Top 5 Mobile App Security Best Practices for Developers

In today’s world of smartphones, tablets, and other mobile devices, it’s more important than ever for developers to keep their apps up to date with the latest security features. Here are five of the best practices that all app developers should follow when building a mobile app.

  1. Encrypt all data

When data is encrypted, it is converted into an unreadable format that can only be accessed with a special key. It’s a must for any application that stores sensitive user information such as passwords or credit card numbers.

There are many types of encryption algorithms, and the safest are those that use a combination of two or more methods. When selecting an encryption algorithm, be sure to consult with a security expert to ensure you are using the correct one for your application.

There are many libraries that can help you encrypt your data, such as AESCrypt from Android and CommonCrypto from iOS. If you are unfamiliar with encryption algorithms, do not attempt to implement your own.

  1. APIs and secure web services

In order to communicate with backend servers or other third-party services, your application will need to secure an API (Application Programming Interface). the API Security must be top notch and must be secure and properly authenticated so that no unauthorized access can take place.

One way to make sure your API is secure is to use TLS/SSL encryption. This encrypts the data that is sent between your app and the server, ensuring that no one can eavesdrop on the transmission.

Another way to secure your API is to use OAuth authentication. This standard allows users to authorize an application to access their personal information without having to share their username and password with the developer. If you’re unsure how to secure your API, consult a security expert or use one of the many available API libraries designed to help you.

  1. Deploy appropriate session management

When a user is logged into your application, you must ensure that their session remains active until they log out. If the user’s session expires, he will have to log in again and this can be annoying for him.

One way to keep a user’s session active is to use cookies. These small files are stored on the user’s device and contain their authentication information. If the user closes your app or stops using it, you can send them a new cookie that will keep them logged in until they choose to log out.

If cookies are not an option for your mobile application, for example, if you are creating a game, be sure to use secure storage when saving session data. That way, if the user’s phone is compromised, you’ll be safe and their session information won’t be accessible without first knowing their login credentials.

The last thing to mention about sessions is that they should never expire. If a user does not use your application for an extended period, such as 30 days, make sure to automatically log them out. This will protect their data and prevent anyone from using their account without permission.

If you don’t know how to manage sessions in your application, there are many libraries that can help you. The most popular are SessionStorage for Android and NSURLSession for iOS.

  1. Use high-level authentication methods

When users sign in to your app, they shouldn’t be prompted for their username and password every time. This can be a pain for the user and also opens up the possibility of someone stealing their login credentials.

Instead, use high-level authentication methods such as OAuth or Facebook Login. These methods allow the user to authorize your application once and then be automatically logged in on all subsequent visits.

Another high-level authentication method worth mentioning is Touch ID/FaceID, which allows users to securely authenticate with their fingerprint or face respectively. This eliminates the need for passwords while ensuring that only authorized users can access your application.

  1. Use only authorized APIs

If your app requests permission to access certain APIs, be sure to only allow it to do so when the user is authenticated. This will prevent attackers from executing sensitive API calls on their behalf and can help protect against data theft or other unauthorized actions.

For example, if an attacker finds a way to view users’ credit card numbers stored on their devices, your app will be responsible for that data leak. That’s why it’s important to only allow certain endpoints to run when the user has successfully logged in and passed authentication checks.

There is no doubt that security breaches have become common in the cyber world and the stakes are higher than ever. Consumers place great trust in your business when they download your app to their phone or tablet. So you need to make sure they can feel safe. Following these best practices for mobile app security is essential to protect your users’ data.
