Why use Guarddog

Easy to use goal oriented user interface. You say what the firewall should do without having to explain all the details of how it should do it.

Application protocol based. Unlike other tools, Guarddog does not require you to understand the ins and outs of IP packets and ports. Guarddog takes care of this for you. This also reduces the chances of configuration mistakes being made which are a prime source of security holes in computer systems.

Doesn't just generate an initial firewall and forgets it. Guarddog is used to maintain and modify the firewall in place.

Can be used in workstation and router configurations.

Allows you to divide your network into groups of machines and control what network protocols are allowed between them.

Works on the older Linux kernel 2.2 series ipchains firewall subsystem, and also on newer Linux kernel 2.4 netfilter/ iptables firewall subsystem.

Takes advantage of advanced Linux kernel 2.4 features such as connection tracking and rate limited logging.
