How to Use Appdome SDKProtect to Secure Mobile SDKs

Introduction

In the ever-changing world of mobile application development, SDKs (Software Development Kits) play a crucial role in providing developers with pre-built tools, libraries, and APIs to enhance app functionality. However, the very features that make SDKs valuable also introduce significant security concerns due to their inherent complexity and broad accessibility.

SDKs typically encompass a vast array of functionalities packaged into an extensive codebase. This complexity can introduce multiple layers of potential vulnerabilities, as the deep and often intricate code structures provide numerous attack surfaces for malicious entities. Complex systems may contain security flaws that are harder to detect and can be exploited by attackers to perform actions like data breaches or unauthorized access.

SDKs are designed to be integrated into multiple apps, making them highly accessible and reusable across different development projects. While this promotes efficiency and functionality, it also means that SDKs are more exposed to misuse. Publicly available or widely used SDKs can be specifically targeted by attackers because a single vulnerability can potentially impact multiple applications at once.

What is Appdome SDKProtect? 

Appdome SDKProtect is a new service on Appdome that enables mobile SDK developers to quickly and easily create protected and threat-aware versions of their mobile SDKs, reducing fraud and ensuring compliance. SDKProtect is specifically engineered to secure mobile SDKs against a wide variety of threats. Below are the key features of SDKProtect:

• SDK Threat Shielding encrypts, obfuscates, and safeguards SDK components, fortifying them against cyber threats for enhanced security.
  • Obfuscate SDK Logic – Obfuscate SDK classes and methods to protect against malicious reverse engineering.
    * Excludes Specific Classes – List class or package prefixes to exclude from obfuscation.
  • Encrypt SDK Strings – Encrypts all SDK Java application strings.
  • Verify SDK Assets and Libs – Verify the authenticity of SDK native libraries and assets.
  • Protect SDK Resources – Verifies the authenticity of SDK native libraries and assets.
  • Encrypt SDK DBs – Protects data created by the SDK on the device by establishing a secure data container that also ensures that the application cannot access the SDK’s encrypted data.
  • Encrypt SDK Preferences – Protects SDK shared preferences so they cannot be modified by malicious actors attempting to change the way the SDK behaves.
  • SDK MiTM Defense – Validates the authenticity of communication sessions initiated by the SDK. This is achieved by pinning the server-side certificate and performing chain validation.
    • Enforce TLS Version – Enforces network connections to conform to TLS 1.2 version or higher.
    • Service Domain – Specify one or more hostnames by using standard wildcards to attribute the service you would like to protect.
• Mobile Risk Evaluation: Provides comprehensive coverage of SDK attacks, such as facial recognition bypass prevention, root and jailbreak detection/prevention, emulator detection, prevent hooking frameworks, block debuggers, block ADB and more.
• Threat Intelligence: Takes the power of Threat-Shielding and Mobile Risk Evaluation and combines it with the following visibility and control options.
  • Threat-Monitoring – combines the SDK protections with real-time attack monitoring and enterprise-grade intelligence via Appdome ThreatScope™ Mobile XDR.
  • Threat-Streaming – provides real-time telemetry data that can be streamed to the SDK back-end to create specific outcomes or responses when attacks happen.

By implementing these security measures, Appdome’s SDKProtect not only shields mobile SDKs from exploitation but also enhances the overall trustworthiness of the mobile applications that utilize the SDK.
