Impact of secure programming on web application vulnerabilities

Nowadays all organizations tend to shift their daily business processes into web. This shifting requires from web developer´s detailed knowledge about security techniques, such as Structured Query Language (SQL) injection and Cross Site Scripting Attack (XSS), otherwise the data managed and protected by web application could be exposed to not authorized parties. This paper aims to link and measure the impact of security techniques used by web developers for avoiding the vulnerabilities in web applications. We conducted a survey about the level of applicability of security techniques during web development and conducted a penetration testing for more than 110 local web sites. We discovered many vulnerabilities in these web sites and we linked the results with survey outcome.
