HiddenWall
hidden firewall, custom firewall in kernel
...The motivation: on bad situation, attacker can put your iptables/ufw to fall... but if you have HiddenWall, the attacker will not find the hidden kernel module that block external access, because have a hook to netfilter on kernel land(think like a second layer for firewall).
My beginning purpose at this project is protect my personal server, now is protect the machines of my friends. When i talk "friends", i say peoples that don't know how to write low level code. Using the HiddenWall you can generate your custom kernel module for your firewall configuration.
