SiLK, the System for Internet-Level Knowledge, is a collection of
traffic analysis tools developed by the CERT Network Situational
Awareness Team (CERT NetSA) to facilitate security analysis of large
networks. The SiLK tool suite supports the efficient collection,
storage, and analysis of network flow data, enabling network security
analysts to rapidly query large historical traffic data sets. SiLK is
ideally suited for analyzing traffic on the backbone or border of a
large, distributed enterprise or mid-sized ISP.
