Vous craignez une attaque Proxy, d’injections SQL, faille, infiltrations et bien d’autres!

Il existe un Plugin sous Cpanel qui permet de sécuriser les requêtes HTTP par des règles et directives propres.

C’est donc un module qui se couple avec Apache qui est très robuste et relativement Plug and Play (mais très compliqué à configurer)

Il y a donc moyen de filtrer des chaines de caractères telles que : drop, insert, exec, make, install, qui n’ont rien à faire dans les requêtes HTTP.

Installation

Pour l’installer il faut se rendre dans le WHM, Onglet Software -> EasyApache (Apache Update)

Previously Saved Config

Next step

Next step

Next step

Cochez le “Mod Security” puis “Save and Build” et attendez 10minutes qu’apache se re compile.

Gestion

Relancé le WHM, Onglet Plugins -> Mod Security

Edit config -> Default Configuration -> Save configuration

Et voila votre Mod sécurité bloquera les requêtes un peu spécial/louche avec la configuration par défaut.

Pour ceux qui n’ont pas Cpanel et qui n’ont pas envie de créer leur propres règles :

Je vous conseil l’articles : http://www.tux-planet.fr/installation-et-configuration-de-modsecurity/ (merci pour la tof)

Et la configuration suivante :
