Abstract

The invention relates to the communication security field. Aiming at the deficiencies of the prior art that the price of a memory which is used for an access strategy table is high and memories are wasted due to different strategy table items which are adopted according to different types of messages, the invention provides an access control method and a device thereof. In the method, a specific field which is relative with the access control is written into a customer field of a template, and a specific value is written into the customer field according to the rule of the access strategy table; the information of different types of messages is extracted according to the template and forms key word of the message. The value of the specific field of the message is written into the customer field of the key word. And the key word is matched with the rule. The action operation defined in advance is executed according to the matching result. The access control method and the device thereof have the beneficial effects that the memory can be effectively saved and the cost of the access control can be lowered.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to the field related to network security, specifically an access control method and device. Background technique [0002] An access policy entry refers to an entry that uses a specified behavior to process a specified type of packet. A policy entry consists of three parts: rule, mask, and action. Such as figure 1 Shown is a schematic diagram of policy entry rules and masks in the prior art. [0003] A rule refers to a pre-defined comparison object or comparison range. Each object to be compared is compared with the defined comparison object to see whether it is equal to or included in the comparison object. A rule is composed of a limited number of specific features, such as a Media Access Control address (MAC: Media Access Control), a Transmission Control Protocol address (IP: Transport Control Protocol), and the like. Each characteristic is called a field, and ea...
