Defending against broken access control
Broken access control is the number one OWASP top 10 risk because it's widespread, relatively easy for attackers to exploit, and often high-impact when it fails. The good news? Most broken access control issues are preventable through clear authorization design, consistent implementation, and least-privileged configuration. We'll explore how to defend against these failures with practical, practical secure coding and configuration practices. The core principle is this. Authorization must be explicit, consistent, and enforced on the server for each relevant request. If the system relies on front-end checks, hidden buttons, conditional UI paths, or users won't find this URL, that's not access control, that's wishful thinking. Every action, every endpoint, and every resource needs a server-side authorization check that validates the user's identity and authorization context for that specific operation.
