security overview
Common Vulnerabilities:
- Unencrypted communications can expose session data to interception.
- Absence of strict authentication may allow unauthorized access or impersonation attacks.
- The platform’s popularity could attract social engineering or phishing attempts targeting children users.
- Potential for denial-of-service (DoS) attacks aiming to disrupt gameplay sessions via connection flooding.
Common Mitigations:
- Implement end-to-end encryption (e.g., TLS) to protect user data during transmission.
- Enforce strong authentication and input validation to prevent unauthorized access.
- Employ rate limiting and IP blacklisting to defend against DoS attacks.
- Educate users and guardians on phishing tactics and encourage safe online behaviors.
