Application hardening includes several techniques

Code confusion:

Code obfuscation disrupts the application code, making it more difficult to Reverse engineering the application. Therefore, by making the application harder to read, it becomes more difficult to target it, which also makes it more difficult to steal its IP or repackage it. Code obfuscation uses several techniques to protect applications. Software components and identifiers can be renamed. Virtual code that has never been used can be added, and strings can be encrypted. The code can be recompiled and run in an interpreter or virtual machine. Other code obfuscation techniques include reflection and packaging.

White box or white box Cryptography:

This method provides another option for utilizing local tools on modern platforms such as Apple iOS Keychain or Android Keystore. If a company needs to allow its applications to run on jailbreaking devices, this may be a useful encryption technique. In addition, if the intruder sees the default location of credentials on the device, such as Keychain/Secure Enclave for iOS or KeyStore for Android, they can use white boxes to attack the target.

Other tips:

Certificate fixation allows parties involved in the mutual authentication process to determine specific certificates, which can be used to counter Man-in-the-middle attack attacks.

Resource encryption includes encrypting application components, such as classes and strings.

Automatic expiration sets the deadline for users to log out after a period of inactivity.

Independent keyboard can be used to prevent Keystroke logging attempts, and rogue keyboard detection can be used to detect unauthorized keyboards.

Polymorphism is a way to change code to make Reverse engineering more difficult.

Application hardening Use Cases

A mobile banking application is a use case for application hardening. More and more mobile users rely on their devices for banking services. The fraudsters are waiting for an opportunity to exploit any security vulnerabilities they can find. Application hardening helps prevent fraudsters from developing malicious mobile banking applications, making it more difficult for attackers to succeed.

Mobile healthcare applications handle protected health information (PHI) regulated by the Health Insurance Circulation and Accountability Act (HIPAA). If remote medical applications leak patient data, medical service providers and other institutions may face severe penalties. Application hardening can ensure the maintenance of patient confidentiality and avoid HIPAA fines by ensuring that network attackers cannot access PHI.
