Describe cookies and frame busting.


Tiny Data Files: Cookies are like small text files stored by your web browser on your computer.

First-Time Visit: When you visit a website for the first time, a new cookie is made. It collects info that the website owner can later access.

Single File Storage: Some browsers store all cookies together in a single file.

Subdivided Info: The info in this file is split into individual parts, called attributes.

Frame Busting:

No Sub-Frames Allowed: Frame busting is like a web page’s rule saying, “Don’t load me in a smaller frame inside another page.”

Defense Move: It helps prevent tricky things like click-jacking, where a bad website might try to trick you into clicking on things without you realizing.

Yahoo Example: Think of Yahoo’s sign-in seal, which shows a special image to prove it’s the real login page. Frame busting is needed to make sure this image appears only when it’s supposed to.

Image Authentication: Without frame busting, even if the image is right, it might show up on a fake Yahoo page.

Growing Threats: As new tricks like dragging and dropping data into frames appear, frame busting becomes even more crucial for keeping things secure.
