Access control method, device and system as well as computer readable storage medium

Abstract

The invention provides an access control method, a device and a system as well as a computer readable storage medium and belongs to the field of network technology. In the access control method, transfer equipment can receive an access data packet sent by access equipment, then an authority attribute identification is set for the access data packet based on a source address of the access data packet to obtain a target data packet, and finally the target data packet is sent to the target equipment and the target equipment can process the target data packet on the basis of an authority attributerepresented by the authority attribute identification, so that an authority list does not need to be stored in the target equipment, the target equipment also does not need to determine an authorityon the basis of the authority list, an access authority of the target data packet can be determined directly on the basis of the authority attribute identification contained in the target data packet,then processing on the data packet sent by the access equipment is realized, then less storage space of the target equipment is occupied, and influence on performance of the target equipment and influence of the target equipment on normal processing of the data packet are avoided.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to an access control method, device, system and computer-readable storage medium. Background technique [0002] At present, with the continuous development of network technology, there are more and more devices in the network system. In order to improve the security of the network, it is often necessary to restrict the access rights of the devices in the network system. For example, for storage with a higher security level Data server, only some servers are allowed to access. [0003] In the prior art, when access restriction is performed, a permission list is usually stored in the target device, and the permission list records all network protocols (IP) of access devices that are allowed to access the target device and are not allowed to access the target device. Address, when the target device receives the data packet sent by the access device, it will first obtain t...
