-# Dataverse's Security Policies and Procedures <!-- omit in toc -->
+# Security Implementation Documentation
 
-This document outlines security procedures and general policies for the
-Dataverse project.
+## Overview
 
-- [Reporting a Vulnerability](#reporting-a-vulnerability)
-- [Disclosure Policy](#disclosure-policy)
+This document outlines the security enhancements implemented in Dataverse to protect user data and prevent common security vulnerabilities.
 
-## Reporting a Vulnerability 
+## Security Features Implemented
 
-The Dataverse team and community takes all security vulnerabilities
-seriously. Thank you for improving the security of our open source 
-software. We appreciate your efforts and responsible disclosure and will
-make every effort to acknowledge your contributions.
+### 🔐 Password Security
 
-Report security vulnerabilities by emailing the Dataverse team at:
+- **Secure Hashing**: Replaced custom encryption with bcrypt hashing
+- **Salt Generation**: Each password gets a unique salt
+- **Password Strength**: Enforced strong password requirements
+- **Migration Support**: Existing passwords are migrated securely
 
+### 🌍 Environment Configuration
+
+- **Environment Variables**: Database credentials moved to `.env` file
+- **Configuration Management**: Centralized configuration with defaults
+- **Secret Management**: Secure handling of sensitive configuration
+
+### 🛡️ SQL Injection Prevention
+
+- **Parameterized Queries**: All database queries use parameter binding
+- **Input Validation**: Comprehensive validation for all user inputs
+- **Data Sanitization**: Automatic sanitization of user data
+
+### 🎫 Session Management
+
+- **Token-Based Sessions**: Secure session tokens using cryptographic random generation
+- **Session Timeout**: Automatic session expiration
+- **Session Validation**: Proper session validation and cleanup
+
+### 🚫 Account Protection
+
+- **Failed Attempt Tracking**: Monitor and limit failed login attempts
+- **Account Lockout**: Temporary account lockout after multiple failures
+- **Brute Force Protection**: Protection against brute force attacks
+
+## Security Configuration
+
+### Environment Variables
+
+Create a `.env` file with the following variables:
+
+```env
+# Database Configuration
+DB_HOST=localhost
+DB_USER=your_username
+DB_PASSWORD=your_secure_password
+DB_NAME=DATAVERSE
+
+# Security Configuration
+SECRET_KEY=your_secret_key_here
+SESSION_TIMEOUT=3600
+
+# Application Configuration
+APP_DEBUG=False
 ```
-multiverse.letter@gmail.com
+
+### Password Requirements
+
+- Minimum 8 characters
+- At least one uppercase letter
+- At least one lowercase letter
+- At least one digit
+- At least one special character
+- Protection against common weak passwords
+
+### Session Configuration
+
+- Default timeout: 1 hour (3600 seconds)
+- Automatic cleanup of expired sessions
+- Secure token generation using `secrets` module
+
+## Migration Process
+
+### Before Migration
+
+1. **Backup Database**: The migration script automatically creates a backup
+2. **Install Dependencies**: Ensure `bcrypt` and `python-dotenv` are installed
+3. **Configure Environment**: Set up your `.env` file
+
+### Running Migration
+
+```bash
+python migration_script.py
 ```
 
-The lead maintainer will acknowledge your email within 24 hours and will
-send a more detailed response within 48 hours indicating the next steps in 
-handling your report. After the initial reply to your report, the security
-team will endeavor to keep you informed of the progress towards a fix and
-full announcement, and may ask for additional information or guidance.
+### After Migration
+
+1. **Test Login**: Verify existing users can still log in
+2. **Test Registration**: Create new users to test the system
+3. **Remove Backup**: Once satisfied, remove the backup table
+
+## Security Best Practices
+
+### For Developers
+
+1. **Never Hardcode Credentials**: Always use environment variables
+2. **Use Parameterized Queries**: Never use string formatting for SQL
+3. **Validate All Inputs**: Validate and sanitize all user inputs
+4. **Handle Errors Securely**: Don't expose sensitive information in errors
+
+### For Deployment
+
+1. **Secure Environment File**: Protect the `.env` file with proper permissions
+2. **Use Strong Secrets**: Generate strong, unique secret keys
+3. **Regular Updates**: Keep dependencies updated for security patches
+4. **Monitor Logs**: Monitor for suspicious activities
+
+## Security Testing
+
+### Manual Testing
+
+1. **SQL Injection**: Test with malicious SQL in input fields
+2. **Password Strength**: Test weak password rejection
+3. **Session Management**: Test session timeout and validation
+4. **Account Lockout**: Test failed login attempt limits
+
+### Automated Testing
+
+Consider implementing:
+- Unit tests for validation functions
+- Integration tests for authentication
+- Security scanning tools
+- Dependency vulnerability scanning
+
+## Incident Response
+
+### If Security Issue Detected
+
+1. **Immediate Action**: Change all secrets and passwords
+2. **Assess Impact**: Determine what data may have been compromised
+3. **Update System**: Apply security patches immediately
+4. **Monitor**: Increase monitoring for suspicious activities
+
+### Reporting Security Issues
+
+If you discover a security vulnerability:
+1. **Do Not** create a public issue
+2. Contact the maintainers privately
+3. Provide detailed information about the vulnerability
+4. Allow time for the issue to be fixed before disclosure
+
+## Compliance Notes
+
+This implementation follows security best practices including:
+- OWASP Top 10 protection guidelines
+- Password hashing standards (bcrypt)
+- Session management best practices
+- Input validation and sanitization standards
+
+## Dependencies
+
+### Security-Related Dependencies
+
+- `bcrypt>=4.0.1`: Secure password hashing
+- `python-dotenv>=1.0.0`: Environment variable management
+
+### Security Considerations
+
+- Keep dependencies updated
+- Monitor for security advisories
+- Use dependency scanning tools
+
+## Changelog
+
+### Version 1.0 (Security Enhancement)
+
+- ✅ Implemented bcrypt password hashing
+- ✅ Added environment variable configuration
+- ✅ Implemented parameterized queries
+- ✅ Added comprehensive input validation
+- ✅ Implemented secure session management
+- ✅ Added account lockout protection
+- ✅ Created migration script for existing data
+
+## Future Enhancements
+
+### Planned Security Improvements
+

+- [ ] Unusual activity detection
+- [ ] Security event logging
+- [ ] Automated security scanning
 
-When the security team receives a security bug report, they will assign it
-to a primary handler. This person will coordinate the fix and release
-process, involving the following steps:
+---
 
-  * Confirm the problem.
-  * Audit code to find any potential similar problems.
-  * Prepare fixes and release them as fast as possible.
+For questions about security implementation, please refer to the implementation guide or contact the development team.
