As an increasing number of organizations become dependent on access to their data over the Internet, the need for adequate security measures is becoming more and more critical. The most popular security measure these days is a firewall. However, a firewail is not immune to penetr

Investigative Data Warehousing and Mining for Database Security

In this study a preliminary investigative data warehouse is developed to integrate and store very detailed audit data from multiple data sources to support a comprehensive view of database usage and potential security breaches. The data warehouse was populated with real usage dat

Title: Adaptation Concepts for Mobile Database Security

Mobile work including mobile devices and wireless links comprehends a row of problems concerning security issues like availability, conndentiality, and accountability. Mobile processed information in database systems are distributed, heterogeneous , and replicated. They are endan

A Dynamic Approach for Database Security

The growth of the Database domain and the wide Internet has been revolutionized over many years, a large number of people interact through information over the internet. This rapid change and the cost effectiveness of new evolving technologies are providing large opportunities fo

Database Security Protection Via Inference Detection

Access control mechanisms are commonly used to provide control over who may access sensitive information. However, malicious users can exploit the correlation among the data and infer sensitive information from a series of seemingly innocuous data access. In this paper, we propos

A two-phase encryption scheme for enhancing database security

In this article, we propose a two-phase encryption algorithm for data base systems. The system, a record-oriented cryptosystem, allows the encryption and decryption of fields within a record by means of writing and reading subkeys of fields. In addition, we develop two algorithms
