The OWASP MASVS (Mobile Application Security Verification Standard) is the industry standard for mobile app security. It can be used by mobile software architects and developers seeking to develop secure mobile applications, as well as security testers to ensure completeness and consistency of test results.

To complement the MASVS, the OWASP MAS project also provides the OWASP Mobile Application Security Testing Guide (MASTG), the OWASP Mobile Application Security Weakness Enumeration (MASWE) and the OWASP MAS Checklist which together are the perfect companion for verifying the controls listed in the OWASP MASVS and demonstrate compliance.

The MASVS Control Groups

The standard is divided into various groups of controls, labeled MASVS-XXXXX, that represent the most critical areas of the mobile attack surface:

  • MASVS-STORAGE: Secure storage of sensitive data on a device (data-at-rest).
  • MASVS-CRYPTO: Cryptographic functionality used to protect sensitive data.
  • MASVS-AUTH: Authentication and authorization mechanisms used by the mobile app.
  • MASVS-NETWORK: Secure network communication between the mobile app and remote endpoints (data-in-transit).
  • MASVS-PLATFORM: Secure interaction with the underlying mobile platform and other installed apps.
  • MASVS-CODE: Security best practices for data processing and keeping the app up-to-date.
  • MASVS-RESILIENCE: Resilience to reverse engineering and tampering attempts.
  • MASVS-PRIVACY: Privacy controls to protect user privacy.

MAS Testing Profiles

Starting on v2.0.0 the MASVS does not contain "verification levels". The MAS project has traditionally provided three verification levels (L1, L2 and R), which were revisited during the MASVS refactoring in 2023, and have been reworked as "MAS Testing Profiles" and moved over to the OWASP MASWE.

While we move things around and as a temporary measure, the OWASP MAS Checklist will still contain the old verification levels, associated with the current MASTG v1 tests. However, note that the levels will be completely reworked and reassigned to the corresponding MASWE weaknesses.
