What It Is

The OWASP Top Ten is a community produced awareness document that ranks the most critical categories of web application security risk. It is not an exhaustive standard but a shared starting point that helps teams prioritize the issues that cause the most real world harm.

Representative Categories

  • Broken access control, where users reach data or actions they should not.
  • Cryptographic failures, such as weak or missing protection of sensitive data.
  • Injection, where untrusted input is interpreted as a command.
  • Security misconfiguration and vulnerable components, covering insecure defaults and outdated dependencies.

How To Use It

  • Treat it as a checklist and training aid, mapping each category to concrete controls in your stack.
  • Combine it with threat modeling and testing rather than relying on the list alone.
  • Revisit it as it is periodically updated to reflect changing risk trends.

Key idea

The OWASP Top Ten is a prioritization aid, not a finish line, so map each category to real controls and pair it with threat modeling and testing.
