Sandboxing is a security technique used in computing to isolate programs and processes from the rest of the system. By creating a controlled environment, or "sandbox," applications can run without affecting other parts of the system. This helps prevent malware or harmful software from causing damage or stealing data. In addition to enhancing security, sandboxing is also useful for testing new software. Developers can run their applications in a sandbox to see how they perform without risking the stability of the main system. This approach allows for safer experimentation and debugging, leading to more reliable software releases.
