Android rules the smartphone operating system market.
Android operating system is developed with the flexible security controls that ease android app development for developers.
Nonetheless, Android has multi-layer protection to deliver security protection for all users.
Android apps are using both advanced hardware and software, and local and served data to deliver value to the users. In order to protect the value, the platform offers an app environment that makes sure security of a device, network, app, and user.
However, to add more security in android apps, we have some security tips for Android app development that developers can use anytime, as security should be at the top of their priority list.
1) Validate the Input Fields
Android developers shouldn’t predict the threats that happen from the client side injection.
An android application that accepts input is an important factor as any malicious code, which is passed through a text field as input to the apps, can interrupt its full-functioning.
Thus, while going for Android app development, it is necessary for the programmers to have a security testing checklist to validate all the input fields.
DEP and ASLR are some technologies that reduce the impact of such issues on the developed apps.
We recommend minimizing the number of permissions that your app requests. The risk of misuse is reduced by not having access to sensitive permissions. It can also enhance user adoption and make an android app that is less susceptible for attackers.
3)Use encrypted communication
It is advisable to use encrypted communication with the backend application server for SSL/TLS use.
As 1024-bit key length is the weaker method of encryption, all the certificates must have a 2048-bit key length. Currently, ‘Certificate Pinning’ is a trendy practice in mobile application development.
4)Always use HTTPS and SSLSocket
Usually, HTTPS should always be used to handle sensitive data like external IOT device commands or personal user data.
There are many mobile users that connect many different public Wi-Fi hotspots that might have rogue individuals with IP packet sniffers like Wireshark. If you are downloading anything through HTTP connections, it should be approached cautiously, as it could have been changed.
This is the primary reason why SSLSockets is good as compared to standard sockets. They give authentication with the end point and encryption of data by using the transport protocol.
Android app developers can check and verify the server’s certificate that they are trying to connect against a hash of what it should be. This prevents DNS alteration attacks, where someone routes traffic to a dummy site on a public access point.
It is possible that data from the application servers can be hacked.
Do you know how can the responses between the app and server be altered? The reason is most of the Android apps are based on APIs like SOAP API and REST. For this approach, just an API requester will suit.
So, when you start android app development process, it is advisable to use secure coding practices at the server end.
