Security Management for Distributed Environment
S. S. Jondhale · 2012
A mobile database is a database that can be connected to by a mobile computing device over a mobile network. Mobile processed information in database systems is distributed, heterogeneous, and replicated. They are endangered by various threats based on user's mobility and restricted mobile resources of portable devices and wireless links. Since mobile circumstances can be very dynamic, standard protection mechanisms do not work very well in such environments. So our proposed model enhances the security in mobile database system. In this paper we develop a security model for transaction management framework for peer-to-peer environments. If any attack still occurs on a database system, evaluation of damage must be performed as soon the attack is identified. The attack recovery problem has two aspects: damage assessment and damage repair. The complexity of attack recovery is mainly caused by a phenomenon called damage spreading. This paper focuses on damage assessment and recovery procedure for distributed database systems.
