Best Practices For Your Mobile App Security in 2024

Best Practices For Your Mobile App Security in 2024

Did you know that global phone usage has increased to 7.07 billion?

With each day, our lives are becoming more and more reliant on mobile apps, which is raising security concerns. That’s why we need to understand the possible risks and protect our data.

By 2024, the number of online shoppers is at 2.71 billion. As the number of online shoppers is significantly increasing, there is a need to keep mobile apps secure. Unfortunately, mobile phones do not come with antivirus and users need to keep the app updated. Likewise, mobile app developers should also take appropriate steps to prevent hacking.

In this blog, we have discussed mobile app security best practices for safeguarding your mobile app with the latest security.

New and Emerging Practices for Mobile App Security

In 2024, the mobile app security market is expected to move forward. While establishing security, it’s essential to educate users about the potential threats so can rightly understand the mobile app security dangers and trends.

Best Practices For Your Mobile App Security

1. Code Encryption for App Protection

Mobile app developers use the right practice to create source code but even a single coding error can make the app vulnerable to potential bugs and attacks. With the help of public app copy, hackers take advantage of this vulnerability to tamper with your code.

Don’t worry. You can protect the code through encryption. Once code encryption is completed, you can be rest assured. That’s because even if your data gets stolen, hackers won’t be able to misuse it.


Here’s what you can do to encrypt your code for better app protection:

  • Strengthen your code’s security through code-signing practices.
  • Minify the codes that are likely to get stolen.
  • Design your code in a way so it can be easily updated.
  • Regularly test your code for bugs and fix them.
  • Make sure your code is agile so you can perform real-time updates.

2. Thoroughly Perform Security Checks

Before launching your app, you must test its functionality and usability. Additionally, perform security testing to detect potential vulnerabilities in your app. Even after the launch, your security team should regularly keep the app secure.


Here’s what you can do to thoroughly perform security checks:

  • Perform code audits and tests to check the app’s authentication and possible loopholes.
  • Detect data security issues by analyzing access controls before they become a major problem.
  • Use operating system emulators to understand how your app performs in a simulated environment.

Remember that app securing is a continuous process. Therefore, the tests need to be done regularly to detect possible threats. To conduct penetration testing, you can consult a network security specialist.

3. Backend Security

You may have security measures at the client-server interface but you must also protect your backend server from potential cyber attacks. This way, you can prevent any unauthorized access from the app’s database.


  • Create an encrypted storage system to store documents and data.
  • You encrypt the data while sending it back and forth between different systems and users.

4. Ensure Data Storage Security

The rising consumer mistrust will keep changing data rules and privacy laws. However, many mobile app development company fails to understand the importance of secure data storage.

When creating data storage systems, you must avoid sharing sensitive data with third parties, keyboard cache, IPC mechanism, app log, and user device. Avoid storing your app’s data and code locally.

Use encrypted containers to store data. Likewise, add an auto-delete feature to your data storage systems to automatically delete the data after a given period.


  • Encrypt user credentials and files through KeyStore, keychain, and SQL server.
  • Perform thorough analysis through data analytics.
  • Regularly key-encrypt your system to make key management a priority.
  • Use VPN, SSL, and TLS to secure your data in transit.

5. Get High-Level Authentication

Make sure your app only accepts alphanumeric passwords. Ask users to update their passwords regularly. By doing this, you can ensure that your app has a robust authentication system, which can keep hackers out on the user end.

Add an extra security layer to important apps, like banking by integrating fingerprints or retinal scans for biometric authentication. This will make it practically impossible for hackers to get past security measures.


  • Make sure your app only accepts strong, alphanumeric passwords.
  • Mandate the use of one-time passwords along with regular passwords to implement multifactor authentication.
  • Add an extra degree of protection by using biometric authentication.

6. Create a Strong API Strategy

APIs are the main channel for content and data as they maintain data flow between programs, cloud environments, and various users. That’s why you must protect your API to ensure the security of your web and mobile applications.

If your app functioning depends on someone else’s API, proceed with caution. That’s because you are depending on the security of their code. To reduce threats, make sure the APIs your app uses provide access to only certain areas of your app.


  • Make use of a gateway to secure your API.
  • To securely manage tasks like user authentication, you can use a central OAuth server.

7. Educate Your Users

As an app developer, you can only do a few things to protect the end customers. Regardless of your efforts, your users need to understand the importance of data protection and online self-defense. By teaching your consumers about certain precautions, you can educate them.


  • Download apps only from trusted sources, like the Play Store for Android devices and the App Store for iOS devices.
  • Make sure your password is strong at all times to prevent account hacking.
  • Use app locks to protect sensitive apps.
  • Enable auto-logout features on sensitive apps.
  • Never share passwords or OTPs with anyone.

Possible Mobile App Threats in 2024

Mobile app development companies need to be aware of emerging mobile app security risks to protect their apps. Below are the most common mobile app threats:

emerging mobile app security risks

1. Emerging Malware

Cybercriminals use malware to access private data in the mobile app. They can seriously jeopardize the security of devices and data by distributing malware through implanted code, fake apps, and duplicates. Understanding their techniques is essential to maintain safety.

2. Privacy Concerns

The rise in the use of mobile apps is also raising privacy issues. For instance, users are concerned about consent and data security. That’s why app developers should adhere to data privacy laws to keep users' trust.

3. Attacks in Supply Chain

APIs allow seamless data transfer between apps with ease. While it raises security concerns, adding third-party APIs to mobile apps can enhance the capabilities of mobile apps. You must evaluate APIs for robust security and authentication for guaranteed app security and user data dependability.

4. Phishing Attack

Phishing attacks make use of fake emails that claim to be from banks, credit card companies, or other respectable organizations. Their goal is to trick users into opening infected attachments or clicking on risky links is the goal.


The rising use of mobile apps is also raising cyber threats, which has made mobile security a matter of concern. Business owners today are advised to pay close attention to every possible threat to keep their apps secure and safe.
