NuFW - An authenticating firewall

NuFW adds user-based filtering to Netfilter, the state of the art IP filtering layer from the Linux kernel. Its exclusive algorithm allows authenticated filtering even on multiuser computers.

NuFW can be seen as an Identity access management solution, at the network level.
