The Botnet Filtering feature allows you to block connections to or from Botnet command and control servers and to make custom Botnet lists.
We also now have an option to download the Botnet list from a server using HTTPS and FTP protocols. Resolution For understanding the complete Botnet Filter configuration, please use the KB: How To Configure Botnet Filtering With Firewall Access Rules With SonicOS 6.5.2, username and passwords for HTTP URLs in the dynamic Botnet configuration are accepted, and the information is transmitted in the HTTP header so the firewall has the required information. To configure this feature: Navigate to MANAGE | Security Configuration | Security Services | Botnet Filter. Click on Dynamic Botnet List Server. Select Enable Botnet list download periodically. This option is not selected by default. Select the frequency of downloads from Download Interval: 5 minutes (default), 15 minutes, 1 hour or 24 hours. The firewall downloads the Botnet file from the server at the specified interval.
Select the protocol in which the firewall has to communicate with the backend server to retrieve the file from Protocol: FTP (default), HTTPS
Enter the IP address of the server to which the Botnet list file will be downloaded in the Server IP Address field.
Enter the login ID the firewall is to use to connect to the server in the Login ID field.
Enter the password the firewall is to use to connect to the server in the Password field.
Enter the directory path the firewall from which the firewall retrieves the Botnet file in the Directory Path field. This server directory path is relative to the default root directory.
Enter the name of the file on the server to be downloaded in the File Name field.
Click ACCEPT. To view the downloaded list: Navigate to MANAGE | Security Configuration | Security Services | Botnet Filter. Navigate to the Dynamic Botnet List tab. You can manually download the list immediately by clicking on the Download button or after the download interval, the IP addresses from the list will start showing up on this page. You also have an option to Flush the entries downloaded via Dynamic Botnet List Server. Any errors or misconfiguration can be seen on the button next to the Flush that explains what features are necessary to be ON for this to function as well when the next download is scheduled. NOTE: When Dynamic Botnet List Server is configured, the SonicWall first inspects this list and when none of the IP matches, it checks the Botnet database from the back end to take further actions.
