This project is actively maintained. Security updates are provided for the following versions:

We take the security of this project seriously. If you discover a security vulnerability, please follow these steps:

1. DO NOT create a public GitHub issue for security vulnerabilities
2. Email security concerns to: [your-email@example.com]
3. Include the following information:
   • Description of the vulnerability
   • Steps to reproduce the issue
   • Potential impact
   • Suggested fix (if any)

• Acknowledgment: We will acknowledge receipt of your vulnerability report within 48 hours
• Assessment: We will assess the vulnerability and determine its severity within 5 business days
• Updates: We will keep you informed of our progress
• Resolution: We aim to resolve critical vulnerabilities within 30 days
• Credit: We will credit you in the security advisory (unless you prefer to remain anonymous)

1. Never commit sensitive data:

   • API keys
   • Passwords
   • Connection strings
   • Certificates
   • Private keys

2. Use environment variables or secure configuration:

   • Store secrets in Azure Key Vault
   • Use environment-specific configuration files
   • Never commit appsettings.json with real credentials

3. Keep dependencies updated:

   • Regularly update NuGet packages
   • Monitor Dependabot alerts
   • Review security advisories

4. Follow secure coding practices:

   • Validate all user input
   • Use parameterized queries
   • Implement proper authentication and authorization
   • Enable HTTPS/TLS

This repository includes:

• ✅ appsettings.example.json - Template with placeholders
• ❌ appsettings.json - Excluded from repository (contains real secrets)

Always use the example file as a template and create your own configuration files locally.

• JWT tokens are used for API authentication
• Tokens should be stored securely on the client side
• Token expiration should be configured appropriately

• All third-party API keys must be stored in configuration
• Never hardcode API keys in source code
• Rotate API keys regularly

• Use parameterized queries to prevent SQL injection
• Implement proper access controls
• Encrypt sensitive data at rest

• Always use HTTPS in production
• Configure proper SSL/TLS certificates
• Enforce HTTPS redirection

This project implements:

• ✅ JWT Authentication - Token-based authentication
• ✅ Input Validation - Request validation and sanitization
• ✅ SQL Injection Prevention - Parameterized queries
• ✅ CORS Configuration - Cross-origin resource sharing controls
• ✅ Rate Limiting - API throttling
• ✅ HTTPS Enforcement - Secure communication
• ✅ Certificate-based Auth - For secure supplier integrations

We use:

• Dependabot - Automated dependency updates
• GitHub Security Advisories - Vulnerability notifications
• NuGet Package Vulnerability Scanning - Built-in .NET security

• Regular security audits of dependencies
• Review of third-party package licenses
• Assessment of package maintainer reputation

This project follows:

• OWASP Top 10 - Web application security risks
• CWE/SANS Top 25 - Most dangerous software weaknesses
• Microsoft Security Development Lifecycle (SDL)

Before submitting a pull request:

• No sensitive data in commits
• No hardcoded credentials
• Input validation implemented
• SQL injection prevention verified
• XSS prevention implemented
• Authentication/authorization checked
• HTTPS enforced
• Dependencies updated
• Security tests passed

In case of a security incident:

1. Immediate Action: Contain the incident
2. Assessment: Evaluate the impact
3. Notification: Inform affected parties
4. Remediation: Fix the vulnerability
5. Post-Incident: Review and improve processes

For security-related questions or concerns:

• Email: [your-email@example.com]
• Response Time: Within 48 hours

We appreciate the security research community and thank all researchers who responsibly disclose vulnerabilities.
