HiddenWall – Create Hidden Kernel Modules

HiddenWall – Create Hidden Kernel Modules

HiddenWall is a Linux kernel module generator used to create hidden kernel modules to protect your server from attackers. It supports custom rules with netfilter (block ports, hidden mode, rootkit functions etc).

The motivation is basically another layer of protection, much like a hidden firewall – setting securelevel to 2 on BSD would have a similar effect.

In a typical attack, the bad actor can alter your IPTables or UFW rules – with HiddenWall you still have another layer that can block external access because it hooks directly into netfilter from kernel land.
