How to Enhance the Security of ReactJs Web Application in 2020?

Security is a critical aspect of web application success in the competitive world. It is important that all the transactions, comprising customer details, are secured from possible online threats. ReactJs is one of the top-rated frameworks, having the latest security features to eliminate possible security threats. The built-in tools of the framework are powerful enough to eliminate possible threats trying to access the user details in a malicious manner.

In this blog, we have discussed some of the best security tips that will help ReactJs Development Company India to build a secure web application for the users. Considering the end-user requirements & business necessities an array of remarkable security tips are mentioned.

Tips to Boost Security of ReactJs Web Application

1. Secure HTTP Authentication
If your web application includes authentication feature, it is important to make sure it’s secure because the client-side authentication and authorization is usually exposed to multiple security flaws which later damage the application reputation.

  • Make sure to keep token payload small. Higher payload > higher the token size > larger the request when they hit the endpoint > more bandwidth power > the less performing your app.
  • Make sure to implement HTTPS and NOT HTTP. This will ensure your web app has a valid certificate and sends the data over secure SSL connection.

2. Safety against DDoS Attacks
Usually this security threat happens when the web application isn’t secure enough or has some loopholes. Due to this, it is tough to interact with the server causing some functionality to stop. Here are some ways to address this situation during ReactJs Web Application Development:

  • Simply limit the number of requests to a given IP from a specific source.
  • Integrate app-level restrictions to the API.
  • Just make calls on the server and NOT on the client-side.
  • Integrate some tests to secure the app layer.

3. Stop Cross-Site Scripting (XSS) Attacks
XSS has a severe impact as the injected code sent by the hacker will be executed as a genuine app code, giving them full access over the application running in the user’s web browser. It can look simple like:

  • I’m just an innocent code!<script>alert(“Unless I’m not 😈”)</script>

Now the same code with some security from XSS:

  • I’m just an innocent code!&lt;script&gt;alert(“Unless I’m not 😈”)&lt;/script&gt;

As you might know, &lt; and &lt; are interpreted as < and > respectively thus the browser will not confuse the data for code this time. Some more ways to protect are:

  • Using the createElement() API.
  • Using JSX auto escape feature.
  • Using dangerouslySetInnerHTML to set HTML straight from React instead of using the error-prone innerHTML.

4. Block Cross-Site Request Forgery (CSRF) Attacks
Such attacks happen through unauthorized cookies placed within your web application by the hacker. It forces an end user to remove unwanted actions on a web application in which they’re at present authenticated. Get some crucial points to not allow it to happen:

  • Implement JWT tokens for session management.
  • Verify application reads only the stored CSRF tokens.
  • Create relevant token headers by applying an authenticated server request.

5. Secure against Broken Authentication
Once a user enters its authentication details and instantly the app crashes leading to exploitation of credential details. Make sure to integrate the following stuff to not allow it:

  • Apply multi-factor and 2-step authorization.
  • Apply cloud-based authentication for secure access.

6. Security against Libraries and Components
You can hire React developers to avoid any sort of risk involved whenever third-party library, modules, or APIs is used in your web application. Sure, these third-party help a lot in the rapid development of application features but their security flaws might destroy your own app.

  • Always manually update libraries to their newest secure and stable versions.
  • Likewise, fix old versions of the components with the latest ones.
  • Before adding libraries in your web application, make a brief check on the security vulnerabilities.

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 2020?
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.

4. 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?
