Securing OLAP data cubes against privacy breaches
Lingyu Wang,Sushil Jajodia,Duminda Wijesekera +2 more
- 09 May 2004
TL;DR: A flexible framework for specifying authorization objects in data cubes and the proposed method eliminates both unauthorized accesses and malicious inferences is devised, which requires little modification to existing OLAP systems.
Secure dynamic fragment and replica allocation in large-scale distributed file systems
TL;DR: It is formally prove that, assuming read-write patterns are stable, the algorithm converges toward an optimal file allocation, where optimality is defined as maximizing the file assurance.

Surviving information warfare attacks on databases
Paul Ammann,Sushil Jajodia,C.D. McCollum,B.T. Blaustein +3 more
- 04 May 1997
TL;DR: It is shown that consistency preserving normal transactions maintain database consistency in the presence of damage, and an algorithm for taking consistent snapshots of databases under attack is presented, which has the virtue of not interfering with countermeasure transactions.
