7 Tips for Secure App Development

Building a mobile app that will deal with online transactions and personal data of users? Here are top 5 tips from the best mobile app development company in Dubai that will ensure your app development process is secure and you come up with a bug free, protected app code.

1. Data Encryption

Utilize encryption algorithms to secure sensitive data stored on the device (such as user credentials, payment information, and personal data) and transmitted over networks. For advanced applications, you’ll have to implement strong encryption standards like AES (Advanced Encryption Standard) to protect data, both at rest and in transit.

2. Secure Authentication

Ask your development team to implement secure authentication mechanisms to verify user identities and prevent unauthorized access to the app.

Add user-side security features like strong password policies, multi-factor authentication (MFA), biometric authentication (such as fingerprint or face recognition), and OAuth/OpenID Connect for secure authentication and authorization.

3. Secure Network Communication

Ensure that network communication between the app and backend servers is encrypted using HTTPS (HTTP over SSL/TLS) to protect against eavesdropping and man-in-the-middle attacks.

4. Secure Code Practices

Ask your app development team to adhere to secure coding practices to mitigate common security vulnerabilities such as injection attacks (e.g., SQL injection, XSS), buffer overflows, and insecure data storage.

5. Secure Data Storage

Implement secure storage mechanisms to protect sensitive data stored on the device, such as using the Android Keystore or iOS Keychain for storing cryptographic keys.

6.   Secure User Input and Output

When building data input features, use secure APIs for handling user input, and avoid using insecure functions or APIs that may be susceptible to exploits.

7. App Permissions and Access Controls

To protect data on user devices and smartphones, implement fine-grained permissions and access controls to restrict access to sensitive app functionalities and data. For default settings, follow the principle of least privilege, granting only the necessary permissions required for app functionality.
