Understanding OWASP Top 10

Welcome! Today we'll explore the OWASP Top 10, a crucial guide for web security.

OWASP stands for the Open Web Application Security Project. It's a non-profit foundation focused on improving software security.

The OWASP Top 10 is a standard awareness document for developers and security professionals. It lists the most critical web application security risks.

Injection is when untrusted data is sent to an interpreter as part of a command or query. This tricks the interpreter into executing unintended commands.

Think SQL, NoSQL, or Command Injection. In Node.js, if you build database queries or system commands using unsanitized user input, you're vulnerable.

An attacker could, for example, bypass login, alter data, or even execute system commands.
