Key Data Flows and Potential Threats

User Registration:

  • Threats: Brute-force attacks, bot registrations, phishing.
  • Mitigation: CAPTCHA, two-factor authentication, rate limiting on login attempts, monitoring for anomalous activity.

User Authentication:

  • Threats: Password theft, credential stuffing attacks.
  • Mitigation: Strong password hashing with salts, rate limiting on failed login attempts, blocking suspicious IP addresses.

User Data Storage:

  • Threats: Unauthorized access to user data, data loss.
  • Mitigation: Data encryption at rest, access controls, regular backups, data integrity monitoring.

Content Upload:

  • Threats: Uploading malicious content, DDoS attacks.
  • Mitigation: Scanning uploaded files for malware, limiting file upload sizes, using a CDN to distribute the load.

Content Access:

  • Threats: Unauthorized access to content, content piracy.
  • Mitigation: Access controls, DRM (Digital Rights Management), watermarks, content usage tracking.

User Interactions:

  • Threats: Spam, hate speech, offensive content.
  • Mitigation: Content moderation, spam filtering, blocking abusive users.

Critical Threats and Mitigation Plan

  • Password theft: Use strong hashing algorithms, two-factor authentication, and regular password audits.
  • Injection attacks (SQL, XSS): Validate and sanitize user input, use prepared statements, and use frameworks with built-in protection against injection attacks.
  • DDoS attacks: Use a CDN, rate limit requests from single IP addresses, and work with your provider to protect against DDoS attacks.
  • Unauthorized access: Implement role-based access control (RBAC), regularly audit access permissions, and monitor for unusual activity.
  • Data loss: Perform regular backups, encrypt data, and have a disaster recovery plan in place.
  • Malware: Scan uploaded files, use web filters, and train employees about cybersecurity threats.
  • Phishing: Create a security policy, train users, and use two-factor authentication.
  • Denial of service: Monitor server availability, scale infrastructure, and have a disaster recovery plan in place.
  • Unauthorized content copying: DRM, watermarks, content usage tracking.
