Five-Minute Updates for PAN-DB Malware and Phishing URL Categories
The Malware and Phishing URL categories in
the PAN-DB cloud are now updated every five
minutes based on the latest information from the Threat Intelligence
cloud. Firewalls with an active PAN-DB URL Filtering license automatically
benefit from these more frequent URL category updates following
the upgrade to PAN-OS 8.0.
With PAN-DB URL Filtering, the
firewall holds a cache of URLs and their categorizations locally;
when a user accesses a website that is not in the local cache or
if the local cache entry has expired, the firewall queries the PAN-DB
cloud to determine the URL category of the website. At this time,
the firewall will get the very latest categorization for the URL
from the PAN-DB cloud, and will add the new URL to the local cache.
To ensure that the firewall is configured to then block access to
malware and phishing sites based on the latest URL category updates,
take the following steps.
