- Network Intrusion Detection Systems (NIDS) capture large amounts of data that is difficult or impractical to report and analyze directly from the capture device. It is also common to have more than one NIDS device and reporting from a consolidated multi-NIDS device. To provide a platform for multi-NIDS device reporting and analysis, this paper describes a consolidated database, or Data Mart design and implementation to store data from multiple Snort NIDS devices. This consolidated Snort Mart is designed for reporting and analysis and can provide a platform for better understanding of NIDS device information
