FortiGate Cloud – SandBox

SandBox

FortiSandbox Cloud is a service that uploads and analyzes files that FortiGate AV marks as suspicious.

In a proxy-based AV profile on a FortiGate, the administrator selects Inspect Suspicious Files with FortiGuard Analytics to enable a FortiGate to upload suspicious files to FortiGuard for analysis. Once uploaded, the file is executed and the resulting behavior analyzed for risk. If the file exhibits risky behavior or is found to contain a virus, a new virus signature is created and added to the FortiGuard AV signature database. The next time the FortiGate updates its AV database it will have the new signature. The turnaround time on Cloud SandBoxing and AV submission ranges from ten minutes (automated SandBox detection) to ten hours (if FortiGuard Labs is involved).

FortiGuard Labs considers a file suspicious if it exhibits some unusual behavior, yet does not contain a known virus (the behaviors that FortiGate Cloud Analytics considers suspicious change depending on the current threat climate and other factors).

The FortiGate Cloud console enables administrators to view the status of any suspicious files uploaded: Pending, Clean, Malware, or Unknown. The console also provides data on time, user, and location of the infected file for forensic analysis. SandBoxing is available in both free and paid FortiGate Cloud subscriptions.

You can view the FortiSandbox Cloud Service Description for details.

The SandBox tab collects information that the FortiSandbox Cloud service compiles. FortiSandbox Cloud submits files to FortiGuard for threat analysis. You can configure your use of the service and view analyzed files’ results.

You must enable Cloud SandBoxing on the FortiGate and submit a suspicious file for the SandBox tab to become visible.
