OWASP MASVS (Mobile)

Overview

The OWASP Mobile Application Security Verification Standard (MASVS) is a framework designed to provide a baseline for mobile app security requirements. It helps organizations systematically identify and mitigate security risks in mobile applications across development and deployment phases.

Primary Objectives

• Enable consistent security assurance for mobile applications through standardized verification requirements
• Benefit security engineers, developers, auditors, and risk managers by providing clear security goals and controls
• Support informed decision-making and accountability by defining measurable security criteria and verification processes

Scope & Applicability

• Applicable to organizations developing or managing mobile applications across industries such as finance, healthcare, and retail, regardless of size
• Covers mobile app security domains including architecture, data storage, cryptography, authentication, network communication, and code quality; excludes broader mobile device security and backend infrastructure
• Requires foundational governance such as asset inventory of mobile applications and classification of sensitive data handled by the apps

Core Structure

• Composed of security verification requirements grouped into categories such as Architecture, Data Storage, Cryptography, Authentication, Network Communication, and Code Quality
• Organized hierarchically from security principles to detailed requirements and verification tests, facilitating systematic assessment
• Uses control identifiers and categories to map requirements, enabling traceability and integration with other security frameworks

How It Is Used

• Adopted through baseline implementation for new mobile apps or phased rollout for existing portfolios, often starting with pilot projects
• Supports assessment workflows including gap analysis, security audits, and formal attestations to verify compliance with defined controls
• Integrated into engineering workflows such as secure design reviews, software development lifecycle (SDLC) security gates, and backlog prioritization for remediation

Implementation Artifacts

• Derives security policies, standards, and procedures tailored to mobile app security requirements
• Includes a control library with mappings to other standards like NIST SP 800-53 and ISO/IEC 27001 for broader compliance alignment
• Generates evidence packages comprising audit tickets, configuration files, logs, and screenshots to demonstrate control implementation and testing

Measurement & Maturity

• Utilizes key performance indicators such as control coverage percentages and frequency of security testing to measure effectiveness
• Employs maturity levels to assess capability progression from basic compliance to advanced security posture
• Defines common baselines distinguishing minimum viable security controls from more comprehensive, risk-based implementations

Common Pitfalls

• Focusing solely on checklist completion without aligning controls to actual mobile app risk profiles
• Overextending scope leading to unnecessary complexity or under-scoping that misses critical security aspects
• Leaving controls without clear ownership, providing insufficient evidence, or maintaining outdated documentation

Integration & Mapping

• Provides crosswalks to frameworks such as OWASP ASVS, NIST, and ISO standards to facilitate integrated security management
• Integrates with governance, risk, and compliance (GRC) systems, security operations centers (SOC), incident response (IR), and SDLC processes
• Supports tooling integration including GRC platforms and automated control testing tools to streamline verification and reporting

When Not to Use It

• May be unsuitable for organizations seeking lightweight or minimal mobile security guidelines due to its comprehensive nature
• Less appropriate when regulatory requirements focus primarily on backend or network security rather than mobile app specifics
• In such cases, alternative staged approaches or focused mobile security checklists may be more practical
