The invention discloses a regional authority control method, device and system based on a CIM model regional path, wherein the regional authority control method based on the CIM model regional path comprises the following steps: presetting a regional type capable of determining regional information and a regional attribute for recording the regional information; constructing a regional path list of the regional type and the non-regional type in the system based on the CIM model, and generating adapted regional path sorting according to the mutual association relationship; obtaining the regional information of a regional object according to the regional path sorting; and filtering according to the regional information of the object so as to remove an object which a client has no right to access and the associated relationships thereof. The device is used to implement the method. According to the method, the device and the system in the invention, the object region is derived according to a plurality of object traversal paths; the white list of an accessible region is obtained according to the IP address of the access client, the inaccessible data are filtered, and the CIS interfacedata access with the regional data access security control is transparently implemented.
