The rapid development phases and extremely short turnaround time of Web applications make it difficult to eliminate their vulnerabilities. Here we study how software testing techniques such as fault injection and runtime monitoring can be applied to Web applications. We implemented our proposed mechanisms in the Web Application Vulnerability and Error Scanner (WAVES)-a black-box testing framework for automated Web application security assessment. Real-world situations are used to test WAVES and to compare it with other tools. Our results show that WAVES is a feasible platform for assessing Web application security. (c) 2005 Elsevier B.V.

This work has demonstrated that the addition of an optimum content of dimethyldioctadecylammonium chloride (DDAC)-modified montmorillonite clay (Dclay) enhances the ionic conductivity of the plasticized poly(methyl methacrylate)-based electrolyte by nearly 40 times higher than the plain system. Specific interactions among silicate layer, carbonyl group (C=O) and lithium cation have been investigated using Fourier-transform infrared (FTIR), solid-state NMR, alternating current impedance. The FTIR characterization confirms that both of the relative fractions of 'complexed' C=O sites and 'free' anions increase with the increase of the Delay content, indicating that strong interaction exists between the C=O group and the lithium salt. In addition, the solid-state NMR demonstrates that the interaction between the PMMA and the clay mineral is insignificant. The addition of clay mineral promotes the dissociation of the lithium salt and thus, the specific interaction can be enhanced between the C=O and the free lithium cation. However, the balanced attractive forces among silicate layers, C=O groups, lithium cations and anions is critical to result in the higher ionic conductivity. (C) 2002 Elsevier Science Ltd.
