Checklist for Creating Secure Mobile Apps

Today, there are around 3.5 million mobile apps available for download on Google Play. The Apple App Store has 2.22 million. And you know what, many of them have failed badly to get any attention or fulfill the objective they are designed for.

The thing is, every industry is saturated with thousands of mobile apps, designed for the same purpose. If you are launching a mobile app for your delivery services, online ticket booking, or perhaps your android game, why should people choose your app?

The thing is, the expectations are high these days. People expect mobile apps to be perfect by all means. A small bug that didn’t mean much in the early days can be the difference between your success and failure on the app store.

One of the areas of mobile app development taken seriously is mobile apps’ security. Everybody is creating apps but not all of them are secure. And if you have failed to convince people that your app is secure, they are never going to download it.

So, how do you create secure mobile apps? As a renowned mobile app development Dubai, we follow this checklist to ensure 100% app safety:

1. A Secure Source Code

A secure code is the first thing you need to ensure in the app development process. Leaving the source code open entails the risk of a security breach since it’s exposed on the client-side.

This is an important aspect of app security since enterprise apps can contain as much as 90% open source codes. And you can’t leave out these, this source code can reduce your workload and fasten up the development process.

To overcome this issue, you can obfuscate the code. This way, you will get rid of low and mid-tier troublemakers.

Also, you can use the new and protected codes to overcome this vulnerability. Besides that, rigorous testing must be done before deploying the app so any such security threat can be avoided to a great extent.

Evaluating the source code and securing it would be really useful in this regard. It may take some time but saves you from a huge mess in the future.

2.Minimum Permissions & App Requests

Well, it’s normal for mobile apps to take permission from the user to access a certain feature, for example, a camera or your sensitive data. Though it seems a good practice, in the long run it can have an adverse effect on your app’s security.

The thing is, in some cases, the system grants some permissions automatically. And this is where a security breach can occur. So the best practice is to keep the number of permission app requests to a minimum during the development process.

3. Secured Network Transactions

Another thing to consider is network transactions. The risk of data theft is great during these. Be diligent in this regard, follow best practices like telephone networking, IP networking, and handling of the user data to make these 100% secure.

4. Increased Data Portability

Data portability is a great feature to use in your apps to boost security. The thing is, a huge amount of data is wasted when it is confined to a single platform or service. With data portability, you can make your app secure and even fix bugs with ease.

When a user is able to sign in and automatically share his credentials on different platforms, there are fewer chances of data theft. At the same time, it will make it easier for the user to access other apps on the go — this feature is particularly great for social media apps.

5. Don’t Keep Sensitive Information in the External Storage

Data stored internally is less vulnerable to theft. However, the data created and stored externally entails a risk of loss. For example, data stored in an SD card is writable and readable.

So make sure your app doesn’t have to access any kind of data from outside. And if it has to, in any case, the data should be cryptographically verified.

6. Authentication & Authorization Systems

And of course, there should be a strong authentication and authorization system placed in the application for enhanced security. There are numerous ways to invade the app and manipulate data. 

It’s the developer’s job to add ways to validate and authenticate that data. In fact, it’s recommended to add a multiple-factor authentication system or multi-step authentication system to add another layer of app security.

7. Data Wiping & Device Locking 

Nowadays hackers have new ways to steal your data, so developers have to be extra cautious. During the app development process, make sure the user-level application policies are clearly defined. 

This includes wiping the app data once a user has failed to input the correct credentials multiple times. Likewise, you can restrict sequential numbers to be used in the password, mandatory use of special characters, etc.

With these restrictions, you can keep the user data secure.
