A Survey of Access Control and Data Encryption for Database Security

With the vast amount of data generated nowadays, organizing and managing of these data are very important to allow the users to access, retrieve, and update their data by using database systems (DBS). Most of the current organizations use DBS to increase the efficiency and the productivity of their organizations, but the security threats are becoming more dangerous to the DB. So, protection of data by keeping it integrated and secured from any undesirable intrusion became the highest priority for these organizations. DB security provides various techniques to protect data from any threats. This paper discusses two techniques used in the DB field to achieve integrity and confidentiality of the data, by using access control policies and data encryption.
