Application Security Verification Standard
About
The OWASP Application Security Verification Standard (ASVS) is a framework designed to help organizations develop secure web applications by providing a structured set of security requirements. It serves as a guideline for developers, architects, testers, and security professionals to ensure security best practices are implemented during development.
What is OWASP ASVS?
OWASP ASVS is a set of security standards that provides a detailed framework for verifying the security of web applications. It defines three levels of security verification, making it useful for different types of applications based on risk and complexity.
It acts as a benchmark for security testing.
Helps organizations define and implement security controls.
Reduces security risks by providing structured security requirements.

Why is OWASP ASVS Important ?
Standardized Security Approach – Provides a common security framework to evaluate and improve security controls.
Improves Security Posture – Helps organizations proactively integrate security at different application layers.
Reduces Development Costs – By identifying vulnerabilities early, ASVS helps reduce security-related fixes in later stages.
Ensures Compliance – Aligns with regulatory requirements such as GDPR, PCI-DSS, and ISO 27001.
ASVS Security Verification Levels
OWASP ASVS defines three levels of security verification, depending on the application’s risk profile and security requirements.
ASVS Level
Description
Use Case
Level 1 (Basic Security)
Ensures basic security controls are in place. Covers low-risk applications and general security hygiene.
Public-facing applications with minimal security risks (e.g., blogs, marketing sites).
Level 2 (Standard Security)
Provides stronger security requirements for applications handling sensitive data.
Applications handling personal, financial, or confidential information (e.g., banking, healthcare).
Level 3 (Advanced Security)
Requires strict security measures for highly sensitive applications. Focuses on defense-in-depth security.
Critical applications such as government systems, financial platforms, and military software.
ASVS Categories and Controls
OWASP ASVS consists of 14 categories that cover different security aspects. Each category contains detailed security controls for verifying application security.
V1: Architecture, Design, and Threat Modeling
Ensures applications follow secure design principles.
Includes threat modeling, secure architecture, and risk assessment.
Helps identify attack vectors and potential vulnerabilities before implementation.
V2: Authentication and Session Management
Covers secure user authentication (password policies, multi-factor authentication).
Ensures secure session handling (session timeouts, token expiration, and re-authentication).
V3: Access Control
Implements Role-Based Access Control (RBAC) and Least Privilege principles.
Prevents unauthorized access, privilege escalation, and broken access control attacks.
V4: Input Validation and Sanitization
Prevents injection attacks (SQL Injection, XSS, NoSQL Injection).
Enforces strict input validation, encoding, and sanitization.
V5: Cryptography
Ensures the use of strong encryption algorithms for data protection.
Covers secure key management, hashing, and cryptographic storage.
V6: Stored and Transmitted Data Protection
Encrypts data at rest and data in transit using TLS, HTTPS, and strong cryptographic algorithms.
Protects sensitive data from exposure and unauthorized access.
V7: Error Handling and Logging
Ensures detailed logging for security events (authentication failures, unauthorized access attempts).
Prevents leakage of sensitive information in error messages and logs.
V8: Data Integrity Protection
Ensures data integrity through checksum validation, digital signatures, and tamper detection.
Protects software updates, API communications, and session tokens from manipulation.
V9: Communication Security
Enforces secure communication channels using TLS (HTTPS), HSTS, and certificate pinning.
Protects against Man-in-the-Middle (MITM) attacks.
V10: Malicious Code and Security Hardening
Protects against supply chain attacks, malware, and untrusted third-party dependencies.
Enforces secure coding guidelines and static analysis testing.
V11: Business Logic Security
Prevents abuse of business logic flaws (e.g., bypassing payment, unauthorized transactions).
Ensures proper rate-limiting and anti-automation measures.
V12: API and Web Service Security
Enforces secure API authentication (OAuth2, JWT, API Keys).
Protects against API abuse, rate-limiting bypass, and unauthorized access.
V13: Configuration and Deployment Security
Ensures secure deployment practices (CI/CD security, hardening configurations).
Protects against misconfigurations, default credentials, and insecure components.
V14: Mobile Security (Optional)
Covers mobile-specific security controls such as secure storage, encrypted communication, and biometric authentication.
Helps secure mobile applications from data leakage and unauthorized access.
How to Implement ASVS in Development Lifecycle ?
To successfully adopt ASVS, organizations should integrate it into the Software Development Lifecycle (SDLC):
Requirements Phase
Define security requirements based on ASVS levels.
Conduct threat modeling to identify application risks.
Development Phase
Implement secure coding practices following ASVS guidelines.
Use secure authentication, access control, and encryption mechanisms.
Testing Phase
Perform security testing (static analysis, dynamic testing, penetration testing).
Validate against ASVS checklist to ensure compliance.
Deployment and Maintenance
Apply secure configurations for web servers, databases, and cloud infrastructure.
Continuously monitor application security and apply regular patches.
