Android, a Linux based open source mobile operating system from Google, has absolutely transformed the mobile world today. The statistics reveal that the sale of Android based phones is much higher than that of iOS, and so is the user demand for their app development. As a consequence, android app development markets worldwide are flourishing at prolific rates.
No matter how much is the demand, accomplishing the same is a process not always as simple as it sounds. Although, the SDK for Android OS is available free, but its app development process can take you a long way around. With an array of Android based devices and distinct flavors of its OS releases, the security of Android devices can largely be a concern.
So, here we will determine what all can be done to implement the security features to ensure the safeness, as well as improvise the quality of the Android apps in your organization.
- Be Cautious of What all the App Stores in the Device: You should be careful of what all the application stores on the mobile device, which includes parameters like what is cached and logged, as well as what is stored within the structured data. Common vulnerabilities include unsafe storage of user credentials, and sometimes even the passwords within the structured data storage system or the system cache.
- Use Encrypted Communication: It is advisable to communicate with the backend application server in an encrypted format. Use of certificate pining is a good example of enhanced security and best practices, as it is becoming a new trend in mobile app development.
- Don’t Trust Upon any user Input with Web Applications: As with web apps, all user input should be treated as un-trusted with Android applications as well. Various issues involving cross-side scripting (XSS), SQL, JSON/ XML and OS command injections, need to be handled by both the client and the backend app server. Therefore, it is recommended to avoid using classes with known vulnerabilities in the code.
- Refrain Storing any Sensitive Data: Avoid storage of sensitive information as much as possible for your Android device, especially during the run time. Doing this will discourage the hackers and prevent them from erring with your mobile app. The whole idea behind this is data processing, when need be and delete the same as soon as the requirement ends. Data, not required, should be encrypted.
- Go through Perplexity: It is very important that your Android apps face the obfuscation process. This should be done to encrypt the key that has been used in the encryption. A good approach would be to refrain from downloading the encryption key from the server, during the run time.
- Avoid Redundant Permissions: Excessive permissions should be avoided for Android apps. Try to edit only the most urgent ones. It should be a strict “NO” to use permissions that access personal information, in order to avoid anything from going wrong in case of a data violation.
Concluding the discussion to our security tips for Android Application Development, remember that is essential to incorporate an efficient app development life cycle having multiple protection layers. Also, endeavor to access your mobile with a strict security checklist. This can help identify vulnerabilities present within your Android app.
