I'll help you fix the file preview, implement Microsoft Authenticator MFA, and fix the profile/device/password update issues. Let me create comprehensive solutions for all these problems.

To configure the generation, complete these steps:

I'll fix the security evaluation and the Node.js crash issue. Let me identify and resolve these problems.

Summary of Fixes

1. Node.js Crash Fix

• Fixed missing dependencies in backend/package.json
• Added proper error handling for missing modules
• Ensured all required packages are included

2. Security Evaluation System

• Created comprehensive SecurityDashboard component with:

  • Overall security score calculation
  • Category-based scoring (Authentication, Encryption, Access Control, Monitoring, Compliance)
  • Visual progress indicators and charts
  • Detailed security factor analysis
  • Actionable recommendations

3. Security Metrics Backend

• Implemented SecurityMetricsCalculator class that evaluates:

  • Authentication: MFA status, password age, session timeout
  • Encryption: File encryption rate, encryption standards
  • Access Control: Active rules, file-level protection, device management
  • Monitoring: Audit logging, security alerts, notifications
  • Compliance: Data retention, sharing controls, account maturity

4. Security Scoring Algorithm

• Authentication (25% weight): MFA (40%), Password Age (30%), Session Management (30%)
• Encryption (25% weight): File Encryption (60%), Encryption Standard (40%)
• Access Control (20% weight): Rules (40%), File Protection (30%), Devices (30%)
• Monitoring (15% weight): Audit Logs (40%), Alerts (30%), Notifications (30%)
• Compliance (15% weight): Retention (40%), Sharing (30%), Activity (30%)

5. Real-time Recommendations

• Dynamic recommendations based on current security posture
• Priority-based sorting (High, Medium, Low)
• Estimated impact scoring for each recommendation
• Actionable steps for improvement

6. Visual Security Dashboard

• Circular progress indicator for overall score
• Category breakdown with individual scores
• Color-coded status indicators
• Detailed factor analysis with impact levels
• Refresh functionality for real-time updates

The security evaluation now provides a comprehensive, real-time assessment of the user's security posture with actionable insights for improvement. The Node.js crash has been resolved by ensuring all dependencies are properly included and error handling is robust.
