React Native is based on JavaScript and very easily allows developers to build natively rendered mobile apps for iOS and Android operating systems. Just like any other option of the framework, react native is also vulnerable to attacks and security threats. The analysis from the perspective of a native standpoint needs to take multiple things into account as well as multiple parts of the framework and connections between them. Since the source code of the apps will be available to the client, front-end JS apps are quite vulnerable to being modified or getting sensitive to data breaches. Some of the common issues related to JS apps and react native security are:
- Cross-site scripting: This is known as an XSS attack and is a situation in which the attacker tricks the website into random JS code in the user’s browser. This is bifurcated into 2 options which are reflected XSS attack which will happen when the link with text information is processed by the browser as a code and the other option is stored XSS attack, where the attacker will have server access and will run any random code on the server to generate the information related to client’s webpages.
- Insecure randomness and links: This will always happen when the rendering of the app is done on the side of the servers. This is further based on creating the primary version of the pages which can also generate the documents variable from the JSON strings. This can be dangerous as the data provided in this will be converted into the string which will be visible on the pages.
- ACE (arbitrary code execution): This will happen when the arbitrary command execution is based on the target process using the programs of arbitrary code exploits. This can be harmful as the users of the products can be exposed to the malware.
- ZIL Slip: This problem will happen when the security of the coding will be compromised and the attackers will unzip the malicious coding and files outside the target directory. This will also allow the attackers to even proceed with overwriting the important system and configuration files.
Hence, having a good command of the protection related to React native apps is a very important concern to be taken into account while building the apps. This will help to improve the storage of sensitive information and further will be able to improve the security on the Android and iOS platforms.
Some of the basic ways outs of improving security are:
- Improving the security of App-to-server connection: The communication between the client and server has to be made safe and secure mainly because this is an open-source platform and is vulnerable to threats. Commonly used web services will be HTTPS connection, REST based on HTTPS, and so on. The certificate in this case will serve as the identity proof of the servers. It is very important to note that different users based on separate coding variables should be assigned in this case to real attributes to avoid the mismatch in the authentication of the user credentials. Even a small mismatch, in this case, will be problematic and can create issues with the security of the apps.
- SSL Pinning: This is the protocol related to authentic and encrypted links between the networking computers. The TLS in this case will be there and further will refer to the technique to validate the certifications on the side of the client even after the SSL handshaking. The list of trusted options in this case will be embedded in the client apps during the development so that the connections can be made safe. This will help to make sure that things and connections will be done only with the trusted servers. The desirable options in this case will be used in terms of signing the updated certificates so that the instances of bricking can be prevented.
- Code obfuscation: This is based on the concept of minification and is the primary and initial method of storing sensitive data. This will be based on legible coding which makes it unreadable to the human eyes with the help of software like Uglify. The Java codes on the react native will be stored on the DEX file which is readable unless obfuscated. This concept also comes with an inbuilt library for the transformer systems that allows the users to implement JavaScript coding and native systems. The base of this process will be to understand the grade of the app inside the buildtypes section. This will help to set the Proguardactive files easily and will also indicate the location of the configuration. The configuration will be set and obfuscation will be very well added.
- Advanced React Native Security: There are threats related to this problem based on network requests that will run on multiple devices. The apps that are executed over here will overcome the OS security mechanisms to gain access to the secured storage systems. SafetyNet which is the Android API that helps in the detection of the rooted devices and the bootloader unlocks. The react native plugin in this case can also be used to see if the app is being run on the emulator or not. This will help to improve security easily
- RASP: This is the process of continuously detecting the attacks on the runtime of the apps to protect the apps and improve the storage. This tool is built inside the runtime environment and can analyze the performance as well as the behavior of the app by controlling the execution. This will help to confer the additional layer of security and will work in tandem with other security monitoring tools. The best part is that it will help to monitor the app, detect intrusions, and abnormal behavior, and improve the basic performance as well as the execution concept.
Hence, react native is one of the most popular and efficient app-building frameworks. So, the developers must focus on using all of the security features available on Android and iOS to ensure the protection of the React native apps. With the integration of the best mechanisms, appropriate libraries and APIs will be taken into account so that the incidence of the risk will be perfectly reduced.
