Database forensics is becoming more important for investigators with the increased use of information system. Although various database forensic methods such as log analysis and investigation model development have been studied, among methods, recovering deleted data a key technique in DB tampering anti-forensics. Previous studies mainly focused on transaction or journal to recover data, but if...

Monitoring a large number of SQL Servers in an enterprise is a difficult task. The SQL Server administrators have to deal with a large amount of very dynamic and diverse information, and many other complicating factors. We found that the age-old principle of management by exception provides an effective framework in organizing our monitoring efforts. This paper describes our experience in using...

We present a scalable distributed database system called SD-SQL Server. Its original feature is dynamic and transparent repartitioning of growing tables, avoiding the cumbersome manual repartitioning that characterize current technology. SD-SQL Server re-partitions a table when an insert overflows existing segments. With the comfort of a single node SQL Server user, the SDSQL Server user has la...

In this paper, we present a detailed discussion on different SQL injection attacks and their prevention technique. In addition, we proposed a new scheme for prevention of SQL injection attack, which consist of three blocks or three tier architecture: the clients, the application server and the database server. Our protective layer works between the clients and application server. Therefore, bef...

SQL injection attacks are often found within the dynamic pages of a web application that exploit the security vulnerability of the database layers of an application. In this attack category a specifically crafted SQL command is entered in the form field of a web application instead of the expected information. SQL injection takes advantages of the design flaws in poorly designed web application...

SD-SQL Server is a scalable distributed database system. Its original feature is dynamic and transparent repartitioning of growing tables. It avoids the cumbersome manual repartitioning necessary with current technology. SD-SQL Server re-partitions a (distributed) table when an insert overflows existing segments. To its user, SD_SQL offers the comfort of a single node, while allowing the larger...
