Sandboxing
In plain terms
Running code in an isolated environment to contain risk.
Going deeper
Sandboxing executes untrusted code in a restricted space so it can't affect the rest of the system if it misbehaves. It limits potential damage.
Under the hood
Used in browsers, mobile apps, and malware analysis; isolation via containers, VMs, or OS restrictions.
Examples
Browser tabs, mobile app isolation, malware analysis, container isolation.
Think of it like...
Like testing a suspicious chemical in a sealed lab so a reaction can't escape.
