Embedded firewall software package

Firewalls became an indispensable part of computer networks. Corporations buycommercial firewalls or use open source firewall software packages to meet their need.Most of these are Linux or FreeBSD based and few of them are OpenBSD based, whichhas few features or are command line tools. In this thesis, creating an OpenBSD basedfirewall software package, which has a graphical user interface, an extensible infrastructureand targets embedded systems, has been aimed.In this thesis, firstly firewall has been described and then previous studies about firewallsoftware packages have been discussed. Since this study aims OpenBSD operating systemand embedded hardware, the basics of OpenBSD and the design decisions for an embeddedsystem have been discussed. Finally the infrastructure of the implementation of this studyhas been explained.
