[CentOS] sticky folder permissions

Hi

I have a situation where i need to blanketly allow read permissions on 
/opt to any user at all.

I have some bad behaving apps though that seem to overwrite these 
permissions and do not set world read on their log directories.

Is there any way i can make /opt world readable and make sure these 
permissions stick to all subfolders and not allow users other than 
root/sudo to change them?

thanks
