A sandbox is a restricted execution environment that enables programs to access only certain resources and keeps problems that occur in the sandbox from affecting the rest of the server environment. Solutions that you deploy into a sandbox, which are known as sandboxed solutions, cannot use certain computer and network resources and cannot access content outside the site collection they are deployed in.

A farm administrator can block a sandboxed solution. A solution that is blocked does not run. Each sandboxed solution is identified by a hash result of the solution code. If the solution code is changed and redeployed, it will be seen as a new sandboxed solution and will be allowed to run even if the original is still blocked.

For more information about sandboxed solutions, see Sandboxed solutions overview (SharePoint Server 2010).

The Sandbox Solution framework provides a mechanism for executing user-provided code outside of the IIS worker process. The Sandbox Solution framework should not be used as a mechanism for enforcing security boundaries when executing user code. Sandbox Solutions are not supported as a security boundary with user code, especially code of unknown origin. We advise against executing Sandbox Solutions of unknown origins.
