8 simple steps to improve your mobile app security

In today’s technology world, data breaches and cybersecurity threats are very frequent. The problem is most people don’t even think about mobile app security. As a business person, your top priority should be to ensure your app’s security.

There are many types of mobile app security issues that can occur. Some of them are as under:

  • Unintended data leakage
  • Poor authentication
  • Improper session handling
  • Broken cryptography

The good news is app makers can take few steps and solve the app security issues. You can follow the given best practices for app security and stay ahead in the game. These practices will help you secure your mobile apps for better end user experience.

1. Secure the backend

Your backend servers should have security measures to safeguard against malicious attacks. Make sure that all the APIs are verified based on the mobile platform you intend to code for. Remember, transport mechanisms and API authentication can differ from platform to platform. Consider federation as it is a next-level security measure. It spreads resources out across servers. They are not all in one place and separates key resources from users.

2. Use high-level authentication

Security breaches occur due to weak authentication. You should add multi-layered authentication process and create a strong password for each layer. You can design your app that only accepts strong alphanumeric passwords. Those passwords can be renewed every six months. Dual-factor authentication is a good way. In this way, the user will be required to input a code sent to his or her texts or email upon logging in. multi-factor authentication feature like one-time passwords or fingerprints can be used.

3. Enhance server-side control

In the case of poor server-side controls, one cannot protect the mobile app and confidential data. Hackers simply crack the data-driven applications and hack the servers by sending inputs through the fields of the apps.

Poorly secured back-end APIs and platforms can easily get affected by vulnerabilities. Make sure you don’t have weak user-side controls.

4. End-to-end encryption

Payment cards, merchants, card brands and issuing bank play a vital role in an online transaction. Loads of sensitive data is worth billions of dollars. It has become a hotspot for hackers.

End-to-end encryption ensures that data is safe and sound. It conducts security edits audits and penetration tests. End-to-end encryption takes the security measures to an extra mile. You can use file-level encryption. It protects data on the file-by-file basis.

5. Offer real-time text and email alerts

Most of the users use mobile banking on their smartphones. Users have direct access to their email or text messages. Banks can send a quick, real-time email or text alert to notify a customer of account activity.  This way fraud can be prevented.

Banks application allows you to be notified if more than a customer-specified amount of money is spent. Users would likely to be aware of a large amount of money being spent from their account. For your app security, you can follow such practices as well.

6. Test, test & test

Many developers don’t test their code. QA is a vital part of building quality code. Experts should test for functionality, usability, and security. Native, hybrid or web – whatever your app type is – testing is a must. At the testing stage, you will be able to detect vulnerabilities in the code. You can correct them and publish your app.

One time testing is not enough. Your QA team should review the code regularly. They should identify security loopholes to stop data breaches. You can use emulators which lets you test how an app will perform in a simulated environment.

7. Data storage

Data loss can lead to misuse of the data. In case, developers store the data on the client side mobile device and device get stolen then it’s a data loss for both. Users tend to forget factory reset setting when they sell their phone at the online marketplace.

This way the buyer get the access to seller’s personal data. To prevent this, keep the professional and personal data in a secure place using strong password protection. Keep in mind the users’ external and internal storage security.

8. Be careful with API

API – application programming interface is a vital part of backend development. It allows applications to talk to each other. They can create some security headaches. You can incorporate an API gateway to tighten mobile app security. Each application should receive permission key before they interact or make changes on the platform.

Final words

Mobile apps have made our life easier. There is a risk of hackers compromising the data resulting in a huge chaos situation. It is crucial to implement online security measures with the utmost care. We hope that above-mentioned practices will be useful for you. Make sure your app is safer for users and ensure loyalty for the future.
