpoints +- [ ] Log injection attack testing +- [ ] Resource exhaustion testing +- [ ] Cross-site scripting (XSS) testing of diagnostic output +- [ ] Authentication bypass testing + +### Monitoring and Alerting +- [ ] Set up alerts for unusual diagnostic patterns +- [ ] Monitor for potential information disclosure +- [ ] Track diagnostic performance impact +- [ ] Monitor queue growth patterns + +## Sign-off + +**Security Review Completed:** July 1, 2025 +**Reviewer:** Matthew Raymer +**Status:** โœ… Approved with recommendations +**Next Review:** October 1, 2025 \ No newline at end of file diff --git a/docs/compact-database-comparison.md b/docs/compact-database-comparison.md new file mode 100644 index 00000000..d69e7871 --- /dev/null +++ b/docs/compact-database-comparison.md @@ -0,0 +1,209 @@ +# Compact Database API - Before vs After Comparison + +## The Problem: Verbose Database Operations + +The current database operations require significant boilerplate code, making simple operations unnecessarily complex. + +## Before: Verbose & Repetitive โŒ + +### Loading Data +```typescript +// 6 lines for a simple query! +@Component +export default class ContactsView extends Vue { + async loadContacts() { + const platformService = PlatformServiceFactory.getInstance(); + const result = await platformService.dbQuery("SELECT * FROM contacts WHERE visible = ?", [1]); + const contacts = databaseUtil.mapQueryResultToValues(result) as Contact[]; + await databaseUtil.logToDb(`Loaded ${contacts.length} contacts`); + this.contacts = contacts; + } +} +``` + +### Saving Data +```typescript +// 8+ lines for a simple insert! +async saveContact(contact: Contact) { + const platformService = PlatformServiceFactory.getInstance(); + const { sql, params } = databaseUtil.generateInsertStatement(contact, "contacts"); + const result = await platformService.dbExec(sql, params); + await databaseUtil.logToDb(`Contact saved with ID: ${result.lastId}`); + if (result.changes !== 1) { + throw new Error("Failed to save contact"); + } + return result; +} +``` + +### Settings Management +```typescript +// 4+ lines for settings +async updateAppSettings(newSettings: Partial) { + const success = await databaseUtil.updateDefaultSettings(newSettings as Settings); + await databaseUtil.logToDb(success ?
