OWASP (Open Web Application Security Project)

The Open Web Application Security Project (OWASP) is a nonprofit foundation dedicated to improving software security. It provides developers and security professionals with free, community-driven articles, methodologies, documentation, and tools to help them build and test secure web applications. OWASP is not a certification body or a software vendor; it's a global community that acts as a definitive resource for best practices in web security.

One of OWASP's most famous contributions is the OWASP Top 10, a regularly updated list of the ten most critical security risks to web applications.

Example: A developer is building a new user authentication system. To ensure the login process is secure, they consult the OWASP Top 10 list. They find that SQL Injection and Broken Authentication are high-risk vulnerabilities. Based on OWASP's guidelines, they implement measures to prevent these attacks, such as using parameterized queries to protect against SQL injection and ensuring proper session management to prevent unauthorized access. This use of OWASP resources helps them build a more resilient and secure login system.
