The OWASP Top 10 is the list of the ten most common security risks that can occur in web applications. OWASP is the "Open Web Application Security Project", a non-profit organisation dedicated to improving the security of software applications.

The OWASP Top 10 includes different types of security risks such as injection and cross-site scripting (XSS). The current OWASP Top 10 are from 2021:

  • A01:2021-Broken Access Control
  • A02:2021-Cryptographic Failures
  • A03:2021-Injection
  • A04:2021-Insecure Design
  • A05:2021-Security Misconfiguration
  • A06:2021-Vulnerable and Outdated Components
  • A07:2021-Identification and Authentication Failures
  • A08:2021-Software and Data Integrity Failures
  • A09:2021-Security Logging and Monitoring Failures
  • A10:2021-Server-Side Request Forgery

Consideration of the OWASP Top 10 can help improve security compliance, as many industry and regulatory standards reference the OWASP Top 10 - such as the Payment Card Industry Data Security Standard (PCI DSS) in its requirements for secure software development and penetration testing.
