Best Practices for Mobile App Security in 2024

With the turning pages of each day, our lives are becoming more and more dependent on mobile applications, which is posing security issues. We must be aware of the potential hazards and safeguard our data.

The current figure for online shoppers is 2.71 billion in the year 2024. Over the last several years, the percentage of online buyers has increased. The numbers for 2024 are 70 million more than those of the year before, a 2.7% year-over-year rise.

The importance of keeping mobile applications safe is growing with the number of online buyers. Unfortunately, antivirus is not included with mobile phones, hence users must update the software. As such, mobile apps have to take the necessary precautions to stop hacking.

We have covered mobile app security best practices in this blog to protect your app with the newest security.

What is Mobile App Security, and How is it Important?

A lot of people use mobile apps for many things, like banking and social media. This caused a boom in 2023 in mobile app security measures that prioritize protecting personal data first. Some improvements that stand out are Google’s BeyondCorp idea for strict access controls and Apple’s use of face ID instead of passwords to make mobile app security stronger. App shielding and code obfuscation have become more common as ways to make security even stronger against hacking and reverse engineering.

A multidimensional field, mobile app security seeks to defend mobile apps against many risks. Understanding how to secure your mobile app is essential to preserving data integrity and user confidence. Mobile app security is divided into three aspects. Here are they, alongside, showing the importance of mobile app security.

• User Data: Protecting user data against loss, illegal access, or leaking is important. Protecting user data requires the use of robust security measures, such as mobile app data encryption.

• Application Functionality: It is critical to ensure that applications work as intended without any exploitable flaws. Avoid interruptions, viruses, and unauthorized control by following secure coding and mobile app security best practices.

• Security of the Device: Due to user device engagement, mobile apps must avoid vulnerabilities. A detailed mobile app security checklist could help developers detect and fix problems.

How to Improve Mobile App Security in 2024?

Mobile app security vulnerabilities in 2024 are numerous, including malware attachments, data leakage, code tampering, phishing attacks, absence of multi-factor authentication, and poor encryption practices.

To address these threats, here are the mobile app security best practices for 2024.

1. Secure Coding for Mobile Apps

Secure coding practices are the base of secure mobile apps.

• Security Training: Security training helps developers write attack-resistant code. Buffer overflows and SQL injection attacks are common vulnerabilities that might harm your app if not addressed appropriately. Well-trained developers can design safe applications from the start because they can anticipate weaknesses and adopt best practices immediately. Regular training ensures developers are up-to-date on the latest dangers and prevention methods, protecting your mobile app.

• Code Signing: With code signing of mobile apps, you’re adding a digital signature that functions as an authentication mark. Users can be assured by this signature that the application is original and hasn’t been altered since you published it. Your app gets checked by their device to make sure everything is in order when they download it.

2. Mobile App Data Protection and Encryption

Any mobile application depends on its data, hence protecting it is essential. Sensitive user data is kept private and away from prying eyes by putting strong data encryption measures into place for data both at rest and in transit.

• Encryption: Passwords, credit card numbers, and other private information should all be encrypted using industry-standard techniques. This makes even if intercepted, the data inaccessible to unauthorized users. Common encryption techniques include RSA and AES-256.

• Put Safe Data Storage Options into Use: Trusted data storage options include safe cloud storage and protected databases.

• Data Minimization: Minimize data collection and storage to only the data that your app really needs to work. It is less susceptible to hackers the less data you have on hand. Give users choices over the data that is gathered and how it is used.

3. Secure Third-Party Libraries in Mobile Apps

If not carefully examined, third-party components could introduce vulnerabilities. Using reliable sources, doing regular audits, and knowing permissions are all necessary to make sure these components don’t turn into weak links in the app’s security chain.

• Update Management: Maintain the most recent iterations of the SDKs and libraries from outside sources in your app. Many times, security flaws found after the original release are addressed via updates. Use libraries with automatic updating features.

• Use Trusted Sources: Add libraries and SDKs only from reliable sources.

• Keep the Permissions Clear: Make sure third-party components don’t exceed what they need.

4. API Security

Important data can be unintentionally accessed by hackers when API access is not permitted and is poorly written. When programmers save permission data locally, they can use it later on when requesting APIs.

• Validation and Sanitization: Before the API processes any user input, validate and sanitize it. This reduces the possibility of injection attacks, in which malicious code is passed off as user input in order to take advantage of weaknesses in the backend systems of your app.

• HTTPS for Secure Communication: Make sure HTTPS (Hypertext Transfer Protocol Secure) is used for all connections between your mobile app and the backend servers. In transit encryption using HTTPS shields data against man-in-the-middle and eavesdropping attempts.

5. Testing and Evaluation

Cyber dangers are always changing, just as the digital world is. You can guarantee your user a safe experience at all times via regular testing and real-time monitoring that keeps applications up to date against the newest threats.

• Penetration Testing for Mobile Apps: TPenetration testing, or “pen testing,” simulates an app cyberattack. Find security weaknesses and exploit them before hackers do. Penetration testing’s main tasks are finding vulnerabilities and understanding how attackers might exploit them. Regular pen testing helps keep your mobile app safe and ready to face new attacks.

• Mobile App Threat Modeling: By considering possible security risks early on in the development process, threat modeling helps to mitigate such risks. In order to foresee and reduce security concerns, entails carefully assessing the app. As the app develops and gets new features, it’s important to reassess threat modeling, because it’s a continuous process. One way to prevent security holes in the future is to include threat modeling in the development process early on.

6. Development Process

Integration of security standards throughout the development lifecycle is the first step in ensuring strong security in mobile app development.

• Secure Development Lifecycle (SDL): The Secure Development Lifecycle (SDL) for mobile apps involves security throughout development. SDL starts early and maintains security concerns in mind throughout the project to reduce vulnerabilities and ensure software security. Preventative measures lower risks and improve your app’s resilience, making it a good security choice.

• DevSecOps: DevSecOps makes security everyone’s job throughout a mobile app’s development and operations. DevSecOps for mobile app development includes automation. Automated tools can quickly identify and fix security issues. These tools include vulnerability scanners, static code analyzers, and CI/CD pipeline connections. This simplifies development and reduces errors.

7. Advanced Security

“Modern problems need modern solutions”; hence, with cyber threats constantly evolving and rising in sophistication, updated security measures are necessary. Integrating advanced security solutions will keep applications secure from mobile app security vulnerabilities in 2024, even as attackers use newer methods.

RASP: Mobile app RASP (Runtime Application Self-Protection) detects suspicious runtime activity. RASP safeguards software while it’s running, unlike other security solutions.

RASP tracks the app and surroundings. This two-pronged approach finds holes in app security that could happen on any device, even ones that have been hacked or rooted. In addition, RASP can identify function hooking, when hackers attempt to manipulate or interrupt program activities. 

Best Tools for Mobile App Security Testing

Playing an active role in maintaining security in the ever-changing world of mobile app security is essential. The robustness of mobile apps against developing cyber dangers requires constant awareness and the adaption of security measures. NowSecure, which provides automated testing for both iOS and Android, is one of the best tools for mobile app security testing. Similar to NowSecure, Veracode’s all-inclusive platform includes analyzing software composition, static and dynamic analysis, and conducting manual penetration tests for mobile applications. Furthermore, Checkmarx is another well-known tool that aims to find vulnerabilities early on in the development process using static application security testing (SAST).

To improve the security of mobile apps as a whole, these technologies provide the necessary capabilities to find and fix any security issues.
