Virtual Hosting With Proftpd And MySQL (Incl. Quota) Secure?

[ToysunStory]

Hi all,

I have installed Debian as described in howto, and virtual postfix and virtual ftp (proftp). Everythings working fine. I set-up my ftp to use directories under /var/www and apache hosts that directory as a domain. But i am curious about the security would be a problem at the apache side. Users can be able to see each others files just because of the virtual accounts not real ones? Or is it secure as much as the real user accounts?

thanks

The virtual users are chrooted to their homedirs and can't leave this chroot jail.
