This has brought to light the necessity of strengthening security measures. There have been multiple incidents of attackers acquiring access to information, holding providers hostage with distributed denial of service attacks, or accessing the company’s network by compromising the application. The Bundesamt für Sicherheit in der Informationstechnik (BSI) has published a comprehensive set of information security principles and standards that can be utilized as a solid basis for the development of a web application that is secure. The purpose of this thesis is to build and construct a secure web application that adheres to the requirements established in the BSI guideline. This will be done in order to answer the growing concerns regarding the security of web applications. We will also evaluate the efficacy of the recommendations by conducting security tests on the prototype application and determining whether or not the vulnerabilities that are connected with a web application that is not secure have been mitigated.…
