Abstract

The invention provides a method and a system for controlling read-write authority to realize data security ferry, and electronic equipment. The method comprises the following steps: an external network module sets an external equipment interface allowing access to the external network module; and the external network module receives external data from the external equipment interface and controls the read-write permission of the external equipment interface. According to the data security ferrying method provided by the invention, the external network module sets the external equipment interface allowed to access, receives the external data from the external equipment interface, and controls the read-write permission of the external equipment interface; therefore, the situation that an existing rail transit system is invaded by external malicious viruses, malicious codes and the like due to the fact that interface management is not standard, external equipment is randomly connected and the like is prevented, the safety of external data connected into a rail transit system network is guaranteed, and therefore risks caused by the complex structure of the rail transit system are effectively made up. And a technical support is provided for establishing and perfecting a data security migration protection system based on a rail transit system.

Description

technical field [0001] The invention belongs to the technical field of data transmission, and in particular relates to a method, a system and an electronic device for controlling read and write permissions to realize safe data ferrying. Background technique [0002] The existing rail transit system has a large number of equipment, and it is very easy to be damaged by external malicious viruses and malicious codes due to irregular interface management and random connection of external devices. It is impossible to guarantee the access to external data in the rail transit system network. Security, thus bringing security risks to the internal network of the rail transit system. [0003] In view of the vulnerability of the rail transit system and the importance of safe operation, it is necessary to take into account the data security of the rail transit system, and establish and improve a data security migration protection system based on the rail transit system. Contents of th...
