How to allow a specific file extension

L2 Linker

I work for a K-12 school district that uses a program that reads books to students.  The file extension is .kes (KES is a file extension that belongs to Text Files of Kurzweil Educational Systems) and is blocked in our file blocking profile as an Encrypted ZIP file.  Is there any way to allow the .kes file without allowing all Encrypted ZIP files?

Hello Al,

Since PAN does not have an option for file type KSE, you may try with customer signature: Follow the header in packet capture and see the type of  request it is.

Can File Blocking Profiles identify the file extensions? I work in a private secondary school in Portland, OR. What I need is to block all .txt files but one (which is a test instuction for students).

Thank you.
