We have a Java based web application deployed on WebLogic. We provide direct links to some PDF files, which the users can download/ open in their browser. Our security team is claiming that to allow opening PDF files in the browser is security risk. So they want to force the users to download the PDF files first rather than opening them in the browser window.
Is their a way to programmatically prevent the user from opening the PDF files in the browser window and to force downloading the PDF files first?
That totally depends on client-side (i.e., browser) settings over which the web app has no control. I'm having a hard time seeing how opening the PDF in the browser is any more of a security risk than opening it using a standalone app, though.
If I wanted to protect users from PDF vulnerabilities, the first thing I'd do is to delete Adobe Reader from every computer. Any other way of viewing PDFs has got to be more secure (like Preview on OS X, or Firefox's builtin-in viewer).
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
