8 Cool Tips to Enhance Your Mobile App Security

Mobiles enable us to do about everything on the web—from anyplace, whenever. We can do our banking work, track our wellness, control Internet of Things gadgets in our homes, shop, and also much more work remotely. Driving this mobile productivity are a huge number of versatile applications- software that interface with APIs and servers around the globe to deliver data, services, and, at last, value and convenience to users. But this all has to happen under a mask of  well- designed security or organizations hazard endangering their applications, their very own framework, their clients’ data, and their reputations. Because where digital activity increases, hackers are also there.

Applications and mobile devices are huge focuses for noxious action. Analysis of app security reported that 90% of apps had at least 2/10 of major security risks. Near about 50% of organizations have not designed any security towards mobile apps, a really enormous inconsistency when you consider the dangers of not securing a mobile application. 

What hackers does?

  • Infuse malware into apps and onto devices where it can access data, store keystrokes, and steal screen lock passcodes.
  • Duplicate your application’s code and also figure out a parody application containing malware.
  • Capture delicate data going over the wireless transmissions
  • Take client information for data fraud or extortion purposes
  • Get hold of protected innovation and private business resources
  • Access your IP or compromise your organization’s back-end network

Mobile applications and APIs that power them can possibly make frameworks and information defenseless on the off chance that they aren’t appropriately secured. Users expect applications to be secure and it very well may be anything but difficult to underestimate that trust. For the applications that deal with large amount of data like finance or healthcare, this is true.

What Can You Do To Secure Your Mobile App?

1. API Security-

Mobile applications interact with each other through API (Application Programming Interface). The APIs are vulnerable to attack by attackers. Hence it is necessary to secure them. To avoid such attacks, use authorized APIs in the app’s code. Every application must receive an API key to interact with the platform you are working on. Inserting an API gateway is another progression that designers pursue to increase security. Directing code surveys or including a firewall for web applications is another way to stay away from attacks by hackers.

Using API keys, you can build a safe and secure API. As a mobile app developer  you can analyze use and metrics with an API key. There is one advantage of using them is that- you can get built-in analytics. API keys are a necessity but they are not only the security measures. If keys to locks get lost or get stolen, a challenge may arise. This is where authentication makes that big appearance. With the use of tokens and 2 factor authentication, you can authorize apps to collect data.

2. Secure network connection-

Servers and cloud servers that an application’s APIs are getting to, ought to have safety measures set up to secure data and prevent unauthorized access. APIs should be verified to prevent eavesdropping on delicate data going from the customer back to the application’s server and database.


  • Containerization- It  is a method of creating encrypted containers for securely storing your data and documents.
  • Counsel a network security specialist to conduct penetration testing and vulnerability evaluations of your system to guarantee the correct information is ensured in the correct ways.

3. Secure Your App’s Code-

As a software project needed a security, mobile software also needs to be secured. Native apps are not the same as web applications, where data and software exist securely on a server and the client-side is an interface. With native apps, code dwells on the device once it is downloaded. This makes it more accessible to those with malicious aim. Numerous vulnerabilities can exist in an application’s source code, yet that is not where organizations focus their security spending. Network and data security components are are significant parts of the general security picture, yet security needs to begin with the application itself. Vulnerabilities can be brought about by developers’ mistake, inability to test the code, or your application may simply be focused on explicitly by a hacker.


  • Use encryption to protect the app. You need to keep the code secret and also difficult to read. Jumbling and minification are basic measures, yet they’re insufficient. Stick with moders and well-supported algorithms combined with API encryption.
  • Test code for vulnerabilities
  • Solidified, secure application code should be portable among devices and operating systems, and be anything but difficult to fix and update. You don’t need clients stuck without an update after a break, so make a code to be as agile as possible.
  • Consider the things like file size, runtime memory, performance and battery usage when adding security to app. You need it to be secure, yet not at the expense of execution and client experience.

4. Put Identification, Authentication, And Authorization Measures In Place-

Authentication and authorization help users demonstrate to an application who they are, adding another layer of security to the login procedure.


  • You should take extra caution if your app is depend on someone else’s API for functionality. Ensure that APIs that your app uses allows access to the parts of your app that are required to minimize vulnerability. 
  • OAuth2 has turned into the best quality level protocol for managing secure connections via user-specific, one time tokens.Installing this framework on your authorization server allow you to grant user permissions between the client and end users.
  • OpenID Connect is a protocol that allows users to reuse their same credentials with multiple domains with an ID token. So they don’t have a need to register and sign in at each point.

5. Implement A Good Mobile Encryption Policy-

As mentioned above, more of a mobile app’s code and data has to be stored on a device than with a traditional web app because you’re representing the varying performance, bandwidth, and quality of devices. If data stored locally on a device is more, then there will be more vulnerability. Defective apps can leak customer data without users knowing it.


  • File-level encryption protects data on a file-by-file basis. It is a way to encrypt at-rest data so it cannot be read if intercepted.
  • Encrypt mobile databases. 
  • Design apps so that very sensitive customer data like passwords, credit card data etc. stored directly on a device. Ensure that this data stored there is secure.

6. There’s no limit to testing your application-

Testing of an app includes examining the data security issues, session management with authentication and authorization. Create test cases according to threats and challenges.  These experiments should cover each OS version and phone models.

Tips to help in testing the security of your app:

  • Guarantee that all the application log documents don’t store the authentication tokens.
  • Check whether the drivers can see information according to their rights.
  • For web service, check the encryption of login authentication token.

There are many security testing tools to analyze the security of your mobile app. For eg., iPad File Explorer, QARK, Clang Static Analyzer, Smart Phone Dumb Apps.

7. Users: Protect Your Devices-

App developers can not do a great deal to guarantee clients have secure devices. But here are some points to follow for users to avoid security issues.


  • Try not to use a jailbroken or rooted device. This removes the security measures the device comes with and you’re left more vulnerable as a result.
  • Download applications only from trusted sources such as authorized app stores.

8. If You’re An Enterprise Organization With A Byod (Bring Your Own Device) Policy, Use Extra Caution-

For organizations that enable employees to utilize their very own devices, this can likewise open up the system to hacking vulnerabilities and make it harder for the IT office to manage access to information on their backend systems. These can give employees the comfort of working, yet additionally give organizations genuine feelings of serenity with regards to security.


  • Block unauthorized devices, and secure cleared devices with firewall, antivirus, and anti-spam software
  • Make devices “risk-aware” so that applications endeavoring to make certain transactions are hindered from doing so. Applications can be coded to distinguish and obstruct certain transactions from rooted devices.
  • Implement a VPN to create a secure connection.
