Linux Firewalls with iptables

Network Security is essential to your network to protect yourself from hackers and spammers. Iptables is the client side utility available with all Linux distributions to provide packet filtering. Iptables allows you to develop rule sets to filter packets coming into your system, going out, and being forwarded. Packets can be filtered by port, protocol, IP address and MAC. Iptables also allow filtering based on source and destination IPs and ports. The course will provide you with example scripts that can be immediately applied to your systems. Iptables gives you control of the information traveling through your network.
