What are the important reasons Mobile App Security has Become a Top Priority for Developers?

The current outbreak of the pandemic has forced us to stay at home because of social distancing rules. These shifts in behavior led to a rise in the need for mobile apps on both Android and iOS. This widespread use is a security risk, even though most users do not understand the significance. This inexperience could exploit this inexperience. Mobile apps that are not secured present a significant risk for both developers and users since vulnerabilities that aren’t protected can be targets for hackers to carry out cyber-attacks or data breaches. There are more than 4.8 billion users of mobile phones, and if a virus does go infected, it could cause harm to the worldwide digital world. Security of mobile apps should be the primary concern, as any mobile application that is not secure has a high risk.


Mobile app security refers to protecting an app on mobile from fraudulent attacks such as malware, hacking, or other manipulative techniques.

Different techniques used to protect mobile apps address different kinds of cyber-attacks that mobile devices can create because of the apps installed within the device.

Mobile app security is the protection offered by an app from malware and phishing, among other dangerous hacker-related crimes.

Android is an excellent example. Being an open platform, it’s more susceptible to MITM attacks (man-in-the-middle) and security breaches or malware attacks than the iOS platform, which is restricted to Apple users.


The majority of the workforce works remotely. Some businesses employ freelancers that work on their laptops or personal computers for the job. This type of arrangement is a risk of attack.

One breach is enough to compromise the security of the company’s system and the customers. The most frequent targets for hackers are top-ranking executives in the organization since they have more significant amounts of data. So app developers need to examine the app’s security. Developers have to offer the most recent security tools to safeguard users’ privacy and data.

Security of mobile apps, when executed correctly, permits users to secure private and confidential data to secure themselves from losing data, virus and malware attacks, and lawsuits arising from insecure systems.


The most critical steps to secure the mobile app are:

Secure Database:

To secure your database, the storage should be encrypted completely and backups made using clear data access rules to avoid data breaches.

Developers need to keep passwords, databases, and other crucial information in a secure location regardless of whether it’s a device or a cloud-based server.

Secure Source Code:

Developers need to provide a superior security level to ensure hackers aren’t able to read your application’s code or even decipher it using different methods such as obfuscation or hiding the code.

For instance, Android has a Pro-Guard, a built-in feature that transforms confusing code characters. Because Android is an open-source platform, it is more vulnerable to cyber-attacks. Due to that, developers should ensure secure source code to eliminate any chance of alteration due to cyber-attacks.

Secure Data Transmission:

Developers need to encrypt their data to protect data transmission. It is crucial for applications that transmit data, such as the user’s personal information or bank details. Use secure channels through VPN tunnels SSL, TLS, or HTTPS for communication.

If you don’t encrypt the data, it could be a risk if encryption-decryption algorithms are weak. Hackers can easily decode them.

It is recommended to use secure cryptography to ward off sniffers, packet-sniffers as well as MITM attacks:

  •  Tests for input validation prevent data that isn’t formatted adequately from being stored in the app database. Validation tests for input are available in the majority of mobile frameworks. You can modify it to provide an additional layer of security to your application.
  • Data portability refers to the information accessible across various platforms or services. The most popular is Social Login, an option to log in to apps or websites using information from your Google, Facebook, Instagram, or any other login information.

These steps help developers create complete data security and add the protection of users’ privacy and authentication from day one.

The sign-up process is also more user-friendly and improves user satisfaction and experience.

Perform Penetration Testing:

Penetration testing is in which malware is replicated on your device to be capable of identifying weaknesses that could exploit. Often, this type of testing enhances the web application firewalls (WAF).

Test the code to determine any vulnerability to attack via injection. Adjust and alter the WAF Security policies and patch the vulnerabilities before launching your mobile application. Pen testing is distinct from standard software testing, but both are vital for ensuring the security of your app.

Set up a schedule to test and review the previously written code to check for flaws and then make changes.

Use Tokens for High-level Authentication:

Tokens are hardware pieces that securely transfer information regarding a person’s identity to the websites and applications. A security token electronically validates a person’s identity, keeping some personal data.

Developers of mobile applications use tokens to manage their users’ sessions effectively, and tickets of the same type can be either withdrawn or approved.

Use of complex passwords must be considered — applications are made to only accept medium to strong passwords using alphanumeric characters. The password must be maintained regularly, e.g., every six months.

OTP (one-time password or PIN) is valid for only one login session on the computer and other types of devices. It is possible to add it to secure sign-ups by adding two-factor verifications. That and an additional layer of security or encryption, making your application more secure.

Other authentication methods are used, such as retina scan or fingerprint and retina scan. Soon biometric access systems are likely to be introduced to enhance security measures. Biometric testing is also employed for other reasons, such as workplace wellness systems to establish employees’ health standards.


Here are some typical ways to build an extremely secure and safe mobile application:

Write a Secure Code:

Code is the most vulnerable component of any mobile app and can be hacked by hackers. Developers must write secure applications and perform code hardening and signing to ensure they create the highest quality code.

Encrypt the Data:

The encryption process involves simply taking texts (messages or emails) and converting them into a non-readable format called ‘ciphertext.’ It helps protect the confidentiality of digital information stored on a computer or transferred via the Internet. Once the intended recipient can access the message, the data is converted to the original format.

 Even if your information is stolen, hackers will be unable to read it and use it.

Be cautious when using Libraries:

Most mobile apps require third-party libraries to build code. Please do not depend on the app’s library uses, as many of them aren’t secure.

If you are using multiple libraries, it is essential to examine the code because the vulnerabilities in the library may impact your code and enable hackers to execute malicious code that can make the system crash.

Use Authorized API:

It is recommended to use an authentic API within your app’s code. It is suggested to obtain central authorization for all APIs for the highest level of security within a mobile application development system.

API calls are typically secured by a nifty API key and user’s credentials (often as access tokens). Mobile apps are typically less secure. Because they are installed on devices, hackers could also install apps on a device that they manage to modify the app and discover security holes.

That is why every API must require authentication at the app level.

Use High-Level Authentication:

The authentication mechanism is the most crucial aspect of mobile application security. Insecure authentication methods are the most vulnerable vulnerability in mobile applications.

Should view the authentication of users is extremely important in terms of security from a security point of view. The most commonly used authentication method uses passwords (medium to robust) that are not broken easily by hackers.


The mobile phone is a significant element of our lives. Many people do not realize the value of phones about the data it holds. Your phone contains a lot of information, from social media information to bank information. When you develop a mobile app, be sure the app doesn’t leave users vulnerable to attacks from malicious hackers or privacy violations. Security for mobile apps protects the app and the information within it. Even though users can install anti-malware or antivirus software or use VPNs if the app is attacked by hackers or infected, users will remain vulnerable to cyber-attacks. As an app developer on mobile, make sure you have robust security and data privacy within the app you create for your clients.
