Security continues to be a significant area of concern for mobile apps. Mobile devices across both iOS and Android operating systems boast highly distributed components creating a range of app security issues. According to expert opinions, the vast majority of mobile apps are likely to fail elementary security tests.

Here we are going to explain key security mobile app issues and the ways to prevent them.

Key Security Threats for Mobile Apps

Let’s have a quick look at the leading security threats that mobile apps mostly suffer from.

Absence of Multifactor Authentication

Many users have the uncanny habit of using identical and easy-to-remember passwords for different apps. Now the breaching of one user’s password can lead to more extensive security compromises for multiple apps.

Multi-Factor authentication comes as a solution to this common security flaw. By allowing you to opt for two of three authentication measures, the reliance on passwords is reduced. So, even if the password is compromised, the account may not be hacked. When it comes to multi-factor authentication for app development India offers several excellent examples of app projects utilizing this security measure to the fullest.

Absence of Proper Encryption

Encryption refers to the process of transmitting data through a code that can only be decoded and viewed through the use of a secret key. Though encryption may work as a number-combination lock, it is still not completely secure from hackers.

This is why encryption should be utilized by considering all the measures that hackers can employ to decode the code.

Reverse Engineering

Reverse engineering is a threat that can take advantage of poorly programmed code. Understanding how the app functions from the metadata of the debugging code is a very common instance of this threat. Creating a fake app by reverse-engineering the code of the original app is a real threat.

Harmful Code Injection

Harmful code injected into your app through user-generated content can slyly harm the data security and completely ruin the app. Informs where there is no input limit, malicious users can inject code to process server requests leading to data theft and other security issues.

Insecure Data Storage

Data storage lacking security is a common problem with many apps. This can occur in several areas, including cookie stores, SQL databases, binary data stores, and others. Hackers gaining access to the app database can do all sorts of harm, including modifying the app.

Key Measures to Secure Mobile Apps from Threats

Now that we have a gross idea about the major security threats let us explain some effective measures to prevent these threats from settling in.

Strengthening Codes

The bugs and errors in the code make the app vulnerable to all sorts of security threats. The bugs and coding errors lurking deep inside the app allow the hackers to break through the security layer and get forced access to the app data.

This is why it is essential to ensure a strong coding structure. Apart from freeing the app entirely from bugs and errors, the code should be obfuscated and compressed to prevent reverse engineering.

Powerful Encryption

Any app sharing a gamut of critical data needs to safeguard data through powerful encryption. Encryption offers the promise of securing the data and preventing access to information even after it is stolen. But encryption should be both at the device level and the software level to prevent unsolicited access at all levels.

HTTPS Protocol

HTTPS is the secure internet protocol that gets the dual protection of TLS (Transport Layer Security) and SSL (Secure Socket Layer). These two cryptographic protocols offer the highest safeguard for the data while maintaining absolute integrity between the app and the server.

Apply Robust Authentication

For safeguarding the app from malicious attacks and intrusions, it is important to enforce multifactor authentication. The three key factors for authentication that apps should use include a password or PIN, a particular device, and biometric user data such as a fingerprint. When two of these factors are used in combination, the app enjoys better security.

Enhance Data Caching

The cached data stored in mobile devices helps in boosting app performance. But cached data can also expose the security-sensitive app data just because hackers can easily decrypt cached data.

To prevent this, create extra safeguards for the cached data. You can create a password for accessing cached data. Also, change the default settings to ensure that cached data is deleted every time the device is restarted.

Segregate App Data from That of User’s

For optimizing app security, you also need to segregate all your core or mission-critical app data from users’ data. This is a trusted measure to give safeguards to corporate information and critical developer data that hackers often target.

Thus, it is advisable to use a container-based model to ensure stricter security, preventing breaching access rules for the container at all levels.

External Libraries and APIs

Apart from offering some functional benefits, the external libraries from third-party developers can also expose the app to more security threats. For external libraries, it is advisable to evaluate the codes thoroughly before incorporating them into the app.

The third-party APIs can also be a security nightmare for your app. Besides ensuring meticulous implementation following the right procedures, evaluate the sources and whether the respective APIs are problematic for security or not.


As apps are continuously increasing in volumes and outreach, app security is becoming more challenging. All the steps and measures we have mentioned here have been tried and tested enough by the security experts and leading app projects. For robust app security, the approach must be proactive in detecting vulnerabilities and fixing them continuously.
