Embodiment Construction

[0027] The present invention will be further described below with specific embodiments in conjunction with the accompanying drawings.

[0028] The embodiment of the present invention provides a message processing method. The binding table in the prior art only includes KEY, such as source MAC, source IP, PORT and VLAN as shown in Figure 1, the embodiment of the present invention adds two One field is used to indicate the type of the binding table, one is the normal DHCP Snooping binding entry, the other is the abnormal DHCP Snooping binding entry, because a message does not hit the normal binding entry The binding entry created by extracting relevant information from the message is also called a blacklist binding entry; another field is used to indicate the frequency of the blacklist binding entry being hit. Through the statistics of the hit frequency of the user terminal information in the blacklist binding table entry, the attacker's behavior and information can be effectiv...

Abstract

The disclosed message process method comprises: receiving message including mark, determining whether hitting the normal bonding item according to the mark; if not, storing the mark in blacklist. This invention is benefit to locate and remove fault.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a message processing method, system and equipment. Background technique [0002] With the expansion of the network scale and the improvement of the network complexity, the network configuration becomes more and more complicated, and the situation that the location of the computer changes and the number of computers exceeds the IP address that can be allocated often occurs. The existing technology usually adopts DHCP (Dynamic Host Configuration Protocol, dynamic host Configuration protocol), to solve the problem of dynamic allocation of IP addresses, DHCP has the function of automatically assigning re-used network addresses and additional configuration options. [0003] DHCP encounters many security problems in the application process. The main means for attackers to use DHCP to attack include: DoS (Denial Of Service, denial of service) attack, DHCP Server sp...
