Efficient Damage Assessment and Repair in Resilient Distributed Database Systems

Abstract

Preventive measures sometimes fail to defect malicious attacks. With cyber attacks on data-intensive applications becoming an ever more serious threat, intrusion tolerant database systems are a significant concern. The main objective of intrusion tolerant database systems is to detect attacks, and to assess and repair the damage caused by the attacks in a timely manner such that the database will not be damaged to such a degree that is unacceptable or useless. This paper focuses on efficient damage assessment and repair in resilient distributed database systems. The complexity of distributed database systems caused by data partition, distributed transaction processing, and failures makes damage assessment and repair much more challenging than in centralized database systems. This paper identifies the key challenges and presents an efficient algorithm for distributed damage assessment and repair.KeywordsDatabase SystemIntrusion DetectionDamage AssessmentTrans ActionDefense Advance Research Project AgencyThese keywords were added by machine and not by the authors.
