BrickHouse is designed to make using the network firewall built in to Mac OS X quick and easy. By using BrickHouse to enable your computer's firewall, you can help prevent unauthorized villians from gaining access to your computer via your internet connection.
BrickHouse also helps you use your firewall to guard against denial of service or resource-based internet attacks. Network attacks will bounce off the firewall to prevent your computer from slowing down or crashing.
