How to protect from slowloris ?

I have installed mod_antiloris and mod_qos and acunetix still warn about slowloris. mod_antiloris and mod_qos are loaded

Apache/2.2.15 (CentOS) DAV/2 PHP/5.3.3 mod_qos/10.21 mod_antiloris/0.4

    `Loaded Modules:

 antiloris_module (shared)
 qos_module (shared)`

Problem is acunetix still warn me about slowloris even mod_antiloris and mod_qos are running. How to fix it ? – Luka Tce Sep 27 '13 at 16:51
Don't always trust pen-testing tools. Personally, I would attack my own server to test and see if it is working. It probably is working just Acunetix is outdated or just not working – Frank Thornton Sep 27 '13 at 16:59
Acunetix is updated to latest version 8.0 2013 06 26 Trying also to use AcuSensor but can't get it working What filepath i put for file location ./filename if is in root of domain So best is i use .pl file of slowloris ? to test it ? php_value auto_prepend_file ‘[path to acu_phpaspect.php file]’. – Luka Tce Sep 27 '13 at 17:30

I've had success with the mod_reqtimeout module to mitigate that Acuentix flag.


Load the module:

LoadModule reqtimeout_module modules/

Specify for your VirtualHost:

<IfModule reqtimeout_module>
RequestReadTimeout header=10-20,MinRate=500 body=10,MinRate=500
