Abstract

This paper presents methods for assessing damage in a database system after an attack is identified and a malicious transaction is detected By using pre-developed data structures our protocols identify all affected transactions and also damaged data items without requiring any log access These data structures are built using bit-vectors and are manipulated using logical AND and OR operations to achieve faster damage assessment.
