This tool can generate a Linux Kernel module for custom rules with Netfilter hooking. In case of a attack, the attacker will not be able to find the kernel module that is hidden if you have HiddenWall in your system. 

This is a beginner friendly tool and a low-level programmer can write new templates for the module.
