Security and Data Privacy in Redux Stores

Abstract

In large-scale web applications, Redux has essentially become the main tool for managing state in a predictable way, thus, developers can easily handle complex data flows. On the other hand, with front-end applications handling more and more sensitive data, the question of how to ensure the security and privacy of data stored in Redux has, by far, become the most important issue. This research identifies the different risks that come with improperly managing the state, such as, for example, unauthorized data exposure, session hijacking, and tampering with confidential information. The goal is first and foremost to find out the vulnerabilities in Redux-based architectures and then come up with easy-to-implement privacy-preserving techniques to counteract them.Our plan of action is to combine secure coding practices, encryption of state, authentication layers, and controlled access mechanisms so as to upgrade the resistance of client-side state management to attacks. An in-depth case study shows how these measures can be put into practice in a typical web application, thus, proving that they can be efficient in protecting user data without causing a drop in performance or developer productivity. Results show that despite structural advantages given by Redux in managing state, security issues arise due to its openness, i.e. intentional security design is necessary to avoid data leakage and ensure user trust. The main points of this paper are encryption, token-based authentication, and minimum persistence of sensitive information, thus, the work sets the pace for developers to secure Redux stores in line with contemporary data protection ‌standards.
