The OWASP Top 10 is the industry-standard awareness document for web application security. Understanding these critical risks is essential for building secure applications.
What is the OWASP Top 10?
The Open Web Application Security Project (OWASP) Top 10 is a regularly updated report outlining the most critical security risks to web applications. It serves as a baseline for security testing and secure development practices.
The 2025 OWASP Top 10
1. Broken Access Control
Access control enforces policy such that users cannot act outside of their intended permissions. Failures typically lead to unauthorized information disclosure, modification, or destruction of data.
Prevention:
- Implement proper authorization checks
- Deny access by default
- Use centralized access control mechanisms
- Log access control failures
2. Cryptographic Failures
Previously known as Sensitive Data Exposure, this category focuses on failures related to cryptography which often lead to exposure of sensitive data.
Prevention:
- Encrypt all sensitive data at rest and in transit
- Use strong, up-to-date encryption algorithms
- Implement proper key management
- Disable caching for sensitive data
3. Injection
Injection flaws occur when untrusted data is sent to an interpreter as part of a command or query. SQL, NoSQL, OS, and LDAP injection remain prevalent.
Prevention:
- Use parameterized queries
- Validate and sanitize all input
- Use ORM frameworks
- Implement least privilege database access
4. Insecure Design
A new category focusing on risks related to design and architectural flaws. It calls for more use of threat modeling, secure design patterns, and reference architectures.
Prevention:
- Implement threat modeling
- Use secure design patterns
- Conduct security reviews
- Establish secure development lifecycle
5. Security Misconfiguration
Security misconfiguration is the most commonly seen issue. This is commonly a result of insecure default configurations, incomplete configurations, or misconfigured HTTP headers.
Prevention:
- Implement secure configuration baselines
- Remove unnecessary features and frameworks
- Keep systems updated and patched
- Use automated configuration scanning
