NFS and HPUX File and Dir SECURITY

[baddou_1]

Hello
I have an existing application that is not secured and cannot be modified
Architecture:
CFT turn on windows environment
Oracle turn on HPUX environment

Those applications is related with one net drive shared with NFS
When CFT programme receive the file, it’s created in the net drive
Then oracle application in UNIX read this file in order to insert transactions in a database
The permission on those directories gives users possibility to view files contents

First, i want that users in HPUX permission can just create files but cannot view or copy … them.
If you have any idea, I will be grateful

Thanks
