Code hardening: Mobile code protection

Code hardening is the process of protecting software from reverse engineering, tampering, and any unauthorized access by making the underlying code difficult to read, analyze or modify.

Increase your mobile code protection, secure sensitive information and prevent IP theft.

What is mobile code protection?

Mobile code protection defends mobile app code against reverse engineering and tampering. This includes techniques such as code obfuscation, encryption, and ensuring mobile app integrity. Mobile code protection helps developers safeguard their app’s code and prevents unauthorized access.

What is static analysis?

Using decompilers or disassemblers, threat actors can expose your mobile app’s internal logic and gain insight into its functionality. With this knowledge, threat actors can reverse engineer your app, steal your IP or sensitive data and identify ways to break down related systems’ and apps’ security.

Why is static analysis a threat?

After they’ve uncovered your app's internal logic, an attacker can do a lot of damage. They can steal proprietary information, extract credentials and API keys that will give them access to other systems and apps, unlock premium portions of the app, and more. Leveraging mobile application code hardening provides protection against static analysis to prevent these outcomes and preserve your app's integrity, your data and your brand’s reputation.

Code hardening essentials

Code hardening techniques render your code illegible without affecting its functionality, ensuring that malicious users who decompile your app won’t be able to easily interpret its internal logic. This category of mobile app security includes strategies such as encryption, removing certain metadata, renaming classes and variables, adding ancillary code, altering the structure of the code and more — all without altering the function of the code or the end user experience in a meaningful way.

Less than 10% of the top 3,000 financial services Android apps use additional code protection techniques beyond name obfuscation, leaving them open to reverse engineering.

Code hardening techniques

Security for every stage of the software development lifecycle.

Too often delayed to the end of the development lifecycle, application hardening security needs to be considered right from the start. As your app development progresses, testing, feedback and monitoring help you to ensure the highest possible level of mobile code protection.

Develop

Mobile app security is most effective when it’s considered from the outset of the development lifecycle, which includes making informed design choices, following best practices as well as early rounds of testing and refinement. Ultimately, engaging in secure software development practices identifies security risks early, when they’re quick and cheap to fix, rather than after deployment.

Protect

Now that your app is implemented, it’s crucial that you incorporate defenses against reverse engineers in order to protect your intellectual property, prevent counterfeits and secure your data and your brand’s reputation. App shielding techniques like code hardening and runtime application self-protection (RASP) ensure that your mobile app can’t be easily reverse-engineered or tampered with.

Test

You wouldn’t release your app without testing its functionality; nor should you without testing its security. Pentesting, or penetration testing, is often performed by third-party experts to attempt to identify security gaps in your app and gain insight into its internal logic, just as a threat actor would. A complement to pentesting is AppSweep, Guardsquare's automated mobile application security testing (MAST) tool.

Monitor

Now it’s time to monitor your app's usage after its release, and track related threats in real-time. What are threat actors’ preferred attack vectors? How can you evolve to improve your defenses? Real-time threat monitoring can provide the answers.

Mobile app code hardening FAQs

Mobile application code hardening is crucial in delaying tampering and reverse engineering attempts. It aims to create a robust defense against various security threats, including unauthorized access, data breaches, and the introduction of malicious code.

Protecting data with mobile app encryption is crucial for ensuring the confidentiality and integrity of sensitive information stored or transmitted by your mobile application. Encryption refers to the process of converting understandable data into a coded or unreadable form.

Code hardening is the process of strengthening an application’s code against reverse engineering, tampering, and exploitation by adding multiple layers of protection techniques embedded in the code.

Code hardening is important because it makes apps more resistant to reverse engineering and tampering, protecting sensitive data, intellectual property, brand reputation and user trust.

Code hardening works by applying techniques like obfuscation, encryption, runtime checks, and integrity verification to make code difficult to analyze or modify.

Examples of code hardening techniques include different types of obfuscation techniques, string and class encryption and runtime protections.
