Configuring Filtering of External Dynamic Malicious URL

The FW can filter URLs based on the external dynamic malicious URL list. By updating the external malicious URL signature database, the FW can periodically download the external dynamic URL list from the external official websites and import the list to its cache. The FW that is enabled with filtering of external dynamic malicious URL can identify and block malicious URLs.

Updating the External Malicious URL Signature Database: By updating the external malicious URL signature database, the FW can identify and block the latest malicious URLs in a timely manner, defending against new attacks.

Enabling Filtering of External Dynamic Malicious URLs: 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 external dynamic malicious URL list in the cache, the FW directly blocks the URL request. By default, filtering of external dynamic malicious URLs is disabled. The user-defined URL category, external dynamic malicious URL, malicious URL and low-reputation URL are in descending order of priority.
