fstab like mount options for folders

I am looking through and following the Security Documentation on the main Gentoo site. It was talking about Mounting Partitions and the different options one can give each partition such as noexec, nosuid, and nodev. I was wondering if it was possible to give these attributes to folders recursivley as well as to anything that they will ever contain :?:

(not sure if that is included in recursive.) If base linux cannot handle it, is there a program that I could install that could allow me to do this :?:

Thx

Hi,

Maybe I don't get the question right, but...

The mount option is recursivley applyed to the filesystem.
For example if you make a mount-point for /home on /dev/hdaX and
mount it with noexec. All users home dirs and sub folders are noexec.

I am looking at using some of the options that are availible for mount points on folders themselves. I have my system set up so that I only have three mounts them being my swap boot and /. I want to add some of the security that I have mentioned earlier on individual folders rather than using them on mount points.

Hope that explains better.
