Plug-ins like Microsoft Silverlight and Adobe Flash isolate games and multimedia they run. If they become compromised, the damage they do will be limited. Self-contained applications run in lightweight virtual machines, sharing resources with the host OS kernel.īrowsers run in low-privilege sandbox mode. Most data centers use virtual machines to reduce cost. From a networking perspective, the virtual machine behaves like any other host on the network, with its own IP address and services that serve clients. If the guest manages to escape, it has escalated privilege and upgraded its shell to that of the host environment.Įxamples of sandboxes include the following.Įntire operating systems run within their own environments.
