One of the challenges when developing mobile applications is security. Whenever you create a mobile app for a business, you need to ensure that it is protected from any type of cyber attack . In the event of a security breach, the company in question may suffer from a bad reputation.
If you do not ensure the security of user data, it could be manipulated or stolen and misused. A poorly secured application can also be infected by a virus, or even cloned. Your efforts would benefit ill-intentioned people, who would simply play around with your security gaps.
Eliminate server-side vulnerabilities
Any communication between an application and a user, which takes place outside of a mobile phone, is mainly done using a server. These servers are a prime target for hackers .
It happens that the developer does not take precautions on the server side, which is when security problems appear. Sometimes vulnerabilities arise from cross-platform development and compilation, which can also lead to security issues.
Start by scanning your applications using an automatic scanner: you will be informed of vulnerabilities that may affect your application. If you don’t, hackers will start with that, and will easily find flaws to hack your application.
If you do not know how to fix these flaws, you can commission a computer security professional.
Secure data storage
If the stored data is easily accessible, manipulated, and usable, your application is at risk of data leakage. Pirates are fond of this information, sometimes resold at exorbitant prices on the black market. The damage to the reputation of a company, or its application, is often terrible.
In addition to the already existing encryption, provided by the operating system, you can add a second layer of encryption on this sensitive data: you will dramatically increase the security of your application!

Consider strong authentication
This is one of the most important security points: a weak level of authentication can lead to vulnerabilities in your mobile application.
Classic authentication is of course provided by a password, so it is essential that you have a strong password policy, so that it cannot be hacked easily.
With multi-factor authentication, you can further secure your application. Also consider that you can offer your users to do this using biometrics.
Prevent client-side injection
Just as we have talked about, information security on both the client side and the server side must be protected no matter what. But there is also a possibility of executing malicious code on the client side.
In fact, there are malicious bots that grab the malicious code into the mobile app through different means. Most of the time, the mobile app treats this code like other data that exists on that device. During processing, this code will cause a context switch and the software will be able to reinterpret any data as executable data. This data may be processed within the framework of users’ access and use rights.
Additionally, client-side injection can be done via binary attacks . You can guard against such injection vulnerabilities by identifying the ingress sources. Next, identify the data provided by the user or the application, and subject that data to validation, which disallows code injection. Moreover, you can analyze the code to check whether the application handles the provided data correctly, to ensure the security of the application
