Most people have the misconception that data security for mobile apps is a feature or advantage. Well, it has become an abstract necessity. One small misstep or outage can cost your organization a lot of money and a lifetime of trust. That’s why information security should be prioritized when coding your mobile app. Therefore, mobile apps and data security must go side by side.

Today, in this constantly changing world of technology and online platforms, the role of mobile apps has evolved to turn the most difficult tasks into easier ones. We, tech-savvy folks, love to explore more and more advanced features in mobile apps.

So, what you need to do as an app developer is to develop useful and trustworthy mobile apps keeping in mind all the security concerns of mobile apps.

What is Mobile Application Security?

Using standard security protocols, mobile application security protects applications from external risks such as viruses and other cyber threats. This malware and cyber threat can expose financial and other sensitive data to hackers.

Mobile application security has also become critical in today’s digital world. Hackers may obtain users’ personal information through mobile phone security holes. Implement security protocols while developing mobile applications to ensure users’ data cannot be leaked or misused.

Considerations of Mobile App Development

If you have currently developed one or have an idea for a commercial app, the world could be just your oyster. Mobile apps and devices often rely on consumer data, including contact information, location, photos, and more, all vulnerable to data breaches, digital snooping, and theft.

Protect the app with code encryption.

As a mobile or web application developer, you know how to generate source code, but simple coding errors or code failures in testing can leave room for bugs or vulnerabilities in your application. Hackers could exploit this vulnerability to tamper with or reverse engineer the code by obtaining the public version of the application.

Encryption is a method of scrambling the text of a code until it becomes a bunch of letters of the alphabet and means nothing to anyone without the key. This protects your application code because even if the data is stolen, thieves cannot understand it, preventing them from misusing it.

Use the Authorization API

Remember always to use the API declared in the application code. It always gives hackers privileges to use your information; for example, hackers can use a cache of authorization information to gain authentication on the system. Experts recommend centralizing authorization across APIs to maximize mobile app security.

Conduct a thorough security check.

You will likely test your app for functionality and usability before launching it. Still, you should also perform mobile app security testing to find any vulnerabilities or bugs. Even after an application is released, your security team should regularly test the application to find and fix any bugs and keep the application secure.

Application and software development teams skip this step to speed up application startup. Still, remember that any bugs in your application could pose a potential security threat to you and the application’s users.

Securing your application is an ongoing process; these tests should be performed periodically to detect threats. You can consult a network security expert or a penetration tester to conduct a penetration test and vulnerability assessment of your network to ensure your data is well protected.

Secure the backend

You may have security measures on the client-server front end, but protecting your backend server from malicious cyber attacks is also necessary. This prevents unauthorized access and data leakage of application servers and databases.

Ensure data is stored securely.

Database and privacy laws will continue to change due to growing consumer mistrust and more than 27 online privacy bills introduced or passed by state legislatures. However, many developers still need to understand the importance of secure data storage.

Mobile app code and data should be stored locally, not in another web app. However, it is important to be careful how you store sensitive data to reduce security risks.

You can use encrypted containers or keychains to store data. In addition, you can add an auto-delete function to your data storage system so that data is automatically deleted after a certain period. The existence of a “leaking application” may disclose customer data or cause a data breach.

Earn Advanced Certification

Design your application to accept only alphanumeric passwords and make it necessary for users to change their passwords periodically. This ensures that your application has a vital authentication process that is a barrier to user-side hackers.

For sensitive applications like banking, you can add another layer of security with biometric authentication using a fingerprint or retinal scan, making it nearly impossible for hackers to gain access.

Provide fewer privilege 

The principle of least privilege is often critical to the security of application code. It’s better to grant access to the code only to those destined to have it than everyone should have the privilege of keeping it to a bare minimum.  

Have a solid API strategy.

Data APIs flow between applications, clouds, and different users and are the main conduit for content and data. Therefore, securing your APIs is critical to mobile and web application security.

Be careful if your application depends on someone else’s API for functionality. It means you trust your code to be safe. Make sure your application uses APIs that only provide access to the parts of your application that are needed to reduce security vulnerabilities.

‍

Require credentials before viewing sensitive information.

When asking users for credentials to access sensitive information or advanced content in your app, ask for a PIN/password/pattern or biometric credentials, such as facial or fingerprint recognition.

Provide support for your users.

As an application developer, you can do little to protect end users. Ultimately, your users must be vigilant and careful about protecting their online data and themselves. It would help if you strived to empower users by educating them on how to stay safe online.

With a strong mobile security strategy, you can quickly respond to threats and bugs; your apps will be safer for your users and ensure their future loyalty (and assets).

Stay informed and connected with your users.

Once your app is live and available for download, stay safe. Update security libraries, push updates to users, and use user feedback to help you find and fix security vulnerabilities.

Security Testing and Penetration Testing:

Extensive security testing, including vulnerability assessments and penetration testing, should be performed throughout the development lifecycle. This helps identify and fix security gaps before deploying the application, ensuring a strong defense against potential attacks.

Conclusion 

Developing a secure mobile application is just a matter of following security best practices in mobile application development. It helps prevent security breaches that could severely impact applications. Therefore, all business owners should start with robust code that follows expert coding practices and clear function calls. Additionally, if you implement the mobile application development security practices listed above, you will run successful business applications while keeping user data safe.
