Implementation and analysis of Web application security measures using OWASP Guidelines

Abstract

Web application security is the most important area when it comes to developing a web application. Many web applications having vulnerabilities due to poor implementation of security measures. These web applications will be deployed without fixing the vulnerabilities thus becomes vulnerable to many cyber-attacks. Simple attacks like brute-force and NoSQL injection could give unauthorized access to the user accounts. This leads to user privacy issues which could create huge loss to the organizations. These vulnerabilities can be fixed by implementing the necessary security measures while developing the web application. OWASP (Open Web Application Security Project) is a non-profit organization which gives the severity, impact and prevention methods about Top 10 vulnerabilities in web applications. This research deals with the implementation of bestsecurity practices for Node.js web applications in detail. This research paper proposes the security mechanisms for attacks related to front-end, middleware and backend web development using OWASP suggestions. The main focus of this research paper is on prevention of Denial-of-service attack, Brute force attack, NoSQL injection attack and Unrestricted file upload vulnerability. The proposed prevention methods are implemented in a web application to test the defensive mechanisms against the mentionedvulnerabilities.
