In 2020, people are excessively accessing their smartphones. Right from online banking, chatting, shopping to handling your online businesses, people these days are not only greatly depending on the mobile apps but also keeping sensitive data in mobile phones.
According to analytics, 57% of the digital media time is spent on using smartphones and tablets.
Did you know:
- Mobile apps were downloaded for over 204 billion times in 2019 and with the increasing usage of applications, it is for sure that figures must be jumped to the next level in the coming years.
- The forecast from Juniper Research report reveals that approx 2 million people that is around 40% of the world’s adult population, are approaching online banking apps.
With the increasing usage of mobile apps these days, app security has become one of the serious issues for developers and users.
No matter whether you are an iOS or an Android user, applications tend to contain critical vulnerabilities on both platforms.
Just have an idea with the below image:
So in this post, we will discuss how to increase the security of the Flutter based applications and minimize the risk of vulnerabilities in the application…Why it is important to hire flutter developer and what are the benefits of choosing Flutter for mobile app development.
However, before jumping on the tips to increase the security of the Flutter based applications, we need to understand “what are the common vulnerabilities and security issues arises in the mobile app?”.
5 Biggest App Security Risks and Solutions That App Owners Should Aware of in 2020
According to the Gartner Reports, 75% of the mobile apps fail to clear mobile security tests that ultimately put your sensitive data and documents at high risk.
So here are the common security risks that every app owner should take it seriously:
1. Unauthorized Access To Your App
Providing access to the app without verifying the user’s authentication is the biggest security risk. So the app must be ensuring that the user should be a true user and should temporarily lock the access in case of multiple failed login attempts.
Solution: Flutter always puts the app security at the top list, therefore, providing developers with the security and authentication plugins. By integrating this sign-in plugin to your app, you can easily add a user authentication verify check to your app. Also, you can ask any app development company for a better solution with the official plugins.
Pro Tip: To enhance the security of your app, always integrate official security plugins of Flutter instead of handling app verification yourself. For instance, you can integrate Google sign-in plugin for Google Authentication.
2. Leaking of Sensitive Data
These days, with the excessive usage of the mobile phone, your mobile apps have all the sensitive data right from your user IDs, password, PIN, financial details, personal details, and more. Your sensitive data can be easily compromised if the app security controls fail to be implemented rightly in the app. The weak app security can allow unauthorized parties to access all the information on your app.
Flutter provides a secure data storage plugin for both the leading operating systems with the name of NSUserDefault for iOS and SharedPreferences for Android. These plugins provide a secure storage facility but it is recommended to avoid storing your sensitive data including passwords and PIN numbers.
Pro Tip: Like most mobile apps, is your mobile app also using in-memory cache to provide quick access by directly fetching the data from the stored memory? If yes, then you need to think twice, that is why you are keeping all the data on the mobile all the time. You should consider the core security principles that ask you to only keep the data that you often need. To keep your data safe, it is worth setting up a periodic time for automatically cleaning the data cache that has been expired.
When using a Flutter based app, it always provides the information when you are about to switch to background mode. You can access the information to set up a timer for regular clean-ups of the cache with the permission of the user.
3. Session ID Attacks by the Unauthorised User
Either intentionally or unintentionally, sometimes anyone can try to steal the sensitive information of your phone or may even try to steal the identity of the valid user. For example, you lend your phone to your friend for playing games or allow any guest at your home to access your phone, they can try to access the information that you want to keep it private from them.
Or sometimes, any colleague can intentionally try to access your corporate email to steal important information. The best way to protect information is to integrate some unpredictable passwords or locks to your phone that can’t be cracked by unauthorized users.
Despite using the device-level security (Unlock Screen), it is important to integrate app-level authentication to keep the sensitive data remain private and secure in the app. In fact, app-level authentication can add an additional layer of protection to mobile content. Therefore, Flutter provides special authentication plugins like TouchID for iOS and FP Sensor for Android apps to uplift the app security.
Pro Tip: Since numerical or alphabetical passwords are predictable, therefore it is advised to use only officially approved fingerprint or touch ID locks. Moreover, it adds more convenience to access it multiple times and secures your data from malicious users.
4. Code Injections Via Malicious User
Code injections are one of the most common practices by the attackers that access the database of your app and insert the unauthorized codes into the existing coding. Injecting unwanted codes can result in major issues like data loss or corruption, a total takeover of the app, or denial of access as well. The scariest thing about it is, that this type of attack isn’t so hard to execute.
Developers can easily increase the security of the Flutters apps as all the plugins come up with the required permissions that are already baked into the plugin code. So if you are integrating officially approved plugins in the app, you don’t need to further add additional codes for unauthorized code injection. Moreover, it is advised to hire a software development company for quick assistance.
Pro Tip: In case your app has native codes, then it is required to add additional permissions to your app to avoid putting the sensitive data at risk.
