    沙箱的操作原理請參考以下說明.

    How Does Sandbox Work ?

    The Anti-Malware examines file for threats before deciding to block or pass to Sandbox 


    If the file is never seen, the device copies and send file to Sandbox 
    - The analysis can take up to 15 minutes, so the device allows the file pass the traffic
    - The device can not block this threat until getting the Sandbox’s feedback  


    The file with threat will be identified once it comes again.
    Once the gateway detect the file again, the gateway can identify the file and take the action based on the previous analysis result on local cache. The gateway doesn’t send the file to Could Sandbox again. The local cache will be deleted when the device reboots.
