Abstract
Self-securing storage turns storage devices into active parts of an intrusion survival strategy. From behind a thin storage interface (e.g., SCSI or CIFS), a self-securing storage sen,er can watch storage requests, keep a record of all storage activity, and prevent compromised clients from destroying stored data. This paper describes three ways selfsecuring storage enhances an administrator's ability to detect, diagnose, and recover from client system intrusions. First, storage-based intrusion detection offers a new obsen,ation point for noticing suspect activity. Second, post-hoc intrusion diagnosis starts with a plethora of normally-unavailable information. Finally, post-intrusion recovery is reduced to restarting the system with a pre-intrusion storage image retained by the sensor. Combined, these features can improve an organization's ability to survive successful digital intrusions.
