....furthermore perform computationally intensive pattern searches on the application level payload. A system with a multi layer inspection unit offers a higher level of security than a traditional firewall. However, due to their complexity, such systems are slower and require better administration [3]. 2 Young H. Cho et al. 1.1 Motivation There are several rule based multi layer inspection firewall software packages available today. Most of these systems use one or more general purpose processors running rule based packet filtering software. Due to exhaustive pattern detection algorithm, ....

....4 with a summary of our research. 2 Software Firewall Several software based firewall units provide complex rule based multi layer inspection routine in addition to other security protocols. These firewall units can detect malicious packets that are not filtered out by simple header inspection [3]. In this section we describe the design structure of software stateful multi layer firewall package. 2.1 Libcap based system Libcap is a portable library of functions that can capture network packets and examine their length, contents, and header information. The result from the library ....
