This document outlines the security measures implemented in the CMS Project to protect against internal and external threats. The security enhancements cover authentication, authorization, input validation, file uploads, logging, and monitoring.

• Enhanced Password Security: BCrypt password hashing with 12-character minimum length
• Brute Force Protection: Rate limiting (5 attempts per 5 minutes) with 30-minute lockout
• Session Security: Secure, HTTP-only cookies with 2-week expiration
• Role-Based Access Control: Superuser/staff permissions with audit logging
• Multi-factor Authentication Ready: Architecture supports future 2FA implementation

• XSS Protection: HTML sanitization and escaping of user inputs
• SQL Injection Prevention: Parameterized queries and input validation
• Path Traversal Protection: Sanitized file paths and URL validation
• Content Security Policy: Restricts resources to trusted sources only
• File Upload Security: MIME type validation, size limits, and malware scanning

• HTTPS Enforcement: SSL/TLS required in production
• Security Headers:
  • X-Content-Type-Options: nosniff
  • X-Frame-Options: DENY

  • Strict-Transport-Security: max-age=31536000; includeSubDomains
  • Content-Security-Policy with strict directives
• CORS Configuration: Restricted cross-origin requests

• Database Encryption: PostgreSQL with encrypted connections
• Sensitive Data Masking: Audit logs redact sensitive information
• Secure File Storage: Uploaded files validated and stored with random names
