Intrusion tolerance for Internet applications

Abstract

The Internet has become essential to most enterprises and many private individuals. However, both the network and computer systems connected to it are still too vulnerable and attacks are becoming evermore frequent. To face this situation, traditional security techniques are insufficient and fault tolerance techniques are becoming increasingly cost-effective. Nevertheless, intrusions are very special faults, and this has to be taken into account when selecting the fault tolerance techniques. © 2004 Springer Science + Business Media, Inc.
