A developing of signature-based network security tester for NGSS

This paper presents the testing tool that automatically generates attack traffic. Existing test equipments for network security systems are very expensive and difficult to use. We have designed and implemented NST (network security tester) that generate attack traffic using the signature of the snort network-based intrusion detection system. A set of attack packets is created from the database according to the pre-designed test scenario then transmitted to a target system. The proposed system shows useful features such as an attack information database, a scenario writing, a TCP session attack and high parsing success rate.
