AI-suggested
- Immediately restrict access to NGSurvey to trusted users and networks until a patch is available.
- Implement strict role-based access control (RBAC) and enforce least privilege principles to limit user permissions.
- Conduct thorough code reviews and add robust authorization checks to ensure users can only access their own data.
- Rotate all API keys and refresh tokens to invalidate potentially compromised credentials.
- Enhance monitoring and logging to detect unusual access patterns or data exfiltration attempts.
- Educate users about phishing risks that may arise from leaked PII.
- If possible, isolate NGSurvey instances and segment networks to contain potential breaches.
- Engage with the vendor for timely patch releases and apply updates promptly once available.
- Consider multi-factor authentication (MFA) to reduce the risk of unauthorized access using stolen credentials.
- Perform regular penetration testing and vulnerability assessments focusing on authorization controls.
