Intrusion alert normalization method using AWK scripts and attack name database

The current several classes of intrusion alert have various formats and semantics. And it is transferred using a variety of protocols. The protocols that transfer intrusion alert are IDXP, SNMP trap, SYSLOG protocol, etc. These varieties of intrusion alert formats make it difficult to use that together. Intrusion alert normalization makes various intrusions alert to same structure data and same semantics. We need this normalization process to unify alerts from a variety of security equipments. This paper describes how to normalize alerts from several IDS and security equipments.
