Architectures for Intrusion Tolerant Databases Based on Role-Based Accesss Control
Wu Zhong · 2006
In face of attacks,it’s very important for database system to protect the key data from intrusions and dynamically locate and repair the damage caused by the intrusions. Nowadays, lots of medium and mini-type network databases have no redundancy to guarantee their availability and survivability. Under the circumstances,we propose a intrusion tolerant database architecture which is of no hardware redundancy revolved and base on the role-based access control. The architecture can provide uninterrupted important services by executing key data in isolated places,can automatically recover the damage on the fly,and can self-transfer the system states and also self-regulate the system parameters base on the users’ roles,history logs and the requirements of intrusion tolerance etc.
