Uma Metodologia para Verificação de Filtros de Pacotes
Abstract
This paper describes a methodology for coherence verification in packet filters. For this purpose, each pair of filtering rules are compared, looking for errors, partial or total redundancy, or for situations that should be further analyzed (warnings). The proposed methodology can be used not only in a single filter but also in hierarchically distributed filters. Stateless and stateful filters are also considered into the verification process.References
