Study Notes
OWASP Mobile Application Security Testing Guide Overview
- OWASP MAS advocates are companies that significantly contribute to OWASP Mobile Application Security Verification Standard (MASVS) and Mobile Application Security Testing Guide (MASTG).
- To be recognized as MAS Advocates, companies must demonstrate clear adoption, provide high-impact contributions, and spread awareness through presentations and promotions.
- Benefits for MAS Advocates include logo display on official materials, acknowledgment in releases, and linked blog posts.
Mobile App Definition and Taxonomy
- The term "app" refers to applications on mobile operating systems, including native, hybrid, and web apps.
- Native Apps: Developed using SDKs specific to OS (e.g., Objective-C/Swift for iOS, Java/Kotlin for Android).
- Native apps provide high performance and reliability, adhering to platform-specific design principles.
- Native apps can access device components (camera, sensors) but are limited to single platforms; separate codebases are needed for Android and iOS.
Mobile App Security Testing
- Mobile app security tests are part of broader security assessments, examining both client-server architecture and APIs.
- Two contexts for testing:
- Classical security tests near the project’s end, identifying issues in near-final products.
- Continuous security requirements and tests integrated from the software development life cycle.
Testing Principles
- Black-box Testing: Tester has zero information about the app; simulates a real attacker’s experience.
- White-box Testing: Tester has full knowledge of the app (source code, documentation), allowing more sophisticated test cases.
- Gray-box Testing: Combined approach with limited information available, offering a balance in testing scope and cost.
- Sensitive data includes authentication info, Personally Identifiable Information (PII), sensitive technical data, and any data requiring protection by law.
Intelligence Gathering
- Involves collecting environmental (organizational goals, relevant industry, stakeholders) and architectural information (app functionality, OS and network details).
- Understanding external risks aids in identifying potential attack targets.
Mapping the Application
- Security testers map app structure, entry points, features, and data flow.
- Using documentation (architecture diagrams, specifications) facilitates quicker and more effective penetration testing.
- Static Application Security Testing (SAST) tools can identify vulnerabilities in the source code, while Dynamic Application Security Testing (DAST) tools assist black-box testing.
- Manual analysis complements automated tools, as intuition often plays a critical role in security evaluation.
- Threat modeling should be incorporated early in the software development life cycle to support vulnerability identification effectively.
