This document discusses sandbox technology, which aims to create a secure virtualized environment for running applications in isolation. A sandbox allows untested code to be run safely without impacting the host system. Key components sandboxed include files, the registry, network interfaces, and processes. The document also describes a proposed system using isolated sandbox nodes connected through a mimetic internet to model network behavior and detect malware trying to determine if the environment is virtualized. The goal is to design a secure sandbox model for testing applications in Windows.
