Programs are sandboxed if the access they have to other stuff in the computer is tightly restricted. Here is what Apple says in its developer library overview: For security reasons, iOS places each app (including its preferences and data) in a sandbox at install time. A sandbox is a set of fine-grained controls that limit the app’s access to files, preferences, network resources, hardware, and so on. As part of the sandboxing process, the system installs each app in its own sandbox directory, which acts as the home for the app and its data. This boils down to the effect that each application lives in its own little world with no knowledge of other programs and strong restrictions on writing outside of its own little world. This makes it very hard for malware to affect the operating system or other programs.
