Enhancing the Accuracy of Network-Based Intrusion Detection With Host-Based Context

In the recent past, both network- and host-based approaches to intrusion detection have received much attention in the network security community. No approach, taken exclusively, provides a satisfactory solution: network-based systems are prone to evasion, while host-based solutions suffer from scalability and maintenance problems. This paper presents an integrated approach,...
