## Introduction

Internet Explorer provides new capabilities for application writers to add code to their HTML pages. With that greater power comes greater risk, in the form of malicious code. Internet Explorer introduces some new options and features designed to protect users and provide control over code behavior.

This document describes the potential security hazards of allowing controls to be accessed from scripts and initialized from untrusted data, and discusses hows controls can be marked as safe for these actions so that the user won't receive warning dialogs.
