Earlier in this chapter, while discussing application vulnerabilities and different phishing attempts, we discussed some of the best practices for ensuring mobile security. Let’s take all of the information from above and organize it into a few more helpful guidelines to assist you in keeping mobile applications secure.

A portion of the application is sent to the server.

By transferring part of the program logic and algorithms to the server, it is possible to improve the security of mobile apps. Cracking a server that has been properly set up and dependably protected would be a strenuous effort to do.

Maintain the confidentiality of your code.

However, the public version of the mobile software would allow a fraudster to access your code and steal your identity. So, first and foremost, be certain that he will get nothing from it. To accomplish the aim, you must ensure that the app code is protected to the greatest extent feasible.

It should be concise and powerful, and it should be built on the most up-to-date algorithms. Also, make certain that it is thoroughly checked regularly, rather than just once. Remember that even the slightest programming flaws and defects might result in an application being cracked.

Consider the concept of user code protection.

If a user code is entered more than once, the program should immediately log out or possibly be banned after a certain number of failed attempts are made.

Make use of cutting-edge encryption methods.

We’ve spoken about the necessity of data encryption and how it may help protect your information. As a result, you understand the need to store and process sensitive user data in an encrypted format. Additionally, it would be wise of you to contact mobile app security specialists to determine whether or not the encryption techniques you’re utilizing are very effective.

Make assured that the appropriate authentication method is being used.

It would be beneficial if you provided multi-factor authentication to protect user accounting data adequately. When it comes to security, multi-factor authentication is a multi-step verification approach that relies on many levels of protection.

Double-checking the username and password, sending an SMS with a secret code, and other measures may be necessary. Precautions of this kind are especially important for financial institutions and law enforcement agencies.

API keys should only be utilized with extreme care.

API keys are known to authenticate user connections, mentioned in the API documentation. We ensure that they are not kept in a public or easily accessible position if this is the case.

When utilizing third-party libraries, it is important to exercise caution:

Please make no mistake about it: open-source services and technology should not be relied upon completely. Excluding such solutions are time-tested solutions that have been used by large organizations for a long time and have shown to be beneficial. Take, for example, the Realm database, which has built-in encryption to keep its data secure.

Relying on the aid of closed-source libraries, on the other hand, is also unjustifiably restricting. It’s very unsafe since you won’t be able to analyze the quality of the code or the effectiveness of the mobile security solution you’ve chosen.

Hack detection technologies should be used.

We’re talking about strategies that will allow you to set up an alerting system if a cracking attempt is successful here. Moreover, if you discover that the app code has been illegally amended or modified without authorization, you may prevent it from working by forcing it to stop operating.

Don’t underestimate the significance of taking simple measures.

On-device software on smartphones should not be authorized to display sensitive user data in large, brilliant type on the device’s screen. Even though the advice seems very simple, it is really important.

The application is being updated and tested regularly.

As surprising as it may seem, building an application and then abandoning it in its present condition is not an option in this case. More and more sophisticated cyberattack tactics are being developed with each passing year, and you must be prepared to deal with these new and evolving dangers. Therefore, the only alternative left to you is continuous updating, accompanied by testing.


It would be beneficial to now comprehend why it is vital to set aside funds to protect mobile apps. As opposed to what could seem at first glance, we are talking about a contribution to future success and the prevention of possible financial and reputational harm, rather than an extra spend of money.

Our professionals take the protection of mobile viruses and other vulnerabilities are thus taken extremely seriously. We design and create applications and websites that are safe to use and navigate.
