Top Practices You Need to Develop Secure Mobile Apps

Many businesses have found mobile apps to be one of their most important revenue generators. Their revenue was close to $693 million in 2021 and is expected to rise to $935 billion by 2023.

 Unfortunately, this incredible growth comes at the cost of cyberattacks. Mobile app security is, therefore, so important.

 There are many concerns about the security of user data and businesses that interact with brands for different reasons. 

These users exchange data on apps with brands, which can lead to malicious exposure if security measures are not in place.

It would help if you took reliable security measures to protect your customers and avoid data breaches. Here are some best practices to protect your mobile app.

  • Encryption of Source Code

Mobile malware can track bugs and vulnerabilities in the source code and design native mobile apps since most of the code is on the client side. Repackaging renowned apps into rogue apps is a common tactic used by attackers. 

They then upload the apps to third-party app stores to attract unsuspecting users.

These threats can damage your reputation. Developers need to be cautious when building apps. 

Make sure you include tools that can detect and address security flaws. It will make your application unreadable and protect you from potential attacks.

  • Penetration Testing – Conduct a thorough QA & Security check

Before you deploy your application, it is a good idea to test it against random security scenarios. Pen testing is a great way to avoid vulnerabilities and security risks for your mobile apps. It is essential to detect loopholes in the system. These loopholes could become potential threats to your mobile data and other features.

  • Encrypt All Data

Each unit of data exchanged via your app must be encrypted. Encryption encrypts plain text to make it a vague alphabet soup with no meaning for anyone but those with the key. So even if data is stolen or misused, nothing can be read and used by criminals. It is easy to see the power of encryption when agencies like the FBI or NSA ask for permission to decode WhatsApp messages and access iPhones. Hackers can’t do it if they don’t have the will to.

  • Libraries: Be Extra Cautious

Be doubly cautious when using third-party libraries. First, before you use it in your application, test it thoroughly. Some libraries are extremely dangerous for your app, despite being very useful. To protect their apps against vulnerabilities in libraries, developers should use internal repositories that are controlled and have policy controls during acquisition.

  • Your App Should Know Less Than You Do

According to the principle of least privilege, an app should only request data it is absolutely required. If you don’t need access to your messages, don’t ask your app for them. Limit your access to the essentials.

  • Continuous App Testing and Regular Updates

No platform guarantees 100% security. Even if you carefully scrutinize every stage of the process, there will always be dark spots. Therefore, developers should not stop app testing. You can also create your bug bounty program if you have the funds.

  • Compliance & Integrity

Every mobile app must meet specific security requirements before it can be launched. In addition, developers may need to follow certain security precautions as per the directions of the app store. These security measures can be used to download and install an app.

It ensures that a platform distributes only approved applications.

Developers can submit apps to the store. Once submitted, their identities, as well as the application’s security requirements, will be validated. Then, the application will be available for download if everything conforms to the operating systems guidelines.

Although this might seem overwhelming, many coding sign options on the market make it easy. You can also quickly obtain a cheap code signing certificate to protect your application’s integrity and compliance. It is a valid publisher certificate that proves the code was not altered since its creation.

Developers can use this certificate to encrypt their identity information, which is then decrypted using a public key that is available to them. The API, or Application Programming Interface, is another aspect of app security that you should be aware of.

Reduce the Storage of Sensitive Data

Developers prefer to store sensitive data in the device’s local memory to protect users’ data. However, it is best not to store sensitive data, as it could increase security risks. You have two options: keep the data in encrypted containers or key chains, but if you don’t have any other choice, it is best to do so. You can also reduce the log by using the auto-delete option, which deletes data automatically after a set time.

With the growing risk of malicious activity, mobile app security has become a top concern for developers. Users are less likely to trust unreliable apps. The above best practices will answer your concerns about creating a secure mobile application by the top mobile app development company in South Africa for your customers.

  • Use High-Level Authentication

It is essential to use more secure authentication, as weak authentication has been linked to some of the most severe security breaches. Put authentication is passwords and other personal identifications that prevent entry. 

Although authentication depends on the end users, developers can help them be more cautious about authenticating. Your apps can be configured to accept strong alphanumeric passwords, which must be renewed every three to six months. 

Multi-factor authentication, which combines a static password with dynamic OTP, is becoming more popular. Biometric authentication, such as fingerprints and retina scans, can also be used for susceptible apps.

  • Install Tamper-Detection Technologies

There are several ways to send alerts to your code when it is being tampered with or injected malicious code. To ensure that code isn’t altered, active tamper detection may be used.


Mobile applications are in high demand due to the rapid growth of mobile usage. It is the developers’ job to create applications that meet users’ expectations and needs. Unfortunately, mobile apps are not exempted from online attacks.

Recent security threats to mobile apps have increased. Unfortunately, these threats have increased in recent years. As a result, developers now must ensure that their apps are safe. This blog explains the best practices for protecting mobile apps.
