Combinational Approach for Object Clipping Using GLIP and Protection Against Sql Injection Attacks

Multidimensional databases are being used in a wide range of applications. To meet this fast-growing demand,R+ trees were used that exhibit outstanding search performance. In order to support efficient concurrent access in multiuser environments, concurrency control mechanisms for multidimensional indexing have been proposed. However, these mechanisms cannot be directly applied to the R+-tree because an object in the R+-tree may be indexed in multiple leaves. This paper proposes a concurrency control protocol for Rtree variants(ZR+ trees) with object clipping, namely, Granular Locking for clIPping indexing (GLIP). GLIP is the first concurrency control approach specifically designed for the R+-tree and its variants, and it supports efficient concurrent operations with serializable isolation, consistency, and deadlock-free. A HTTP Analyzer tool is used in order to check whether the HTTP request packets sent by the client web application to the web server were according to the RFC specifications or not. SQL injection is a technique that can give attackers unrestricted access to the databases that underlie Web applications and has become increasingly frequent and serious. This paper presents a new highly automated approach for protecting Web applications against Data base
