Usage Guidelines

By default, the system scans viruses on files both uploaded and downloaded using SMB.

If no response action is specified during the initial configuration, the default action block takes effect. If no response action is specified during configuration modification, the action configured last time will be used.

The client/server type of protocols supported by the AV function also applies to the direction.

Upload: The file is sent from a client to a server.
Download: The file is sent from a server to a client.

Connections are generally initiated by a client. To ensure that connections can be established and the AV process can be implemented successfully, configure the zone of the client as the source and that of the server as the destination when you configure the security policy.

Example

# Create profile av_smb, configure AV scanning on files uploaded using SMB, and set the response action to block.

<sysname> system-view
[sysname] profile type av name av_smb
