This project supports the following versions of dependencies as specified in requirements.txt:

We regularly update dependencies to address security vulnerabilities. Users are encouraged to keep their installations updated to the latest supported versions.

• Template Escaping: All user-generated content automatically escaped using Django's |escape filter
• JavaScript Sanitization: Client-side HTML escaping function prevents script injection
• Safe Content Rendering: User messages inserted as text content, not HTML
• Data Attribute Security: All HTML data attributes properly escaped to prevent breakout attacks

• Django CSRF Tokens: All forms include CSRF protection tokens
• AJAX Request Security: CSRF tokens included in all asynchronous requests
• Token Validation: Server-side validation of all POST requests

• OAuth Integration: Secure Google OAuth 2.0 authentication via django-allauth
• Session Management: Django's secure session handling with proper expiration

• User Validation: All user inputs validated and authenticated

• Message Length Limits: 500-character maximum for guestbook messages
• Content Filtering: Real-time validation of user input
• SQL Injection Prevention: Django ORM provides automatic protection
• File Upload Security: No file uploads in guestbook to prevent malicious uploads

• Content Security Policy (CSP): Comprehensive CSP implementation via django-csp
• HTTP Strict Transport Security (HSTS): Force HTTPS connections

• API Token Management: Secure GitHub and WakaTime API token handling
• Request Validation: All API requests properly validated and sanitized

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

1. Do not disclose the vulnerability publicly
2. Send details of the vulnerability to hi@errorweb.ir
3. Include the following information:
   • Description of the vulnerability
   • Steps to reproduce
   • Potential impact
   • Any suggestions for mitigation

• You will receive an acknowledgment within 48 hours
• We will investigate and provide a timeline for resolution
• We will keep you updated on the progress
• Once resolved, you will be credited for the discovery (unless you prefer to remain anonymous)

For less critical issues, please open a GitHub issue with the "[Security]" prefix.

When deploying this project, we recommend:

1. HTTPS Configuration

   • Use HTTPS exclusively in production
   • Configure proper SSL/TLS certificates
   • Enable HSTS headers for forced HTTPS

2. Environment Security

   • Store all sensitive data in environment variables
   • Use strong, unique SECRET_KEY values
   • Rotate API keys and tokens regularly
   • Never commit secrets to version control

3. Database Security

   • Use strong database passwords
   • Implement database connection encryption
   • Regular database backups with encryption
   • Restrict database access to application servers only

4. Server Configuration

   • Keep server software updated
   • Configure proper file permissions
   • Implement fail2ban or similar intrusion prevention
   • Regular security patches and updates

5. Monitoring & Logging

   • Enable security event logging
   • Monitor for suspicious activities
   • Set up alerts for security incidents
   • Regular security audits and penetration testing

1. Content Moderation

   • Monitor message content for inappropriate material
   • Consider implementing profanity filters if needed
   • Regular review of user-generated content

2. Rate Limiting

   • Implement rate limiting for message posting
   • Prevent spam and abuse through request throttling
   • Consider CAPTCHA for additional protection

3. User Management

   • Regular review of user accounts and permissions
   • Audit author-level access periodically
   • Monitor for unusual user behavior patterns

1. Immediate Actions

   • Identify and isolate affected systems
   • Preserve evidence for investigation
   • Notify stakeholders of potential impact

2. Investigation Process

   • Determine scope and impact of incident
   • Identify root cause and attack vectors
   • Document all findings and remediation steps

3. Recovery & Prevention

   • Implement fixes and security improvements
   • Update security procedures and documentation
   • Conduct post-incident review and lessons learned

Thank you for helping keep our project secure.

The following security tests are recommended for ongoing validation:

1. XSS Testing

   # Test script injection in guestbook messages
   # Verify all user input is properly escaped
   # Validate JavaScript sanitization functions

2. CSRF Testing

   # Verify CSRF tokens in all forms
   # Test AJAX request protection
   # Validate state-changing operations

3. Authentication Testing

   # Test OAuth flow security
   # Verify session management
   # Validate permission controls

Current security implementation status:

• 2021-06-16: Comprehensive XSS protection implemented in guestbook
• 2021-06-16: CSRF protection validated across all forms
• 2021-06-16: Input sanitization and validation enhanced
• 2021-06-16: Security headers configuration updated
• 2021-06-16: Authentication and authorization controls verified
