In the IT realm, sandboxing is becoming increasingly popular. The sandbox technology is an offering that enables you to create an isolated test environment within a system. With this capability, a program can perform specific actions without the action causing any damage to the hardware, and primarily, sandboxing aims to protect your operating system by safeguarding it from any faulty code or malware. In a physical sandbox at a playground, children can create anything within the boundary without messing on the outside. Similarly, in sandboxing technology, the application code can be executed within a restricted environment, with minimum contact with the external environment. For instance, in a sandbox, JavaScript is free to add and modify elements on the page but could be restricted from accessing any external JSON file due to the presence of a sandbox feature called same origin.

The concept of sandboxing trails down to when the first PC systems were developed. In the 1970s, programmers leveraged sandboxes for test purposes and simulations. The programmers wanted to identify whether certain codes could work within a restricted and closed environment. Conventional security mechanisms like Hydra not just protected expensive hardware but showcased other advantages; sandboxing technology made it possible to record the problems that arose without isolation.

Several applications leverage sandboxing by default to protect the local operating system. For instance, the Windows 10 operating system has a built-in sandbox protecting the desktop from unauthorized code. Again, HTML 5 has a sandbox for protecting against the misuse of its iframe feature, while Java has its sandbox, like a Java applet running on a web page.
As the term implies, the primary target of a developer sandbox is to test and develop code in an isolated environment. Generally, a developer sandbox comprises a copy of a company’s production metadata.

Browsers evidently require much more added security protection. Fortunately, the majority of the browsers today come with built-in sandboxes where minimum end-user interaction is needed. Browser sandboxing is vital for identifying and separating malicious applications that run on the Internet from accessing local machines and their resources. Following are some of the popular browsers and their sandboxing capabilities:
See: Fundamentals of Browser, OS, and Device Fragmentation
Browser sandboxing refers to a security model that physically isolates Internet users’ browsing activity from the infrastructure, local computers, and networks. In order to prevent security breaches in your system or web application, developers must delineate how to deal with the issues, and this is what sandboxing assists in. The browser sandbox offers a safe virtual environment for testing suspicious and harmful codes or running third-party software without compromising the system data or local files.
The foremost goal of a sandboxed browser is to protect your machine from browser-associated risks. Thus, if a user downloads malicious software, the software gets downloaded into the browser’s sandbox, and every element inside it, including the harmful code, is wiped out upon closing the sandbox.

This conventional browser isolation technique runs the virtual browsers in the sandbox or the virtual machine on the user’s local infrastructure that aids in isolating data from external security threats and harmful browsing. The virtual browsers act as a protective barrier between external threats on the web and user machines. In this case, if any user visits a malicious site or downloads a harmful file, the threats are unable to reach the endpoint.
This sandboxing technique can be hosted over the cloud by an organization or any third-party provider. It involves a virtualization technique where the browser is run on a cloud-based server—both public and private cloud. In remote isolation, the user’s local system is free from browsing activities, while the browser sandboxing, filtering, and risk evaluation are executed on the remote server.
Remote isolation might often be expensive as it needs the allocation of resources to run a large volume of containerized browsers. However, utilizing third-party providers can prove to be cost-effective.

1. DOM mirroring —The browser isn’t entirely isolated from the user’s local system. However, the DOM mirroring technique filters out the malicious content and delivers the rest of the content to the user.
2. Visual Streaming — This technique offers complete remote browser isolation where visual streaming functions like Virtual Desktop Infrastructure systems in which a browser runs on the cloud-based server, and the visual output is displayed to the user’s local machine.

Today, the majority of the browsers have a sandbox already that improves the capabilities for protecting your system. Following are some of the primary web browsers and the respective sandboxes.
Firefox executes untrusted code within a sandbox to protect the local system from threats. The Firefox browser is sandboxed by leveraging the parent and child processes. While the users browse, potentially malicious programs run in the Firefox sandbox. This capability assists in limiting the contamination from malware in case of suspicious activities. The parent is a mediator between the child process and the other system resources during sandboxing.

This command returns the value of the current sandboxing level of Firefox. These level values indicate the unique sandboxing settings for every platform and process. Most of the processes have two active levels, which are the current setting and the lower (previously released) setting. Any level setting other than these two values do not carry a guarantee of altering security behavior—level settings are generally a release rollout debugging feature. Please read https://wiki.mozilla.org/Security/Sandbox for more details to see what the level means.
While launching the Edge sandbox browser Windows 10, the user is presented with a fresh desktop that has the Recycle Bin and Edge shortcuts. The page displays the Start menu and other icons, but those aren’t functional in this sandbox environment. It is highly recommended to open those in the main Windows 10 instead of sandboxed Windows 10. When the Edge browser sandbox is closed, the browser is no longer available. The user’s ISP may keep track of actions in the sandbox; however, this data is not auditable.

This sandbox is utilized by both Google Chrome and Microsoft Edge browsers. Similar to Firefox Sandbox, it runs in two parts, where the parts run the broker process and the target process of the code. Here the parent process is called the broker process, and the child processes are known as the target processes. Each code that is run by the child processes runs within the sandbox. On the other hand, the parent process acts as a mediator between the child process and computer resources to maintain the necessary supply of the resources.
