Daily Palo Alto Networks Reports

Hi Guys,

I have a question about PA Daily Networks Report.

On the last report we ran, the top five URL categories were the below

web-advertisements 4,582

proxy-avoidance-and-anonymizers 162

unknown 70

malware 65

games 20

Can anyone please help me to understand

Web advertisements as the top URL - does PAN have an explanation for this category?

Unknown - Why/how are URL listed as unknown.

For the Unknown categories, I assume the database doesn't contain the categories users were browsing, but my customer was not quite satisfy with this unknown categories showing in the top five categories.

Hello Mel,

You may follow this discussion thread: Re: URL Filtering Category is "Unknown"

By default, any newly registered domain will be "unknown" in PAN-DB until Palo Alto Networks reviews, either manually by the analysis/threat team, or through the crawler (triggered on some event). Once an "unknown" is seen on the Palo Alto Networks servers, it will be put into a prioritized queue for crawling and classification. Once Palo Alto Networks determines a category, it will be included in the next database refresh.

Enable global setting to force dynamic-url lookup:

# set deviceconfig setting url dynamic-url yes

# commit

You may clear the cache with CLI command:

> clear url-cache all

Hope this helps.
