#125 What is a Sandbox?

Author: David Kopec, Rebecca Kopec October 2, 2023 Duration: 12:12

In software, a sandbox is an isolated environment that limits the resources that a particular application can access. Sandboxes are used to protect the security and privacy of the user. All Web apps and much consumer software running on modern operating systems like iOS, Android, macOS, and Windows runs in a sandbox. We also use our general definition of sandbox to discuss their use in software development. A sandboxed, development version of a software product doesn't affect the end users of the production version. Likewise, a sandboxed API doesn't allow a developer to accidentally complete a real-world transaction.

Note that we combine the sometimes more specific use of the term sandbox in computer security and sandbox environment in software development to form our own more general definition in this episode.
