Urgency
🔴 Immediate
Recommended Actions
- Comply with Kiteworks vendor directive: shut down all Kiteworks servers during the specified six-hour maintenance window on Saturday
- Monitor Kiteworks support channels and email for emergency patch release and technical details
- Prepare alternative secure file transfer methods for the shutdown window (e.g., encrypted email, alternative SFTP)
- After patching, review Kiteworks access logs and file transfer logs for suspicious activity preceding the shutdown
- Escalate to leadership: assess whether to keep systems offline beyond the window if patch details are insufficient
