How to Ensure Mobile App Security: Key Risks & Top Practices

by Anastasiia Lastovetska

Application security today is not just a desirable feature; it is a necessity. Mistake insecurity – and you will lose all customers, trust, and your income. Therefore, today, mobile app developers prioritize security as soon as they start working on it.

Statista shows that Internet users are most afraid that their personal data will be leaked to fraudsters.

When fraudsters use your address, bank account numbers, family members’ names at stake, your customers will not trust you if you cannot protect this data.

1. Unsecured Wi-Fi

Many Internet users often do not think that they can use unsecured Wi-Fi networks. As a result, unsecured Wi-Fi can be used by fraudsters to steal personal data.

2. Applications with malicious code

When users download an application from outside the App Store and Google Play, there is a risk that such applications will be without proper certification, and it is easy for hackers to get your data through such applications.

3. Data leaks

Suppose the company that developed the application does not take advantage of additional measures to protect their applications in the cloud. In that case, hackers can quickly get into the remote access servers and steal the data stored there.

4. Insecure authorization and authentication

You can ignore this point, but simple passwords and optional two-way authentication put your users’ data at risk. This approach creates loopholes and vulnerability threats that cybercriminals can investigate.

Let’s now consider:

How can you protect your mobile app?

There are ways to help make your application more secure.

1. Turn on strong authentication

Multifactor authentication is by far the best way to protect against password guessing and hacking.

2. Encrypt mobile communications

You must encrypt your message between the server and the mobile app. In this case, data that is stored locally must also be secured with a cipher.

3. Protect apps from theft

When you store your users’ data on a local drive, it can be a serious risk of data falling into the wrong hands. Plus, you have to be sure that you can remotely erase important information if the device is lost or stolen.

4. Secure data in the cache

Any software development company, such as MLSDev, knows that data from the cache is very quickly vulnerable and is an attractive target for hackers. Therefore, they try to reduce this risk using passwords and automatic erasure of data from the cache.

5. Upload apps only from trusted stores

And at the same time, warn your users that if they download an application, not from the list of safe stores, they put their data at risk.

6. Don’t save passwords locally

Storing passwords in this way is very dangerous. You simply cannot do anything if the device on which you store important passwords is stolen. It is good to use data from social networks for login; it is a reliable way to protect user data leakage.

7. Use the services of mobile application security

There are specific tools that improve the security of your application—for example, Lookout for Android, AVG Antivirus Free, Norton Mobile Security, and others.


Keeping application security is not an easy task. At the same time, without this step, you shouldn’t even start developing mobile applications. Forbes has released an article that says that neglecting security while building a mobile app will lead to bankruptcy and loss of reputation. Considering this, both the development companies and the users themselves mustn’t neglect security measures by using.

The security of mobile applications does not depend solely on software vendors. End users should also take all necessary precautions, such as using only strong and unique passwords and installing applications only from trusted sources.
