Can i block file by file name?

L3 Networker


so, can i? Eg.: i want to allow upload/download .pdf files, but block "hacker tutorial.pdf" file. How i can do that?

Following article explains a way to achieve this  Can Files be Blocked by Name?

Sorry, but this document explains nothing for me.. I read it few times before.. Maybe i missing something..

At the moment, there is no direct method to block files using their names .

Following workarounds can be used:

1> Create a Custom URL category using the source URL of the file and block this custom-url category.

Eg : If you know the URLs where this file "hacker tutorial.pdf" could be downloaded from :

Create a custom URL category and block this category using URL filtering profile.

2> Create custom application signature  for the URL path including the filename.

P.S: "But please keep in mind that once you block the file by filename your users will normally try to change the filename to bypass the control which makes it useless."


Thank you for answer. And i understand that users will normally try to change the file name.


Correct, paloalto is not a DLP product 🙂

Maybe you can try to:

     create URL filtering with "Hacking" for exemple

     Block download from these site.

If sites are in https, keep in mind that you can configure SSL decrytion.