5. Securing The Smaller App Window
It’s common to switch to another task by accessing the smaller windows of the app. But unfortunately, the smaller windows of your app can still show the content to the user in the minimized window. The malicious user can easily get the information from this small screen despite having your app protected from the additional measures such as Touch IDs or face scanning. Flutter app development companies can easily understand the pain of the users and implement such strategies to secure your app from malicious users.
Flutter is not providing any official plugin to secure your app window as the implementation process is depending on the native APIs and application life cycles. However, still, there is a hope to enhance its security of your app. Hire a Flutter developer as Flutter provides detailed instructions to secure your app window for both OS.
While Android natively supports a wide range of window modes, therefore, it is a good way to use the WindowManager flag within the MainAcitiving of the Flutter app to disable the screenshots of the specific screens.
Pro Tip: Managing the app screenshots on your Flutter App is not as simple as there are no official plugins to integrate into your app. You need to carefully execute the instructions given by Flutter, so it is worth looking for expert mobile app development solutions to secure your app window.
Why Flutter Has Become a Popular Choice for App Development?
Despite being a newbie, Flutter has already won the heart of many developers and became a hot topic of the town. Afterall, Flutter is a baby of Google and based on Google’s in-house language that is “DART”. Apart, Google’s Flutter provides you an advanced software development kit (SDK) with a framework, widgets, and tools that ease the app development process and allows developers to expedite the procedure.
Here are the reasons why startups are considering Flutter for mobile app development:
– Single Codebase For Both Platforms
Being a bootstrapper, one of the major concerns for you is the budget. However when hiring a mobile app developer to customize your first app with Flutter framework, then startups can take the benefit to launch their mobile app on both major Operating Systems (Android and iOS) by simply leveraging the single codebase of Flutter.
Since Flutter doesn’t depend on the platform and has its own design and widgets, therefore, it is possible for developers to build two apps with different designs by using the one codebase. It ultimately saves a great amount of time and cost.
– Faster Coding with Hot Reloading
When you hire a mobile app development company for the Flutter based app development, then you can expect a faster and more dynamic app development solutions.
Flutter is the standalone framework that offers you a hot reload feature, which means a developer can make instant changes in the app coding without even saving the file. Hot Reload feature actually speeds the development process as each change usually takes about milliseconds to fix the error and allow developers to try anything faster in the coding.
– App Testing Can Be Faster With Flutter
Developing an app for two platforms means you need to devote a long time for the testing. However, with Futter, the quality assurance process can be faster as both the apps are based on one single code. What’s more, the quality assurance engineer has less work to do as they need to check one app only. But, they check the app on both platforms in case if there is any difference in design or functionality.
– No Licence Fees
Flutter is free and open-source platforms that allow developers to build highly-interactive applications that give a native feel although in real-time.
– Customize The App With Best Design
Since Flutter is launched with a highly flexible and scalable library of widgets, therefore, developing and customizing an app with a tailored interface and engaging themes are quite easier with Flutter. Developers can design their Flutter app in a way that their users love to access it.
– Build the Same UI for the Old Devices
Your new Flutter app can look the same on old versions of Android and iOS devices. So no matter, whether you are targeting newer versions of devices or older, you can develop a flutter app that supports both newer and older devices with no additional cost.
Additional Noteworthy Features of Flutter Framework
- Flutter is known for its productivity as it has a portable GPU rendering UI that provides access to work on multiple up-to-date interfaces.
- Flutter apps are easy to localize and businesses to leverage a wider global user base.
- This framework provides complete support for a wide range of IDEs including Xcode, Android studio, Visual studio code, and more.
- Flutter is well equipped with native ARM code which makes it more compatible with developing enterprise-level apps.
In the Nutshell:
The noticeable features of the Flutter are clearly making it a dominant framework over other cross-platform frameworks and allow more and more startups to opt for mobile app development. The detailed list of features is only making Flutter a more popular and powerful framework over others, but still, you need to integrate appropriate plugins to strengthen the security of the app.
Now the central question is “how to implement all the security plugins to your flutter based app”?
Hire a Flutter Mobile App Development Company
If you are the one who has been investing in a cross-platform application and choosing a flutter framework for the development and concerned about the security of the app, then it is worth hiring a flutter app development company. The reason being, they are backed by highly specialized developers with the knowledge of the right plugins and understand the importance of integrating officially approved plugins to the app to avoid compromising the security of the DATA.
The best part about partnering with the best app development company is, they follow the proper hierarchy of the app development process and always ensure you the best product quality by keeping in mind the security of the app.
No matter how complex your app is and what framework you have chosen to develop an application, security is the major concern for any developer. So it is worth to spare some time reading all about common yet major security risks of applications and how you can address it with official flutter plugins.
Since the usage of the app will continue to increase and threats of the app will also rise, but being a developer- it’s your responsibility to ensure peace of mind to the user by simply increasing the security of the app and making sure that information will remain safe.
Failing to app security tests can impose a negative impact on companies and users will immediately switch to the app of competitors. To avoid such consequences, it is worth collaborating with the flutter app development company to develop your app with tighter security.
