Modeling Network Intrusion Detection Alerts for Correlation
Overview Signature-based Network Intrusion-Detection Systems (NIDSs) often report a massive number of simple alerts of low-level security-related events. Many of these alerts are logically involved in a single multi-stage intrusion incident and a security officer often wants to analyze the complete incident instead of each individual simple alert. This paper proposes a well-structured model that abstracts the logical relation between the alerts in order to support automatic correlation of those alerts involved in the same intrusion. The basic building block of the model is a logical formula called a capability. The paper use capability to abstract consistently and precisely all levels of accesses obtained by the attacker in each step of a multistage intrusion. The paper then derives inference rules to define logical relations between different capabilities.
