M6-1: Security Scanning Tool

Epic: Milestone 6 - Security & Production Readiness
Story Points: 8
Priority: High
Assignee: Development Team
Labels: security, production, milestone-6

Objective

Implement comprehensive security scanning tool to identify vulnerabilities in the Unraid system, Docker containers, and application configurations. This tool provides essential security insights for production deployments.

User Story

As a system administrator, I want to scan my Unraid system for security vulnerabilities so that I can identify and remediate potential security risks before they impact my infrastructure.

Detailed Requirements

Functional Requirements

Container Vulnerability Scanning
- Scan Docker images for known CVEs
- Identify outdated base images and packages
- Report security patches and updates available
- Integration with container registries for security metadata
System Security Assessment
- Check for common Unraid security misconfigurations
- Validate user permissions and access controls
- Scan for exposed services and open ports
- Assess password policies and authentication settings
Configuration Security Analysis
- Analyze AppData configurations for security issues
- Check for hardcoded credentials and secrets
- Validate SSL/TLS certificate configurations
- Review Docker compose security settings
Compliance and Reporting
- Generate security compliance reports
- Track security metrics and trends over time
- Export findings in multiple formats (JSON, CSV, PDF)
- Integration with security monitoring tools

Implementation Requirements

Effect.ts Implementation Pattern

export const performSecurityScan = (
  request: SecurityScanRequest
): Effect.Effect<SecurityScanResponse, SecurityScanError, SecurityService> =>
  Effect.gen(function* () {
    const securityService = yield* SecurityService;
    
    // Validate scan scope and parameters
    const validatedRequest = yield* validateScanRequest(request);
    
    // Initialize security scanning context
    const scanContext = yield* initializeScanContext(validatedRequest);
    
    // Perform security analysis based on scope
    const scanResults = yield* performScanAnalysis(scanContext);
    
    // Generate compliance assessment
    const complianceResults = yield* assessCompliance(scanResults);
    
    // Format response with security recommendations
    return formatSecurityScanResponse(scanResults, complianceResults);
  }).pipe(
    Effect.timeout("180 seconds"),
    Effect.retry(Schedule.exponential("1 second", 2.0).pipe(Schedule.recurs(2))),
    Effect.withSpan("security-scan-operation")
  );

Security Service Integration

interface SecurityService {
  readonly scanContainerVulnerabilities: (
    containers: ReadonlyArray<ContainerInfo>
  ) => Effect.Effect<ContainerVulnerabilityReport, SecurityScanError>;
  
  readonly scanSystemConfiguration: () => Effect.Effect<SystemSecurityReport, SecurityScanError>;
  
  readonly scanAppDataConfigurations: (
    appDataPaths: ReadonlyArray<string>
  ) => Effect.Effect<ConfigurationSecurityReport, SecurityScanError>;
  
  readonly generateComplianceReport: (
    findings: ReadonlyArray<SecurityFinding>
  ) => Effect.Effect<ComplianceReport, SecurityScanError>;
}
