Item Dynamic Content Security Policy Generation at Client-Side to Mitigate XSS Attacks(Institute of Electrical and Electronics Engineers Inc., 2024) Singh, R.P.; Chandavarkar, B.R.Cross-site scripting (XSS) attacks are a major threat to web applications and have consistently ranked among the OWASP Top 10 vulnerabilities. Attackers can inject malicious scripts that execute within a user's browser. Server-side Content Security Policies (CSPs) offer some protection, but their static nature makes them ineffective when dealing with dynamic content and a very small percentage of web application use. This paper explores dynamically generated CSPs on the client side. This approach overcomes the limitations of traditional CSPs and provides a more robust defense against XSS attacks. © 2024 IEEE.Item Plasma nitriding of AISI 2205 steel: Effects of surface mechanical attrition treatment and chemical etching(Maney Publishing michael.wagreich@univie.ac.at, 2016) Gatey, A.M.; Hosmani, S.S.; Arya, S.B.; Figueroa, C.A.; Singh, R.P.In the present study, surface mechanical attrition treatment (SMAT) and plasma nitriding were conducted on AISI 2205 steel. SMAT was effective in enhancing the surface hardness of the steel by about 80%. The influence of SMAT on the corrosion behaviour of the steel was studied in a 3.5 wt-% NaCl solution. Due to the stable and thicker passive layer, improved corrosion resistance was observed for the SMATed steel. However, nitrogen diffusion during plasma nitriding was impeded by the improved passivation, especially for the lower duration (30 min) of chemical etching/cleaning (i.e. sputter cleaning in hydrogen plasma) of the specimen's surface. Furthermore, high chemical etching duration (120 min) resulted in improved surface hardness and nitriding kinetics. © 2016 Institute of Materials, Minerals and Mining.Item Role of surface mechanical attrition treatment and chemical etching on plasma nitriding behavior of AISI 304L steel(Elsevier B.V., 2016) Gatey, A.M.; Hosmani, S.S.; Figueroa, C.A.; Arya, S.B.; Singh, R.P.In the present study, the effect of surface mechanical attrition treatment (SMAT) on corrosion resistance and plasma nitriding behavior of AISI 304L stainless steel (SS) was investigated. Mechanical twins and deformation induced martensite phase were observed in the SMAT affected region. SMAT improved the corrosion resistance and nitriding kinetics of AISI 304L SS. Effective nitriding time and hence, the thickness of the nitrided layer were increased with increase in the duration of chemical etching and a decrease in the stability of passive layer on the SMATed specimens. Surface hardness of the nitrided specimens was dependent on the formation of expanded austenite (?N) and its decomposition (especially, at higher effective nitriding time). © 2016 Elsevier B.V.
