External Dynamic Malicious URL List

In addition to querying predefined categories, configuring the blacklist, whitelist, and user-defined URL categories, enabling malicious URL detection and low-reputation detection, the FW can filter URLs based on the external dynamic malicious URL list. The external dynamic malicious URL list is a text file of malicious URLs released by external official websites. By updating the external malicious URL signature database, the FW downloads the latest external dynamic malicious URL list from the external official websites and loads it to its cache. When the FW is enabled with filtering of external dynamic malicious URLs, the FW matches the requested URL with the external dynamic malicious URL list in the cache. If the URL matches the list, the FW blocks the URL request. In addition, a web push page that is the same as that in the blacklist is displayed on the browser of the requester. The pushing information can be edited on the FW. To enable the FW to identify and block the latest malicious URLs in a timely manner, the FW needs to update the external malicious URL signature database from the external official websites to update malicious URLs in its cache. With this function, you can update the malicious URL list based on your requirements. When the malicious URLs are not updated in a timely manner, the malicious URLs cannot be blocked in a timely manner. In this case, you can load an external dynamic malicious URL list so that the FW can identify and block the latest malicious URLs, defending against new attacks.
