How to Keep React Native Web Application Secure in 2021?

When developers opt React Native as a platform to build mobile apps, they look for the advantages of one codebase for two platforms, enhanced development speed and benefits of TypeScript. But where is the most important element application security? Many myths are shared over the web related to React Native apps security. In this article, we focus on ReactJs Services security based on features, and explain some risks developers should fix to avoid typical mistakes.

React Native App Architecture

React Native is a cross-platform framework allows writing of native apps. The native app runs JavaScript code with the custom JavaScript engine in a separate thread. It makes use of the source code stored in .jsbundle file, whereas the custom JS engines can have different behaviors.

Bridge is present for the communication between JavaScript engine and native parts of the application. When some events happen in the app native part, they are turned into messages, batched, and later passed to the JavaScript engine. It works a similar way for events from JavaScript engine to a native app.

Tips to Secure React Native Application

1. Secure your HTTP Authentication

If your application includes authentication feature where users log in to create an account, just make sure it’s secure because the client-side authentication and authorization is exposed to multiple security threats which may harm these protocols within the app.

Most prominently, React Native Mobile App Development use one of the following methods to integrate authentication:

  • JSON Web Token
  • OAuth
  • AuthO
  • React Router
  • PassportJs
  • 2. Secure against DDoS Attacks

    Typically this security loophole happens when the application isn’t secure or has some limitations in masking the IPs. Due to this, it becomes difficult to interact with the server creating troubles for services to operate. Here are some ways to stop this:

  • Rate limiting on APIs: Simply limit the number of requests to a particular IP from a specific source. There’s a complete library if you’re using Axios named axios-rate-limit.
  • Add app-level restrictions to the API.
  • Make calls on the server and NOT on the client-side.
  • Integrate tests to secure the app layer.
  • 3. Prevent Cross-Site Request Forgery Attacks

    CSRF attacks occur through unauthorized cookies within app integrated by the attacker or because of the unintended cookies. It forces user to execute unwanted actions on a web application in which they’re authenticated.

    Important points to stop it from happening:

  • Use JWT tokens for session management.
  • Check your application reads only the stored CSRF tokens.
  • Create relevant token headers with authenticated request to the server.
  • 4. Secure against Broken Authentication

    Once the authentication details are entered the app crashes leading to leak of credential data. Make sure you have the following stuff ready to not allow it:

  • Multi-factor and 2-step authorization
  • Cloud-based authentication for secure access.
  • 5. Secure against Libraries and Components

    There’s always a threat present when third-party library, modules, or APIs is used in React app. Definitely they assist us a lot in the rapid development of features but having own set of security flaws might harm your own web application.

  • Try to manually update these libraries to latest secure and stable versions.
  • Similarly, fix old versions of the components with the latest ones.
  • When looking to add libraries in your project, simply consult ReactJs Website Development Company to make a brief check on vulnerabilities if they’re listed and note down the possible solutions.
  • Frequently Asked Questions

    1. Why is ReactJS so popular?

    The core objective of ReactJS is to provide the best possible rendering performance. Its strength comes from the focus on individual components. Instead of working on the entire web app, ReactJS allows a developer to break down the complex UI into simpler components.

    2. Is it worth learning React in 2021?

    ReactJS is very easy to learn and more focused than some other JavaScript framework. Many businesses are shifting or adopting the React library because of the simplicity it provides and ease of use. Ease of Learning React is the best advantage as compared to other popular front-end frameworks like Angular and Vue.

    3. Is ReactJs better than Angularjs?

    Prompt rendering is among the best features of React that gives a significant edge over Angular. The core difference between Reactjs and Angularjs is that React is JS-centric, while Angular 2 remains HTML-centric. JavaScript is far more robust, than HTML that makes ReactJs far more simple, focused and consistent.

    . Do you assure about security & confidentiality of the idea?

    Yes, we sign a strict NDA to protect your application idea & data. Hence, we ensure complete security and privacy of your application development project.

    5. What is your pricing model for web application development projects?

    Hire ReactJs Developers with ReactJs India for react native mobile app development to bring a touch of security for your target audience. We offer diverse development models including monthly, part time, & fixed cost hiring for you to choose from.

    Wrapping Up:

    Web applications written with React Native are well-protected. It has its own cost and additional risks. To make the app secure, make sure to follow the best practices of secure web application development lifecycle. Define and address possible risks, plan your security controls, and prepare a strategy. Invest your time to build a threat model for your web application as it helps to bring together security and usability of the app. Simply consult ReactJs Plugin Development Company to make a brief check on vulnerabilities if they’re listed and note down the possible solutions.
