The invention discloses a mobile data security protection method based on a security sandbox. The mobile data security protection method based on the security sandbox comprises the following steps: the security sandbox is used for requesting resources to the server; and the security sandbox establishes a connection with the server side resources through a data security transmission channel and transmits data; wherein the way that the security sandbox establishes the connection with the server side resources through the data security transmission channel and transmits the data is that the security sandbox establishes the connection with a server on the server side through the data security transmission channel and transmits the data to the server, the server side comprises the servers, theservers comprise a base board management controller, and a number of security sandboxes are connected with one server in the server side. By means of the mobile data security protection method based on the security sandbox, the problems in the prior art that the task of the base board management controller increases and the base board management controller is overwhelmed caused by sending a mass of messages to the base board management controller in a short time, the maintenance of the server cabinet and the servers is very complicated, and it is very complicated when the server cabinet must be dismantled are effectively avoided.
