Abstract

The invention relates to the technical field of networks, in particular to a network access control method, system and device and a medium. The method comprises the steps of obtaining load balancing instance information; determining a first firewall rule matched with an IP type and a protocol type in the load balancing instance information; in the first firewall rule, determining a second firewall rule of which the source IP network segment is not included by the source IP network segment of the firewall rule with the higher priority; a routing table is generated based on the source IP network segment of the second firewall rule, and in the routing table, the routing table action corresponding to the source IP network segment is the action of the second firewall rule corresponding to the source IP network segment; receiving data; and querying the routing table and executing a corresponding routing table action. The technical problem that firewall software performance is not high is solved.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a network access control method, system, equipment and medium. Background technique [0002] Firewall is a common security protection technology in the network, which can effectively filter external illegal attack traffic to ensure the normal operation of services. Usually, firewalls need to set protection rules in multiple dimensions. For example, IP (Internet Protocol, Internet Protocol) type and protocol type need to be set to match exactly; mask match. In this way, due to the many and strict rules that need to be matched, the performance of firewall software is not high, and cannot meet the rapidly developing network requirements. Contents of the invention [0003] The purpose of the present invention is to provide a network access control method, system, equipment and medium, and solve the technical problem of low firewall software performance. [0004] The emb...
