To protect your server from DoS attacks on te webserver you might want to install mod_evasive.
Attention: Some CalDAV clients really bomb the server the fetch data. If you experience problems after installing mod_evasive disable it or try less strict settings
Install the Debian package:
$ apt-get install libapache2-mod-evasive
Add the module to Apache:
$ a2enmod evasive
Edit /etc/apache2/mods-enabled/evasive.conf and enter the following:
<IfModule mod_evasive20.c>
DOSHashTableSize 3097
DOSPageCount 100
DOSSiteCount 100
DOSPageInterval 15
DOSSiteInterval 15
DOSBlockingPeriod 60
</IfModule>
We tested this configuration it works well with Group-Office.
