What is a Sandbox? Definition from SearchSecurity

A sandbox is an isolated testing environment that enables users to run programs or open files without affecting the application, system or platform on which they run.
Using a sandbox to detect malware offers an additional layer of protection against security threats, such as stealthy attacks and exploits that use zero-day vulnerabilities.
In general, a sandbox is used to test programs or open files without affecting the rest of the system.
Sandboxing is an important feature of the Java programming language and development environment, where the sandbox is a program area and set of rules that programmers need to use when creating Java code - called an applet - that is sent as part of a webpage.
Using a sandbox to isolate the code can help protect against malicious attacks and harm caused by buggy Java programs with unlimited access to memory or operating system services.
Sandbox restrictions strictly limit what system resources an applet can request or access.
The Java sandbox comprises the program area and a set of rules that programmers need to use when creating Java code sent with web content.
Sandbox restrictions set strict limits on what system resources an applet can request or access.
The sandbox can be conceived as a small area within a computer where an applet's code can play freely, but it's not allowed to play anywhere else.
A sandbox is implemented not only by requiring programmers to conform to certain rules, but also by providing code checkers.
In the original sandbox security model, the sandbox code is generally known as untrusted code.
In later versions of the Java Development Kit - the programmer's development environment - the sandbox has been made more sophisticated by introducing several levels of trust that users can specify for sandbox code.
Using a sandbox to test software changes before they go live reduces the chances of the updated software negatively affecting the production environment.
More advanced malware can check to see if it's running in a sandbox before executing.
Because a sandbox appears to be a complete system to the software, it usually can't detect that it's constrained to a virtual environment.
Windows Defender allows users to run the antivirus software in a sandbox.
Browser plugin content often depended on using a sandbox to screen content loaded by browser plugins, including the now-deprecated Microsoft Silverlight and Adobe Flash.
Microsoft Office has a sandbox mode to stop unsafe macros from tampering with a system.
Windows users can also use the built-in Windows Sandbox.
The sandbox isolates the applications, preventing them from tampering with each other.
