Blocking images with EXIF data

Blocking images with EXIF data

I have a customer that wants to block outbound images that have EXIF data (gps coordinates).  Can this be accomplished with a customer app-id doing a pattern match perhaps?

Hello chrisdduncan,

Yes if the customer can create a custom application after analyzing the data pattern and loading that as a signature in the custom app and block it as needed.

I have seen in file blocking profile that I do not find a file type exif. But if this can be caught as a signature then yes we can have control over it.

Please send me a PM (or even better put it online in this thread :-) in case somebody has already created such IDS signature for PA. That is images containing EXIF data (or more specific containing geolocation EXIF data).

I would suggest to post the question in dev center community.

It is"the online community for customers, partners, and employees to share custom content including Custom App-IDs, Custom Threats, Custom Reports, XML API integration, CLI scripts, and other tools. Use the discussion threads to ask questions and receive help from other members. The current samples would be a good start. "

There might be someone already who has worked on this app. Also you can submit a request for new app. The following link explains on how you can do that

Hope this helps.

I guess it's not possible to do pattern match because what you'll do here is to look for EXIF tag IDs for GPS but they are less than 7 bytes.

0x8825 : GPSInfoIFDPointer

0xF4240 : GPSVersionID
