Browser Security

Noun · Development

Definitions

  1. The collection of browser features and behaviors that isolate sites, enforce origin boundaries, manage permissions, and protect users from malicious web content. Browser security includes same-origin policy, sandboxing, CSP support, cookie rules, storage isolation, and many other mechanisms that web developers must understand when building apps.

    In plain English: The protections built into browsers that limit what websites and scripts can do.

    Example: "The team misread browser security constraints and assumed an iframe could access parent storage across origins when the platform explicitly prevented that."
