Database security is one of the most important issues for any organization, especially for financial institutions such as banks. Protecting database from external threats is relatively easier and a number of effective security schemes are available in market. Existing security policies are inadequate to prevent the attacks from insiders (trusted users) and require human intervention in some form or other to detect unauthorized transactions.eg Oracle vault. This paper addresses this issue and proposes an automated detection and prevention mechanism with minimal/nil human interaction.
