Week 16 at a Glance
Intro:

tcp_wrappers used to be "king" in Linux network security. Now a days, a lot of this is more handled within the kernel itself using the various incarnations of firwalling (e.g. ufw, iptables). However, it is still used somewhat and is a lot easier to configure then firewall rules (especially using iptables directly).
