are the default configuration options of all the linux distros I've looked at.
also the recommended config from apache.org.
I would add:
install the bandwidth module, which kills the iis specific viruses that consume data transfer by reporting infected machines to one location.
disable any cgi but approved scripts.
do not enable frontpage extentions ( they break security by accessing activex controls )
force download and saving of any file other than html/xhtml/php/xml
( do default opening of pdf )
use moz_gzip
compress all data being transferred, saves data transfer, and stops execution of malicious code until user enables.
