Abstract

Firewalls protect hosts in a corporate network from attacks. Together with the surrounding network infrastructure, they form a complex system, the security of which relies crucially on the correctness of the firewalls. We propose a method for specification-based testing of firewalls. It enables to formally model the firewalls and the surrounding network and to mechanically derive test-cases checking the firewalls for vulnerabilities. We use a general CASE-tool which makes our method flexible and easy to use.
