In other words, the sandbox should work even if the user cannot elevate to super-user. Principle of least privilege: This should be applied both to the sandboxed code and to the code that controls the sandbox.On the other hand, it is OK to create application-level objects (abstractions) that have a custom security model. Let the operating system apply its security to the objects it controls. Do not re-invent the wheel: It is tempting to extend the OS kernel with a better security model.A description of what the sandbox does and doesn’t protect against may also be found in the FAQ. If you don‘t feel like reading this whole document you can read the Sandbox FAQ instead. The Linux implementation is described here, the OSX implementation here. This document covers the Windows implementation as well as the general design.
The architecture and exact assurances that the sandbox provides are dependent on the operating system. Sandbox leverages the OS-provided security to allow code execution that cannot make persistent changes to the computer or access information that is confidential. The sandbox objective is to provide hard guarantees about what ultimately a piece of code can or cannot do no matter what its inputs are. For a codebase as large and diverse as Chromium, reasoning about the combined behavior of all its parts is nearly impossible.
The key to security is understanding: we can only truly secure a system if we fully understand its behaviors with respect to the combination of all possible inputs in all possible states. This method accepts as a parameter the name or the desired path to capture the screenshot.Security is one of the most important goals for Chromium. Let's look at the following examples to understand these methods better: The save_screenshot method The following two methods are useful when taking screenshots using Selenium WebDriver: The captured screenshots maintain an up-to-date repository of the website information, for example, to monitor the price changes for a given product. This feature allows capturing screenshots from one or multiple websites and archiving them periodically. We may specify another path for the spawned screenshot. The captured screenshot is generated in PNG format and stored in the project directory by default. Selenium WebDriver allows taking a screenshot of a chosen web page opened in an automated browser. It allows the simulation of user interactions with the browser and comprises the following two main components: Selenium is mainly geared toward functional regression testing.
Selenium is a cross-platform toolset primarily designed to automate web application testing.
